For projects financed by a loan or mortgage, the total debt payment is the sum of interest and principal payments:

Total Debt Payment =
Debt Interest Payment + Debt Payment

Payments are calculated annually. The annual interest payment is the product of Rate and Loan (Debt) Fraction on the Financials page and Total Installed Costs on the Costs page. Debt Payment is the principal payment, and is a function of the Rate, Term, and Loan (Debt) Fraction on the Financials page.
