Question about numeric up/down control

[lifeshortlivitup]

Hello...

I have designed a program to allow the user to input a future value dollar amount, interest rate, and number of years and click calculate in order to display how much money needs to be deposited at the 5, 10, 15, 20, 25, and 30 year marks within a text box. My program works and gives me the correct output with one exception. Every time I try it, it will give me the ouput for every year from 5 through 30 vice just every five years. How do I make it only give me an output at 5 year intervals? Here's part of my code that deals with it...any pointers would be greatly appreciated. Thanks.

' set output header
      output = "Year" & ControlChars.Tab _
         & "Amount on Deposit Needed" & ControlChars.CrLf
 
      ' calculate amount after each year and append to string
      For yearCounter = 5 To years
         presentValue = _
            futureValue / ((1 + interest / 100) ^ yearCounter)
         output &= (yearCounter & ControlChars.Tab & _
            String.Format("{0:C}", presentValue) & ControlChars.CrLf)
      Next
 
      resultTextBox.Text = output ' display result
