Amazon Seller Fee Calculator
Amazon’s cut is a stack, not a single fee: a referral percentage that varies by category, an FBA fee that varies by size, and a closing fee. This calculator stacks them with rates you enter.
Planning estimate, not financial advice. All figures on this page are estimates or scenarios for planning purposes only, built from the numbers you enter. They are not financial, tax or legal advice, and no earnings are promised. Read the full financial disclaimer.
What this tool does
Enter the item price, the referral percentage for your category, the FBA fee for your item’s size tier, any closing fee, your item cost and shipping cost. The calculator shows each fee, the total Amazon keeps, the net per sale and the margin — so a price that looks profitable before fees stops surprising you after them.
The referral percentage is deliberately never hard-coded. Amazon’s referral rates differ by category, change without much notice, and a table copied from a roundup is how stale rates spread. Enter the rate from Amazon’s own fee schedule for your category, today.
Try it
Waiting. Enter the price, referral rate and FBA fee, then press Calculate.
How it works
The referral fee is the item price multiplied by the referral percentage for your category. The FBA fee is a flat figure for your item’s size and weight tier, and the closing fee is a flat figure where one applies. Total fees are the three added together, and the net per sale is the price minus fees minus item cost minus shipping cost.
Nothing here is a quoted Amazon rate. The referral percentage and the FBA fee are both entered by you from Amazon’s own fee schedule, because both vary by category and size — and both change.
Assumptions and limitations
Amazon’s fee schedule is the only source for its rates. This page quotes none of them as fact.
- Referral rates vary by category and change without much notice. Enter the rate from Amazon’s own fee schedule for your category, on the day you price the item.
- The FBA fee depends on the item’s size tier and weight. Enter the fee for your item’s tier — a small standard item and an oversize item are different fees entirely.
- The calculator covers referral, FBA and closing fees only. Storage fees, advertising, returns processing and account fees are separate and not modelled.
- Individual versus Professional selling plans change the per-item fees. Enter the figures for your own plan.
Worked example
Example (illustrative inputs, not a real listing). A 25 item, 15% referral rate (example category rate), 4 FBA fee, 8 item cost:
| Item | Figure |
|---|---|
| Referral fee (15% of 25) | 3.75 |
| FBA fee | 4.00 |
| Total Amazon fees | 7.75 |
| Net kept per sale (25 − 7.75 − 8) | 9.25 |
| Margin | 37.0% |
Frequently asked questions
Why is the referral fee not filled in for my category?
Because it varies by category and changes. A table copied from a roundup goes stale within months, and a wrong referral rate makes the whole calculation wrong. Amazon’s own fee schedule is the source — enter the rate for your category from it.
What is the FBA fee based on?
The item’s size tier and weight, as Amazon’s fulfilment schedule states it. Small standard items pay the least; large and oversize items pay far more. Enter the fee for your item’s tier.
What is the closing fee?
A flat per-sale fee that applies to some categories, such as media. It is 0 for most categories — enter 0 unless your category’s schedule states one.
Does this include storage fees?
No. Storage fees depend on how long inventory sits in a fulfilment centre and on the cubic volume, so they cannot be modelled per sale. Add a monthly storage figure to your costs separately.
