When businesses evaluate their financing options, understanding the true cost of borrowing is crucial. The after-tax cost of debt is a financial metric that helps companies analyze the real cost of their debt, taking into account the tax deductions available on interest payments. This article delves into what the after-tax cost of debt is, why it's important, and how to calculate it, providing essential insights for financial strategists and business owners alike.
What is the After-Tax Cost of Debt?
The after-tax cost of debt refers to the net expense on borrowed funds, after accounting for tax deductions on interest expenses. Essentially, it measures the actual burden of debt on a company’s finances more accurately than the nominal interest rate.

How to Calculate the After-Tax Cost of Debt
The calculation of the after-tax cost of debt is relatively straightforward. It involves the following formula:
Where:
- Interest Rate is the nominal interest rate of the debt.
- Tax Rate is the corporate tax rate applicable to the company.
To illustrate, suppose a company has a debt with a nominal interest rate of 7% and is subject to a corporate tax rate of 30%. The after-tax cost of debt would be calculated as follows:
This means the real cost of the debt, after accounting for tax savings, is 4.9%.
Real-World Application
Consider a real-world example where a business is contemplating a $1 million loan with an interest rate of 6%. If the corporate tax rate is 25%, the after-tax cost of debt calculation would be:
This calculation shows that the actual cost of borrowing $1 million is effectively reduced by the tax shield on the interest paid.

It not only helps in assessing the cost-effectiveness of different financing options but also aids in strategic financial planning and tax management.
