The debt ratio measures the proportion of a company's total assets that are financed by debt (total liabilities). It is calculated by dividing total liabilities by total assets. The result is a number between 0 and 1, where 0 means no liabilities at all and 1 means the company's assets are entirely funded by debt with no equity cushion.
The debt ratio is a simpler and more bounded alternative to the debt-to-equity ratio. Because it uses total assets in the denominator rather than equity, the debt ratio cannot become negative or undefined when a company has negative equity, making it usable across all companies regardless of capital structure.
A debt ratio of 0.5 means half of the company's assets are financed by liabilities and half by equity. A ratio above 0.6 is generally considered moderately leveraged, and above 0.8 is highly leveraged. As with all leverage metrics, the appropriate level depends on the industry — capital-intensive industries with stable cash flows support higher ratios than cyclical businesses.
