Debt-to-Capital Ratio Explained

The debt-to-capital ratio measures how much of a company’s capital structure is funded by debt. It is a key indicator of leverage and financial risk.

Debt-to-capital formula

Debt-to-Capital Ratio = Total debt ÷ (Total debt + Shareholders’ equity)

How to interpret it

• A higher ratio indicates greater reliance on debt financing.
• A lower ratio suggests a more equity-funded capital structure.
• Acceptable levels vary widely by sector. Utilities and telecom companies often carry more debt than technology companies.

Why it matters

High leverage can magnify returns when business conditions are favorable, but it can also increase risk during downturns or rising interest-rate environments.
