Frequently Asked Questions

How is after-tax cost of debt calculated?

After-Tax Cost of Debt = Pre-Tax Cost of Debt x (1 - Tax Rate). Since interest expense is tax-deductible for most companies, the real cost of debt financing is lower than the stated interest rate.

How do I find my marginal tax rate if I don't know it directly?

Marginal Tax Rate = 1 - (Net Income / Pre-Tax Income), derived from a company's own income statement -- useful when the applicable statutory rate isn't directly known.
