At your age (assume 20) you can assume that you will live to be 100. If you graduate at 23 and start to work, you can expect to work for 47 years, until age 70. At that time you will be eligible for full Social Security benefits, which can reasonably be expected to be $3,000 per month, and which will be received monthly for the rest of your life. You can reasonably expect that your retirement savings will earn an average of 8 percent per year throughout the period that you accumulate your retirement funding and during your retirement years. Further, assume that you will want to have an annual income of $120,000 throughout your retirement.
