Pretax Cost of Debt

Several factors can increase the cost of debt, depending on the level of risk to the lender. These include a longer payback period, since the longer a loan is outstanding, the greater the effects of the time value of money and opportunity costs. The riskier the borrower is, the greater the cost of debt since there is a higher chance that the debt will default and the lender will not be repaid in full or in part. Backing a loan with collateral lowers the cost of debt, while unsecured debts will have higher costs. The cost of debt is the effective rate that a company pays on its debt, such as bonds and loans. These shareholders also receive returns on their shares, meaning they get something back for investing in the company. With debt equity, a company takes out financing, which could be small business loans, merchant cash advances, invoice financing, or any other type of financing.

As a business, you can generally take a tax deduction for the interest expense of your loan. Thus, the after-tax cost of your debt is usually a better representation of the true cost of the loan. Therisk-free rate of return is the lowest rate of return that investors are willing to accept in exchange for not assuming any financial risk — usually approximated as the yield on three-month U.S. The traditional approaches to determine the cost of equity use the dividend capitalization model and the capital asset pricing model . If we have to compare cost of debt with cost of equity, then we have to calculate it after adjustment of tax because interest is deducted from profit before tax but dividend is deducted from profit after tax. BFor developed countries, either the home-country or local-country cost of debt may be used. There is no need to add a country risk premium as would be the case in estimating a local emerging country’s cost of debt.

Calculating cost of debt: an example

It’s calculated by a business’s accounting department to determine financial risk and whether an investment is justified. To calculate the after-tax cost of debt, we multiply the cost of debt by the difference of 1 minus the effective tax rate. We use the company’s state and federal rates combined to determine the effective tax rate, not the marginal tax rate, which includes many tax offsets like foreign tax rate deductions. The first approach is to look at the current yield to maturity or YTM of a company’s debt.

The cost of debt for a company is basically the amount of interest expense paid to debtholders and creditors. The effective interest rate is the weighted average interest rate, as calculated above. Long-term rates are better at approximating interest rate costs over time because they match the long-term focus of calculating free cash flows and their present-day values.

Cost of Capital: What It Is & How to Calculate It

In this equation, the required return is the same as the company’s cost of equity. To continue with our earlier example of a company with an annual dividend of $1.20 per share, a 9% cost of equity, and a 5% dividend growth cost of debt rate, the Gordon Growth Model values the stock at $30 a share. If the stock trades for more than $30, then investors aren’t being adequately compensated for the risk they’re taking by investing in the company.

Note also the adjustment made to the local borrowing cost for country risk. The risk-free rate of return is the US Treasury bond rate converted to a local nominal rate of interest.

Examples of Cost of Debt Formula (With Excel Template)

The company’s capital cost is the sum of the Cost of debt plus the Cost of equity. Debt and equity capital both provide businesses with the money they need to maintain their day-to-day operations. Equity capital tends to be more expensive for companies and does not have a favorable tax treatment. Too much debt financing, however, can lead to creditworthiness issues and increase the risk of default or bankruptcy.

The outstanding debt and preference share are available on the balance sheet. The weight of the debt component is computed by dividing the outstanding debt by the total capital invested in the business, i.e., the sum of outstanding debt, preferred stock, and common equity. At the same time, the value of common equity is calculated based on the stock’s market price and outstanding shares. Companies use this method to determine rate of return, which indicates the return that shareholders demand to provide capital. It also helps investors gauge the risk of cash flows and desirability for company shares, projects, and potential acquisitions. In addition, it establishes the discount rate for future cash flows to obtain value for a business.

Why this matters for your small business

Additionally, there is a tax benefit for debt as interest expense is deductible for calculating taxable income. The cost of debt should always be presented after factoring in tax savings.
