VAT is a value-added tax applied across the supply chain and ultimately paid by the final consumer.

How do I add VAT to a net amount?

Multiply the net amount by 1 + VAT rate / 100.

How do I remove VAT from a gross amount?

Divide the gross amount by 1 + VAT rate / 100 to recover the net amount.

What is the VAT amount on an invoice?

It is the difference between the gross total and the net amount.

What is the difference between VAT and sales tax?

VAT is collected throughout the supply chain with input and output tax accounting, while sales tax is typically charged only at the final retail transaction.

Why do some countries have reduced VAT rates?

Reduced rates are often used for essential goods or policy-priority categories such as food, books, or public transport.

What is a VAT-registered business?

It is a business authorized or required to charge VAT on taxable sales and usually reclaim VAT on eligible business purchases.

Are VAT and GST the same?

They are closely related consumption tax structures. GST is often a specific national implementation of value-added taxation.

Does VAT apply to exports?

Many systems zero-rate qualifying exports, but documentation and filing rules are strict and jurisdiction-specific.

Why does this calculator include country presets?

Because VAT rates vary significantly across countries and preset rates reduce input errors for common scenarios.

How to understand and use this calculator

Quick Answer

What is VAT? Value-Added Tax (VAT) is a consumption tax applied to goods and services at each stage of production. The final consumer bears the full tax burden.

Key formulas:

Add VAT: Gross = Net × (1 + VAT Rate)
Remove VAT: Net = Gross ÷ (1 + VAT Rate)
VAT Amount: VAT = Gross − Net

Simple example: Net price = €100, VAT rate = 20%.

VAT amount: €100 × 20% = €20
Gross price: €100 + €20 = €120

Quick reference:

20% VAT on €100 → €20 VAT, €120 gross
Remove 20% VAT from €120 → €100 net, €20 VAT
23% VAT on €100 → €23 VAT, €123 gross

Use the VAT Calculator

To use the calculator with VAT:

1. Enter the net price (price before VAT), or the gross price if removing VAT.

2. Enter the VAT rate — pick a country preset (with reduced rate where available) or a custom rate.

3. Select Add VAT, Remove VAT, or Find VAT Rate.

4. Review the VAT amount, gross price, and step-by-step work.

Example input (Add VAT): Net Price = €100.00, VAT Rate = 20%.

Output:

VAT Amount = €20.00
Gross Price = €120.00
Step-by-step work: €100 × 20% = €20 → €100 + €20 = €120

Example input (Remove VAT): Gross Price = €120.00, VAT Rate = 20%.

Output:

Net Price = €100.00
VAT Amount = €20.00
Step-by-step work: €120 ÷ 1.20 = €100

Introduction to Value-Added Tax (VAT) and Global Taxation

Value-Added Tax (VAT), alternatively designated in some tax jurisdictions as Goods and Services Tax (GST), represents a pervasive, consumption-based tax levied incrementally on the value added at each consecutive stage of production, distribution, and final retail delivery of goods and services. Conceptually, it functions as an indirect tax because it is not paid directly by the taxpayer to the state treasury; rather, it is collected from the final consumer by registered merchants, who act as intermediaries for the fiscal authority.

First introduced in the mid-20th century in countries like France, VAT has expanded to become the primary consumption tax framework in over 170 countries, including the entirety of the European Union, the United Kingdom, Australia, Canada, and major economies throughout Latin America and Asia. In contrast to a flat retail sales tax, which is levied strictly at the point of final transaction to the end customer, VAT is collected dynamically throughout the supply chain. Because businesses are permitted to claim credits for the VAT they pay on business-related inputs, the net tax burden cascades down to settle exclusively upon the ultimate consumer, who does not have input reclamation privileges.

Navigating these regional VAT laws is a critical operational requirement for modern corporations engaged in cross-border commerce. Rates vary widely by jurisdiction, ranging from standard rates of under 10% in countries like Switzerland and Singapore, to standard rates exceeding 20% across much of Western Europe, peaking at 27% in Hungary. Many countries additionally apply reduced rates, super-reduced rates, or zero-rates to specific categories of products, such as basic foodstuffs, essential pharmaceuticals, and children's apparel, adding significant complexity to payroll and corporate accounting workflows.

The Mathematical Formulations: Adding and Removing VAT

To perform VAT adjustments, accountants and businesses must navigate two discrete operations: adding VAT to a net cost (tax-exclusive calculation) and stripping VAT from a gross cost (tax-inclusive calculation). Understanding the algebraic derivations of these operations prevents rounding discrepancies and ensures exact reporting on invoice sheets and corporate tax filings.

Let V represent the standard VAT rate expressed as a percentage (e.g., 20% is entered as 20). Let N represent the net price of goods or services before tax, T represent the absolute tax amount, and G represent the gross price inclusive of tax. Under these parameters, the formulas are structured as follows:

To add VAT to a net amount, the absolute tax is computed by multiplying the net figure by the rate percentage divided by 100:

T = N × ( V/100 )

The final gross amount is the simple summation of the net value and the tax amount, which is represented by:

G = N + T = N × ( 1 + V/100 )

Conversely, if you are presented with a gross price that already contains VAT and need to isolate the underlying net value (removing VAT), you cannot simply subtract the tax rate from the gross sum. Because the tax was originally calculated on the smaller net base, subtracting the same percentage from the larger gross base will yield an under-calculation. Instead, we must invert the formula:

N = G/(1 + V/100) = (G × 100)/(100 + V)

Once the net amount is isolated, the VAT amount component can be found by subtracting the net from the gross, or by applying the isolated rate ratio directly:

T = G - N = G × ( V/(100 + V) )

Step-by-Step Manual Calculation Examples

To ground these theoretical algebraic concepts in day-to-day business accounting, let us work through two detailed, step-by-step practical examples using common real-world variables.

Example 1: Adding 20% VAT to a Net Service Agreement (Tax-Exclusive). Suppose a digital consulting firm in the United Kingdom signs a project agreement worth a net value of £2,500 and must charge the standard UK VAT rate of 20% on the invoice. How do you construct the final bill?

Step 1: Identify the variables. Here, Net Amount N = 2,500 and VAT Rate V = 20 .

Step 2: Calculate the absolute tax component using the tax addition formula:

T = 2,500 × ( 20/100 ) = 2,500 × 0.20 = 500

Step 3: Add the tax amount to the net amount to determine the final gross invoice price:

G = 2,500 + 500 = 3,000

The firm will charge a gross price of £3,000 to the client, recording £2,500 as operating revenue and holding £500 in a liability account to be paid to HM Revenue Customs (HMRC).

Example 2: Removing 27% VAT from a Gross Purchase Receipt (Tax-Inclusive). Suppose an international business traveler purchases a high-end monitor in Budapest, Hungary, for a total retail shelf price of 127,000 Hungarian Forints (HUF). Since Hungary levies a standard VAT rate of 27%, how much of that receipt represents the actual item cost, and how much is value-added tax?

Step 1: Identify the variables. Gross Amount G = 127,000 and VAT Rate V = 27 .

Step 2: Calculate the net amount by dividing the gross price by 1 + V/100 :

N = 127,000/(1 + 0.27) = 127,000/1.27 = 100,000 HUF

Step 3: Subtract the net amount from the gross price to isolate the tax portion:

T = 127,000 - 100,000 = 27,000 HUF

The retailer received 100,000 HUF for the product, and 27,000 HUF was collected on behalf of the Hungarian National Tax and Customs Administration.

Economic Cascades: Input VAT vs. Output VAT

Understanding how VAT flows through a supply chain reveals why it is considered an efficient tax mechanism that avoids double taxation (tax-cascading). The entire process is driven by the interaction between Input VAT and Output VAT.

Output VAT refers to the value-added tax that a business charges its customers on sales of goods and services. Input VAT is the value-added tax that a business pays to other suppliers for raw materials, inventory, utilities, and professional services required to run its operations. Every quarter or month, a registered business prepares a VAT return. The business calculates the total Output VAT collected from clients and subtracts the total Input VAT paid to suppliers. If Output VAT exceeds Input VAT, the business pays the difference to the government. If Input VAT exceeds Output VAT, the business claims a tax refund or credit.

Let us trace a simplified wood manufacturing supply chain with a 10% VAT rate. First, a forester cuts timber and sells it to a lumber yard for $100 plus 10% VAT ($10). The forester pays $10 to the tax office. Next, the lumber yard processes the timber into planks and sells them to a furniture maker for $200 plus 10% VAT ($20). The lumber yard collects $20 Output VAT but offsets it with the $10 Input VAT paid to the forester, sending $10 net to the government. Finally, the furniture maker builds a table and sells it to a homeowner for $500 plus 10% VAT ($50). The manufacturer collects $50, subtracts the $20 Input VAT paid to the yard, and pays $30 to the government. The homeowner pays $550. The government receives $10 + $10 + $30 = $50, which is exactly 10% of the final $500 value.

Global Invoice Compliance Standards

To legally collect VAT and enable business customers to reclaim their Input VAT, tax authorities enforce strict document compliance rules. A standard compliant tax invoice must contain specific fields to be recognized in audits.

First, it must be clearly labeled as a "Tax Invoice". It must feature a unique, sequential invoice identification number and the document issue date. Second, it must show the full name, physical address, and Tax Registration Number (such as a VAT Number, GSTIN, or ABN) of the supplier. Third, the customer's name, address, and VAT registration number (if applicable for reverse charge or cross-border sales) must be clearly stated.

Furthermore, the invoice must list a line-by-line description of the goods or services, including quantity, unit price excluding VAT, the specific VAT rate applied to each item (since an invoice can contain mixed rates, like standard and exempt items), the total net subtotal, the aggregated VAT amount separated by rate band, and the final gross total due. Missing any of these details can invalidate the invoice, preventing business buyers from recovering their tax expenses.

VAT vs Sales Tax — What's the Difference?

Feature comparison:

Type: VAT — multi-stage tax. Sales tax — single-stage tax.
When charged: VAT — every stage of production. Sales tax — only at final sale.
Who bears it: Both — the final consumer.
Visibility: VAT — less visible (often included in the sticker price). Sales tax — very visible on the receipt.
Administrative cost: VAT — higher. Sales tax — lower.
Where used: VAT — Europe, Asia, Australia, Canada (GST). Sales tax — United States (state level).

Example comparison (10% rate, four-stage supply chain): raw materials ($100 value added, $10 VAT / $0 sales tax), manufacturing ($50 value added, $5 VAT / $0 sales tax), wholesale ($100 value added, $10 VAT / $0 sales tax), retail ($100 value added, $10 VAT / $35 sales tax). Total tax collected: $35 either way.

Key takeaway: both result in the same total tax, but VAT is collected in stages while sales tax is only collected at the final sale. Need US sales tax instead? Try the Sales Tax Calculator.

VAT vs GST — What's the Difference?

Feature comparison:

Definition: VAT — tax on final consumption. GST — tax on the supply of goods/services.
Linked to: VAT — the sales moment. GST — the point of supply.
Operation: VAT — offline, summary-based. GST — online, transaction-based.
Responsibility: VAT — seller collects the tax. GST — purchaser records the tax.
Double taxation: VAT — can occur on excisable goods. GST — generally subsumed, avoiding double taxation.
Where used: VAT — EU, UK, and many other countries. GST — Australia, Canada, New Zealand, Singapore, India.

Key insight: VAT and GST are often used interchangeably, but they have different implementations. GST is generally simpler and more efficient.

How to Add VAT (Net to Gross)

Formula: Gross Price = Net Price × (1 + VAT Rate)

Step-by-step example: Net price = €80, VAT rate = 20%.

Step 1: Convert to decimal: 20% ÷ 100 = 0.20.

Step 2: Add 1: 1 + 0.20 = 1.20.

Step 3: Multiply: Gross = €80 × 1.20 = €96.

Answer: Gross price = €96

More examples:

Net €100 at 20% → Gross €120, VAT €20
Net €50 at 23% → Gross €61.50, VAT €11.50
Net £75 at 20% → Gross £90, VAT £15
Net €200 at 19% → Gross €238, VAT €38

How to Remove VAT (Gross to Net)

Formula: Net Price = Gross Price ÷ (1 + VAT Rate)

Step-by-step example: Gross price = £120, VAT rate = 20%.

Step 1: Convert to decimal and add 1: 1 + 0.20 = 1.20.

Step 2: Divide: Net = £120 ÷ 1.20 = £100.

Answer: Net price = £100

More examples:

Gross €120 at 20% → Net €100, VAT €20
Gross €61.50 at 23% → Net €50, VAT €11.50
Gross £90 at 20% → Net £75, VAT £15
Gross €238 at 19% → Net €200, VAT €38

How to Figure Out VAT — Different Scenarios

Scenario 1: Adding VAT. A product costs €80 before VAT. VAT is 23%. VAT = €80 × 23% = €18.40. Gross = €80 + €18.40 = €98.40.

Scenario 2: Removing VAT. You paid €120 for a product including 20% VAT. Net = €120 ÷ 1.20 = €100.

Scenario 3: Finding the VAT rate. A product costs €100 net and €120 gross. VAT = €120 − €100 = €20. VAT Rate = (€20 ÷ €100) × 100 = 20%. Try this live with the "Find VAT Rate" mode above.

Scenario 4: Multiple items. You buy 3 items at €50 each (excluding VAT). VAT is 20%. Subtotal = 3 × €50 = €150. VAT = €150 × 20% = €30. Total = €150 + €30 = €180. Build this live in the printable invoice below.

Scenario 5: VAT included vs excluded. A restaurant bill is €120 including 20% VAT. Net = €120 ÷ 1.20 = €100. VAT = €120 − €100 = €20.

Practice Problems

Problem 1: A product costs €80 before VAT. VAT is 23%. What is the gross price? Solution: VAT = €80 × 0.23 = €18.40. Gross = €80 + €18.40 = €98.40.

Problem 2: You paid €120 for a product including 20% VAT. What was the net price? Solution: Net = €120 ÷ 1.20 = €100.

Problem 3: A product costs €100 net and €123 gross. What is the VAT rate? Solution: VAT = €123 − €100 = €23. VAT Rate = (€23 ÷ €100) × 100 = 23%.

Problem 4: You buy 4 items at £25 each (excluding VAT). VAT is 20%. What's the total? Solution: Subtotal = 4 × £25 = £100. VAT = £100 × 20% = £20. Total = £100 + £20 = £120.

Problem 5: A restaurant bill is £72 including 20% VAT. How much is the VAT? Solution: Net = £72 ÷ 1.20 = £60. VAT = £72 − £60 = £12.

Answers: 1) €98.40 — 2) €100 — 3) 23% — 4) £120 — 5) £12

Common VAT Mistakes

Using the wrong rate. Mistake: applying the standard rate to reduced-rate items. Fix: check the correct rate for the product or service.
Confusing net and gross. Mistake: using the gross price when the net price is needed. Fix: always confirm whether prices include VAT.
Forgetting to add VAT to quotes. Mistake: quoting net prices without mentioning VAT. Fix: B2B quotes may be net; B2C quotes usually include VAT.
Incorrect reverse calculation. Mistake: dividing by the VAT rate instead of 1 + VAT rate. Fix: Net = Gross ÷ (1 + VAT Rate).
Not claiming refunds. Mistake: not claiming VAT refunds when eligible. Fix: check eligibility for business and tourist refunds.
Confusing VAT with sales tax. Mistake: treating VAT like sales tax. Fix: VAT applies at all stages; sales tax only at the final sale.
Not registering for VAT. Mistake: not registering when the threshold is met. Fix: check the threshold in your country.
Incorrect VAT on invoices. Mistake: wrong VAT rate shown on invoices. Fix: always double-check invoices — try the printable invoice mockup below.

Frequently Asked Questions

What is a VAT calculator?+

A VAT calculator helps you add or remove VAT from a price. Enter the net price and VAT rate to get the gross price, or enter the gross price to find the net price.

How do you work out VAT?+

To work out VAT, multiply the net price by the VAT rate. For example, €100 × 20% = €20 VAT.

How do I add VAT to a price?+

Gross = Net × (1 + VAT Rate). Example: €100 × 1.20 = €120.

How do I remove VAT from a price?+

Net = Gross ÷ (1 + VAT Rate). Example: €120 ÷ 1.20 = €100.

What is the VAT rate in the UK?+

The UK standard VAT rate is 20%. The reduced rate is 5% and the zero rate is 0%.

What is the minimum purchase for a VAT refund?+

It varies by country: Germany €50, France €100, Italy €155, Spain €90, UK £30.

How do I figure out VAT on a receipt?+

If you know the total (including VAT) and the VAT rate, use: Net = Total ÷ (1 + Rate). Then VAT = Total − Net. Use the "Find VAT Rate" mode above if you know both prices but not the rate.

What is the VAT registration threshold in the UK?+

The UK VAT registration threshold is £85,000 annual turnover.

Is this VAT calculator free?+

Yes — completely free with no registration required.

What is the difference between standard rate, reduced rate, and zero-rated VAT?+

The standard rate applies to the vast majority of goods and services in a country. A reduced rate applies to essential items like residential energy, domestic transport, or books to make them more affordable. Zero-rated items (like basic foods, international flights, or exports) have a 0% VAT rate, meaning no VAT is charged, but businesses can still reclaim all Input VAT incurred. Exempt items (like education, healthcare, or financial services) are completely outside the VAT system; no tax is charged, but businesses cannot reclaim Input VAT.

What is a reverse charge mechanism?+

A reverse charge mechanism shifts the liability to report and pay VAT from the seller to the buyer. This typically occurs in cross-border B2B transactions (especially digital services in the EU/UK). Instead of the foreign supplier registering for VAT in the buyer's country, the buyer reports both the Output VAT (as a sale to themselves) and the Input VAT (as a purchase) on their local tax return, resulting in a net-zero tax effect.

How does VAT differ from retail sales tax?+

Retail sales tax is a single-stage tax levied only at the final point of sale to the consumer. If businesses purchase items for resale, they must present exemption certificates to avoid paying sales tax. VAT is a multi-stage tax collected at every step of production. Businesses pay VAT on inputs and charge VAT on outputs, reporting the net difference to the tax authority. This reduces tax evasion because transactions are documented at every step of the supply chain.

Can tourists reclaim VAT paid on shopping abroad?+

Yes, many countries allow non-resident tourists to claim a refund on VAT paid for tangible goods purchased during their visit, provided the goods are exported unused in their luggage. Tourists must obtain a VAT refund form at the store, get it stamped by customs at the airport when leaving the country, and submit it to a refund provider (minus admin fees). Minimum purchase amounts apply and vary by country.

What happens if a business is not registered for VAT?+

If a business's taxable turnover falls below the government's mandatory registration threshold (e.g., £85,000 in the UK), they are not required to register. Non-registered businesses do not charge VAT on their sales, but they also cannot reclaim any Input VAT they pay on their business expenses. Once turnover crosses the threshold, registration is legally mandatory.

Is VAT the same as GST?+

VAT and GST are often used interchangeably, but they have different implementations. GST is generally a single tax on the supply of goods and services (used in Australia, Canada, New Zealand, Singapore, and India), while VAT is a tax on final consumption collected across multiple stages (used across the EU, UK, and many other countries).

How the calculation works

1Choose Add VAT, Remove VAT, or Find VAT Rate.

2Enter the numerical base amount you want to analyze (or both net and gross for Find VAT Rate).

3Select a country from the predefined dropdown to load its standard or reduced VAT rate, or check the custom rate toggle to enter any rate.

4Review the results showing the isolated Net, VAT, and Gross totals.

How to understand and use this calculator

Quick Answer

What is VAT? Value-Added Tax (VAT) is a consumption tax applied to goods and services at each stage of production. The final consumer bears the full tax burden.

Key formulas:

Add VAT: Gross = Net × (1 + VAT Rate)
Remove VAT: Net = Gross ÷ (1 + VAT Rate)
VAT Amount: VAT = Gross − Net

Simple example: Net price = €100, VAT rate = 20%.

VAT amount: €100 × 20% = €20
Gross price: €100 + €20 = €120

Quick reference:

20% VAT on €100 → €20 VAT, €120 gross
Remove 20% VAT from €120 → €100 net, €20 VAT
23% VAT on €100 → €23 VAT, €123 gross

Use the VAT Calculator

To use the calculator with VAT:

1. Enter the net price (price before VAT), or the gross price if removing VAT.

2. Enter the VAT rate — pick a country preset (with reduced rate where available) or a custom rate.

3. Select Add VAT, Remove VAT, or Find VAT Rate.

4. Review the VAT amount, gross price, and step-by-step work.

Example input (Add VAT): Net Price = €100.00, VAT Rate = 20%.

Output:

VAT Amount = €20.00
Gross Price = €120.00
Step-by-step work: €100 × 20% = €20 → €100 + €20 = €120

Example input (Remove VAT): Gross Price = €120.00, VAT Rate = 20%.

Output:

Net Price = €100.00
VAT Amount = €20.00
Step-by-step work: €120 ÷ 1.20 = €100

Introduction to Value-Added Tax (VAT) and Global Taxation

The Mathematical Formulations: Adding and Removing VAT

To add VAT to a net amount, the absolute tax is computed by multiplying the net figure by the rate percentage divided by 100:

T = N × ( V/100 )

The final gross amount is the simple summation of the net value and the tax amount, which is represented by:

G = N + T = N × ( 1 + V/100 )

N = G/(1 + V/100) = (G × 100)/(100 + V)

Once the net amount is isolated, the VAT amount component can be found by subtracting the net from the gross, or by applying the isolated rate ratio directly:

T = G - N = G × ( V/(100 + V) )

Step-by-Step Manual Calculation Examples

To ground these theoretical algebraic concepts in day-to-day business accounting, let us work through two detailed, step-by-step practical examples using common real-world variables.

Step 1: Identify the variables. Here, Net Amount N = 2,500 and VAT Rate V = 20 .

Step 2: Calculate the absolute tax component using the tax addition formula:

T = 2,500 × ( 20/100 ) = 2,500 × 0.20 = 500

Step 3: Add the tax amount to the net amount to determine the final gross invoice price:

G = 2,500 + 500 = 3,000

The firm will charge a gross price of £3,000 to the client, recording £2,500 as operating revenue and holding £500 in a liability account to be paid to HM Revenue Customs (HMRC).

Step 1: Identify the variables. Gross Amount G = 127,000 and VAT Rate V = 27 .

Step 2: Calculate the net amount by dividing the gross price by 1 + V/100 :

N = 127,000/(1 + 0.27) = 127,000/1.27 = 100,000 HUF

Step 3: Subtract the net amount from the gross price to isolate the tax portion:

T = 127,000 - 100,000 = 27,000 HUF

The retailer received 100,000 HUF for the product, and 27,000 HUF was collected on behalf of the Hungarian National Tax and Customs Administration.

VAT vs Sales Tax — What's the Difference?

Feature comparison:

Type: VAT — multi-stage tax. Sales tax — single-stage tax.
When charged: VAT — every stage of production. Sales tax — only at final sale.
Who bears it: Both — the final consumer.
Visibility: VAT — less visible (often included in the sticker price). Sales tax — very visible on the receipt.
Administrative cost: VAT — higher. Sales tax — lower.
Where used: VAT — Europe, Asia, Australia, Canada (GST). Sales tax — United States (state level).

Key takeaway: both result in the same total tax, but VAT is collected in stages while sales tax is only collected at the final sale. Need US sales tax instead? Try the Sales Tax Calculator.

VAT vs GST — What's the Difference?

Feature comparison:

Definition: VAT — tax on final consumption. GST — tax on the supply of goods/services.
Linked to: VAT — the sales moment. GST — the point of supply.
Operation: VAT — offline, summary-based. GST — online, transaction-based.
Responsibility: VAT — seller collects the tax. GST — purchaser records the tax.
Double taxation: VAT — can occur on excisable goods. GST — generally subsumed, avoiding double taxation.
Where used: VAT — EU, UK, and many other countries. GST — Australia, Canada, New Zealand, Singapore, India.

Key insight: VAT and GST are often used interchangeably, but they have different implementations. GST is generally simpler and more efficient.

How to Add VAT (Net to Gross)

Formula: Gross Price = Net Price × (1 + VAT Rate)

Step-by-step example: Net price = €80, VAT rate = 20%.

Step 1: Convert to decimal: 20% ÷ 100 = 0.20.

Step 2: Add 1: 1 + 0.20 = 1.20.

Step 3: Multiply: Gross = €80 × 1.20 = €96.

Answer: Gross price = €96

More examples:

Net €100 at 20% → Gross €120, VAT €20
Net €50 at 23% → Gross €61.50, VAT €11.50
Net £75 at 20% → Gross £90, VAT £15
Net €200 at 19% → Gross €238, VAT €38

How to Remove VAT (Gross to Net)

Formula: Net Price = Gross Price ÷ (1 + VAT Rate)

Step-by-step example: Gross price = £120, VAT rate = 20%.

Step 1: Convert to decimal and add 1: 1 + 0.20 = 1.20.

Step 2: Divide: Net = £120 ÷ 1.20 = £100.

Answer: Net price = £100

More examples:

Gross €120 at 20% → Net €100, VAT €20
Gross €61.50 at 23% → Net €50, VAT €11.50
Gross £90 at 20% → Net £75, VAT £15
Gross €238 at 19% → Net €200, VAT €38

How to Figure Out VAT — Different Scenarios

Scenario 1: Adding VAT. A product costs €80 before VAT. VAT is 23%. VAT = €80 × 23% = €18.40. Gross = €80 + €18.40 = €98.40.

Scenario 2: Removing VAT. You paid €120 for a product including 20% VAT. Net = €120 ÷ 1.20 = €100.

Scenario 5: VAT included vs excluded. A restaurant bill is €120 including 20% VAT. Net = €120 ÷ 1.20 = €100. VAT = €120 − €100 = €20.

Practice Problems

Problem 1: A product costs €80 before VAT. VAT is 23%. What is the gross price? Solution: VAT = €80 × 0.23 = €18.40. Gross = €80 + €18.40 = €98.40.

Problem 2: You paid €120 for a product including 20% VAT. What was the net price? Solution: Net = €120 ÷ 1.20 = €100.

Problem 3: A product costs €100 net and €123 gross. What is the VAT rate? Solution: VAT = €123 − €100 = €23. VAT Rate = (€23 ÷ €100) × 100 = 23%.

Problem 4: You buy 4 items at £25 each (excluding VAT). VAT is 20%. What's the total? Solution: Subtotal = 4 × £25 = £100. VAT = £100 × 20% = £20. Total = £100 + £20 = £120.

Problem 5: A restaurant bill is £72 including 20% VAT. How much is the VAT? Solution: Net = £72 ÷ 1.20 = £60. VAT = £72 − £60 = £12.

Answers: 1) €98.40 — 2) €100 — 3) 23% — 4) £120 — 5) £12

Common VAT Mistakes

Using the wrong rate. Mistake: applying the standard rate to reduced-rate items. Fix: check the correct rate for the product or service.
Confusing net and gross. Mistake: using the gross price when the net price is needed. Fix: always confirm whether prices include VAT.
Forgetting to add VAT to quotes. Mistake: quoting net prices without mentioning VAT. Fix: B2B quotes may be net; B2C quotes usually include VAT.
Incorrect reverse calculation. Mistake: dividing by the VAT rate instead of 1 + VAT rate. Fix: Net = Gross ÷ (1 + VAT Rate).
Not claiming refunds. Mistake: not claiming VAT refunds when eligible. Fix: check eligibility for business and tourist refunds.
Confusing VAT with sales tax. Mistake: treating VAT like sales tax. Fix: VAT applies at all stages; sales tax only at the final sale.
Not registering for VAT. Mistake: not registering when the threshold is met. Fix: check the threshold in your country.
Incorrect VAT on invoices. Mistake: wrong VAT rate shown on invoices. Fix: always double-check invoices — try the printable invoice mockup below.
