What does the PMT function calculate?

The PMT function in Excel is specifically designed to calculate the periodic payment amount for a loan based on constant payments and a fixed interest rate over the life of the loan. This function factors in the principal amount borrowed, the interest rate, and the number of total payment periods, allowing users to determine how much they need to pay regularly (such as monthly) to fully repay the loan by the end of the term.

By using the PMT function, individuals can effectively plan their budgets and understand their repayment obligations, making it a crucial tool for anyone managing loans or mortgages. The core focus of the PMT function is on the payment itself, rather than aspects like total interest paid, remaining balance, or the initial loan amount. These other choices don't represent the primary purpose of the PMT function but rather pertain to different financial calculations related to loans.
