Sell-through rate measures what percentage of your available inventory has been sold within a specific time period. It is calculated as units sold divided by total units available. A high sell-through rate indicates strong demand; a low rate may indicate overstocking or pricing that is too high relative to the market.
Sell-through rate is an important signal for inventory-sensitive pricing rules. As sell-through rate falls, a repricing rule might lower prices to accelerate movement. As inventory depletes and sell-through accelerates, a rule might raise prices to protect remaining stock margin.
