[RESOLVED] For loop example

[rainiam]

Hi, all

I need a "For loop" source code to do like capital and interest calculation.

for example:

I put $100 in a bank, 7% interest rate, for 2 years, compounded annually.


Thank you so much

Is this homework? Anyway heres a start

Dim Amount As Double = 100 '100$
        Dim Interest As Single = 7 '7%
        Dim Years As Integer = 2 'left in for 2 yrs
        Dim OnePercent As Double
        Dim InterestAdded As Double
 
        For i As Integer = 1 To Years
            'loop through each yr
            OnePercent = Amount / 100 'divide balance by 100 to give 1%
            InterestAdded = OnePercent * Interest 'calculate interest earnings 
            Amount += InterestAdded 'add interest to amount
        Next
 
        MessageBox.Show("After " & Years & " years at an interest rate of: " & Interest.ToString & "% your balance would be: " & Amount.ToString("c"))

the182guy, thank you so much

one more question, can I write such thing in vb:
amount = (1 + interest) ^ year

Thank you
