Why a Calculator Beats Guesswork
Referral fees change by category, fulfilment rates rise with weight breaks, and storage climbs during peak season. Trying to run those numbers in your head is risky. A calculator pulls the latest schedules published in Amazon’s fee FAQ and shows the exact margin you will keep at your chosen price.
Getting a Fast Estimate
- Measure the product in its ready-to-ship package.
- Type dimensions, weight, and price into the calculator.
- Compare the projected profit for FBA versus FBM.
- Tweak price until the margin meets your target.
