Modelling interest expense

Hey guys,

is there any way to model interest expense and working capital without building a balance sheet projection? I want to value a company without having to build a 3 statement model. If some of you know popular practices, I’d like to know them.

Thanks!

You could just model an amortization table and use that for your debt service calculations.

working capital is just a guess anyways there is no good way to predict it with certainty
