Break-Even Calculator
Enter your fixed costs, unit price, and variable cost to estimate the minimum whole units you need to sell to break even.
How to use this break-even calculator
- Enter fixed costs
Type your total fixed costs — rent, salaries, insurance, and any other expenses that stay constant regardless of sales volume.
- Set the selling price
Enter the price per unit you charge or plan to charge customers.
- Add the variable cost
Enter the variable cost per unit — materials, packaging, shipping, or any cost that scales with each unit sold.
- Read the break-even result
The calculator shows the minimum whole units you need to sell and the corresponding break-even revenue.
- Adjust and compare
Try different price points or cost assumptions to see how each change moves the break-even target up or down.
How this break-even calculator works
The break-even point is where total revenue equals total costs. This calculator divides fixed costs by the contribution margin (price minus variable cost) to find how many units you must sell to cover all expenses.
Break-even units = fixed costs / (price per unit − variable cost per unit) With $50,000 in fixed costs, a $50 selling price, and $20 variable cost: contribution margin = $30, break-even = 1,667 units ($83,350 revenue).
Starting with the same $50,000 in fixed costs and $20 variable cost, raising the selling price above $50 widens the contribution margin beyond $30 per unit and lowers the break-even point below 1,667 units. Even a modest price increase can meaningfully reduce the number of sales needed to cover costs, making pricing strategy one of the fastest levers for improving profitability.
Keeping the $50 selling price and $20 variable cost unchanged but cutting fixed costs below $50,000 — for example by renegotiating rent or eliminating an underused subscription — reduces the break-even point proportionally. Lowering fixed costs is often the safest path to profitability because it does not depend on selling more units or convincing customers to pay a higher price.
- ✓ All units sell at the same price.
- ✓ Variable cost per unit is constant.
- ✓ Fixed costs do not change within the relevant range.
- ✓ Break-even units are rounded up to the next whole unit because you cannot usually sell a fraction of a unit in practical planning.
- Real businesses have mixed cost structures. This is a simplified model for planning.
- The result shows the minimum whole-unit sales target needed to cover costs, not an exact fractional threshold.
What is break-even analysis?
Break-even analysis tells you exactly how many units you must sell before your business starts turning a profit. Below the break-even point every sale still leaves you in the red because total revenue has not yet covered fixed costs. Above it, each additional unit sold contributes directly to profit. The key figure behind the calculation is the contribution margin — the difference between the selling price and the variable cost of one unit. A higher contribution margin means fewer sales are needed to cover fixed costs, while a slim margin requires much higher volume. Break-even analysis is one of the first financial tests applied to a new product, service, or business idea because it answers a fundamental question: is the required sales volume realistic given your market size and capacity? It is also useful for existing businesses evaluating price changes, cost-reduction initiatives, or expansion plans.
How to reduce your break-even point
There are three main levers for lowering the break-even point: raise the selling price, reduce variable costs, or cut fixed costs. Raising the price widens the contribution margin per unit so fewer sales are needed, but price sensitivity may limit how far you can go. Reducing variable costs — negotiating better supplier rates, improving production efficiency, or switching materials — achieves the same margin improvement without asking customers to pay more. Cutting fixed costs such as downsizing office space, renegotiating leases, or eliminating underused subscriptions lowers the total hurdle that sales must clear. In practice, most businesses combine all three. Even small improvements compound: a modest price increase paired with a small cut in material cost can dramatically lower the break-even volume. Running the numbers for several scenarios helps identify which lever has the greatest practical impact given your specific cost structure.
