total asset turnover. A financial ratio that indicates the effectiveness with which a firm's management uses its assets to generate sales. A relatively high ratio tends to reflect intensive use of assets. Total asset turnover is calculated by dividing the firm's annual sales by its total assets.

For example, a business that has net sales of $10,000,000 and total assets of $5,000,000 has a total asset turnover ratio of 2.0. It is best to plot the ratio on a trend line, to spot significant changes over time.
