I am looking for an Excel worksheet example of a loan schedule with a balloon payment at the end. My internet search has not found much on the subject.Applicants must complete the Clark. University PLUS Loan Request Form. There will be no prepayment penalty. A balloon payment is a large one-time amount due at the end of a loan. Mortgages, auto loans, and business loans have been structured for balloon payments. Set loan terms with larger payments at the end.
