Cost of Debt Formula How to Calculate it with Examples?

While the cost of equity is an expensive form of capital, companies with too much debt have a higher risk of defaulting on their debts. Because of this, investors like to see a healthy mix of financing through both debt and equity. WACC, or weighted average cost of capital, is one way to measure that mix. While the cost of debt is the rate of return that lenders expect from borrowers, the cost of equity is the rate of return that shareholders expect from companies they hold partial ownership in. The cost of equity is typically higher than the cost of borrowed money because equity financing does not have any tax advantages.

Interest paid by the firm on its current debt can be used as an estimate of the current cost of debt if nothing has changed since the firm last borrowed. However, when conditions have changed, the analyst must estimate the cost of debt reflecting current market interest rates and default risk. The after-tax cost of debt generally refers to the difference between the before-tax cost of debt and the after-tax cost of debt, which is dependent on the fact that interest expenses are deductible. It is an integral part of WACC, i.e., average weight cost of capital. The company’s capital cost is the sum of the debt cost plus the equity cost. The cost of debt is the minimum rate of return that the debt holder will accept for the risk taken.

As a preface for our modeling exercise, we’ll be calculating the cost of debt in Excel using two distinct approaches, but with identical model assumptions. To get our total interest, we’ll multiply each loan by its annual interest rate, then add up the results. Although you can use Excel or Google Sheets for bookkeeping, it’s helpful to know how to be your own cost of debt calculator. Suppose you run a small business and you have two debt vehicles under the enterprise. The first is a loan worth $250,000 through a major financial institution. The first loan has an interest rate of 5% and the second one has a rate of 4.5%.

The difference between the expected rate of return and the promised rate can be substantial. A practical alternative is to use the YTM for a number of similarly rated bonds of other firms. Such bonds include a so-called default premium, which reflects the compensation that lenders require over the risk-free rate to buy noninvestment grade debt. This methodology assumes that the risk characteristics of the proxy firms approximate those of the firm being analyzed. Table 18.2 summarizes methods commonly used for valuing cross-border M&As for developed-country and emerging-country firms. The WACC calculation assumes that the firm uses only common equity and debt financing.

How the Cost of Debt Works

Because your tax rate is 40%, that means you end up paying $40 less in taxes. Suppose a company named AIM Marketing has taken a loan for business expansion of $500,000 at the rate of interest of 8%. The tax rate applicable was 30%; here, we have to calculate the after-tax cost of debt. In this guide, you will learn about the cost of debt, as well as how to calculate it before and after taxes have been paid. You will also learn how to use Microsoft Excel or Google Sheets to calculate the cost of debt and how a tool like Layer can help you synchronize your data and automate calculations.

Loan providers want to ensure that borrowers are able to pay them back. To lower your interest rates, and ultimately your cost of debt, work on improving your credit score. Calculating the total cost of debt is a key variable for investors who are evaluating a company’s financial health. The interest rate a company pays on its debt will determine the long-term cost of any business loan, bond, mortgage, or other debts a company uses to grow. Interest is the cost of borrowing and is tax deductible by the firm; in bankruptcy, bondholders are paid before shareholders as the firm’s assets are liquidated. Default risk is the likelihood the firm will fail to repay interest and principal when required.

You can calculate the after-tax cost of debt by subtracting your income tax savings from the interest you paid to get a more accurate idea of total cost of debt. We discuss how to calculate complex cost of debt below, which includes the impact of taxes. The effective interest rate is the weighted average interest rate we just calculated. For example, if a company’s only debt is a bond that it issued with a 5% rate, then its pretax cost of debt is 5%. If its effective tax rate is 30%, then the difference between 100% and 30% is 70%, and 70% of the 5% is 3.5%.

Follow the steps below to calculate the cost of debt using Microsoft Excel or Google Sheets. Cost of debt refers to the total interest expense a borrower will pay over the lifetime of the loan. Therefore, the final step is to tax-affect the YTM, which comes out to an estimated 4.2% cost of debt once again, as shown by our completed model output.

Even though you’re paying your friend $100 in interest, because of the $40 in savings, really you’re only paying an additional $60. The after-tax cost of debt is lower than the pre-tax cost of debt. For example, let’s say your friend offers you a $1,000 loan at 10% interest, and your company’s tax rate is 40%. The effective pre-tax interest rate your business is paying to service all its debts is 5.3%. Optimize Business Growth
Increasing business income allows one to avail more debt as they can afford it, thereby reducing the cost of debt by comparing it with the income generated by the loan amount.

Simply put, a company with no current market data will have to look at its current or implied credit rating and comparable debts to estimate its cost of debt. When comparing, the capital structure of the company should be in line with its peers. Some interest expenses are tax deductible, meaning you will receive a tax break for some of your interest paid and won’t actually have to pay for all the interest charged.

Calculating the Cost of Debt

Each year, the lender will receive $30 in total interest expense twice. On the Bloomberg terminal, the quoted yield refers to a variation of yield-to-maturity (YTM) called the “bond equivalent yield” (or BEY). To find your total interest, multiply each loan by its interest rate, then add those numbers together. Adam Hayes, Ph.D., CFA, is a financial writer with 15+ years Wall Street experience as a derivatives trader.

It reflects the current level of interest rates and the level of default risk as perceived by investors. In bankruptcy, bondholders are paid before shareholders as the firm’s assets are liquidated. Default rates vary from an average of 0.52 percent of AAA-rated firms for the 15-year period ending in 2001 to 54.38 percent for those rated CCC by Standard and Poor’s Corporation (Burrus and McNamee, 2002). The cost of debt is the interest rate a borrower must pay on borrowed money, such as bonds or loans. A company’s total cost of debt is calculated by adding total interest expense and dividing it by total debt. The cost of debt is a critical measure because it directly impacts a company’s profitability and cash flow.

The degree of the cost of debt depends entirely on the borrower’s creditworthiness, so higher costs mean the borrower is considered risky. For nonrated firms, the analyst may estimate the current pretax cost of debt for a specific firm by comparing debt-to-equity ratios, interest coverage ratios, and operating margins with those of similar rated firms. The analyst would then use the interest rates paid by these comparably rated firms as the pretax cost of debt for the firm being analyzed. Much of this information can be found in local libraries in such publications as Moody’s Company Data; Standard & Poor’s Descriptions, the Outlook, and Bond Guide; and Value Line’s Investment Survey. In the United States, the FINRA TRACE database also is an excellent source of interest rate information.
