Really struggling with this... Can somebody go through all the questions 1-7 and let me know how to do each? I have some done already but I'm not very confident in my answers.

Here are two additional assumptions coupled with your Part 1 assumptions to aid your planning. RIP. Assume you will pass away at age 88. Your desired annual retirement income is 75% or your final year's working salary and your annual retirement withdrawals are at the beginning of each year/ Answer the following questions to help with your retirement planning. 1. 2. 3. 4. 5. 6. What is your expected final year working salary? What is your desired annual retirement income? How much will you need at retirement to fund your desired retirement annuity (remember to use your post-retirement investment rate of return estimate)? How much will you have to deposit annually in the form of an equal annual end of the year deposit over your working career to fund your desired retirement annuity (use pre-retirement rate of return estimate)? Re-work questions 3 and 4 assuming you would like to leave your grandkids $200,000 when you die at age 88. Now, forget the grandkids and imagine you get $25,000 in graduation gifts from your family that you deposit into your retirement savings account at the beginning of your work career. We work the previous question (#4) with this new initial deposit. How large does your annual deposit over your working career need to be in addition to the initial $25,000? Looking at your answers in the last two questions, the annual amount, while doable, might be a bit of a financial stretch for you early in your career. Let's redo the scenario in the last question where you have the $25,000 initial deposit but will deposit $5000 at the end of year for the first 10 years and then another equal annual amount at the end of each year for the remaining working years. How large does this second annual deposit need to be to meet your retirement savings goal from question #3? 7. Assumptions: Age: 22 Estimated Annual Salary: $71,284 Desired Retirement Age: 60 Years Working: 38 Annual Salary Growth Rate: 4% Pre-Retirement Rate of Return: 10% Post-Retirement Rate of Return: 4% Age of Death: 88 Years After Retirement: 28 Calculations: 1) Expected Final Year Salary: $316,416.38 2) Desired Annual Retirement Income: $237,312.28 3) Ammount Needed at Retirement: $79,138.30 4) Amount Deposited Annually: $7,976.09 5) 6)
