Sell-through rate is the percentage of inventory sold compared to the amount received during a specific period. It measures how quickly your products are selling relative to how much stock you're bringing in.

Sell-Through Rate = (Units Sold ÷ Units Received) × 100 Sell-through rate is one of the most important inventory health metrics. A high rate means products are moving quickly and your buying decisions are good. A low rate means stock is sitting and capital is tied up. The ideal rate varies by industry: fast fashion targets 80%+ monthly, while general retail aims for 60-80%. Tracking sell-through by SKU helps you identify winners to reorder and losers to discount or discontinue.
Sell-Through Rate = (Units Sold ÷ Units Received) × 100 You receive 100 units of a new product line. Over 30 days, you sell 65 units. Your sell-through rate is (65 ÷ 100) × 100 = 65%. This is healthy for most categories. If it was 25%, you'd want to investigate pricing, listing quality, or demand.
Sell-through rate tells you whether you're buying the right products in the right quantities. It directly impacts cash flow — fast sell-through means money comes back quickly for reinvestment. Low sell-through leads to dead stock, markdowns, and capital trapped in unsold goods.
