Calculate the debt to assets ratio, a solvency ratio that measures the proportion of a company’s assets that are financed by debt.

This ratio, also known as the Debt Ratio, indicates the percentage of a company’s total assets that are funded by debt. It is a measure of a company’s financial leverage and indicates the extent to which a company relies on borrowed funds to finance its operations. A higher ratio implies a higher level of debt in the company’s capital structure, which could increase financial risk.

The formula is as follows:

\[\text{Debt to Assets Ratio} = \text{Total Debt} / \text{Total Assets}\]

Also known as: asset leverage, debt ratio.
