Work out how to calculate break even point in units and dollars from three numbers: fixed costs, price per unit and variable cost per unit. The result also shows the contribution margin on every sale.
Results update automatically as you type. The break-even point is where total revenue equals total costs.
How to Calculate Break-Even Point in Units and Dollars
Subtract variable cost from price to get the contribution margin, divide fixed costs by it for units, then multiply units by price for dollars. With $10,000 of fixed costs, a $50 price and a $30 variable cost, each sale contributes $20, so you need 500 units, or $25,000 in sales.
- Contribution margin: $50 − $30 = $20 per unit.
- Break-even units: $10,000 ÷ $20 = 500 units.
- Break-even revenue: 500 × $50 = $25,000.
- Contribution margin %: $20 ÷ $50 × 100 = 40%.
Break Even Point Formula in Units
The break-even point is the sales volume where total revenue stops falling short of total costs. The tool uses your fixed costs, price and variable cost per unit to find that point in both units and dollars.
Formula: Contribution Margin = Price per Unit − Variable Cost per Unit. Break-Even Units = Fixed Costs ÷ Contribution Margin (rounded up to the next whole unit). Break-Even Revenue = Break-Even Units × Price per Unit. Contribution Margin % = (Contribution Margin ÷ Price per Unit) × 100.
- Fixed costs: total costs that don't change with sales volume, such as rent, salaries and insurance
- Price per unit: what you charge for one unit of your product or service
- Variable cost per unit: the cost that scales directly with each unit sold, such as materials or commission
How Many Units Must Be Sold to Break Even? Examples
| Fixed Costs | Price/Unit | Variable Cost/Unit | Break-Even Point |
|---|---|---|---|
| $10,000 | $50 | $30 | 500 units ($25,000) |
| $8,000 | $40 | $25 | 534 units ($21,360) |
| $15,000 | $75 | $45 | 500 units ($37,500) |
| $3,000 | $20 | $12 | 375 units ($7,500) |
| $25,000 | $60 | $45 | 1,667 units ($100,020) |
Separating Fixed and Variable Costs
Your answer is only as good as the way you sort your costs, and that is where most errors creep in.
- Fixed costs stay the same whatever you sell in a period: rent, salaries, insurance and software subscriptions.
- Variable costs rise with each unit: materials, packaging, shipping, payment processing and sales commission.
- Semi-variable costs, such as a phone plan with usage charges, can be split into a fixed base and a per-unit part.
To calculate a monthly break even point in units, enter monthly fixed costs and the result is a monthly unit target. Keep one time frame throughout. Discounts count too: enter the average price customers actually pay, not the list price.
Your contribution margin break even point moves fast when the margin is thin, since a small cost rise can push it sharply higher. Rerun the numbers with a few price and cost scenarios, and because sales are rarely even from month to month, keep a cash buffer beyond the target. The break-even point article on Wikipedia covers the theory and its limits, which helps when you present the results to a lender or partner.
Common questions about break-even point
How do you calculate break even point in units and dollars?
Divide fixed costs by the contribution margin per unit (price minus variable cost) for units, then multiply by price for dollars. $10,000 ÷ ($50 − $30) = 500 units, and 500 × $50 = $25,000.How many units must be sold to break even?
As many as it takes for the contribution margin to cover fixed costs, rounded up to a whole unit. With $8,000 of fixed costs and a $15 margin per unit, that is 533.3, so 534 units.What counts as a fixed cost versus a variable cost?
Fixed costs stay the same regardless of how much you sell, like rent, insurance and salaried wages. Variable costs rise and fall with each unit sold, like raw materials, packaging or sales commission.What happens if my variable cost is higher than my price?
The calculator will flag that price must exceed variable cost. Selling below your variable cost means you lose money on every unit, so no sales volume could ever reach break-even.How can I lower my break-even point?
Raise your price, cut variable cost per unit, or reduce fixed costs. Any of the three shrinks the number of units you need to sell before covering all your costs.Does the break-even point include any profit, or just covering costs?
Just covering costs. At the break-even point, revenue exactly equals total costs and profit is zero, and every unit sold beyond it adds its full margin to profit.Related Calculators
