About the Break-Even Analysis Calculator
The Break-Even Analysis Calculator shows exactly how many units you need to sell — or how much revenue you need to generate — to cover all your costs. Below that point, you're losing money. Above it, every additional sale is profit.
This is one of the most critical tools for any business, from a new startup to an established manufacturer. Enter your fixed costs, price per unit, and variable cost per unit to see your break-even point in units and dollars.
The calculator also shows your margin of safety (how far above break-even your current sales are), the contribution margin per unit, and a detailed table showing profit/loss at various sales volumes. Understanding where break-even falls is essential for launch decisions, pricing strategy, and scaling plans. Entrepreneurs who know their break-even point can set realistic sales targets, evaluate whether adding fixed costs like new hires or equipment is justified, and quickly identify when market conditions threaten profitability.
When This Page Helps
Every business decision — pricing, hiring, expansion, marketing spend — should consider the break-even point. This calculator helps you test scenarios quickly: what if you raise prices 10%? Hire a new employee (increasing fixed costs)? Reduce variable costs through bulk purchasing? See how the break-even point changes under each scenario. With this insight, every pricing or cost decision becomes a data-driven choice rather than a guess.
How to Use the Inputs
- Enter your total fixed costs (rent, salaries, insurance, etc.).
- Enter the selling price per unit.
- Enter the variable cost per unit (materials, labor, shipping).
- Optionally enter your current sales volume.
- View the break-even point in units and revenue.
- Check the margin of safety if above break-even.
- Explore the profit/loss table at different volumes.
Formula used
Contribution Margin = Price − Variable Cost
Break-Even Units = Fixed Costs / Contribution Margin
Break-Even Revenue = Break-Even Units × Price
Margin of Safety = (Current Sales − Break-Even) / Current Sales × 100Example Calculation
Result: Break-even: 3,334 units ($83,350 revenue)
With $50,000 fixed costs, $25 price, and $10 variable cost, the contribution margin is $15/unit. Break-even = $50,000 / $15 = 3,334 units. At 5,000 current sales, margin of safety is 33.3% — a healthy buffer above break-even.
Tips & Best Practices
- A low margin of safety (<20%) means your business is vulnerable to sales dips.
- Increasing price has a bigger impact on break-even than reducing variable costs by the same amount.
- Include ALL fixed costs: rent, salaries, insurance, loan payments, subscriptions, depreciation.
- Variable costs should include materials, direct labor, shipping, commissions, and payment processing.
- Run this analysis for each product or service line separately for clearer insights.
- Revisit break-even quarterly as costs and prices change.
Types of Break-Even Analysis
Unit break-even shows how many units must be sold. Revenue break-even shows the total dollar amount needed. Time-to-break-even shows how long it takes at a given sales rate. All three perspectives are valuable for different business decisions.
Common Break-Even Mistakes
The biggest mistake is underestimating fixed costs. Don't forget depreciation, software subscriptions, professional services, and owner's salary. Another common error is ignoring step costs — fixed costs that jump at certain volumes (e.g., needing a second warehouse at 10,000 units).
Break-Even and Pricing Strategy
Break-even analysis is the foundation of cost-plus pricing. Knowing your break-even point tells you the minimum viable price. From there, add your target profit margin. Many businesses discover they're pricing too low only after running this analysis.

Methodology
This worksheet applies the standard break-even formula: fixed costs divided by contribution margin per unit. It then converts the result into revenue and margin-of-safety views for planning.
It is designed for small-business planning and scenario analysis, not a guarantee of profitability or an accounting close.

Frequently Asked Questions
The break-even point is when total revenue exactly equals total costs (fixed + variable). Below this point, you're operating at a loss. Above it, you're generating profit. It's measured in units sold or revenue dollars.
Fixed costs stay the same regardless of sales volume: rent, salaries, insurance, loan payments. Variable costs change with each unit sold: materials, direct labor, shipping, commissions. Understanding this split is essential for break-even analysis.
A margin of safety above 25% is generally considered healthy. It means sales can drop 25% before you start losing money. Service businesses may be comfortable with 15-20%, while manufacturing businesses with high fixed costs need 30%+.
Raising prices dramatically lowers break-even. A 10% price increase on a $25 product (to $27.50) with $10 variable cost changes contribution margin from $15 to $17.50 — reducing break-even units by 14%. Price is the most powerful lever.
Yes. For services, the "unit" is an hour, session, project, or client. Fixed costs include overhead, and variable costs include time, materials, and any per-service expenses. The math is identical.
For multiple products, use a weighted average contribution margin based on your sales mix. Calculate the weighted average, then divide fixed costs by that figure. Alternatively, run separate analyses for each product line.
