Sell-Through Rate Calculator
Measure inventory sales velocity, sell-through percentage (STR), and estimate days remaining before stockout.
What is the Sell-Through Rate Calculator?
Sell-through rate calculation measures the percentage of delivered wholesale inventory successfully sold to end consumers within a specific retail sales period. It divides total units sold by starting inventory received from suppliers across the accounting cycle, multiplying by one hundred to derive percentage. This provides retail buyers and merchandisers with demand velocity metrics to adjust reorder volumes, execute promotional markdowns, and prevent dead inventory.
The Sell-Through Rate (STR) Calculator evaluates retail inventory velocity by measuring the percentage of received merchandise sold to end customers over a defined sales period.
