Worked example

$600,000 of annual COGS and $75,000 average inventory produces 8.0x turnover and about 45.6 inventory days.

Methodology

How this calculation works

Beginning and ending inventory are averaged, COGS is divided by that balance, and period days are divided by turnover.

How to interpret the result

Higher turnover may release cash but can also indicate inadequate stock. Compare with product lead times, stockouts, write-offs, and appropriate industry peers.

Limitations

Results are educational planning estimates. They do not include every tax, legal, accounting, financing, or business-specific consideration and are not professional advice.
