6.6What is the Debt-to-Equity ratio?

1What is it?

Debt-to-Equity (D/E) compares how much the company has borrowed with how much the owners have put in.

2Why does it exist?

Debt must be repaid with interest whether business is good or bad. Too much debt can sink a company in a downturn.

3Real-life example

A family with ₹10 lakh of savings and a ₹30 lakh home loan has D/E = 3. A job loss would hurt them much more than a family with no loan.

High value means…

More financial risk; interest eats profits; danger in downturns.

Low value means…

Conservative finances; more resilience.

Is high or low good?

Lower is generally safer (below 1 for most non-financial companies). Banks naturally have high leverage; judge them differently.

5Calculation
D/E = Total debt ÷ Shareholders’ equity
  1. Debt = ₹4,000 cr; equity = ₹8,000 cr.
  2. D/E = 4,000 ÷ 8,000 = 0.5.
₹0.50 of debt for every ₹1 of equity.
6Risks
  • Varies a lot by industry (power, infra are debt-heavy by nature).
  • Doesn’t show when debt is due.
7Practical use

Always compare a ratio with (1) the company’s own history and (2) other companies in the same industry. A single number on its own means little.

8Quick revision
  • D/E = debt ÷ equity.
  • Below 1 is comfortable for most businesses.
  • Don’t apply to banks.
