What does after tax cost of debt mean?
Keeping this in consideration, what is after tax cost of debt?
The after-tax cost of debt is the initial cost of debt, adjusted for the effects of the incremental income tax rate. The formula is: Before-tax cost of debt x (100% - incremental tax rate) = After-tax cost of debt. For example, a business has an outstanding loan with an interest rate of 10%.

The cost of new debt is so important because primary concern with the cost of capital is its use in capital budgeting decisions. The yield to maturity on outstanding debt (which reflects current market conditions) is a better measure of the cost of debt than the coupon rate.
