Pmt function
Summary
Returns the payment amount for an annuity, based on constant payments and a constant interest rate.
Syntax
Pmt(rate, nper, pv, [ fv, [ type ]])
The Pmt function has these named arguments:
Part
Description
rateRequired. Double specifying interest rate per period. For example, if you get a car loan at an annual percentage rate (APR) of 10 percent and make monthly payments, the rate per period is 0.1/12, or 0.0083.
nperRequired. Integer specifying total number of payment periods in the annuity. For example, if you make monthly payments on a four-year car loan, your loan has a total of 4 * 12 (or 48) payment periods.
pvRequired. Double specifying present value (or lump sum) that a series of payments to be paid in the future is worth now. For example, when you borrow money to buy a car, the loan amount is the present value to the lender of the monthly car payments you'll make.
fvOptional. Variant specifying future value or cash balance you want after you've made the final payment. For example, the future value of a loan is $0 because that's its value after the final payment. However, if

Example
This example uses the Pmt function to return the monthly payment for a loan over a fixed period. Given are the interest percentage rate per period (APR / 12), the total number of payments (TotPmts), the present value or principal of the loan (PVal), the future value of the loan (FVal), and a number that indicates whether the payment is due at the beginning or end of the payment period (PayType).
Dim Fmt, FVal, PVal, APR, TotPmts, PayType, Payment
Const ENDPERIOD = 0, BEGINPERIOD = 1 ' When payments are made.
Fmt = "###,###,##0.00" ' Define money format.
FVal = 0 ' Usually 0 for a loan.
PVal = InputBox("How much do you want to borrow?")
APR = InputBox("What is the annual percentage rate of your loan?")
If APR > 1 Then APR = APR / 100 ' Ensure proper form.
TotPmts = InputBox("How many monthly payments will you make?")
PayType = MsgBox("Do you make payments at the end of month?", vbYesNo)
If PayType = vbNo Then PayType = BEGINPERIOD Else PayType = ENDPERIOD
Payment = Pmt(APR / 12, TotPmts, -PVal, FVal, PayType)
MsgBox "Your payment will be " & Format(Payment, Fmt) & " per month."
