Amazon Net Profit Calculator
Business-level profit, refunds included properly.
Amazon revises fee schedules at least annually and adds new surcharges more often. These defaults are a starting point — the figures in your own fee preview are the ones that describe your ASINs.
Net profit

24.1% of gross sales
Advertising is charged on gross sales including the orders that were later refunded, so refunds cost you twice — the sale and the spend that won it. That is why a 5% refund rate hurts more than 5%.
How the Amazon Net Profit Calculator works
Refunds cost you twice: the sale and the advertising that won it. Ad spend is charged on gross orders including the ones later refunded, which is why a 5% refund rate hurts by more than 5% — and why netting refunds out before applying ad ratios understates the damage.
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
How do I calculate Amazon net profit?
Gross sales less refunds, less cost of goods on the units actually kept, less Amazon fees, less advertising on gross orders, less fixed overheads. Advertising is the line most often applied to the wrong base.
Why do refunds hurt more than their percentage?
Because you paid to acquire the sale and that spend is not refunded. On a product with 10% advertising cost, a refund destroys the margin plus the acquisition cost of the order.
What overheads should I include?
Software subscriptions, prep and warehousing, accountancy, your own salary if you take one, and any staff. Sellers who omit their own time report profits that vanish the moment they hire a replacement.
How often should I calculate this?
Monthly. Amazon's own reports are settlement-period based and do not align to calendar months, which is why sellers with rising sales are frequently surprised by their year-end numbers.
