How to use

Why use this tool

The period basis stays explicit, so a short sales period is not silently presented as an annual result.

Before relying on the result

Use inventory and COGS on a consistent cost basis. Days are based on this period, not automatically annualised. Zero COGS gives no finite inventory days result.

Tool limitations

Use inventory and COGS on a consistent cost basis. Days are based on this period, not automatically annualised. Zero COGS gives no finite inventory days result.

Questions

What happens when cost of goods sold is zero?

A finite inventory days result is not available from zero sales cost. Review the selected period and underlying figures.

What should I check before using Inventory Turnover & Days Calculator?

Check Opening inventory value at cost, Closing inventory value at cost, Cost of goods sold in period and Period length. Use the exact units shown beside the controls and replace any example values with your own inputs.
