Amazon FBA profit calculator
Profit is what is left after Amazon’s cut and what you paid for the unit (and inbound, if you track it). This page forces COGS into the form so you do not celebrate a fee estimate that still loses money.
Estimate only — not your seller payout.
When to use — and when not to
When to use
Vendor quotes in hand; comparing two suppliers; stress-testing a price drop.
When not to
Fee education without cost → FBA fee calculator. Ad-heavy launches need a separate PPC model — optional ad field is a stub, not TACoS strategy.
Assumptions
Same FBA fee engine. profit = price − amazon_fees − cogs − inbound − ads (ads optional). Returns reserve not modeled unless user enters Other.
Worked examples
Price $24, fees ≈ $8.10, COGS $9, inbound $1.20
Profit ≈ $5.70 (~23.8%)
Add 10% ads on price
−$2.40 → profit ≈ $3.30
Ads are not optional if you cannot rank without them.
How it calculates
Fees as FBA pages → subtract COGS / inbound / ads → margin %
Stack the fee lines, then read payout (and profit when costs are entered).
- Enter price, referral, and fulfillment estimate.
- Add COGS and inbound per unit.
- Optionally add ads %.
- Read profit and margin.
Common traps
- Landed COGS beats factory quote alone.
- Returns on apparel can need an explicit reserve.
- Storage over Q4 spikes — annualize.
- Margin on price ≠ ROI on inventory.

FAQ
Take the list price, subtract referral and fulfillment (and ads/storage if you entered them), then subtract COGS and inbound per unit. What remains is unit planning profit — useful for restock decisions, not a full company P&L.
