Break Even Point Calculator
Solve break even point problems step-by-step with our free calculator. See formulas, worked examples, and clear explanations.
Formula
Break-Even Units = Fixed Costs / (Price per Unit - Variable Cost per Unit)
The break-even quantity equals total fixed costs divided by the contribution margin (price minus variable cost per unit). Break-even revenue = break-even units multiplied by the price. The contribution margin ratio shows what percentage of each dollar of revenue covers fixed costs and profit.
Worked Examples
Example 1: Coffee Shop Break-Even
Problem: A coffee shop has $8,000/month fixed costs (rent, salaries). Each coffee costs $1.50 in ingredients (variable cost) and sells for $5. How many coffees must they sell to break even?
Solution: Contribution margin: $5.00 - $1.50 = $3.50\nBreak-even units: $8,000 / $3.50 = 2,286 coffees\nBreak-even revenue: 2,286 × $5 = $11,430\nThat is about 76 coffees per day (30-day month).
Result: 2,286 coffees/month | $11,430 revenue to break even
Example 2: SaaS Product Launch
Problem: Monthly fixed costs: $25,000 (infrastructure, team). Variable cost per user: $3/month. Subscription price: $29/month.
Solution: Contribution margin: $29 - $3 = $26\nBreak-even subscribers: $25,000 / $26 = 962\nBreak-even MRR: 962 × $29 = $27,898\nContribution margin ratio: $26/$29 = 89.7%
Result: 962 subscribers needed | $27,898 MRR to break even
Frequently Asked Questions
What is the break-even point?
The break-even point is the number of units you need to sell (or the revenue you need to generate) to cover all your costs — both fixed and variable. At break-even, total revenue equals total costs, and profit is zero. Selling above break-even generates profit; below it, you incur losses. It is a fundamental concept in business planning, pricing strategy, and financial analysis.
Can I use the results for professional or academic purposes?
You may use the results for reference and educational purposes. For professional reports, academic papers, or critical decisions, we recommend verifying outputs against peer-reviewed sources or consulting a qualified expert in the relevant field.
How do I interpret the result?
Results are displayed with a label and unit to help you understand the output. Many calculators include a short explanation or classification below the result (for example, a BMI category or risk level). Refer to the worked examples section on this page for real-world context.
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
