Solved: VB 2008 Help

[Coke23]

Im new at this i know im doing something wrong. This is my project
$15000 is deposited into a savings paying 5 % interest and $1000 is withdrawn at
the end of each year. How many years will it take for the account to be depleted.

Note if at the end of a certain year the balance is $1000 or less, then the final
withdrawl will consist of that balance and the account will be depleted.

this is the code i have but something is not write can anyone help PLS
Private Sub btnYears_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnYears.Click
Dim Deposite = 15000
Dim Interest = 0.05
Dim Subtract = 1000
Dim Years = 1
Do While Deposite <= 15000
Deposite = (Deposite * Interest) + Subtract
Years += 1
Loop
txtYears.Text = " The number of years to deplete 15000 = " & Years
End Sub

You are adding "$1000" to the "account" every iteration (line 8). Try this, and then write again if there is still a problem.

Thanks Thread told u i was new at this and it would be something simple.
i was using the + Subtract as ( and subtract).
I changed what u said and i still got a warning (Arithmetic operation resulted in an overflow.)
so i changed the
Do While Deposite <= 15000 to
Do While Deposite = 15000

I get an answer of 2 years. hopefully this is it.
Thanks again Thread

Two years seems a bit short for $15,000. You also need to work out the interest, add it to the account balance then take the withdrawal. At the moment you are setting the account balance to the interest minus the withdrawal, which will give you an incorrect answer.
