Sell-through rate: meaning and how to calculate it
Sell-through tells you whether shoppers are buying what the channel has stocked.
Definition
Sell-throughSell-through is the quantity of a product sold by a retailer or distributor to end customers in a period. The sell-through rate expresses it as a percentage: units sold divided by units received, or by units available at the start of the period plus units received, multiplied by 100. It is a direct indicator of consumer demand in a channel.
How to use sell-through as a brand owner
Sell-through is calculated over a defined period, often weekly or monthly. If a store receives 200 units and sells 120 of them in four weeks, the four-week sell-through rate is 60 percent. Check which formula a partner uses, because some divide by stock received and some by stock available, and the results differ.
Retailers use the figure to decide reorders, facings and markdowns. Low sell-through early in a season leads to price cuts or a request for support from the supplier. High sell-through with frequent stock-outs suggests the product needs more space or bigger orders. For apparel and seasonal goods, sell-through is often the main measure of a buyer’s success. Read the rate alongside stock-outs and price cuts: a high figure achieved through deep discounts says little about demand at full price, and a low figure may simply reflect poor shelf placement.
Getting the data is the first hurdle. Large retailers may share it through supplier portals or reports; smaller ones may not track it per SKU. Marketplaces give you sales directly. Ask for sell-through reporting as part of the trade agreement, because without it you only see your own invoices, which is sell-in. Agree the format and frequency of the report up front. Otherwise you may get numbers too late to change an order.
Sell-through targets belong in the KPI set of the launch plan. For range decisions after launch, see assortment planning.

Frequently asked questions
What is a good sell-through rate?
It depends on the category, price and period. Fast-moving consumables and seasonal fashion are judged very differently. Compare with the retailer’s expectations for the category and with your own previous periods.
How do I calculate sell-through rate?
Divide the units sold in a period by the units received (or available) in that period and multiply by 100. Use the same formula as your trade partner so the numbers match.
