Sell-through rate compares units sold to units received or stocked over a period, which tells you whether a purchasing decision was sized correctly in a way raw unit sales cannot.

The sell-through rate formula

Sell-through rate = (units sold ÷ units received) × 100, for the period being measured. Some businesses calculate it against units received in that period; others against beginning-of-period on-hand plus receipts pick one convention and apply it consistently.

A very high sell-through rate (near or at 100%) usually means real demand exceeded what was ordered — unmet demand during a stockout never shows up in the sales count, so a consistently near-100% rate is a signal to increase the next order, not just a metric to celebrate.

Frequently asked questions

What is a good sell-through rate?
It varies by industry, but many retailers treat 40-80% as healthy within a selling period — high enough to show real demand without being so high it signals the order was too conservative.
How is sell-through rate different from inventory turnover?
Turnover measures how many times inventory is sold and replaced over a longer period (often a year). Sell-through rate is usually calculated over a shorter period against a specific batch or order, to check whether that one purchasing decision was sized right.
