Which function would you use to find the periodic payment needed to pay off a loan in a specific number of periods?  A. RATE  B. NPR  C. PV  D. PMT

To find the periodic payment needed to pay off a loan in a specific number of periods, you would use option D. PMT.

Explanation:

• PMT (Payment) function is specifically designed to calculate the amount of payment required to repay a loan based on the loan amount, interest rate, and the number of payment periods.
• In contrast:
  • RATE is used to determine the interest rate for an investment or loan.
  • NPR typically refers to "Net Present Value" and is not directly related to calculating periodic payments.
  • PV (Present Value) is used to find the current value of a future amount of money or stream of cash flows given a specified rate of return.

Thus, if your objective is to calculate the regular payment for a loan, the PMT function is the appropriate choice.
