1. What is the Cost of Debt?

The Cost of Debt represents the effective interest rate a company pays on its borrowed funds. It is calculated as the total interest expense divided by the total debt outstanding, providing a pre-tax measure of the cost of borrowing.

2. How Does the Calculator Work?

The calculator uses the Cost of Debt formula:

Where:

• Interest Expense — Total interest paid on debt during a period ($)
• Total Debt — Total outstanding debt amount ($)

Explanation: This formula calculates the pre-tax cost of debt as a decimal value, which can be converted to a percentage by multiplying by 100.

3. Importance of Cost of Debt Calculation

Details: Calculating the cost of debt is essential for financial analysis, capital budgeting decisions, and determining a company's weighted average cost of capital (WACC). It helps assess the efficiency of a company's debt financing and compare borrowing costs across different financing options.

4. Using the Calculator

Tips: Enter the total interest expense in dollars and the total debt amount in dollars. Both values must be positive numbers, with total debt greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Is this the pre-tax or after-tax cost of debt?
A: This calculation provides the pre-tax cost of debt. For after-tax cost, multiply the result by (1 - tax rate).

Q2: What time period should be used for interest expense?
A: Typically, annual interest expense is used, but the calculation can be adapted for any consistent time period as long as both interest expense and debt amounts correspond to the same period.

Q3: Does this include all types of debt?
A: Yes, this calculation should include interest expense from all outstanding debt obligations, including bonds, loans, and other borrowings.

Q4: How does this differ from the interest rate on debt?
A: The cost of debt reflects the actual interest paid relative to total debt, which may differ from nominal interest rates due to fees, discounts, or premiums on debt issuance.

Q5: When is this calculation most useful?
A: This calculation is particularly useful for financial analysis, investment decisions, and when calculating a company's weighted average cost of capital (WACC).
