Break-Even Calculator
Work out how many units you need to sell — and how much revenue that means — before your business, product or side project stops losing money and starts making a profit.
Rent, salaries, software, insurance — costs that don't change with sales.
Materials, shipping, payment fees — costs for each unit sold.
Break-even units = (fixed costs + target profit) ÷ (price − variable cost per unit). The contribution margin is what each sale contributes towards fixed costs. Assumes one price, constant costs per unit and that everything you make is sold — real businesses with several products, discounts or volume pricing need a more detailed model. Not financial advice.

Contribution margin per unit
Each unit sold contributes $27.00 towards your $12,000.00 of fixed costs. The exact figure is 444.44 units, rounded up because you can't sell part of a unit.

About this tool
Break-even point = fixed costs ÷ (price − variable cost per unit). With $12,000 of monthly fixed costs, a $45 price and $18 of variable cost per unit, each sale contributes $27, so you need 445 sales a month (444.4, rounded up) — $20,025 of revenue — to break even.
Fixed costs don't change with sales: rent, salaries, software subscriptions, insurance. Variable costs scale with each unit: materials, packaging, shipping, payment processing and marketplace fees. The difference between price and variable cost is the contribution margin — what each sale contributes towards covering fixed costs, then profit.
The model assumes a single price and constant costs per unit. If you sell several products, use an average price and variable cost weighted by your sales mix, and remember that discounts and volume pricing change the result. Use it for planning and pricing decisions, not as financial advice.
