For your retirement planning, you are currently depositing $350 per month into an account that earns an 8% return, compounded monthly. In 12 years, you expect to increase that deposit by $250 per month (to a total of $600 per month). You plan to retire in 40 years. After you retire, you will move the money into a safe account that earns a guaranteed 3.5% per year.
