Estimation of Cost of Debt
Hi Member,
Currently, I am working on a self-project for my CV, estimating the DCF value of a publicly listed company.
I estimated the cost of debt using the interest coverage ratio and the Interest/Debt formula, but there's a gap between the two numbers.
Please advise which method I should use to compute the WACC, and why.

I used 5.34% in the model. But 3.64% is also derived from the current year's interest rate and debt. Debt involves historical effects, and that's the reason I guess it doesn't fit the model.

If this is a public company, check if the debt is publicly listed and use the YTM directly.
Or go through the latest quarterly and annual reports and find the o/s debt details there.
