Result:

Inventory Turnover is a central indicator of capital efficiency. Higher turnover means capital is tied up in inventory for less time.

Good sign

An inventory turnover above industry average indicates efficient inventory management and accurate demand forecasting.

Warning sign

Low inventory turnover may indicate overstock, obsolete products or weak demand - tied-up capital that isn't working.

Always consider inventory turnover industry-specifically. Food naturally has higher turnover than furniture.

What does Inventory Turnover mean for your online store?

Inventory Turnover is one of the most important operations metrics in e-commerce. It shows how efficiently your capital in the form of inventory is working. Higher inventory turnover means less tied-up capital and lower storage costs.

Why Inventory Turnover matters

Every item sitting in your warehouse ties up capital - capital that cannot be invested elsewhere. Add storage costs, the risk of value loss through trends or obsolescence, and capital carrying costs.

An inventory of $500,000 at 4x turnover ties up $125,000 in capital on average. At 8x turnover, it would be only $62,500 - $62,500 more for growth investments.

How to optimize your Inventory Turnover

There are proven strategies to sustainably improve inventory turnover:

  1. 1 Demand Forecasting: Use historical data, trends and seasonality for precise sales forecasts. The better the forecast, the less overstock.
  2. 2 ABC Analysis: Classify your products by revenue contribution. A-items (top 20%) deserve more attention in inventory optimization.
  3. 3 Dynamic Reorder Points: Adjust safety stock levels to current lead times and sales velocity. Static values lead to overstock.
  4. 4 Active Inventory Cleanup: Identify slow movers early and reduce them through promotions, bundles or delisting.

Inventory Turnover in context with other KPIs

Inventory Turnover is directly related to Out-of-Stock Rate and Return Rate. Overly aggressive inventory management may increase turnover but can also lead to more out-of-stocks and lost sales.

Find the optimal balance through continuous monitoring of both metrics. High inventory turnover with low OOS rate is the goal - this requires excellent demand planning.
