Estimate merchant-fulfilled Amazon profit after referral fees, product cost, seller shipping, duty, tax, PPC, returns, and true net margin.
FBM net profit = sale price - product cost - referral fee - seller shipping - duty - tax - PPC - return loss
- Amazon referral fees
- Merchant-fulfilled shipping costs
- Product cost and landed cost
- Duty, VAT, or tax assumptions
- PPC or advertising spend
What it calculates
One margin view, all the major inputs.
The calculator keeps the full cost stack together so the final margin reflects more than sale price minus product cost.
Separate seller-controlled shipping costs from marketplace referral fees.
Keep Amazon category fees visible when testing product economics.
Combine product cost, shipping assumptions, and taxes before margin is judged.
Model supported Amazon marketplaces without rebuilding the calculation.
Include ACoS so FBM profit reflects real selling costs.
Estimate the margin impact of refunds and product loss.
How the calculation works
FBM profit depends heavily on referral category, shipping assumptions, advertising, and return loss. Profitlee keeps those inputs visible before you commit to inventory.
If a merchant-fulfilled product sells for $24.99, Profitlee subtracts product cost, Amazon referral fees, shipping, duty or tax assumptions, PPC, and return loss to estimate net margin.
