Ecommerce Profit Calculator FAQ
What is break-even ROAS?
The return on ad spend at which ads exactly pay for themselves: price divided by profit before ads.
Why include returns?
Returned orders usually cost shipping both ways and sometimes the product itself.
Which payment fee should I enter?
Your provider’s percentage and fixed fee per transaction.
Does it include fixed costs?
No. It shows contribution per order; cover fixed costs from total contribution.
Contribution per order
Many online shops look profitable on revenue but lose money per order once shipping, fees, ads and returns are counted. Knowing the profit per order is the basis for setting ad budgets and prices.
The break-even ad cost is a hard ceiling: campaigns that cost more per order than this lose money on every sale.
Re-run the numbers whenever an input changes – a supplier raises prices, a fee is updated or demand shifts – because small changes in costs or volumes often have a large effect on the result.
The calculator is deliberately simple: it uses the figures you enter and shows the arithmetic, so you can follow every step and repeat it in a spreadsheet when you want to build a fuller model.
