Free Ecommerce Break-Even Calculator: Units, Revenue and Daily Target
A break-even target turns a vague growth goal into the number of orders your offer must generate. This model keeps fixed costs, variable costs and selling price separate, then shows the volume needed for zero or target profit.
Break-even units = (fixed costs + target profit) ÷ contribution per unit. Round up to a whole unit for an operating target, and keep the period consistent across costs and volume.
How this free tool works
Find the ecommerce units and revenue needed to cover fixed costs, then model a target profit, daily sales target and profit at planned volume. The result is designed to be transparent: you can see the inputs, the formula and the assumptions instead of receiving a black-box score.
Break-even units = (fixed costs + target profit) ÷ (selling price − variable cost per unit). Break-even revenue = break-even units × selling price.
Best for
- Ecommerce founders setting a monthly sales target
- Operators deciding whether a product launch can cover overhead
- Teams testing how price or fulfillment costs change the volume required to profit
Frequently asked questions
How do I calculate break-even units?+
Subtract variable cost per unit from selling price, then divide fixed costs by that contribution per unit. Add a target profit to fixed costs when you want a profitable sales target rather than zero profit.
What should count as a variable cost?+
Include costs that rise with each order, such as COGS, shipping, fulfillment, payment fees, marketplace fees and any per-order acquisition cost you want the model to reflect.
What if variable cost is higher than price?+
The product has negative contribution per unit and cannot reach break-even through volume alone. Lower variable cost, raise realized price or change the offer before scaling traffic.
