Sell-Through Rate

Sell-through rate is the percentage of the inventory you shipped that actually sold in a given period. It is the number a retail buyer trusts more than any pitch, because it answers the only question they care about: does this product move fast enough to earn its shelf space? A strong sell-through gets you reordered. A weak one gets you marked down and dropped.

The formula

Sell-through rate = (units sold ÷ units received) × 100, measured over a set period.

If a store received 1,000 units and sold 800 in the period, the sell-through rate is 80%. Sell 300 of that 1,000 and it is 30%, which tells the buyer something went wrong with the product, the price, or the demand forecast.

Always tie the number to a time frame. A 60% sell-through in one week means something very different from 60% over a season.

What counts as good

There is no single universal target, but the widely used benchmarks are:

• 60 to 80%: healthy. The product is selling at a pace that justifies the inventory.
• Above 80%: strong demand. Very good, though it can also mean you understocked and left sales on the table.
• Below 40%: weak. The product is overstocked or underperforming, and markdowns are coming.

For short-life or limited drops, like a seasonal fashion release, aim for above 80% within the launch window, because you cannot easily restock and every unsold unit becomes a markdown.

Why it matters to your brand

• It drives reorders. Retailers decide whether to buy again, expand your doors, or drop you based on sell-through. It is your report card in every store.
• It is your best pitch to the next buyer. Strong sell-through at one retailer is the hardest evidence you can bring to pitch the next one.
• It protects your margin. Low sell-through leads to markdowns and markdown money, which come out of your pocket. See wholesale pricing and terms.

Frequently Asked Questions

What is a good sell-through rate?

A sell-through rate of 60 to 80% over its period is generally considered healthy. Above 80% signals strong demand, and below 40% signals the product is overstocked or underperforming. For limited or seasonal drops, aim above 80% within the launch window, since unsold units quickly become markdowns.

How do you calculate sell-through rate?

Divide the units sold by the units received, then multiply by 100, over a set time period. If a store received 1,000 units and sold 800, the sell-through rate is 80%. Always attach a time frame, because the same percentage means different things over a week versus a season.

Why do retail buyers care about sell-through rate?

Because it measures how fast a product earns its shelf space. Buyers use sell-through to decide whether to reorder, expand, or drop a brand. A strong rate is also the most persuasive proof you can bring when pitching the next retailer, since it shows the product already sells.
