Return on equity can rise when debt increases because the business uses less owner capital to support a given asset base. If the earnings generated by the debt-funded assets exceed the financing cost on a comparable basis, the profit remaining for a smaller equity base can produce a higher percentage return. The same leverage can amplify losses when operating results weaken.
A higher ROE therefore does not automatically mean the business became more productive. Read it alongside operating returns, borrowing costs, cash flow and the amount of equity actually at risk. The source of the increase matters as much as the percentage.
Define return on equity clearly
A common formula is profit available to ordinary equity holders ÷ average ordinary equity × 100. Where relevant, preference dividends and other ownership features require appropriate treatment. Use the same reporting entity and period for profit and equity.
Average equity is commonly based on opening and closing balances, with more detailed averaging where significant contributions, distributions or restructuring make that simple average misleading. Book equity differs from the market value of the business and from the owner’s personal cash invested across all periods.
ICAI’s Schedule III guidance illustrates an ROE calculation using after-tax profit, preference-dividend adjustment where applicable and average shareholder equity. The actual definition used in a report should be explained and consistently applied.
Compare two financing structures
Consider an illustrative business requiring ₹100 lakh of assets and producing ₹20 lakh EBIT annually. For this example, assume an effective accounting tax charge equal to 25% of profit before tax in both cases. This is an arithmetic assumption, not a statement of the business’s tax rate or entitlement.
In an all-equity structure, debt is zero and equity ₹100 lakh. With no interest, profit before tax is ₹20 lakh, assumed tax ₹5 lakh and final profit ₹15 lakh. ROE is 15%, assuming stable equity throughout the period.
In a second structure, assets are funded by ₹60 lakh equity and ₹40 lakh debt charging 10% annual interest. Interest is ₹4 lakh. Profit before tax is ₹16 lakh, assumed tax ₹4 lakh and final profit ₹12 lakh. ROE is ₹12 ÷ ₹60 = 20%.
| Measure | All equity | Debt and equity |
|---|---|---|
| Assets | ₹100 lakh | ₹100 lakh |
| Debt | Nil | ₹40 lakh |
| Equity | ₹100 lakh | ₹60 lakh |
| EBIT | ₹20 lakh | ₹20 lakh |
| Interest | Nil | ₹4 lakh |
| Final profit under assumptions | ₹15 lakh | ₹12 lakh |
| ROE | 15% | 20% |
The debt-funded business earns less total net profit, yet reports higher ROE. Its operating earnings and assets are unchanged. The difference arises from financing and the smaller equity denominator.
Understand the downside amplification
Now suppose EBIT falls to ₹6 lakh while the financing structures remain unchanged. The all-equity business earns ₹4.5 lakh after the assumed tax charge, giving 4.5% ROE. The leveraged business pays ₹4 lakh interest, leaving ₹2 lakh before tax and ₹1.5 lakh after the assumed tax charge, giving 2.5% ROE.
Leverage now reduces the owner’s percentage return. If EBIT falls below interest, the leveraged business reports a pre-tax loss before considering other items. Any tax effect of a loss depends on actual rules and circumstances; do not assume an immediate cash tax benefit.
Interest and principal obligations do not disappear when sales weaken. Debt can turn a manageable trading slowdown into a funding problem if collections and repayment dates are poorly matched.
Use the DuPont relationship to locate the driver
For a simple consistent net-profit definition, ROE can be decomposed as net margin × asset turnover × equity multiplier. The equity multiplier is average assets divided by average equity. Increasing debt can increase this multiplier when it replaces equity in funding the same assets.
The relationship helps distinguish three explanations for a higher ROE: stronger profit per sales rupee, more sales from the assets or more assets supported by each equity rupee. The first two relate more directly to operating performance; the third reflects funding structure.
Keep all averages and reporting periods aligned. Mixing closing equity with average assets can break the clean identity or distort its interpretation. Also review other equity movements and unusual income that may inflate the numerator.
Check alternative reasons equity became smaller
Accumulated losses, drawings in a proprietorship, distributions and other permitted equity movements can reduce the denominator. A subsequent modest profit may then produce a high ROE on a depleted capital base. That is not necessarily evidence of a robust business.
If equity is very small, ROE becomes unstable. With zero equity, the ordinary ratio is undefined. Negative equity can produce misleading signs, so show profit, equity and debt in rupees and discuss the underlying financial position instead of ranking the ratio.
Asset write-downs and accounting corrections can also affect equity. Investigate the reconciliation before attributing a return change entirely to successful borrowing or management improvement.
Add repayment and operating evidence
Review EBIT margins, return on capital employed, interest coverage and operating cash. Prepare a schedule covering interest, principal, tax, stock needs and equipment spending. A company can show 20% ROE while lacking the cash to make its next instalment.
Check borrowing rates, reset terms, security and maturity concentration. Model a realistic sales decline or collection delay alongside a rate increase where relevant. The attractiveness of leverage depends on both the expected return and the business’s ability to withstand adverse outcomes.
A useful conclusion says why ROE increased. If the increase came mainly from replacing equity with debt, describe that funding effect and its risks. Owners can then judge whether the higher percentage return fairly compensates them for the additional financial commitments.
