Inventory Turnover Calculator

About this calculator

This calculator finds inventory turnover — cost of goods sold (COGS) divided by average inventory — and converts it into days on hand (365 / turnover), showing how many times stock is sold and replaced in a year. A higher ratio means inventory moves fast; a low ratio can signal overstocking or slow-moving goods.

Retail buyers, warehouse managers, and small business owners use it to benchmark against industry norms, spot dead stock before it ties up cash, and plan reorder timing. Accountants and analysts also use it when reviewing a company's working-capital efficiency.
