Use this tool

Prepare the input and run the tool

Enter price, landed cost, package details, category, ads, storage, discounts, and the current all-in Seller Central FBA fee. Result: Review the current scenario's profit, margin, ROI, cost breakdown, and downloadable CSV.

All tools
Estimate onlyThe tool requires the current all-in FBA fee from Seller Central because Amazon says fulfillment costs depend on product price, weight, dimensions, and program rules. It does not predict a break-even or target price because a price change can also change Amazon's fulfillment and referral fees. Recheck Seller Central after changing price.

Enter one Amazon FBA product scenario and get a live profit, margin, ROI, and fee breakdown for US marketplace planning.

Amazon says fulfillment costs depend on a product's price, weight, dimensions, and program rules. This calculator therefore requires the current all-in FBA fee from Seller Central instead of guessing it from a generic rate table. The value is treated as final, so the tool will not add the fuel and logistics surcharge twice.

Artifacts you can produce

  • Amazon FBA planning scenario CSV

What this tool does not do

  • The tool requires the current all-in FBA fee from Seller Central because Amazon says fulfillment costs depend on product price, weight, dimensions, and program rules.
  • It does not predict a break-even or target price because a price change can also change Amazon's fulfillment and referral fees. Recheck Seller Central after changing price.
  • It does not fully model Low-Price FBA, apparel variants, dangerous goods, peak rates, inbound placement, aged inventory, returns processing, storage utilization, or every category exception.
  • Amazon can change fees and product classifications. Refresh the Seller Central fee before relying on a saved scenario; the tool will not add a surcharge again to that all-in value.

Formula / how it works

  3. 3Add storage, advertising, discount, return, and closing-fee assumptions without adding a second fuel surcharge.

Common errors and fixes

FBA fee looks too low or too high

The package size, shipping weight, category, or manual fulfillment fee can change the model more than the sale price.

Confirm the packed dimensions and weight, choose the closest referral category, and use the manual FBA fee field when Seller Central gives you a known fee.

ROI changes sharply after ads or returns

Small products can look profitable until per-unit ad spend, storage, discounts, and return allowance are included.

Enter those costs as per-unit values and review the current scenario's profit, margin, and ROI before buying stock. Refresh the Seller Central fee before testing a different selling price.

CSV export does not match the calculator screen

The export reflects the current form state only, so stale browser fields or blank optional costs can make the row look incomplete.

Recalculate after changing inputs, then download the CSV again and keep one export per product scenario.
