What is Sell-Through Rate?

The formula

Sell-Through Rate = Units Sold ÷ Units Received × 100

Measured over a window: a week, a month, a season, or at any point in a product’s life. If you received 100 units of a style on March 1 and sold 65 by March 31, your 30-day sell-through is 65%.

Why it matters

Sell-through is how a buyer learns. A high sell-through early in a product’s life is a reorder signal. A low sell-through after a fair window is a markdown signal. Over a season, sell-through patterns tell you which categories, vendors, and price points are earning their place in the assortment and which are not.

Weekly vs to-date sell-through

Weekly sell-through (this week’s units sold divided by units on hand at the start of the week) measures velocity. To-date sell-through (cumulative units sold since first receipt, divided by cumulative units received) measures total performance. Both matter. Weekly velocity catches acceleration or deceleration; to-date tells you whether the product earned the buy.

What a healthy sell-through looks like

Benchmarks vary wildly by category, season, and business model. Rough directional targets in traditional retail:

• Seasonal fashion apparel: 60-80% sell-through by end of the regular price window is typical for a healthy line. Above 80% often signals under-buying. Below 50% signals over-buying or a product that missed.
• Core, year-round replenishment items: 70-90% weekly sell-through would indicate a product running dry fast enough to warrant replenishment. Weekly sell-through is the better lens here.
• Footwear (core styles): 50-70% per month on in-season core. Seasonal styles behave more like fashion apparel.
• Accessories and giftable categories: 40-60% over a shorter window, with holiday spikes pulling the target higher in Q4.

These numbers are starting points, not gospel. Your category mix, price architecture, and brand position change the targets.

Sell-through by variant

Total-product sell-through hides what you need to see. The green medium might be 95% sell-through while the black XXL is 15%. Reordering the product blindly ignores the variant-level truth. Vendee Pro’s reports show sell-through at the variant level, so reorders follow the actual demand signal.

How to use sell-through for reorders

• High sell-through + strong weekly velocity + weeks of season left: reorder, if OTB allows.
• High sell-through + low weekly velocity (running out but not selling fast): verify the SKU is on display in the right locations before reordering.
• Low sell-through + weeks of season left: evaluate for markdown, move to a better-performing location, or feature in marketing.
• Low sell-through + end of season approaching: plan end-of-season markdowns or markdown-plus-transfer to clearance-friendly locations.

Returns and sell-through

Returns reduce net units sold. Reports should show gross and net side-by-side so you can see whether a high gross sell-through is being eroded by a high return rate. Vendee Pro shows both.

Sell-through and dead stock

SKUs with low sell-through that also show no recent movement are drifting toward dead stock. Dead stock reports pull the list automatically, so the markdown decision isn’t one you have to remember to make.
