About FBA Calc: Helping Amazon Sellers Protect Their Margins

Welcome to FBA Calc. Running an Amazon business is hard enough without having to wrestle with complicated fee structures. We are a team of Amazon sellers and developers who were frustrated with the existing calculator tools on the market.

We built FBA Calc with one simple mission: To provide the fastest, most accurate, and privacy-focused profit calculators for sellers worldwide.

The Story Behind FBA Calc

Most tools were either too slow, full of annoying pop-up ads, or required an email sign-up just to do a simple calculation. Seller Central’s own calculator is accurate but clunky.

We wanted a tool that we could use ourselves—one that loads in milliseconds and works perfectly on mobile. Today, FBA Calc serves sellers across all major marketplaces:

Why Trust FBA Calc?

In a world of data harvesting, FBA Calc stands apart:

  • 🔒 Privacy First (Zero Data Storage): We know that your product data is your competitive advantage. FBA Calc runs entirely in your browser (Client-Side). We never store, save, or see the prices and costs you input. Your winning product ideas stay yours.
  • ⚡ Built for Speed: No bloated code, no sign-up walls, no loading screens. Just pure utility.
  • 🌍 Global Support: Whether you sell in the US, UK, Germany, Canada, Japan, or India, we have customized algorithms that account for local currencies and referral fee structures.

How Do We Keep FBA Calc Free?

Transparency is key. FBA Calc is 100% free to use. We do not sell your data, and we do not charge subscriptions.

Instead, we are supported by our partners. When you use our recommended tools (like Jungle Scout or Helium 10) through the links on our site, we may earn a small referral commission at no extra cost to you. This keeps our servers running and allows us to keep developing new features.
