Frequently asked questions
What is an Amazon FBA calculator?
An Amazon FBA calculator estimates referral fees, FBA fulfillment, and net profit for one unit at a given sale price and product cost. This tool runs in your browser for quick pricing decisions on amazon.com.
Is this the same as an amazon fee calculator or profit calculator?
Yes. Sellers search for FBA calculator, amazon fee calculator, and amazon profit calculator for the same unit economics question. This page covers all of those intents with FBA and FBM modes.
Does this calculator store my data?
No. Calculations run entirely in your browser. Nothing you type is sent to BudgetBadger or saved.
What is the difference between FBA and FBM in this tool?
FBA mode includes an estimated FBA fulfillment fee by size tier plus optional inbound shipping to Amazon. FBM mode removes FBA fees and uses your shipping and packaging cost per unit instead.
Are these Amazon fees accurate?
Fee math is exact on the numbers you enter. Referral and FBA defaults are US estimates from a published rate card; Amazon changes fees by category, weight, and season. Peak and holiday FBA surcharges are not modeled here. Confirm in Seller Central or Amazon’s Revenue Calculator before major pricing decisions.
How is breakeven sale price calculated?
Breakeven is the sale price where net profit is zero after referral fee (a percent of price), fixed per-unit costs (COGS, fulfillment or shipping, PPC, and other costs you enter).
Is this Amazon’s official FBA Revenue Calculator?
No. This is an independent calculator from BudgetBadger. Amazon’s official tool is the FBA Revenue Calculator in Seller Central. We designed this for a fast per-unit view with FBM support and optional ad spend.
