Question

Suppose that you are age 25 today and plan on retiring at age 65. You determined that you need to have saved $442913 in real dollars by the time you retire. How much must you contribute (in real dollars) each year to your retirement account to achieve your goal? Assume the following: you make annual contributions; each contribution is the same amount in real dollars; the first contribution will be one year from today; your last contribution will be at age 65; your portfolio earns a real annual rate of return of 6.15%, compounded annually.

Explanation / Answer

Annuity = [PVA x r] / [1 - (1 + r)-n]

= [$442,913 x 0.0615] / [1 - 1.0615-40]

= $27,239.15 / 0.9081 = $29,994.95
