Case Study Information A friend is celebrating her birthday and wants to start saving for her anticipated retirement. She has the following years to retirement and retirement spending goals. Because your friend is planning ahead, the first withdrawal will not take place until one year after she retires. She wants to make equal annual deposits into her account for her retirement fund. Required: 1) If she starts making these deposits in one vear and makes her last deposit on the day she retires, what amount must she deposit annually to be able to make the desired Withdrawals at retirement? 2) Suppose your friend just inherited a large sum of money. Rather than making equal annual payments, she decided to make one lump-sum deposit today to cover her retirement needs. What amount does she have to deposit todiy? 3) Suppose your friend's employer will contribute to the account each year as part of the company's profit-sharing plan. In addition, your friend expects a distribution from a family trust several years from now. What amount must she deposit annually now to be able to make the desired withdrowals at retirement? 4) Go back and assume the basic information from part 1 above - no inheritance and no employer contributions. Now assume that the inflation rate is \\( 3.0 \\mathrm{X} \\). Conseguenclic. when your friend retires she will want to withdrow \\( \\$ 105,000 \\) each vear in todoys dollars. What amount is she planninc to recelve in year 31 (the end of her fins year of retirement)? 5) How much does she need to have in retirement at the end of year 30 in order to receive her retirement payments assuming that these retirement payments continue to increase at \\( 3.0 \\mathrm{X} \\) per vear throughout her retirement? 6) If she starts making deposit amounts in one war and makes equal depont amounts exch vear and makes her last deposit on the diy she retires, what amovat must she deposit annualy to be able to make the desired withdrawals at retirement? 7) if she starts making deposit amounts in one vear and her deposits increase at the inflation rate of \\( 3.0 \\mathrm{~K} \\) each year until she maks her iast deposit on the dar she retires, what amount must she initially deposit to be able to make the desired wichdrawals at retirement? Case Information: Years untal retirement Amount to withdraw each yean Years to withdraw in retirement interest rate: Ination rate: Employer's annual contribution: Years until trust fund distribution: Amount of trust bund distribution: 5. \\( \\begin{array}{r}30 \\\\ \\hline\\end{array} \\) 25 8.5x 3.00 \\( 5 \\quad 2,100 \\) 25 5. 29,500 In order to answer ary of these equestions, first we need to know how much your friend will need when she is ready to retire. Since this amount will be the same for each of the parts of the problem solve for this amount below: Amount needed at retirement: \\( 1,023,419 \\) 1 The amount your friend mant save each year to fund her retirement is: Amount to cave each year: 2 The lume sum your friend munt deposit today to fund her retirement is: urmp sum deposited today \\( \\$ 133,140 \\) 3 To tind the amount of the annual deposit now, at is easier to break down the components of the problem. Doing so for each of the following to tind your friend's annual deposit, we get Value of emplover's contribution at retirement: Value of trust fund at retirement: Amount to save each rear now: Annual retirement payment in 31 years equal to \\( \\$ 100,000 \\) io todar's dollars 5 Crowing amuity factor for retirement period (wo \\( r \\) s) Dividine by res Amount needed at retiremene 6 PV now of amount reeded at retirement Growine annity bacr for working period (wo in) Oivieling by \\( r_{e} \\) Ameunt to save each year 2 Amount needed to save this year and then linereasing by \\( 3.0 \\mathrm{X} \\) each vear to reach the amount needed at retirements
