Unit 33: PMT
The PMT Function (short for payment) calculates periodic payments for a loan. It is a financial function that is commonly used to determine the periodic payment for a new car loan, for example.
When you are using the PMT Function, you need to know a variety of details about the loan:
-
Price of Item (car, boat, yacht, etc.)
-
Down Payment (in dollar amount – could be around 10%-15%, but a variety of down payment amounts are sometimes available)
-
Loan Amount (Price of Item – Down Payment)
-
Period Length (how often payments are made each year – the period might be daily, weekly, monthly, quarterly, or semi-annually)
-
Periods Per Year (how many payments are made each year)
-
Interest Rate (expressed in rate per year, also known as APR – annual percentage rate – this is the rate of interest the lender will charge and how the lender makes a profit)
-
Rate Per Period (APR / Periods Per Year)
-
Term (Years in the Loan)
-
Total Periods in Life of Loan (Periods Per Year X Term, Nper argument)
Pay close attention to the cell reference you put in the Rate field – this is the interest rate per period, not the APR or annual percentage rate.
