Break-even point is the sales volume where total revenue covers total costs - the moment each additional sale becomes profit.
What is the Break-Even Point Calculator?
This free break-even calculator shows how many units and how much revenue you need before you turn a profit. It works for any Shopify or ecommerce store and is the starting point for pricing, budgeting, and deciding how much you can spend to grow.
How this calculator works
Enter your monthly fixed costs, your selling price per unit, and your variable cost per unit. The tool calculates your contribution margin, price minus variable cost, and divides fixed costs by it to find the units you must sell, then multiplies by price for break-even revenue.
How to read your result
The headline is your break-even units per period. The rows show your contribution margin per unit and as a percentage, plus the revenue that volume represents. To lower your break-even point, raise price, cut variable cost per unit, or reduce fixed overhead.

Frequently asked questions
How do I calculate the break-even point?
Divide your fixed costs by your contribution margin per unit (selling price minus variable cost per unit). The result is the number of units you must sell to cover all costs. This calculator does it instantly.
What is contribution margin?
It is the money left from each sale after variable costs, available to cover fixed costs and then profit. A higher contribution margin means a lower break-even point.
How can I lower my break-even point?
Raise your price, reduce variable cost per unit, or cut fixed overhead. Small improvements to margin reduce break-even volume quickly.
