Formula

Break-even units

Break-even units = fixed costs / (price per unit - variable cost per unit)

The calculator divides fixed costs by contribution margin to estimate how many units must be sold before profit begins.

Step by step

How the calculation works

1Calculate contribution margin per unit.
2Divide fixed costs by contribution margin.
3Round up because partial units cannot usually be sold.
4Multiply units by price to estimate break-even revenue.

Example

Example break-even point

$50,000 fixed costs with a $45 contribution per unit requires about 1,112 units to break even.

Break-Even Point: The Operational Milestone

The break-even point is the operational milestone where a business's total revenues exactly equal its total costs. At this point, the business makes zero profit but incurs zero losses. Identifying this milestone is critical for evaluating new business viability, pricing strategies, and marketing budgets.

To run a break-even calculation, you must divide your expenses into fixed costs (rent, insurance, salaries that do not change with production volume) and variable costs (raw materials, packaging, transaction fees that increase with every unit sold). Using a break-even calculator alongside the profit margin calculator and the operating margin calculator helps set sustainable sales volume targets.

The Break-Even Formulas

To calculate the break-even point in units and revenue, apply these formulas:

$$\text{Contribution Margin} = \text{Price per Unit} - \text{Variable Cost per Unit}$$

$$\text{Break-Even Units} = \frac{\text{Fixed Costs}}{\text{Contribution Margin}}$$

$$\text{Break-Even Revenue} = \text{Break-Even Units} \times \text{Price per Unit}$$

$$\text{Contribution Margin Ratio} = \left( \frac{\text{Contribution Margin}}{\text{Price per Unit}} \right) \times 100$$

For example, if your fixed costs are $10,000 per month, your selling price is $50, and your variable cost is $30, the contribution margin is $20. Your break-even units are $10,000 / 20 = 500$ units, and break-even revenue is $500 \times 50 = \$25,000$.

Break-Even in Service and SaaS Industries

While product businesses calculate break-even in physical units, service and software companies often look at billable hours or customer acquisitions. Combining break-even analysis with the freelance rate calculator helps independent contractors determine their minimum billable hours, while SaaS teams use the SaaS burn rate and runway calculator to find the monthly subscription volume needed to cover software engineering overhead.

Fixed Costs

Expenses that do not change with the volume of goods or services produced.

Variable Costs

Expenses that vary directly with the level of output or sales.

Contribution Margin

The selling price of a product minus its variable costs, representing capital available to cover fixed overhead.

Frequently Asked Questions

What is the break-even point?+

The break-even point is the sales volume (in units or revenue) where total revenue equals total costs, resulting in zero profit and zero loss.

What are fixed costs?+

Fixed costs are business expenses that remain constant regardless of sales volume, such as rent, salaries, insurance, and equipment leases.

What are variable costs?+

Variable costs are expenses that rise and fall directly with production or sales volume, such as raw materials, packaging, shipping, and credit card fees.

How do you calculate contribution margin?+

Contribution margin is the selling price per unit minus the variable cost per unit. It represents the amount of money each sale contributes to covering fixed costs.

How does raising prices affect the break-even point?+

Raising prices increases the contribution margin per unit, which decreases the number of units you need to sell to break even.

What happens if variable costs increase?+

If variable costs increase, the contribution margin shrinks, meaning you must sell more units to cover your fixed expenses and break even.

What is a contribution margin ratio?+

The contribution margin ratio is the contribution margin divided by the selling price, showing the percentage of each sales dollar available to cover fixed costs.

Can a business break even but have negative cash flow?+

Yes. If a business has significant debt payments, accounts receivable delays, or capital expenditures that do not appear on the income statement, it may experience cash flow issues despite technically breaking even.

Why is break-even analysis important for startups?+

It defines the minimum viable sales target needed to survive, helping founders budget seed capital, set prices, and pitch realistic forecasts to investors.

How does automation affect break-even?+

Investing in automation typically increases fixed costs (buying machines or software) but decreases variable costs (lower labor per unit), which raises the initial break-even point but improves profitability at higher sales volumes.
