Break-Even Calculator
Find how many units you must sell to cover fixed costs, your break-even revenue, and profit at different sales volumes — from price, variable cost, and fixed costs.
Rent, salaries, software, insurance — costs that don't change with sales.
Product cost, shipping, payment fees, commissions — costs per sale.
| Units sold | Revenue | Profit |
|---|---|---|
| 100 | $6,000.00 | −$2,500.00 |
| 150 | $9,000.00 | −$1,250.00 |
| 200 | $12,000.00 | $0.00 |
| 250 | $15,000.00 | $1,250.00 |
| 300 | $18,000.00 | $2,500.00 |
| 400 | $24,000.00 | $5,000.00 |
Break-even units = fixed costs ÷ (price − variable cost per unit). Selling ads-driven products? Pair this with the breakeven ROAS calculator to include ad spend per order.
Frequently asked questions
How is the break-even point calculated?
Break-even units = fixed costs ÷ contribution margin per unit, where contribution margin is selling price minus variable cost per unit. With $5,000 in fixed costs, a $60 price, and $35 variable cost, you need $5,000 ÷ $25 = 200 units per month.
What counts as a fixed cost vs a variable cost?
Fixed costs stay the same regardless of sales: rent, salaries, software subscriptions, insurance. Variable costs scale with each sale: product cost, shipping, payment processing fees, sales commissions, packaging.
What is the contribution margin ratio?
Contribution margin divided by price — the share of each sales dollar left after variable costs to cover fixed costs and then profit. Break-even revenue = fixed costs ÷ contribution margin ratio.
How do ads fit into break-even analysis?
Ad spend per order is a variable cost. If you acquire customers through paid ads, add expected ad cost per sale to your variable costs here — or use our breakeven ROAS calculator, which is built specifically for that.
