How this calculator works
Books and textbooks often have lower sale prices, so fixed closing and fulfillment costs can matter as much as the referral rate.
Use this calculator before listing used books, textbooks, rare books or book bundles through Amazon FBA.
Referral Fee = Sale Price × Referral Fee %
Fixed Fees = FBA Fulfillment + Storage + Closing Fee
Total Amazon Costs = Referral Fee + Fixed Fees + Extra Percentage Cost
Profit = Sale Price − Amazon Costs − Product Cost

Frequently Asked Questions
Why does the books calculator include a closing fee?
Books and media products can have a per-item closing fee. Keep the field editable so you can match your current Seller Central fee preview.
Can I use this for textbooks?
Yes. Enter the textbook sale price, buy cost and FBA fee. The formula works for used, new and collectible books.
Should I include storage fees for books?
Yes if inventory sits in FBA. Even small monthly storage costs matter on low-margin book inventory.
