|IRR||Returns a Double specifying the internal rate of return for a series of periodic cash flows (payments and receipts).|
|MIRR||Returns a Double specifying the modified internal rate of return for a series of periodic cash flows (payments and receipts).|
|NPer||Returns a Double specifying the number of periods for an annuity based on periodic fixed payments and a fixed interest rate.|
|NPV||Returns a Double specifying the net present value of an investment based on a series of periodic cash flows (payments and receipts) and a discount rate.|

This example uses the Rate function to calculate the interest rate of a loan, given the total number of payments (TotPmts), the amount of the loan payment (Payment), the present value or principal of the loan (PVal), the future value of the loan (FVal), a number that indicates whether the payment is due at the beginning or end of the payment period (PayType), and an approximation of the expected interest rate (Guess).
Sub TestRate() Dim PVal, Payment, TotPmts, APR As Double Dim PayType As DueDate ' Define percentage format. Dim Fmt As String = "##0.00" Dim Response As MsgBoxResult ' Usually 0 for a loan. Dim FVal As Double = 0 ' Guess of 10 percent. Dim Guess As Double = 0.1 PVal = CDbl(InputBox("How much did you borrow?")) Payment = CDbl(InputBox("What's your monthly payment?")) TotPmts = CDbl(InputBox("How many monthly payments do you have to make?")) Response = MsgBox("Do you make payments at the end of the month?", MsgBoxStyle.YesNo) If Response = MsgBoxResult.No Then PayType = DueDate.BegOfPeriod Else PayType = DueDate.EndOfPeriod End If APR = (Rate(TotPmts, -Payment, PVal, FVal, PayType, Guess) * 12) * 100 MsgBox("Your interest rate is " & Format(CInt(APR), Fmt) & " percent.")
