Sell-Through Rate Calculator
Sell-through rate
73.0%
Share of received stock that has sold during this period.
How to use this number
Calculate this per SKU or per product line rather than for your whole store — a healthy blended average can still hide a slow-moving batch that's quietly turning into dead stock.
Watch the trend across consecutive periods more than any single number. A sell-through rate that's declining period over period on the same SKU is an earlier warning sign than waiting for the item to show up on a dead stock report.
Frequently Asked Questions
What is the sell-through rate formula?
Sell-Through Rate % = (Units Sold ÷ Units Received) × 100, measured over a set period (commonly a month or a season). It shows what share of the stock you received has actually sold.
What is a good sell-through rate?
It varies heavily by category and season, but a commonly cited healthy range for retail is 40-80% per month. Below that on a specific SKU usually means overstock or weak demand; consistently near 100% can mean you are understocking and leaving sales on the table.
How is sell-through rate different from inventory turnover?
Sell-through rate looks at one batch or period: what share of what you received has sold. Inventory turnover looks at your whole catalog over a year: how many times average inventory value is sold and replaced. Both matter, but sell-through is the sharper tool for judging one buy or one SKU.
Does this calculator save my numbers?
No. This is a client-side calculation only — nothing is sent to a server or saved. Refreshing the page resets it to the defaults.
