Sell-through rate
Sell-through rate is the share of your available inventory that sells over a period, worked out as units sold ÷ units available × 100, and it gauges how fast stock moves.
A high sell-through rate means inventory is selling quickly relative to what you stocked, which supports Amazon's inventory-health metrics and keeps long-term storage fees down.
Too low and you risk aged-inventory surcharges. Too high without restocking and you risk selling out and losing rank.
Why it matters
Sell-through rate balances the twin risks of overstock fees and stockouts, both of which quietly erode FBA profitability.
