When Will You Break Even?
Break-even is the point where total revenue equals total cost. The standard break-even formula divides fixed cost by contribution margin per unit, which tells you how many units you must sell before the business starts to make money rather than lose it.

- Break-even is where total revenue equals total cost.
- Break-even units equal fixed costs divided by contribution margin per unit.
- Calculating the threshold beats talking vaguely about getting profitable.
- Test it under different price and cost assumptions, since both move the line.
What this means
Founders often talk about getting profitable without calculating the threshold. Break-even makes it concrete: it is the sales level where revenue exactly covers total cost, so every unit beyond it contributes to profit.
Break-even formula: Break-even units equal fixed costs divided by the contribution margin per unit, where contribution margin is price minus variable cost per unit.

How Startup Suite helps
Startup Suite's Forecast Engine helps founders test the break-even threshold under different price and cost assumptions, so you can see how a price change or a cost cut moves the point you need to reach.
Forecast Engine: break-even you can move
- See break-even units update as price or cost changes.
- Connect the threshold to your full revenue forecast.
- Test whether a price increase reaches break-even sooner.
A practical founder example
Suppose fixed costs are 12,000 dollars, the price is 50 dollars, and variable cost per unit is 20 dollars. Contribution margin is 50 minus 20, which is 30 dollars. Break-even units are 12,000 divided by 30, which is 400 units.
At 400 units you cover your costs. Unit 401 is where the business starts to make money. Raise the price or cut variable cost and that 400 falls.

Frequently asked questions
What is contribution margin?
Price minus variable cost per unit, the amount each sale contributes toward covering fixed costs.
Does break-even include all costs?
It covers fixed and variable operating costs; remember to keep one-time costs separate when you plan.
What lowers the break-even point?
A higher price, a lower variable cost, or lower fixed costs all reduce the units you need.
