How is Amazon profit calculated?
Net profit is what's left of the buyer's payment after VAT, Amazon fees, fulfillment, product cost, returns, ads and your share of fixed costs.
- Sales total = item price + shipping charged to the buyer. Outside the US you enter it in local currency and it's converted at the ECB reference rate.
- VAT = sales total − sales total ÷ (1 + VAT rate). In the UK and EU the VAT inside the price isn't yours; US and Canada prices exclude tax.
- Referral fee = sales total × category rate, never below the minimum. US media items also pay a $1.80 closing fee.
- FBA fulfillment fee = rate card lookup by size tier, fee weight and price band. Fee weight is the greater of unit weight and dimensional weight (L × W × H ÷ 139); small standard uses unit weight only.
- Storage per unit = monthly rate per cubic foot × unit volume × average units stored ÷ monthly units sold.
- Net profit = sales total − VAT − Amazon fees − tax on fees − fulfillment and storage − product cost − returns reserve − ads − fixed cost share.
- Net margin = net profit ÷ sales total. ROI = net profit ÷ (product cost + logistics you pay yourself).
- Break-even and target-margin prices: because FBA price bands and tiered referral fees make the formula piecewise, the tool narrows the price step by step until profit hits zero or your target margin.
FBA or FBM?
With FBA, Amazon stores, packs, ships and handles customer service for a fee. With FBM, you do that work and carry its cost.
| FBA (Amazon ships) | FBM (you ship) | |
|---|---|---|
| Fulfillment | Rate card by size, weight and price band | Your own carrier rates |
| Storage | Monthly per cubic foot; higher Oct–Dec | Your warehouse or a forwarder |
| Inbound | Placement fee (minimal splits) or free Amazon-optimized splits | None |
| Aged inventory | Surcharge from 181 days | None |
| Returns | Processing fee above the return-rate threshold | You absorb returns |
| Prime badge | Yes | Depends on Seller Fulfilled Prime |
