Free Amazon FBA Storage Fee Calculator
Estimate monthly FBA storage cost, including peak-season rates.
Amazon roughly triples storage rates during peak season (October through December) to encourage sellers to manage inventory tightly ahead of the holiday rush. Factoring this into your inventory planning avoids an unpleasant storage bill surprise in Q4.
Worked Example
Example: 1,000 units at 0.05 cubic ft each = 50 cubic ft, standard size, non-peak month. Storage fee ≈ 50 × $0.78 = $39.00/month. The same inventory in peak season (Oct-Dec) ≈ 50 × $2.40 = $120.00/month.
Formula
Storage Fee = Total Cubic Feet × Rate per Cubic Foot
Non-peak: $0.78/ft³ (standard), $0.56/ft³ (oversize). Peak (Oct-Dec): $2.40/ft³ (standard), $0.98/ft³ (oversize).
