Debt / (shareholder equity + debt)
So if a company has $30 million in debt and $70 million in equity, its total capital is $100 million and its debt to capital ratio is 30%.
This ratio should be watched carefully, the higher the ratio the more the company is relying on borrowed money to pay for things. Which in turn means it is more likely that the company will get itself in trouble by borrowing too much money.
All industry groups are different so this ratio should be compared with others in the same industry group in order to decide if it is good or bad.
