An employee is considering two job offers. First offer: $60,000 yearly salary with 100% matching up to 6% of yearly salary 401(k) plan Second offer: $70,000 yearly salary with 75% matching up to 7% of yearly salary 401(k) plan The employee plans to stay at either job for at least 15 years, assumes there are no salary increases, and will make 401(k) contributions at the same rate the company matches. After 15 years, with an assumed average annual growth rate of 5%, the first job offer will have an estimated 401(k) balance of $155,365.66. Which job offer will have the higher 401(k) balance after 15 years, and by how much?
