Sell-Through Rate Calculator

Calculate sell-through rate

Sell-through rate measures the percentage of received inventory that has sold during a given period, usually a month. It is calculated by dividing the number of units sold by the number of units received and multiplying by one hundred. Selling three hundred fifty of five hundred units received gives a sell-through rate of seventy percent. The metric shows how quickly a product is moving relative to how much was brought in, which helps with reordering and markdown decisions.

Unlike inventory turnover, which looks at the whole inventory, sell-through focuses on a specific delivery or season.

Using sell-through

Retailers and ecommerce sellers use sell-through rate to judge demand and manage stock. A high rate signals strong demand and may mean you should reorder or raise prices, while a low rate suggests overstocking or weak demand, pointing toward promotions or markdowns to clear inventory. Fashion and seasonal businesses watch it closely because unsold stock loses value quickly.

What counts as a healthy rate depends on the product and sales cycle; a monthly sell-through around sixty to eighty percent is often considered good for many retailers. Track it by product and over time for the clearest signal. All calculation happens locally in your browser.
