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

There’s no universal target — healthy sell-through depends on the category, the season, your price architecture, and how long the product has been on the floor. A deep seasonal buy and a core replenishment item are judged on completely different curves. Instead of anchoring to a borrowed percentage, read sell-through against the window you’re measuring (weekly velocity versus to-date), against the same product’s own history, and against comparable items — then set your own targets from what consistently clears at full price in your store.

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. Vendee Pro mirrors POS sale events with their status, so returned line items are recorded with a returned status and netted out of the sales aggregates the Sell-Through and Best Sellers reports use — a high return rate quietly pulls your net sell-through down without you having to maintain a separate spreadsheet.

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.
