FBA fee calculator (2026 rate card)

Your FBA fee is set by three things: size tier (from dimensions and weight), weight band, and — new for 2026 — your item's price band (<$10, $10–50, >$50). A 12-oz item under $10 fulfills for $3.13; the same item priced over $50 costs $4.21. On top of every table rate Amazon adds a 3.5% fuel and logistics surcharge that the published tables exclude. Enter your item below; the applied band is cited to Amazon's official rate card.

FBA charges ≈ $6.31 per unit to fulfill this item (fee $6.1 + 3.5% surcharge).

  • FBA fulfillment fee (large-standard, 2.33 lb shipping weight, $10–50 price band) Official fact$6.1
  • Fuel & logistics surcharge (3.5%) Official factAmazon's rate tables exclude this surcharge; it is billed on top since 2026-04-17.$0.21

Assumption: Dimensional weight (2.33 lb = L×W×H ÷ 139) exceeds unit weight and is used as the shipping weight.

Assumption: Non-peak rates (peak fees apply Oct 15 – Jan 14 and run higher).

  • Crossing a price band ($10 / $50) or a weight band moves the fee in steps, not smoothly — check the next band before repricing.
  • Dimensional weight punishes light-but-bulky items; smaller packaging directly cuts the fee.
  • Peak season (Oct 15 – Jan 14) uses a higher table.

The 2026 fee mechanics that actually move your cost

Price bands replaced the old uniform card in January 2026: items under $10 automatically get Low-Price FBA rates (about $0.86/unit lower on average), and crossing $50 adds another step. If your price hovers at $9.99 or $49.99, that's Amazon telling you where to price.

Dimensional weight (L×W×H ÷ 139) applies from the large-standard tier up — a light, boxy product is billed as if it were heavy. Then remember the two costs outside this calculator: monthly storage ($0.78/cu ft standard Jan–Sep, jumping to $2.40 Oct–Dec) and peak-season fulfillment fees from Oct 15 to Jan 14.

Common questions

Does this include referral fees?
No — the referral fee (typically 15%) is a selling fee charged whether you use FBA or not. Stack this fulfillment fee on top of it in the net margin calculator for the full picture.
What about large-bulky and extra-large items?
Their formulas aren't modeled here yet; the calculator says so instead of guessing. Check the official rate card linked below for those tiers.
