Final answer:
Jane and Joe have $169,733.73 and $621,798.53 respectively in their retirement accounts at age 65. If they had contributed from the start of their working careers, Jane would have $492,618.07 and Joe would still have $621,798.53.
Step-by-step explanation:
To calculate the amount of money Jane and Joe have at age 65, we need to calculate the future value of their contributions to their 401(k) accounts.
For Jane, she contributes $2,000 annually for 9 years, starting at age 22. Joe contributes $2,000 annually for 35 years, starting at age 31. Both accounts earn a 9% annual rate of return.
- Jane's contributions: $2,000 x 9 = $18,000
- Future value of Jane's contributions at age 65: $18,000 x (1 + 0.09)33 = $169,733.73
- Joe's contributions: $2,000 x 35 = $70,000
- Future value of Joe's contributions at age 65: $70,000 x (1 + 0.09)34 = $621,798.53
If Jane and Joe had contributed from the start of their working careers, Jane would have made payments for 43 years (age 22 to 65) and Joe would have made payments for 35 years (age 22 to 65).
Using the same calculations, the future value of Jane's contributions would be $492,618.07 and the future value of Joe's contributions would be $621,798.53.
