Frequently asked questions

What is a good inventory turnover?

It depends a lot on the industry: groceries turn many times a year, furniture or jewelry far fewer. Compare with your own past periods and similar businesses.

Why use cost of goods sold instead of sales?

Inventory is valued at cost, so using cost of goods sold compares like with like. Using sales would make turnover look higher than it is.
