Break-Even Calculator

The break-even point (BEP) is the number of units you need to sell, or the revenue you need to generate, to cover all your costs. At this point you are not making a profit, but you are not losing money either.

The formula:

• BEP (units) = Fixed Costs ÷ (Selling Price − Variable Cost per Unit)
• BEP (revenue) = BEP (units) × Selling Price

Simple example:

Quick reference: Break-even = Fixed Costs ÷ Profit per Unit. Above BEP = profit. Below BEP = loss.

To use the break-even point calculator:

• Choose Business (units & revenue)
• Enter your fixed costs (rent, utilities, salaries)
• Enter your selling price per unit
• Enter your variable cost per unit
• Review the break-even point in units and revenue, the profit per unit, and the step-by-step work. The results update as you type.

Another example (e-commerce):

The break-even point (BEP) is the point at which your total revenue equals your total costs. At this point you have covered all your expenses, you are not making a profit yet, and you are not losing money either.

Why it matters:

• Tells you how many units you need to sell to cover costs
• Helps you set sales targets
• Guides pricing decisions
• Shows whether a business idea is viable

Break-even analysis is useful for any business, from a one-person shop to a product launch inside a large company:

Break-Even Point (Units) = Fixed Costs ÷ (Selling Price − Variable Cost per Unit)

Break-Even Point (Revenue) = Break-Even Point (Units) × Selling Price

Where:

• Fixed costs = costs that do not change with volume
• Selling price = price per unit
• Variable cost = cost per unit that changes with volume

The logic: each unit sold contributes (selling price − variable cost) toward covering fixed costs. Once enough units are sold to cover fixed costs, you break even, and every unit after that adds profit.

Learning how to calculate BEP is simple with these steps:

Step 1: Identify fixed costs. Example: $2,700 (rent, utilities, salaries).

Step 2: Identify the selling price per unit. Example: $45.

Step 3: Identify the variable cost per unit. Example: $30.

Step 4: Calculate profit per unit. Selling price − variable cost = $45 − $30 = $15.

Step 5: Calculate BEP in units. Fixed costs ÷ profit per unit = $2,700 ÷ $15 = 180 units.

Step 6: Calculate BEP in revenue. BEP units × selling price = 180 × $45 = $8,100.

Answer: you need to sell 180 units, or $8,100 in revenue, to break even.

Formula: BEP (units) = Fixed Costs ÷ (Selling Price − Variable Cost). If the answer is a fraction, round up: you cannot sell part of a unit, and rounding down would leave you just short of break-even.

Formula: BEP (revenue) = BEP (units) × Selling Price.

Alternative formula (useful when you do not sell identical units): BEP (revenue) = Fixed Costs ÷ (1 − Variable Cost ÷ Selling Price). The bottom of that fraction is the contribution margin ratio.

• BEP (revenue) = $2,700 ÷ (1 − $30 ÷ $45)
• BEP (revenue) = $2,700 ÷ (1 − 2/3)
• BEP (revenue) = $2,700 ÷ 1/3
• BEP (revenue) = $8,100

Keep the ratio as a fraction (1/3) rather than rounding it to 0.333. Rounded, $2,700 ÷ 0.333 gives $8,108, which is $8 off.

Switch the calculator to Social Security claiming age to use it as a Social Security break-even calculator for retirement planning.

What is Social Security break-even?

• Your monthly benefit is larger the longer you wait to claim, up to age 70
• The break-even age is the age at which the total you would have collected by waiting catches up with the total from claiming earlier
• If you live past the break-even age, delaying pays more in total
• If you do not, claiming earlier pays more in total

Key factors: your full retirement age (FRA, which is 67 for anyone born in 1960 or later), the ages you are comparing, the monthly benefit at each age, and your life expectancy.

Typical Social Security break-even ages (FRA of 67, benefits of 70% at 62 and 124% at 70 under SSA's early and delayed claiming rules; ignores cost-of-living adjustments, taxes, and investment returns):

Learning how to calculate the break-even point for Social Security takes four steps.

Step 1: Identify your benefit amounts from your SSA statement. Example: $1,500 a month at 62, $2,100 a month at 67, $2,600 a month at 70.

Step 2: Calculate the difference. Claiming at 70 instead of 62: $2,600 − $1,500 = $1,100 a month more, or $13,200 a year.

Step 3: Calculate the head start from claiming early. From 62 to 70 the early claimer receives $1,500 × 12 × 8 = $144,000, while the person who waits receives nothing.

Step 4: Calculate the break-even age.

• Break-even age = 70 + ($144,000 ÷ ($2,600 × 12 − $1,500 × 12))
• Break-even age = 70 + ($144,000 ÷ $13,200)
• Break-even age = 70 + 10.9 years
• Break-even age = 80.9

Interpretation: if you live past about 81, claiming at 70 pays more in total. If you do not, claiming at 62 pays more. Your health, other income, and a spouse's survivor benefit also belong in the decision.

Below the results, the calculator draws a break-even chart of your profit or loss at 0%, 50%, 100%, 150%, and 200% of break-even volume. The line crosses zero at the break-even point. In Social Security mode it plots the lifetime advantage of waiting by age instead.

What a classic break-even chart shows:

• X-axis: number of units sold
• Y-axis: revenue and costs
• Total revenue line: starts at $0 and rises with each unit
• Total cost line: starts at the fixed costs and rises with variable costs
• Break-even point: where the two lines intersect
• Profit zone: to the right of the break-even point, where revenue is above cost
• Loss zone: to the left of the break-even point, where cost is above revenue

Key insight: break-even is about operating profitability. Payback time is about recovering an initial investment. For a payback period and return on a large purchase, use the CapEx ROI calculator or the ROI calculator.

The coffee shop figure is 2,857.14 rounded up: at 2,857 coffees the shop is still 50 cents short.

Problem 1: A business has fixed costs of $5,000, a selling price of $25, and a variable cost of $10. What is the break-even point in units?

Solution: profit per unit = $25 − $10 = $15. BEP = $5,000 ÷ $15 = 333.33, rounded up to 334 units.

Problem 2: Using Problem 1, what is the break-even point in revenue?

Solution: BEP (revenue) = 334 × $25 = $8,350.

Problem 3: A company has fixed costs of $10,000, a selling price of $100, and a variable cost of $60. What is the break-even point?

Solution: profit per unit = $100 − $60 = $40. BEP = $10,000 ÷ $40 = 250 units.

Problem 4: A service business has fixed costs of $4,000, a selling price of $200, and a variable cost of $80. How many clients are needed to break even?

Solution: profit per client = $200 − $80 = $120. BEP = $4,000 ÷ $120 = 33.33, rounded up to 34 clients.

Problem 5: A Social Security recipient compares claiming at 62 ($1,500 a month) with claiming at 70 ($2,600 a month). What is the break-even age?

Solution: benefits collected from 62 to 70 = $1,500 × 12 × 8 = $144,000. Extra per year from waiting = $1,100 × 12 = $13,200. Break-even = 70 + ($144,000 ÷ $13,200) = 70 + 10.9 = 80.9 years.

Answers: 1. 334 units · 2. $8,350 · 3. 250 units · 4. 34 clients · 5. 80.9 years
