MIRR Function Example
This example returns the modified internal rate of return for a series of cash flows contained in the array Values(). LoanAPR represents the financing interest, and InvAPR represents the interest rate received on reinvestment.
Static Values(5) As Double ' Set up array.
LoanAPR = .1 ' Loan rate.
InvAPR = .12 ' Reinvestment rate.
Fmt = "#0.00" ' Define money format.
Values(0) = -70000 ' Business start-up costs.
' Positive cash flows reflecting income for four successive years.
Values(1) = 22000 : Values(2) = 25000
Values(3) = 28000 : Values(4) = 31000
RetRate = MIRR(Values(), LoanAPR, InvAPR) ' Calculate internal rate.
Msg = "The modified internal rate of return for these five cash flows is"
Msg = Msg & Format(Abs(RetRate) * 100, Fmt) & "%."
MsgBox Msg ' Display internal return
