THE MATH

How to calculate Amazon FBA profit

Your real FBA profit margin is your selling price minus every cost Amazon touches before money reaches your account: the Amazon referral fee (8–20% depending on category), the FBA fulfillment fee(picking, packing, shipping — set by your product's size and weight), monthly storage fees, your inbound shipping to Amazon warehouses, your advertising spend, a reserve for customer returns, and your cost of goods (including any import tariffs).

The formula: Net = Revenue − Referral − FBA fee − Storage − Shipping − PPC − Returns − COGS

Your real margin is Net ÷ Revenue × 100. Your break-even price is the minimum selling price where Net = 0 — useful for knowing how low you can go during deals or price wars.

The hidden costs

Why most FBA calculators are wrong

Most FBA profit calculators — including Amazon's own — show you two numbers: the referral fee and the FBA fulfillment fee. That's it. The result looks like a healthy margin. The gap between that number and your real margin is where most FBA businesses quietly lose money.

What they miss:

  • PPC (advertising) — the single biggest omission. Most sellers spend 10–20% of revenue on Amazon ads. Skip this and your margin looks 10–20 points higher than reality.
  • Returns — clothing returns 15–30% of units. Each return costs you the return processing fee plus the probability the item can't be resold.
  • Import tariffs — for sellers sourcing from China, tariffs add 30–145% to COGS. This alone can flip a profitable product to a losing one.
  • Inbound shipping — freight to Amazon warehouses costs $0.50–$3.00+ per unit depending on your supplier location and shipment size.

The headline margin (price minus COGS) is the number that gets you excited about a product. The real margin is the number that determines whether you stay in business.

Fee structure

How Amazon FBA fees work in 2026

Amazon charges two primary fees for FBA sellers: a referral fee (a percentage of the sale price, by category) and an FBA fulfillment fee (a per-unit charge by size and weight tier). On top of those sit storage, an inbound placement fee, a low-inventory fee, and — new in 2026 — a 3.5% fuel & logistics surcharge on fulfillment fees, effective April 17, 2026. The 2026 schedule took effect January 15, 2026 and raised fulfillment fees by about $0.08 per unit on average.

Referral feesare 15% for most categories, 8% for consumer electronics, and reach 45% for Amazon device accessories, with a $0.30 minimum per item. Some categories are price-tiered (Health & Personal Care is 8% under $10, then 15%).

QUESTIONS

Frequently asked questions

The fee schedule uses Amazon's published 2026 US rates (effective January 15, 2026) and is verified against Amazon's official fee pages. The calculation is accurate when you input your real costs. The key variable most sellers underestimate is PPC — the default 15% is a reasonable average, but high-competition categories can be 25–40%. Always input your actual ACoS for the most accurate result.
For a typical $25 standard-size product, expect a referral fee of about $3.75 (15% of the sale price) plus an FBA fulfillment fee of roughly $3.70–$4.60 depending on weight, plus a 3.5% fuel & logistics surcharge on the fulfillment fee. That is about $7.50–$8.50 in Amazon fees before you subtract your product cost, inbound shipping, storage, PPC, and returns. Use the calculator above with your real category and weight for an exact number.
Introduced in 2024 and continuing in 2026, the inbound placement service fee is charged when you send inventory to a limited number of Amazon receiving locations instead of distributing it across the network yourself. It runs roughly $0.14–$1.50 per unit depending on weight and how you split shipments; sending to all of Amazon's recommended locations reduces or removes it.
FBA charges a per-unit fulfillment fee (about $3.20–$7 for standard-size units in 2026) but includes pick, pack, ship, and Prime eligibility. FBM (you ship yourself) avoids that fulfillment fee but you pay your own postage, packaging, and labor, and you lose the built-in Prime badge. FBA usually wins on small, fast-moving items; FBM can win on heavy, slow, or high-value items where your own shipping beats Amazon's fee. Model both by comparing the FBA fee here against your real per-order shipping cost.
A fee calculator shows only Amazon's fees. A revenue calculator (like Amazon's own) shows sale price minus fees — your payout, not your profit. A profit calculator — this one — goes further and subtracts your cost of goods, inbound shipping, PPC, returns, and tariffs to show the number that actually lands in your pocket.
Yes. FBA fulfillment fees depend on your product's size tier (dimensions and weight). Referral fees depend on your category. Storage fees depend on how long inventory sits in Amazon's warehouse. This calculator lets you select your exact size tier and category to get accurate numbers.
A real margin (after all costs including PPC) of 15–25% is healthy for most FBA businesses. Under 10% leaves you vulnerable to fee increases, ad cost inflation, and inventory variability. Over 30% is excellent. The key is knowing your real number — not the headline margin that excludes PPC and returns.
Tariffs are applied to your COGS (product cost). If you source from China and face a 30% tariff, a $5 product now costs $6.50 to land — that $1.50 difference comes straight out of your margin. For thin-margin products, tariffs at 30%+ can turn a profitable product unprofitable overnight. Use the tariff slider to model your exact exposure.
Absolutely. PPC (advertising) is one of the largest costs in your P&L and the most commonly omitted from "back of the napkin" margin math. Most Amazon sellers spend 10–20% of revenue on ads. If you ignore it, your real margin looks dramatically better than it actually is — which leads to bad sourcing and pricing decisions.
Amazon's calculator shows you fulfillment fees and referral fees only. It doesn't include PPC costs, return reserves, inbound shipping, or tariffs. Those omitted costs often represent 20–30 percentage points of real margin. This calculator shows you the full picture.
Yes. SellerForge's Listing Audit module connects to your Amazon account and pulls real data — actual ACoS, real return rates, and fee history — for every ASIN in your catalog. It automatically flags products losing money and shows where your margin is being eroded.
