How many units you have to sell before fixed costs are covered and the business starts making money.

Fixed costsPrice per unitVariable cost per unit

Contribution per unit is the number that mattersOnly the gap between price and variable cost pays down fixed costs. If that gap is zero or negative, no volume ever breaks even - selling more simply loses more, and this tool says so rather than quoting a large number.

The release tests verify that $1,000 of fixed cost with a $10 price and $7 variable cost rounds up to 334 units. They also verify that break-even is reported as unreachable when price is at or below variable cost.

About Break-Even Calculator

Break-even is the point where a business stops losing money, and the arithmetic behind it is simpler than the language around it suggests. Only one number really matters: the gap between what you charge for something and what that specific something costs you to provide. That gap is the contribution, and every sale hands its contribution over to pay down the fixed costs that exist whether you sell anything or not - rent, salaries, software, insurance. Once those are covered, the same contribution becomes profit. Everything else in break-even analysis follows from that one relationship. This calculator makes the contribution figure visible rather than burying it, because it explains why a business with high fixed costs and thin margins needs an implausible volume to survive, and why a small price rise can matter more than a large increase in sales.

Using Break-Even Calculator

Fixed costs are the ones that do not change with volume: rent, salaries, subscriptions, insurance. Enter them for whatever period you are analysing, usually a month or a year.
The variable cost is what one additional unit costs you: materials, packaging, shipping, payment fees, any per-unit labour.
Contribution per unit is price minus variable cost, and break-even is fixed costs divided by that figure.
The result is rounded up, because a fraction of a unit cannot be sold. Selling the calculated whole number is the first point at which fixed costs are fully covered.
If price does not exceed variable cost the tool reports that break-even is unreachable, rather than returning a large number. At that price every extra sale loses money, so no volume ever helps.

Where break-even calculator helps

Judging whether a price rise beats a sales push

Raise the price slightly and watch the break-even units fall. Because the whole increase lands in contribution, a small rise usually moves the number more than a plausible increase in volume would.

Testing a subscription before committing

Add the annual cost of a new tool to fixed costs and see how many extra units it demands. If that figure looks unrealistic, the tool has to earn its place another way.

Before you use the result

Fixed costs are only fixed within a range. Doubling volume often forces new premises, more staff or a bigger plan, and each of those steps resets the calculation.
Variable cost per unit is rarely constant either. Bulk purchasing lowers it as volume rises, which means the true break-even is usually a little lower than a single-rate model suggests.
This assumes one product, or an unchanging mix. A business selling several products at different margins needs a weighted average contribution, not the figure for its best seller.
Break-even is about profit, not cash. A profitable business can still run out of money if customers pay slowly, and this calculation says nothing about timing.
Tax is excluded. Break-even here is the pre-tax point at which revenue covers total cost.

Questions about Break-Even Calculator

What counts as a fixed cost?

Anything you pay regardless of how much you sell - rent, permanent salaries, insurance, software. If the cost changes with each unit sold, it belongs in variable costs instead.

Why is the answer rounded up?

Because you cannot sell part of a unit. If the exact figure is 333.3, then 333 units leave you slightly short and 334 is the first point that clears the fixed costs.

Why does it say break-even is never reached?

Because the price is at or below the variable cost, so each sale loses money before fixed costs are even considered. No volume fixes that; the price or the cost has to change.

What is contribution margin?

The contribution expressed as a percentage of the price. It tells you what share of each sale is available to cover fixed costs and then become profit.

Is my cost data sent anywhere?

No. Everything is calculated in this tab, which matters given that these are usually figures a business would not publish.
