How we calculate
Profit per unit
price - unit cost - commission - logistics - returns - tax - ads
Commission, tax and ads are a percentage of the price. Returns are return rate × logistics: the item is resold, the return shipping is lost.
Margin and ROI
margin = profit ÷ price, ROI = profit ÷ unit cost
Break-even ad share
(profit + ads) ÷ price
The share of revenue you can give to ads without going into a loss.
Break-even price
(unit cost + logistics + returns) ÷ (1 - commission - tax - ad share)

Discuss this with the teamHonest about the math
You enter the platform rates yourself: commissions and logistics fees differ by category and keep changing, so we don't hard-code them. Returns are simplified to return shipping - if a returned item can't be resold, the loss is higher. Storage, inbound fees and penalties are not included.
This is a reference point, not a promise of results. Our prices here are “from” prices, the exact amount is fixed in writing after an audit.
Questions
What is ACoS here?
Ad share of revenue: ad spend ÷ revenue. The calculator shows the break-even share - above it, ads eat all of the profit.
Why don't you fill in the platform commission?
It depends on the category and the fulfilment model, and it changes. The exact figure is in your seller dashboard, which keeps the calculation honest.
What else is left out?
Storage, paid inbound, penalties and seller-funded discounts. If you have them, add them to logistics per unit.
