Amazon FBA storage fee calculator
Storage is thin volume but expensive when you leave units idle. This page surfaces a storage/other dollar field next to referral and fulfillment so monthly or aged inventory estimates hit the stack. We do not pull Amazon storage invoices - you enter the dollars.
Estimate only — not your seller payout.
When to use — and when not to
When to use
Aged inventory cleanup math; peak vs off-peak storage guess; storage fee SERP with high CPC.
When not to
Fulfillment-only → amazon-fulfillment-fee-calculator. No storage number yet → fba-fee-calculator.
Assumptions
Storage/other field defaults to a small stub you can clear; referral + fulfillment still apply.
Worked examples
$26 price, $3.5 fulfill, $2.00 storage
Storage adds a clear third fee line
Storage $0 vs $4 on same SKU
Shows when idle stock kills margin
How it calculates
fees = referral + fulfillment + storage_other + ads
Stack the fee lines, then read payout (and profit when costs are entered).
- Enter the sale price and any buyer-paid shipping that applies.
- Confirm or override the rate defaults for your case.
- Add ads, storage, or costs only when they apply.
- Read the fee stack - estimate only, not the marketplace payout screen.
Common traps
- Monthly storage ≠ fulfillment.
- Peak months need your own higher number.
- Aged inventory surcharges are manual.

FAQ
No. Enter storage dollars you already estimated from Amazon reports or a peak-month guess. We stack that line with referral and fulfillment.
