Amazon FBA Profit Calculator

Amazon FBA sellers don’t pay one fee — they pay a stack of them. Total Amazon fees commonly consume 30% to 45%of a product’s selling price once you add it all up. Here is what Amazon charges on the US marketplace in 2026:

• Referral fee— Amazon’s commission on every sale, charged on the total sales price (item price plus any delivery or gift wrap, excluding tax). Most categories pay 15% with a $0.30 minimum. Consumer electronics is 8%; personal computers is 6%; clothing is 17%; jewelry runs up to 20%. A few categories tier the rate by price — beauty and health pay 8% under $10 and 15% over, grocery pays 8% under $15 and 15% over.
• FBA fulfillment fee (updated 15 Jan 2026) — Amazon’s pick-pack-ship cost per unit, based on size tier and weight. A small-standard item runs about $3.30; a large-standard ≤1 lb about $4.98; a small oversize about $8.74; and the largest bulky oversize products can hit about $75.86. Typical small/standard items land in the $3.00 – $6.50 range.
• Monthly storage fee — per cubic foot, per month, and seasonal. Standard-size inventory pays about $0.75/ft³ from January to September and about $2.40/ft³ in October, November and December. Inventory sitting over 365 days adds a long-term storage surcharge of about $6.90/ft³.
• Professional Selling Plan — $39.99/month, flat. If you sell 50+ units a month it’s effectively under $0.80 per unit; below that, switch to the Individual plan ($0.99 per item).
• Inbound placement fee — what Amazon charges to receive your inventory into its fulfillment network. Typically $0.21 – $1.58 per unit depending on how you split shipments across fulfillment centers.
• Other fees — a returns processing fee in high-return categories (apparel, shoes), a low inventory level fee, removal/disposal fees, and a 2026 fuel surcharge that can move fulfillment fees by a few cents up or down. None large individually, but worth knowing.

Compared to Etsy, Amazon’s structure is more aggressive but more predictable: every product in the same category and size tier pays the same fees, so once you know your numbers, scaling is straightforward. Always verify the latest fee for your specific category and size tier in Seller Central before committing to a price.

Net profit per unit is straightforward arithmetic:

Profit = Sale price − Referral fee − FBA fulfillment fee − Storage fee − Cost per unit

But experienced FBA sellers track two metrics, not one:

• Profit margin = Profit ÷ Revenue. Tells you how efficient each sale is.
• ROI (return on investment) = Profit ÷ Cost per unit. Tells you how hard your inventory cash is working.

The same 30% margin product can have anywhere from a 50% to a 250% ROI depending on what you paid for the unit. Most experienced FBA sellers source against 30%+ margin AND 50%+ ROI — anything less leaves no buffer for advertising, returns or the inevitable Q4 storage spike.

That’s a strong sourcing target. Cost the same unit at $12 instead of $5 and ROI drops to about 47% — same margin, much weaker business. This is why FBA sellers chase low COGS as hard as they chase high prices.

The calculator above mirrors how Amazon actually charges FBA sellers, so the numbers it shows match what lands in your Seller Central account. Use it in three quick steps:

1. Enter your sale price and cost per unit. Sale price is what the buyer pays on Amazon. Cost per unit is your manufacturing or wholesale cost plus inbound shipping to Amazon’s warehouse, per unit.
2. Pick a category preset and a size tier. The category preset sets the referral fee % to one of the common rates — you can edit the percentage directly for any category (including tiered categories like Beauty under/over $10). The size tier preset sets the FBA fulfillment fee — edit the dollar amount directly to match an exact figure from Seller Central.
3. Open Advanced for storage and Pro Plan. Add an estimated storage cost per unit, allocate the $39.99 Professional Plan across your expected monthly orders, and add an inbound placement fee. Optional but recommended for an accurate net profit.
