Amazon Seller Fees Calculator

This Amazon seller fees calculator helps you estimate how much of every order is eaten by referral fees, fulfillment fees, and per-unit charges, and how much you actually keep as profit. It’s designed for private label brands, resellers, arbitrage sellers, and agencies who want a quick, realistic gut check on margins before sending inventory into FBA or listing new SKUs on Amazon.

1. Start with what the buyer pays on Amazon

In the first box, enter the total sales price in USD — the amount the buyer pays on Amazon for one unit, including item price and any shipping you charge. The calculator uses this as the base for the blended Amazon fee percentage, similar to how referral fees are calculated on the total sales price in official fee schedules. Once you hit “Calculate”, you’ll see estimated Amazon fees and net proceeds per sale.

2. Add your target net to protect your margin

If you know how much you need to keep after platform costs and fulfillment, use the “You want to keep after Amazon fees” input. This is your post-fee target per unit, before product cost and overhead. When you enter a target net, the tool works backwards to show the minimum Amazon sales price required to hit that goal, along with the fees and effective fee percentage at that price point.

3. Plug in a realistic blended Amazon fee rate

Amazon fee structures change by category, marketplace, and fulfillment method. To keep the calculator fast and flexible, the fee section uses a single blended percentage plus a fixed per-unit fee. You can:

• Use the default 15% + $1.80 as a rough average for many standard FBA items.
• Overwrite the percentage with the exact referral fee for your category and marketplace.
• Adjust the fixed fee to approximate FBA pick-pack, closing fees, or FBM shipping/handling costs per unit.

4. Read the breakdown to see true per-unit profit

The results card shows a headline number — either your net proceeds per sale or the minimum buyer price needed to reach your target net. Under that, you get a detailed breakdown: buyer pays, total Amazon fees, net to you, and the effective fee rate as a percentage of the sale. This makes it easy to sanity-check whether a product still works on Amazon once fees are layered on top of product cost, prep, and shipping.

5. Use it while sourcing, pricing, and planning FBA shipments

Use this Amazon fee calculator when you’re sourcing new products, negotiating with suppliers, deciding between FBA vs FBM, or adjusting your prices ahead of fee changes. Run a few “what if” scenarios: increase your price, tweak your blended fee, or raise your target net to see how much room you have left for ads and coupons. The Copy summary button gives you a clean, text-only breakdown you can paste into spreadsheets, sourcing docs, or Slack threads with your team.

Keep in mind this tool focuses on core per-unit selling fees only. It does not model storage surcharges, low-inventory fees, long-term storage, advertising spend, or multi-channel fulfillment. For final numbers, always refer to Amazon’s official fee schedule and revenue calculators inside Seller Central and check your latest payout reports.

Behind the scenes, this calculator models Amazon as a simple combination of a percentage fee on the sales price and a fixed per-unit fee. Let G be the total amount the buyer pays in USD on Amazon (item price plus shipping), r be your blended fee percentage as a decimal (for example 0.15 for 15%), and f be the fixed fee per unit in USD (for example 1.80).

The total Amazon fees on a single unit are:

Amazon fees = G × r + f

The amount you receive after those fees is:

Net proceeds = G − (G × r + f)

When you enter a target net amount instead, the calculator rearranges the equation to solve for the sales price that leaves that net after Amazon takes its cut. If N is the net you want to keep in USD, the minimum Amazon price you need to charge is:

Required price = (N + f) ÷ (1 − r)

The effective fee percentage displayed in the results is simply:

Effective fee % = Amazon fees ÷ sales price × 100

That number gives you an apples-to-apples way to compare Amazon to other marketplaces, DTC storefronts, and payment processors, and to see how changes in your price or fee assumptions move your net margin per sale.
