Understanding Inventory Turnover
How we calculate. Inventory turns = cost of goods sold ÷ average inventory value. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Inventory Turnover case uses cogs / usage 4800000 and average inventory 800000. Enter the same figures below to reproduce the worked path.
What is Inventory Turnover?
A working-capital and velocity metric. Higher turns usually mean leaner stock relative to sales—context by category matters.
- Same cost basis for COGS and inventory
- Average inventory = typical (begin+end)/2
- Result is a ratio, not a percent
The Formula
Worked Example
Common Use Cases
- Working capital: stock velocity
- Category management: slow movers
- S&OP: turns vs service tradeoffs
Pro Tips
- Don’t mix retail and cost bases
- Watch seasonal averages
- Pair with days of supply (365 ÷ turns)
Limitations: Inventory Turnover results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.
FAQ
Is this a percentage?
No—turns are a ratio (times per period). Convert to days of inventory with 365 ÷ turns when helpful.
What if average inventory is 0?
Turns are undefined—enter positive average inventory.
