Question

Write a compound interest calculator. The compound interest formula is:

Where:

P = principal amount (the initial amount you borrow or deposit)

r = annual rate of interest (as a decimal)

t = number of years the amount is deposited or borrowed for.

A = amount of money accumulated after n years, including interest.

n = number of times the interest is compounded per year

Here is a link to a site that explains how compound interest is calculated:

Private Sub btnCalculate_Click(ByVal sender As

System.Object, ByVal e As System.EventArgs) Handles

btnCalculate.Click

Dim principal, years As Integer

Dim rate, interest, amount As Single

principal = txtPrincipal.Text

years = txtYears.Text

rate = txtRate.Text

amount = principal * Math.Pow((1 + rate / 100), years)

interest = amount - principal

txtInterest.Text = interest

End Sub

Private Sub btnClear_Click(ByVal sender As

System.Object, ByVal e As System.EventArgs) Handles

txtPrincipal.Text = " "

txtYears.Text = " "

txtRate.Text = " "

txtInterest.Text = " "
