Sell-Through Rate Calculator

Measure how fast a buy is moving relative to what you brought in.

Sell-through rate is the percentage of received stock you've sold over a period -- the fastest read on whether a buy is working. Enter units sold and units received.

How it works

Sell-through is the go-to metric for evaluating new products, seasonal buys, and promotions before you commit to a reorder. A high rate early is a signal to buy more; a low rate is a signal to mark down before the stock ages.

Skuwell tracks sell-through per SKU and channel, including FBA, so winners and losers surface fast enough to act on. Pair it with the FBA restock calculator for Amazon-specific planning.

Next step

Skuwell does this math for every SKU, automatically.

Reorder points, safety stock, turnover, and GMROI — computed live and turned into purchase orders. See it on a 30-minute walkthrough.
