Sell-through Rate

Sell-through measures the proportion of inventory sold during a given period. On Amazon, sell-through is defined as the ratio of units sold over the past 90 days to the average sellable units stored. Formula: Sell-Through = (Units Sold ÷ Units Received Or Available) × 100%

Why It Matters

  • •Sell-through is a key indicator of inventory health, demand alignment, and merchandising effectiveness.
  • •Low sell-through indicates overstock or weak demand.
  • •High sell-through reflects efficient inventory planning and strong product-market fit.
  • •It supports short-term operational decisions such as liquidation, replenishment pacing, and storage optimisation.

Connection to Capital

While sell-through is not a capital-efficiency metric, it influences capital needs indirectly through inventory levels. Low sell-through means inventory remains unsold for longer, increasing storage costs and delaying revenue.
