Break-Even Calculator
The Break-Even Calculator works for any product or business — not just Shopify. Enter your fixed monthly costs, the variable cost per unit, and your selling price. We'll show the units you need to sell to cover costs, the revenue that represents, and how many days it will take if you enter your average daily sales. It's the single most important number for every founder.
