How to Use an FBA Calculator to Make Better Sourcing Decisions

Amazon's FBA fees can make or break a product's profitability. Referral fees, fulfillment fees, and storage fees vary by category, size, and weight — and they can eat into your margins faster than you'd expect.

An FBA calculator takes the guesswork out of the equation. Enter any ASIN, and you'll see the exact fees Amazon charges, what you'll actually keep after those fees, and whether the product is worth selling at your cost.

What fees does Amazon charge FBA sellers?

Amazon charges three main types of fees for FBA sellers: referral fees (a percentage of the selling price, typically 8-15% depending on category), FBA fulfillment fees (based on item size and weight), and monthly storage fees (based on cubic feet of warehouse space your inventory uses). For large or heavy items, these fees can add up to 40-50% of the selling price.

Why 30-day averages matter

Amazon prices fluctuate constantly as sellers adjust their prices to compete for the Buy Box. Looking at the current price alone can be misleading — a product might be temporarily discounted or inflated. The 30-day average gives you a more reliable picture of what the product actually sells for over time, so your profit calculations are based on reality, not a snapshot.

Beyond fees: revenue per seller

Knowing the fees is step one. The real question is: how much can you actually make? ProfitGuru's FBA Calculator goes beyond fees to show you total revenue, total profit, and — crucially — revenue and profit divided by the number of active sellers. That context changes the sourcing decision.

Know your numbers before you source.
