Financial leverage shows how strongly a business relies on debt and fixed financing costs. No single ratio gives the full answer, so debt proportions, interest coverage and earnings sensitivity should be read together.
What is financial leverage?
Financial leverage arises when a company uses debt or other fixed-cost finance. Debt can increase returns to shareholders when operating performance is strong, but interest commitments also increase financial risk when earnings fall.
Main leverage measures
| Measure | Formula | What it indicates |
|---|---|---|
| Debt ratio | Debt ÷ Total capital | Share of total long-term capital financed by debt |
| Debt-to-equity ratio | Debt ÷ Equity | Debt financing relative to shareholders' funds |
| Interest coverage | EBIT ÷ Interest | Ability of operating profit to cover interest |
| Degree of financial leverage | % change in EPS ÷ % change in EBIT | Sensitivity of shareholder earnings to operating-profit changes |
Debt ratio
If debt is 400,000 and equity is 600,000, the debt ratio is 400,000 ÷ 1,000,000 = 40%. Book values may help with accounting analysis, while market values often provide a more current financing picture. State which basis is used.
Debt-to-equity ratio
Using the same figures, debt-to-equity is 400,000 ÷ 600,000 = 0.67. This means there is 0.67 of debt for each 1.00 of equity. Interpretation depends on industry stability, asset quality, loan terms and cash-flow predictability.
Interest coverage ratio
If EBIT is 180,000 and annual interest is 30,000, coverage is 6 times. A fall in EBIT to 75,000 would reduce coverage to 2.5 times even though the debt balance has not changed. Coverage therefore adds an earnings perspective to balance-sheet ratios.
Degree of financial leverage
At a particular output level, DFL can also be expressed as EBIT ÷ (EBIT − Interest), assuming a simple capital structure. With EBIT of 180,000 and interest of 30,000, DFL is 1.20. A 10% change in EBIT would produce approximately a 12% change in earnings available to ordinary shareholders before other complications.
Two-company comparison
| Measure | Company A | Company B | Initial reading |
|---|---|---|---|
| Debt ratio | 25% | 55% | B uses more debt |
| Debt-to-equity | 0.33 | 1.22 | B has more debt than equity |
| Interest coverage | 8.0× | 2.2× | A has the stronger interest buffer |
| DFL | 1.14 | 1.83 | B's shareholder earnings are more sensitive |
How managers should interpret leverage
- Compare several years, not one date.
- Compare like-for-like companies in the same industry.
- Review cash flow, loan maturity, security and covenants.
- Separate temporary borrowing from structural debt.
- Test a downside case for sales, EBIT and interest rates.
Limitations
Ratios can differ because of accounting policies, leases, off-balance-sheet commitments and market-value changes. High leverage is not automatically bad and low leverage is not automatically efficient. The question is whether expected cash flows can support financing commitments through changing conditions.
Frequently asked questions
Is debt-to-equity the same as debt ratio?
No. Debt-to-equity compares debt with equity, while debt ratio compares debt with total capital.
Is a higher interest-coverage ratio always better?
A larger buffer is generally safer, but excess conservatism may also indicate unused financing capacity. Context matters.
Why does DFL change?
DFL depends on the level of EBIT and fixed financing costs. As EBIT approaches interest expense, earnings sensitivity increases.
Should ratios use book or market values?
Use the basis suited to the decision and disclose it. Market values are generally more relevant for forward-looking cost-of-capital decisions.

The most commonly used measures of financial leverage are:
- Debt ratio.
L1 = D / (D+E) = D/V
Where D is value of debt, E is value of shareholders’ equity and V is value of total capital. D and E may be measured in terms of book value. The book value of equity is called net worth. Shareholder’s equity may be measured in terms of market value.
- Debt-equity ratio
L2 = D/E
- Interest coverage
L3 = EBIT/Interest
The first two measures of financial leverage can be expressed either in terms of book values or market values. The market value to financial leverage is theoretically more appropriate because market value reflects the current attitude of investors. But it is difficult to get reliable information on market values in practice. The market values of securities fluctuate quite frequently.
There is no difference between the first two measures of financial leverage in operational terms. They are related to each other in the following manner.
L1 = L2 / (1+L2) = (D/E) / (1+D)/E = D/V
L2 = L1 / (1-L1) = (D/V) / (1-D)/V = D/E
These relationships indicate that both these measures of financial leverage will rank companies in the same order. However, the first measure is more specific as its value will range between zeros to one. The value of the second measure may very from zero to any large number. The debt-equity ratio, as a measure of financial leverage, is more popular in practice. There is usually an accepted industry standard to which the company’s debt-equity ratio is compared. The company will be considered risky if its debt-equity ratio exceeds the industry standard. Financial institutions and banks also focus on debt-equity ratio in their lending decisions.
The first two measures of financial leverage are also measures of capital gearing. They are static in nature as they show the borrowing position of the company at a point of time. These measures, thus, fail to reflect the level of financial risk, which is inherent in the possible failure of the company to pay interest and repay debt.
The third measure of financial leverage, commonly known as coverage ratio, indicates the capacity of the company to meet fixed financial charges. The reciprocal of interest coverage, that is, interest divided by EBIT, is a measure of the firm’s income gearing. Again by comparing the company’s coverage ratio with an accepted industry standard, investors can get an idea of financial risk. However, this measure suffers from certain limitations. First, to determine the company’s ability to meet fixed financial obligations, it is the cash flow information, which is relevant, not the reported earnings. During recessionary economic decisions, there can be wide disparity between the earnings and the net cash flows generated from operations. Second, this ratio, when calculated on past earnings, does not provide any guide regarding the future risk ness of the company. Third, it is only a measure of short-term liquidity rather than of leverage.
