4. Prof. Business feels like the required 403c monthly deposit is too much of a financial stretch for her and wants you to re-figure her potential monthly retirement income using the same investment rate assumptions as #3 (6% nominal annual rate, 0.5% monthly rate before and after retirement), but with the following deposit assumptions. One, she thinks she can deposit an extra $250/month into the 403c plan for a monthly deposit of $1250 into the 403c plan for the next 8 years which makes for a total monthly deposit of $2550 the upcoming year. Also, she thinks her salary and her mandated monthly pension plan deposit will increase 2% annually and believes she can also increase her 403C plan monthly deposit 2% each year from the current monthly deposit of $2550 this upcoming year (deposits 1-12). For example, her mandated monthly pension plan deposit for year 2 (deposits 13-24) will be $2601 and will increase 2% each year until retirement. Also remember these monthly deposits are on top of the $700,000 Prof. Business has invested today. Answer the following. a. How much will Prof. Business have at retirement in 8 years under these assumptions? b. What will Prof. Business' monthly retirement withdrawal be for 20 years once she retires? 4.
