Consider two hypothetical savers, Bert and Ernie. Bert puts $3,750 per year into a retirement account with an estimated 11.25% rate of return starting at age 25. Bert will stop making deposits after his 44^th birthday (i.e., he will make 20 total deposits), and his account will continue to grow until he retires at age 60. Ernie plans on waiting until age 30 to begin investing in a retirement account with the same 11.25% rate of return. Ernie will put $5,250 per year into the retirement account until he also retires at age 60 (i.e., he will make 30 total deposits). Neither Bert nor Ernie will make a deposit on their 60^th birthday. Who will have more in retirement and by how much? Assume that both Bert and Ernie make deposits on their birthdays, which represents the start of the year.
