Monica, 22 just started working full time and plans to deposit $3,000 annually into a Roth IRA earning 12 percent interest compounded annually. How much would she have after 20 years, 30 years, and 40 years? If she decided to make monthly payments of $250 per month instead of the $3,000 each year would she end up with more or less money at the end of 40 years? If she had a 30% tax rate when she took the money out 40 years from now how much in taxes would she have to pay?
