Sell-Through Rate Calculator
Work out your sell-through rate (STR) in seconds. Enter how many units you sold and how many are still in stock for the period, and this calculator shows the share of available inventory that actually sold.
How is sell-through rate calculated?
Sell-through rate is the percentage of available inventory you sold over a period. The formula is:
STR = units sold / (units sold + units still in stock) x 100
If you sold 120 units and 380 remain, your STR is 120 / 500, or 24 percent. A higher STR means inventory is converting quickly relative to what you are holding. There is no universal good number: compare a product against its own history and against similar products in your catalog.
We cover how to use STR for merchandising in more depth in our post on the sell-through rate attribute.
