What is the break-even point?
The break-even calculator above finds the exact level of sales at which your business stops losing money and starts making it — the point where total revenue equals total costs, producing neither profit nor loss. Below the break-even point, you’re funding the gap out of pocket; above it, every additional sale contributes to profit. It is one of the most important numbers to know before launching a product, signing a lease, or committing to fixed costs.
Break-even analysis turns a vague worry (“will this work?”) into a concrete target (“we need to sell 1,250 units to cover our costs”). That target is something you can evaluate against your market: if break-even requires more sales than your market can plausibly deliver, the business model needs rethinking before you spend the money — not after.
The formula
Contribution Margin = Price per unit − Variable cost per unit
Break-Even Units = Fixed costs / Contribution margin
Break-Even Revenue = Break-Even Units × Price per unit- Fixed costs — costs that don’t change with volume: rent, salaries, software, insurance.
- Price per unit — what you charge for each unit sold.
- Variable cost per unit — costs that scale with each unit: materials, payment fees, shipping.
The key concept is contribution margin — the portion of each sale left over after variable costs, available to chip away at fixed costs. Once contribution margin has covered all fixed costs, you’ve broken even.
Worked example
Fixed costs of $50,000, a price of $100/unit, and variable cost of $60/unit:
Contribution Margin = $100 − $60 = $40 per unit
Break-Even Units = $50,000 / $40 = 1,250 units
Break-Even Revenue = 1,250 × $100 = $125,000You must sell 1,250 units ($125,000 in revenue) just to cover costs. Unit 1,251 is your first profitable sale, contributing $40 to profit — as does every unit after it.
Watch the leverage of price and cost. If you raise the price to $110 (contribution margin $50), break-even drops to 1,000 units — a 10% price increase cut your break-even by 20%. Conversely, if variable costs rise to $70 (contribution margin $30), break-even jumps to 1,667 units. Break-even is acutely sensitive to contribution margin, which is why protecting margin matters so much.
Benchmarks and interpretation
There’s no universal “good” break-even point — it depends entirely on your market size and how fast you can reach it. The useful questions are:
- Is break-even achievable in a reasonable time? Compare break-even units to realistic monthly sales. If it takes three years of sales to break even on a one-year commitment, the model is fragile.
- How much margin of safety do you have? If you expect to sell 2,000 units and break-even is 1,250, you have a comfortable 38% cushion. If you expect 1,300, you’re one bad month from a loss.
If contribution margin is zero or negative (variable cost ≥ price), there is no break-even point at all — you lose money on every unit, and more volume only deepens the loss. The calculator flags this case, and it’s a signal that pricing or costs must change before anything else.
How to use it
Use break-even analysis as a go/no-go filter before taking on fixed costs, and as a target once you’re operating. Three levers move your break-even point: raise prices, cut variable costs, or reduce fixed costs. Because break-even = fixed costs ÷ contribution margin, improving contribution margin (via price or variable cost) has a compounding effect, while cutting fixed costs lowers the hurdle directly.
A practical extension: to find the sales needed for a target profit rather than just break-even, add the target profit to fixed costs before dividing. Wanting $20,000 profit in the example above means covering $70,000 ÷ $40 = 1,750 units. This turns break-even analysis into a planning tool, not just a survival check.
Remember that break-even assumes your fixed and variable cost split is accurate and stable. Step-changes in fixed costs (hiring, a bigger facility) reset the break-even point, so recalculate whenever your cost structure changes.
Frequently asked questions
What is the break-even point? The break-even point is the level of sales at which total revenue exactly equals total costs — no profit, no loss. In units, it equals fixed costs divided by the contribution margin per unit (price minus variable cost per unit).
What is contribution margin? Contribution margin is the amount each unit sold contributes toward covering fixed costs, equal to the selling price minus the variable cost per unit. Once enough units are sold to cover all fixed costs, every additional unit’s contribution margin becomes profit.
