How to use Break-Even Calculator

What the tool does, how to run it, and what to expect from the result.

How to calculate a break-even point

Enter your fixed costs for the period, the price you charge per unit, and what each unit costs you to make or deliver. The tool subtracts to find the contribution margin and divides the fixed costs by it.

The answer is the number of units at which revenue exactly equals total cost. Below it you are losing money, above it every additional unit contributes its full margin to profit.

  • Enter your period fixed costs in the Fixed costs field. It starts at 5000. Rent, salaries, and software belong here.
  • Enter your price in the Price per unit field. It starts at 40.
  • Enter your per-unit cost in the Variable cost per unit field. It starts at 15. Materials, shipping, and payment fees belong here.
  • Read Break-even units, Break-even revenue, and the Contribution margin per unit.
  • To solve for a profit target rather than zero, add the target to the fixed-costs field before you calculate.
Tips

Getting a better result out of Break-Even Calculator

Specific settings and thresholds, not general advice.

  • Break-even units are fixed costs / (price - variable cost). The defaults, 5000 of fixed costs against a 25 contribution margin, break even at 200 units and 8000 of revenue.
  • Contribution margin is the lever that matters. Raising the price 10% from 40 to 44 lifts the margin from 25 to 29 and drops break-even from 200 units to 173, a 14% improvement from a 10% price move.
  • If the price is at or below the variable cost, the tool shows n/a rather than a number. That is correct: no volume ever covers fixed costs when every unit loses money.
  • Units are rounded up with a ceiling, because you cannot sell a fraction of a unit. The revenue line is computed on the exact fractional count, so the two will not multiply out precisely.
  • Everything is per period, and the period is whatever your fixed-cost figure covers. Enter monthly fixed costs and you get monthly break-even units, enter annual and you get annual.
Limits

What Break-Even Calculator does not do

The honest boundary, so you do not lose time finding it yourself.

  • One product at one price. No product mix and no blended contribution margin.
  • Fixed costs are assumed flat at every volume. No step-fixed costs as you add capacity.
  • No cash-flow timing, no ramp, no time-to-break-even in months.
  • No target-profit mode. It solves for zero profit, not for the volume that hits a profit goal.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is the break-even calculator free?

Yes. It is completely free to use, with no signup, no account, and no paywall.

How accurate are the results?

The calculator uses the standard formulas for this kind of math, but real-world results can differ once fees, rounding, rate changes, and provider-specific rules come into play. Treat the output as a planning estimate, not a quote.

Does it stay local?

Yes. The numbers you enter are processed entirely in your browser and never leave your device.

What counts as a fixed cost and what counts as variable?

Fixed costs do not move with volume: rent, salaries, software, insurance. Variable costs are incurred per unit sold: materials, packaging, shipping, payment fees. Misclassifying a per-unit cost as fixed makes break-even look far closer than it is.

Why does it show n/a?

Because your price is at or below your variable cost, so the contribution margin is zero or negative. Every sale then loses money and no volume ever recovers the fixed costs. The fix is a higher price or a lower unit cost, not more sales.

Is the break-even figure monthly or annual?

Whatever period your fixed-cost figure covers. The tool has no time input. If you enter 5000 of monthly fixed costs, the 200 units are per month.

How many units do I need for a target profit rather than break-even?

Add the profit target to your fixed costs before entering them. To make 2000 of profit on the defaults, enter 7000 instead of 5000, which requires 280 units rather than 200.

Can it handle several products at once?

No. It takes one price and one variable cost. For a mix, compute a weighted average contribution margin across your products by sales share and enter that as a single blended figure.
