Amazon FBA Calculator: 2 Top Tools for 2026
Below you'll find detailed information about each option, including what makes them unique and their key benefits.
1. Shopify
While not an FBA profit tool itself, Shopify is directly relevant to sellers using an Amazon FBA calculator because many FBA sellers expand beyond Amazon to their own storefronts — and comparing FBA fees against Shopify's costs helps determine the most profitable fulfillment channel. Knowing your FBA margins through a calculator tells you whether Amazon or your own Shopify store yields better net profit per unit.
Key details:
- Plans start at $19–$25/month with a 3-day free trial
- No per-unit fulfillment fees like FBA — useful benchmark for cost comparison
- Best for: Entrepreneurs evaluating multichannel selling profitability
Amazon's own FBA Revenue Calculator is the most direct tool for estimating FBA costs, letting sellers input a product's selling price, cost of goods, and shipping to see net profit after Amazon's fulfillment and referral fees. It pulls live fee data directly from Amazon, making its estimates accurate for current fee structures.
What you get:
- Free to use inside Seller Central — no subscription needed
- Side-by-side comparison of FBA vs. merchant-fulfilled costs
- Real-time fee data tied to actual product ASINs
Final Words
Your best bet depends on whether you need a quick estimate or a detailed breakdown of every FBA fee. Factor in Amazon sales events when running your numbers, and pick the calculator that matches your workflow.
