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.

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.
