Sell-through rate
Sell-through rate is the percentage of available inventory sold during a period, calculated as (units sold ÷ units received or on hand) × 100. Retailers use it to judge how quickly a product or collection is moving, spot slow sellers early, and decide on reorders, markdowns, or promotions. It complements inventory turnover.
How it's calculated
Compare what you sold against what you brought in, over a defined period (often 30 days or a season):
Sell-through rate = (units sold ÷ units received or on hand) × 100
Example: receive 200 units, sell 150 in the month → 75% sell-through. Measure it per SKU, collection, or drop.
Why it matters
Sell-through tells you how fast a specific product or launch is moving relative to what you brought in — earlier and more granular than turnover. A high rate early signals you should reorder; a low rate flags a slow seller for markdown or promotion before it becomes dead stock. It's the go-to metric for Shopify merchants managing seasonal drops.
