Amazon FBA Storage Fees in 2026: How to Reduce Them

Build a storage forecast that can be reconciled to an invoice. The goal is to explain what each SKU costs to hold, not to apply one fee estimate to the entire catalog.

Separate the Charges

Monthly storage depends on occupied packaged volume and the applicable rate. Aging charges depend on how long units remain in the network. Utilization and low-inventory fees have their own eligibility calculations. A single current days-of-stock number does not determine all four.

Use the current rate schedule for the marketplace, product tier, season, and eligibility shown in your account. Avoid treating an old dollar rate as a 2026 quote.

Build a SKU-Level Cost Sheet

1. Export storage charges, inventory age, available/reserved quantities, and sales for a consistent period.
2. Record packaged dimensions and convert inches to cubic feet by dividing length × width × height by 1,728.
3. Separate actual charges from forecasts, including any expected age-tier changes.
4. Add upstream storage, receiving, prep, shipment handling, and freight before comparing logistics options.

Worked Volume Example

Turn the Forecast into a Financial Control

Keep forecast and actual charges in separate columns. Record the period, average quantity, packaged volume, applicable rate, and each surcharge. Explain variances as quantity, dimensions, eligibility, rate, timing, or unexplained differences.

Seller Scale recommends allocating shared costs consistently, then reviewing whether the allocation is suitable for the decision. A per-unit storage average can help a contribution model, while the cash bill still depends on inventory actually held. Do not mistake a projected allocation for an Amazon charge already incurred.
