About the metric
What the debt-to-equity ratio means
The debt-to-equity ratio compares interest-bearing debt with shareholders’ equity. It helps show how much debt financing a company uses relative to its accounting equity, but useful comparison levels vary by industry.
Calculation and source
How debt-to-equity is calculated
TickerStat calculates debt-to-equity as total interest-bearing debt divided by SEC-reported shareholders’ equity for the same balance-sheet date. Total liabilities are not treated as debt, and periods with non-positive equity are omitted. Fiscal periods can differ from calendar years, so exact period-end dates are included.
