Using HTML/Javascript, create a webpage for calculating the future value of an investment. You will need to get three values from the user: initial amount of money, annual interest rate, and number of years for the investment. Use number inputs (numeric up downs) to get the values from the user. Also have a button and a result page. When the user clicks the button, display the result. Here's the formula for calculating the interest:

FV = PV(1 + r) ^ 12n

where FV is the future value of the investment, PV is the present value(initial amount of money), r is the monthly interest rate, and n is the number of years. Note that you will need to convert the annual intrest rate into the monthly interest rate.
