Now that you know your margin

Build the launch plan that protects it

A tight margin only stays tight if your keywords, listing, and PPC are dialed in from day one. Launch Fast uses AI to build your complete launch blueprint — keyword strategy, listing copy, and launch sequence — so you don't burn your margin on trial and error.

How Amazon FBA fees work

Amazon deducts three types of fees from every FBA sale. Understanding each one helps you price products for sustainable margins.

01

Referral Fee

Amazon charges a percentage of your selling price as a referral fee, ranging from 8% (Electronics, Grocery) to 17% (Clothing). This is paid on every sale regardless of fulfillment method.

02

FBA Fulfillment Fee

A per-unit fee covering pick, pack, and shipping. It depends on your item's size tier (Small Standard vs. Large Standard) and weight. Ranges from $3.06 to $6.10+ for standard-size items.

03

Monthly Storage Fee

Charged per cubic foot of space your inventory occupies in Amazon's fulfillment centers. $0.78/cu ft (Jan–Sep) and $2.40/cu ft (Oct–Dec). Keeping lean inventory reduces this cost significantly.

04

Size Tier

Amazon classifies products as Small Standard (longest side ≤15", median ≤12", shortest ≤0.75", ≤16 oz) or Large Standard (up to 18"×14"×8", ≤20 lb). Smaller tiers mean lower fees.

Frequently asked questions

How does Amazon calculate FBA fees?

Amazon charges two main fees per sale: a referral fee (a percentage of the selling price, typically 8–17% depending on category) and an FBA fulfillment fee (a flat per-unit charge based on product size and weight). There is also a monthly storage fee charged per cubic foot of warehouse space used.

What is a good profit margin for Amazon FBA?

Most experienced FBA sellers target a minimum net margin of 20–30% after all Amazon fees, product cost, and shipping. Margins below 15% leave little room for PPC advertising costs, returns, and account fees. Products with 30%+ margins are considered strong candidates.

What is the referral fee on Amazon?

Referral fees range from 8% to 17% of the selling price depending on the product category. Electronics and Grocery items are charged 8%, most categories are 15%, and Clothing & Accessories is 17%. The fee is deducted from each sale automatically.

Does this calculator include Amazon PPC costs?

This calculator covers the core Amazon-charged fees: referral fees, FBA fulfillment fees, and storage fees. It does not include PPC advertising spend, which varies widely by product and keyword. Many sellers add $1–3 per unit in PPC costs when modeling profitability.

What is the difference between Small Standard and Large Standard size tiers?

Small Standard items have a longest side of 15" or less, a median side of 12" or less, a shortest side of 0.75" or less, and weigh 16 oz or less. Items exceeding any of these dimensions fall into Large Standard, which carries higher fulfillment fees starting at $3.77 per unit.
