3.4Break-even point
The essentials in 30 seconds
- The break-even point is the turnover for which the result is nil: below you lose, above you earn.
- It relies on the fixed costs (paid even without selling) / variable costs (proportional to activity) split and the contribution margin.
- Break-even = fixed costs / contribution margin ratio; the break-even date expresses it in time; high fixed costs = high break-even = riskier.
Running mini-case — Rachid: how much to sell to avoid losing?
Rachid wants to hire and hesitates: his fixed costs will rise. He splits his fixed costs (rent, fixed wages) from his variable ones, calculates his contribution margin then his break-even: until he reaches it, every sale first covers fixed costs. He now knows which figure to target — and that hiring raises that bar.
Sequel of cases 3.1-3.3 — Rachid prices his minimum target.
1. The activity level that balances
The break-even point answers: from which activity level does the business start making money? It is the turnover for which the result is nil — below, you lose; above, you earn.
You must split fixed costs (rent, insurance — paid even without selling) and variable costs (materials, commissions — proportional to activity). Each sale generates a contribution margin (price minus variable costs) that must first cover fixed costs; afterwards, each sale becomes profit.
2. Formula, break-even date and risk
Break-even = fixed costs / contribution margin ratio. The break-even date expresses the same threshold in time: the date of the year it is reached. Example: fixed costs 100,000, contribution margin ratio 40% → break-even = 100,000 / 0.40 = 250,000 of turnover for a nil result.
A precious decision tool: set a minimum target, assess the risk (high fixed costs = high break-even = result sensitive to downturns), simulate a price cut or a cost rise. Understanding break-even means knowing how much to sell to avoid losing — a compass.
🔎 Concrete example — Cost structure and risk
Rachid applies the formula to his case.
Fixed costs 100,000, contribution margin ratio 40%.
→ Break-even = 100,000 / 0.40 = 250,000 of turnover (nil result).
Mostly fixed costs → high break-even, result sensitive to downturns.Result: a clear target and a measure of risk.
Reflex: simulate a price cut or a cost rise.
Section vocabulary
- Break-even point
- Turnover for which the result is nil (neither profit nor loss); beyond it, the business earns.
Simple example: with 100,000 fixed and 40% margin, Rachid must sell 250,000 to balance.
What it is not: the maximum profit or total costs.
Reflex: know your break-even by heart before any sales target.
- Fixed costs
- Costs independent of activity volume (rent, insurance, fixed wages).
Simple example: Rachid's rent, paid even in months with no sales.
What it is not: the raw materials following each sale.
Reflex: list what is paid whatever happens, even at a standstill.
- Variable costs
- Costs proportional to activity (raw materials, commissions).
Simple example: the goods Rachid buys for each sale.
What it is not: rent or insurance, due even with no activity.
Reflex: one misclassified cost = one wrong break-even: sort carefully.
- Contribution margin
- Selling price minus variable costs; what remains to cover fixed costs then generate profit.
Simple example: each sale of Rachid first fills fixed costs, then becomes profit.
What it is not: the net result or the available cash.
Reflex: calculate your margin ratio before any break-even calculation.
- Break-even date
- Break-even point expressed in time: the date of the year it is reached.
Simple example: Rachid knows at which date he really starts earning.
What it is not: a customer or supplier payment term.
Reflex: translate break-even into a date to steer the year.
In practice — Calculating the break-even point
- Split fixed costs (independent of volume) and variable costs (proportional to activity).
- Calculate the contribution margin (price minus variable costs) and its ratio (margin / turnover).
- Calculate break-even = fixed costs / contribution margin ratio.
- Express the break-even date in time (date reached) and use both to set a sales target and assess risk.

"Our break-even is 250,000: below, we lose; above, we earn. Our fixed costs impose that bar, and any hiring raises it. Minimum target this half-year: secure that figure before any new project."

SME Algiers
Recalculate break-even when fixed costs move (rent, hiring): yesterday's bar can be wrong today.
Trading / retail
Play on the margin ratio (prices, supplier discounts) to lower break-even without touching fixed costs.
Services
High fixed wages = high break-even: measure the safety margin before accepting a price cut.
✓ Best practices
- Carefully split fixed and variable costs: the basis of the calculation.
- Use break-even to set a minimum sales target.
- Simulate: price cut, cost rise, new investment.
✗ Common pitfalls
- Misclassifying a cost (fixed vs variable) and falsifying break-even.
- Ignoring the risk of high fixed costs (high break-even).
- Forgetting the safety margin (how much sales can fall).
Key takeaways
- The break-even point is the turnover for which the result is nil.
- It relies on the fixed costs / variable costs split.
- Break-even = fixed costs / contribution margin ratio; the break-even date expresses it in time.
- High fixed costs = high break-even = riskier activity.

Frequently asked questions
Why do high fixed costs make a business riskier?
Because they raise the break-even point and make the result sensitive to activity changes: the business pays its heavy fixed costs whatever happens. If activity falls below break-even, it dives quickly into losses. Conversely, mostly variable costs cushion downturns. Cost structure is therefore a major risk factor.
Is break-even useful beyond theory?
Yes: setting a minimum sales target, assessing a project's viability, measuring a safety margin, simulating decisions (price cut, rent rise, investment). A compass every manager or project leader should keep in mind.
