Amazon Storage Fee & Long-Term Holding Cost Tracker

Leaving stagnant, slow-moving inventory inside Amazon’s fulfillment network is one of the fastest ways to drain an e-commerce brand’s liquid reserves.
Amazon systematically penalizes un-optimized sell-through rates by raising its base storage overhead charges, and once your stock crosses the critical 180 to 270-day window, severe long-term penalty multipliers kick in.
Our amazon long-term storage fee calculator maps out this progression, pinpointing the exact month your inventory turns into a net liability.
