Break-Even Point
Why it matters
The number turns a vague ambition like "get profitable" into a target: this many customers, this much revenue, this month. Without it, pricing and hiring decisions are guesses, because nobody can say how many extra sales a new cost demands.
It also shows which lever is cheapest. Raising the price, cutting a fixed cost or lowering the delivery cost each moves the break-even point by a different amount, and the calculation lets a founder compare them before committing.
And it sets a clear limit on risk. Knowing that a new hire adds, say, 25 customers to the break-even point makes it obvious whether the pipeline can carry that hire, and how many months of losses the business will fund while it catches up.
What it is
At break-even, a business earns exactly what it spends. Below that level it loses money on the period. Above it, each extra sale adds to profit. The point can be stated as a number of customers, a number of units or an amount of revenue.
It rests on a split of costs. Fixed costs stay the same whatever you sell, such as salaries, rent and software subscriptions. Variable costs rise with each sale, such as payment fees, materials or delivery. What each sale leaves after its own variable cost is the contribution margin, and the contribution margin pays down the fixed costs until none remain.
Break-even in profit terms is not the same as cash break-even. A business can be at break-even on paper and still be short of cash, for example when customers pay after 60 days. See Cashflow for that gap.
Common mistakes
- Treating a cost as fixed when it grows with volume, such as payment fees or support time.
- Forgetting to move the number after a price change.
- Reading break-even as success. It only means the business has stopped losing money.
How to calculate it
- Add up fixed costs for the period: rent, salaries, subscriptions, anything that does not change with volume.
- Work out the contribution margin per sale, which is the price minus what that one sale costs to deliver.
- Divide fixed costs by the contribution margin. The result is the number of sales needed to break even.
- Recalculate whenever a fixed cost changes, such as a new hire or a bigger office.
- Show the number where the whole team can see it, not only in a spreadsheet nobody opens.
