Free Amazon profit calculator: enter selling price, product cost, fees and ad spend to see net profit, margin and ROI per unit. Nothing is stored.

Net profit per unit = selling price − product cost − Amazon fees − ad spend per unit. Whatever remains after the cost to make the item, the fees Amazon takes and the advertising behind the sale is your real profit. Divide that by price for margin, or by your total cost for ROI. This calculator does all three instantly.

## FAQ

Q: How do you calculate Amazon profit per unit?
A: Net profit per unit = selling price − product cost − Amazon fees − ad spend per unit. Everything left after the cost to make the item, the fees Amazon takes, and the advertising attributed to that sale is your real profit. This calculator does that subtraction and also shows your margin and ROI.

Q: Which Amazon fees should I include?
A: Include every per-unit charge: the referral fee (a percentage of price), the FBA or fulfilment fee, and any per-unit storage, prep or return-handling cost you carry. Enter them as one combined fees figure. Leaving fees out makes your profit look higher than it really is.

Q: What is a healthy Amazon profit margin?
A: It varies by category and model, but many sellers aim for a net margin in the 15–30% range after all fees and ad spend. Thin-margin commodity products run lower; differentiated or private-label products can run higher. The right target is one that survives a bad-returns month and still funds restock.

Q: Does this include ad spend?
A: Yes — there is a field for ad spend per unit, because advertising is a real cost of each sale even though Amazon does not deduct it from your payout. To get ad spend per unit, divide a campaign's spend by the units it sold. Set it to zero to see profit before advertising.

Q: How does AIAdKing track true profit automatically?
A: Instead of a manual calculator, AIAdKing pulls your fees, costs and settlement data and computes true profit per SKU continuously — after referral and FBA fees, returns and ad spend. It also reconciles settlements and flags loss-making SKUs. It is a flat $29/month with no commission on ad spend; see the profit-reports feature.
