Which of the following is not a required input for the PMT function?

• A. Interest Only Period
• B. Rate
• C. Nper
• D. Pv

Answer: (A)

PMT calculates a fixed loan payment from three essential pieces: the interest rate per period, the total number of payments, and the loan amount (present value). These three are the required inputs for the function. The function signature includes optional arguments for the future value and the timing of payments, but you don’t pass anything like an “Interest Only Period” as a separate input. If a loan has an interest-only phase, you model it by splitting the schedule or using separate calculations for that phase, not by a dedicated PMT parameter. That’s why the option referring to an interest-only period isn’t a required input.
