Cost of Debt vs Cost of Equity: Comparison, Calculation & Real-World Examples
Understanding the difference between cost of debt and cost of equity is essential for mastering financial management. These concepts help students analyze how companies finance their operations, which is a common question in school exams, competitive exams, and daily business analysis. Both costs are crucial for making smart investment and financing decisions.
| Basis of Comparison | Cost of Debt | Cost of Equity |
|---|---|---|
| Definition | Effective interest rate paid on borrowed funds | Return expected by shareholders for investing in equity |
| Source of Capital | Loans, bonds, debentures | Share capital, retained earnings |
| Tax Benefit | Interest is tax-deductible | No tax deduction available |
| Risk for Investor | Low (debt holders have priority) | High (shareholders are last to be paid) |
| Ownership Dilution | No dilution | Dilutes ownership |
| Cost Level | Usually cheaper | Usually more expensive |
Difference Between Cost of Debt and Cost of Equity
The cost of debt and cost of equity are components of capital structure analysis. The cost of debt refers to the total effective interest a company pays on its borrowings. The cost of equity is the return shareholders expect for their investment and risk in the business. Knowing both is vital for financial strategies and exam preparation.
Meaning of Cost of Debt
The cost of debt is the actual interest rate a company pays on its loans, debentures, or other borrowings. It is usually calculated as the after-tax interest expense, since interest payments can be deducted from taxable income. This makes debt a less expensive source of finance. Cost of debt directly affects overall financing decisions and business profitability. You can learn more about Redemption of Debentures for deeper insight into debt capital management.
Meaning of Cost of Equity
The cost of equity is the expected return by shareholders for investing in company shares. Unlike debt, dividends paid to shareholders are not fixed or tax-deductible. This cost includes the risk of investing, as shareholders are the last to claim earnings if a company faces liquidation. The cost of equity is essential for making financing decisions and evaluating company performance, as discussed in Return on Investment and Return on Equity.
How to Calculate Cost of Debt and Cost of Equity
- Cost of Debt (Kd): After-tax interest expense divided by total debt.
Formula: Kd = Interest Expense × (1 – Tax Rate) / Total Debt - Cost of Equity (Ke): Calculated using models like the Dividend Discount Model or Capital Asset Pricing Model (CAPM).
Formula (Gordon’s Model): Ke = Dividend per Share / Market Price + Growth Rate
Why Debt is Usually Cheaper Than Equity
- Interest on debt is tax-deductible, reducing net cost.
- Debt holders take less risk compared to shareholders.
- Shareholders expect higher returns for higher risk.
This is why, in most financial analysis and cases, the cost of debt is below the cost of equity. Vedantu guides students to quickly identify such differences during exam preparation.
Real-World Example
Suppose a company has a loan of ₹10,00,000 at 10% interest, and pays ₹1,00,000 in interest yearly. The tax rate is 30%.
- Cost of Debt: ₹1,00,000 × (1 – 0.3) / ₹10,00,000 = ₹70,000 / ₹10,00,000 = 7%
If the company pays a dividend of ₹4 per share on shares priced at ₹40, with 5% dividend growth:
- Cost of Equity: Ke = ₹4 / ₹40 + 0.05 = 0.10 + 0.05 = 15%
Here, the cost of equity (15%) is higher than the cost of debt (7%), as expected.
Importance for Students and Business
Understanding the difference between cost of debt and cost of equity helps students answer exam questions, solve MCQs, and analyze business scenarios. It also guides real-world financing decisions, such as choosing between bank loans and issuing shares.

Conclusion
To sum up, the difference between cost of debt and cost of equity is central to financial management. Cost of debt is the after-tax interest paid on borrowings, while cost of equity is the expected share return. Mastering both concepts is crucial for exams, business decisions, and understanding overall business finance.
FAQs on Difference Between Cost of Debt and Cost of Equity Explained
1. What is the difference between cost of debt and cost of equity?
The cost of debt represents the interest a company pays on borrowed funds, while the cost of equity reflects the return shareholders expect on their investment. Key differences include tax deductibility of debt interest, the risk profile for each, and the impact on ownership structure.
2. What is the difference between debt and equity?
Debt is borrowed capital, requiring repayment with interest. Equity represents ownership, providing returns through dividends and capital appreciation. Debt is a liability; equity is ownership. Understanding this difference is critical in financial management and capital structure analysis.
3. Why is equity more expensive than debt?
Equity is typically more expensive than debt because shareholders bear greater risk. They are last in line for repayment if the business fails, while debt holders have priority. Also, interest on debt is often tax-deductible, further reducing its effective cost.
4. What is the cost of debt and cost of equity formula?
There isn't one single formula. Cost of debt is often calculated as: Interest expense × (1 – Tax rate) / Total debt. Cost of equity can be calculated using the Capital Asset Pricing Model (CAPM) or the Dividend Discount Model (Gordon Growth Model), depending on the available data and context. Accurate calculation is key for financing decisions.
5. Can cost of debt be higher than cost of equity?
While unusual, the cost of debt can exceed the cost of equity in situations involving high-risk companies or those experiencing financial distress. Generally, however, equity carries a higher cost reflecting its higher risk profile compared to debt.
6. How does capital structure affect the overall cost of capital?
A company's capital structure—the mix of debt and equity—significantly impacts its weighted average cost of capital (WACC). The optimal capital structure balances the lower cost of debt with the higher cost of equity to minimise the overall cost of funds for financing decisions.
7. What is the primary difference between cost of debt and cost of equity?
The core difference lies in the nature of the funding source. Cost of debt is the explicit cost of borrowing, while cost of equity is the implicit cost reflecting the return shareholders demand for taking on the company's risk. This distinction is vital for understanding a firm's financial management and capital structure.
8. What is the difference between cost of equity and debt?
Cost of equity represents the return investors expect on their equity investment, while cost of debt is the interest expense on borrowed funds. Equity investments entail greater risk, usually resulting in a higher cost than debt which is senior in claim during liquidation.
9. What is the relationship between cost of debt and cost of equity?
The relationship is inversely correlated with the company's leverage. As debt levels increase, the risk for equity holders rises, leading to a higher cost of equity. However, the tax deductibility of debt interest can offset this to some degree.
10. How to find the cost of debt/equity?
The cost of debt can be calculated using the formula: Interest expense × (1 – Tax rate) / Total debt. The cost of equity can be estimated using various models, such as the Capital Asset Pricing Model (CAPM) or the Dividend Discount Model (DDM), based on market data and company-specific factors. The choice of method depends on data availability and context. This is essential for any financial management student.
