Hello! My question does not concern the CFA. I hope it is still okay if I post it here.

I need to calculate the cost of debt with the yield to maturity approach for Coca Cola for a university course. I can only find very basic formulas online, but never applied to a real company. Could someone explain to me in more detail how I can calculate the cost of debt for Coca Cola with YTM?

Thank you very much in advance!
