What is sell-through?

Sell-through is the share of received units that have sold over a given period. It tells you how quickly a style is moving relative to what you put into the channel, which signals whether to reorder, hold, or plan a markdown.

How do you calculate sell-through percentage?

Sell-through % = units sold ÷ units received × 100. For example, 350 units sold against 1,000 units received is a 35% sell-through, leaving 650 units remaining.

What is a good sell-through rate for apparel?

There is no universal target — it varies by category, season, price point, and where you are in the product lifecycle. A healthy week-four sell-through on a fashion drop looks very different from a basics replenishment program, and seasonal goods are read against their selling window. Compare sell-through to plan and to the same style last year rather than to a fixed number.

How do apparel teams use sell-through in-season?

Teams track sell-through by style, size, and channel against plan to decide where to chase, hold, or mark down. Strong early sell-through on broken sizes can trigger a reorder; slow sell-through past the planned curve flags the need for a markdown while there is still demand to capture.

Sell-through rate calculator

Sell-through rate is the share of received units that have sold — units sold ÷ units received × 100. It tells you how fast a style is selling and whether it needs a reorder or a markdown.

Sell-through % = units sold ÷ units received × 100.

// Reading the result · where spreadsheets break

Read sell-through against the planned selling curve, not a single benchmark. A 35% sell-through can be ahead of plan for a slow-burn basic and badly behind for a fashion drop that should clear in weeks. Break it out by size and channel — a strong overall number can hide broken size runs that warrant a chase, or a single channel dragging the rest down.

In a spreadsheet, sell-through is a snapshot pulled after the fact — units sold in one export, receipts in another, reconciled by hand a week or two later. By the time a slow style surfaces, the selling window has narrowed and markdown is often the only lever left. The value is in seeing it by style and size while there is still demand to chase or protect.
