Calculate your result
Use figures from the same period and currency. Avoid mixing estimates with verified amounts without noting the difference.

Why this matters
Break-even is the minimum volume at which contribution covers fixed costs. It does not guarantee cash safety or a worthwhile return, but it exposes whether the sales target is economically possible. This calculator supports the decision about how many units or jobs must be sold before operating contribution covers the selected fixed costs. It is designed to expose the economic relationship among price, cost, volume and contribution before management relies on revenue growth alone.
Use fixed costs for one consistent period, selling price, variable cost per unit or job and a realistic volume forecast. Keep cost definitions consistent: a variable cost should change with the unit or job, while fixed costs belong to the selected period. Pricing guidance uses contribution and managerial-accounting relationships. GAAP and IFRS do not prescribe a selling price or a universal break-even threshold. Financial-reporting standards govern recognition and presentation; they do not guarantee that a quoted price is commercially sustainable.
How to act on the result
- Compare break-even units with practical capacity and historical demand
- Calculate a margin-of-safety target above break-even to absorb errors and slow periods
- Recalculate whenever price, supplier cost, commission or fixed overhead changes
Run at least three scenarios: current conditions, a realistic improvement and a downside case. Check whether the required volume fits practical capacity and whether the market will accept the price. The goal is not to produce a perfect percentage; it is to make the trade-off visible before a discount, quote or expansion commits cash.
Common mistakes and limits
Watch for mixing monthly and annual figures, treating semi-variable costs as fixed, excluding waste and assuming every unit sells at one price. Results exclude taxes, financing structure and complex cost behavior unless the inputs expressly include them. They are managerial estimates, not audited profit measures or GAAP/IFRS accounting policies. If break-even exceeds capacity or credible demand, redesign the offer, reduce fixed cost or stop the activity before committing more capital.
What this calculator answers
How many sales are required before the business stops losing money?
Formula and assumptions
Break-even units = fixed costs ÷ (selling price − variable cost per unit).
The result is an estimate. It is only as reliable as the inputs, and it does not account for every tax, legal, financing or operational consequence.
Worked example
Example: Monthly fixed costs are $5,000. The selling price is $100 and variable cost is $60, producing $40 contribution per unit. Break-even volume is therefore $5,000 ÷ $40 = 125 units. If the business currently sells 100 units, it needs 25 additional units to reach break-even under these assumptions.
How to interpret the result
- Low: no immediate gap or the entered position is comparatively protected.
- Medium: manageable pressure exists, but it should receive a dated correction plan.
- High: the problem can materially damage cash or operations and requires near-term action.
- Critical: the entered assumptions indicate immediate loss, shortage or survival risk.

Frequently asked questions
What happens if price is equal to variable cost?
There is no positive contribution to cover fixed costs, so a finite break-even point does not exist. The price, cost structure or offer must change.
Should fixed costs be monthly or annual?
Either period works, but fixed costs and expected unit volume must use the same period. This site’s example uses monthly figures.
How do I handle several products?
Use a weighted average contribution based on a realistic sales mix, or calculate each product separately before combining results.
Does reaching break-even mean the business has enough cash?
Not necessarily. Break-even is a profit relationship. Payment timing, inventory purchases, debt payments and deposits can still create a cash shortage.
