Free tools for Amazon FBA sellers

Check a product before you buy it. Both tools are free and the profit calculator needs no account at all.

Free Amazon FBA Calculator

Paste an ASIN or Amazon link. See the Buy Box price against its 30, 60 and 90 day averages, the sales rank trend, every Amazon fee including inbound placement by region, a two-year seasonality chart, and your profit once you enter your cost.

Look up a product

Amazon Profit, ROI and Break-Even Calculator

Type your selling price, product cost and fees and get contribution profit, margin, ROI and the break-even selling price. No lookup and nothing to sign up for.

Work out a margin

Guides that go with them

  • Amazon FBA fees in 2026, with real numbers
  • How to get ungated on Amazon
  • How to find and vet wholesale suppliers
  • How to choose an FBA prep center
  • Realistic Amazon wholesale profit margins

Checking one product at a time gets slow.

Apex runs the same checks on a supplier's whole price list and builds the purchase order for the products that clear your target.
