How it works
An FBA calculator works out the profit on a product sold through Amazon's Fulfillment by Amazon. From the sale price it subtracts your product cost, Amazon's referral fee (a percentage of the sale), and the FBA fulfillment and storage fees — what's left is your profit, and dividing that by the sale price gives your margin.
FBA profit & margin
Profit = Sale price − product cost − referral fee − FBA fees Margin% = Profit ÷ Sale price × 100
- referral fee
- Amazon's cut, typically ~15% of the sale
- FBA fees
- pick, pack, ship, and storage
Worked example
- Sale price = $25, product cost = $7
- Referral fee 15% = $3.75, FBA fee = $5.50
- Profit = 25 − 7 − 3.75 − 5.50
Profit = $8.75 — a 35% margin.
Good to know
- Oversized and heavy items carry much higher FBA fees — check the size tier before sourcing.
- Long-term storage fees add up on slow-moving inventory, eating into margin.
- Factor in returns, PPC ad spend, and inbound shipping for a true net profit.
