How This Works
Cubic feet per unit = (L × W × H) ÷ 1728
Storage fees are charged per cubic foot per month based on whether you are in Q4 (October–December) or off-peak (January–September). Standard-size and oversize items have different rates.
Aged inventory surcharges apply in addition to the base storage fee for items stored 271 days or longer. Remove slow inventory before these thresholds to avoid compounding costs.
