Definition – What is sell-through rate?

Sell-Through Rate is a measurement of how much inventory is sold in a period of time. It is typically measured over a month, quarter, or year.

A sell-through rate of 100% over a month means that the entire inventory is sold over 30 days. A sell-through rate of more than 100% means that more than the value of inventory is sold each month.

Formula – How to calculate sell-through rate

Sell-Through Rate = Units Sold / Inventory at the Begining of the Period x 100%


A business starts the period with 40 units in stock. They sell 300 units during the period.

Sell-Through Rate = (300 / 40) x 100% = 7.5 x 100% = 750%

Therefore, this businesses’ sell-through rate is 750%.
