When you start your first industry position, you should make enough money to start saving for your retirement. A number of Certified Financial Planners suggest you save 10% of your pre-tax paycheck for retirement. If you assume 25% of your paycheck goes to taxes, then you would have 65% of your paycheck left to spend on your bills (student loans have to be paid back), travel (see the world), entertainment season tickets), philanthropy (donating money to to suppor research), etc. If we assume that you get an annual 2% raise but maintain splitting your paycheck 10%/25%/65% (Retirement/Taxes/Expenses), how many years will you have to work to accrue enough money to be able to retire? For this problem assume your retirement investments gain 7% compounded annually and that you can comfortably retire utilizing the 4% Rule (see below). Also, assume a starting salary of $68,000 (national average for Entry-Level Chemical Engineer). * The 4% rule states that once you have accrued 25 times your yearly expenses, you can safely live off the interest gained on your investments for the rest of your life. For Extra Credit, change your allocations to 15%/25%/60%, 25%/25%/50%,35%/25%/40%, and 45%/25%/30%. How many years will you have to work to reach retirement based on each of these
