What is a good inventory turnover ratio?

A higher ratio generally indicates strong sales or effective inventory management, but the ideal number varies by industry; compare your result to industry benchmarks for context.

How is inventory days calculated from the turnover ratio?

Inventory days are derived by dividing 365 (or the number of days in the period) by the inventory turnover ratio, showing the average number of days it takes to sell the entire stock.

Can this calculator be used for any type of business?

Yes, but the results are most meaningful when compared against industry averages; a ratio that is healthy for a clothing retailer may be low for a car manufacturer.

What does the beginning and ending inventory represent?

Beginning inventory is the value of stock at the start of the period, and ending inventory is the value remaining at the end; the difference, combined with cost of goods sold, determines how much was sold and replaced during the timeframe.
