To calculate Amazon FBA fees for a wholesale product, add the referral fee (a percentage of the selling price) and the FBA fulfillment fee (based on size and weight), then allow for storage, inbound shipping and any extra fees. Amazon’s free revenue calculator gives the main two in seconds.
Quick answer: Look up the product in Amazon’s FBA Revenue Calculator, enter your selling price, and it shows the referral and fulfillment fees. Then add inbound shipping, prep and expected storage to get your real cost per unit.
The Main Amazon Fees for Wholesale Sellers
| Fee | How it is charged |
|---|---|
| Referral fee | A percentage of the selling price, set by category |
| FBA fulfillment fee | Per unit, by size tier, weight and price band |
| Monthly storage fee | Per cubic foot, higher from October to December |
| Inbound placement fee | Per unit, depends on how your shipment is split across warehouses |
| Low-inventory-level fee | Per unit, when your stock runs low compared with sales |
| Aged inventory surcharge | When stock sits too long in Amazon’s warehouses |
Amazon updates these fees regularly. In 2026 it also added a fuel and logistics surcharge to FBA fees. Always check Amazon’s current fee pages before you rely on a number.
Referral Fee
Most categories pay a referral fee of around 15% of the selling price. Some categories, including parts of beauty, health and grocery, pay a lower rate on lower-priced items. Check the rate for your exact category.
FBA Fulfillment Fee
This covers picking, packing and shipping each order. It depends on the product’s size tier, its shipping weight and its price. Heavier and bulkier products cost more, which is why small, light products are popular for wholesale.
Storage and Other Fees
Storage is charged on the space your stock takes up each month. Order quantities you can sell in a reasonable time to keep storage and aged-inventory costs down. See how to budget for your first wholesale order.

Fees You Can Avoid
- Prep problems: Amazon no longer preps or labels units for you in the US, so units that arrive without labels or the right packaging risk delays and receiving problems. Learn how to avoid unplanned prep fees.
- Low-inventory fees: reorder before you run out.
- Aged inventory surcharges: do not over-order slow sellers.
Our team adds FNSKU labels, poly-bags where needed and ships cases straight to Amazon FBA, so your units arrive ready to sell.

Frequently Asked Questions
Is the revenue calculator accurate?
It uses Amazon’s current fee rates for the product’s stored size and weight. It is the best starting point, but it does not include your inbound shipping or prep costs.
Do FBA fees change during the year?
Yes. Storage costs more from October to December, and Amazon often applies peak fulfillment rates in the holiday season.
Are there monthly account fees too?
A Professional selling plan has a monthly subscription. Spread it across your units if you want a full cost picture.
