# Engineering Economic Analysis

December 22, 2015

John Doe, 23 years young newly graduated engineer just got a job in major Aerospace Co. Human resources told him that he could join the

company’s 401K Plan, and his contribution can’t exceed \$14’500 per year. But if he maximizes his contribution and invests 15 % of his

gross annual salary, then company will match every dollar of with \$0.50. He is paid \$30 per hour and he gets a 3% raise every other year,

after 20 years of work he is laid off. Roth IRA is \$5000 per year during this period. (Age23-42)
He finds another job with an annual salary of \$120’000 per year and works till his retirement (43-67). The new company doesn’t have a

retirement plan and he can only save in his Personal IRA \$15’000 per year on the average. During second half of his career the salary

increase is only 5% every three years and there are no medical benefits either.
John was assuming that at retirement he has paid off his mortgage and he doesn’t have major consumer debt and based on today’s buying

power he only needs \$3’000 to live well.
