Cost of Debt vs. Interest Rate: What's the Difference?
Cost of debt is the effective rate a company pays on its borrowed funds, accounting for tax benefits, while interest rate is the percentage charged on the principal by a lender.
Cost of debt is a comprehensive measure, reflecting the total expense of borrowing including interest and other fees, adjusted for tax implications. Interest rate, in contrast, is simply the percentage charged on the principal amount of a loan or debt.
The cost of debt guides businesses in financing decisions, indicating the true burden of borrowing after tax deductions. Interest rate primarily affects the periodic payments on loans, influencing borrower’s immediate cash outflows.
Cost of debt includes the effect of tax shields, as interest expenses are often tax-deductible, reducing the overall cost. Interest rate itself does not account for tax implications; it is a gross figure before any tax benefits.
In investment analysis, cost of debt is crucial for calculating the weighted average cost of capital (WACC), affecting valuation and investment decisions. Interest rate directly influences the cost of borrowing but is just one component of the broader cost of debt.
Cost of debt can vary based on a company’s creditworthiness and market conditions, providing insight into the risk profile of the company. Interest rate is set by lenders based on factors like credit risk, market rates, and loan terms, and can fluctuate with market conditions.
