Returns are the cost most often left out — at a 6% return rate the allowance is small but rarely zero.
How the Product Profit Calculator works
Most product profit calculations stop at materials and price. The costs that actually decide viability are the ones underneath — fees, fulfilment, advertising allocated per unit, and the returns that never get counted against the product that caused them.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
What costs should I include in product profit?
Materials or purchase cost, inbound freight, packaging, outbound shipping, marketplace commission, payment processing, advertising allocated to that product, and an allowance for returns and damages. Anything you would not spend if the product did not exist.
How do I allocate advertising to a single product?
Ideally by attributed spend from the ad platform. Failing that, divide total ad spend by units sold for a blended figure. Blended understates the cost of products you push hardest, so use attributed data wherever it exists.
Should I account for returns in product profit?
Yes, and it is routinely skipped. If 8% of units come back and half cannot be resold, the effective cost per sold unit is meaningfully higher. Apparel returns in particular can turn a profitable-looking product into a loss.
What if a product is unprofitable but drives other sales?
That is a loss leader, and it is a legitimate strategy — but only if you can demonstrate the attached sales. Measure basket composition rather than assuming. Most loss leaders that go unmeasured are simply losses.
