Formula

`Margin = (Revenue − COGS − FBA − Referral − PPC) ÷ Revenue × 100`

True Amazon profit margin accounts for all costs: product cost, FBA fulfilment, referral fees, and your per-unit PPC contribution.

Example `Price $49 · COGS $12 · FBA $9 · Referral $7.35 · PPC $4 → Margin ≈ 33.9%`

FAQs

What is a good Amazon profit margin? After all fees and PPC, a net margin of 20–30% is strong. Under 10% is fragile and leaves no room for price pressure or algorithm changes. Top operators target 25–40%. Are Amazon referral fees included in FBA fees?

The concept

## Four cost layers, one number

Amazon sellers often calculate margin from price minus COGS alone, missing FBA fulfillment fees, the category referral fee (8–15%), and the per-unit PPC contribution. All four have to be subtracted to get a margin figure you can actually make pricing and ad-spend decisions from.

## Margin is the ceiling for every other decision

Your margin determines your break-even ROAS, how aggressively you can bid on PPC, and how much room you have to absorb a fee increase or price war. A thin-margin SKU has almost no strategic flexibility — a healthy margin gives you options.

Common mistakes

## What sellers get wrong

- ✕ Calculating margin from price minus COGS only, without FBA fees, referral fees, or PPC cost per unit factored in.
- ✕ Using a category-average referral fee instead of the actual fee tier for the specific product, which varies significantly by category.
- ✕ Not re-running the calculation after a price change — a small price drop can shift margin percentage far more than sellers expect.
