Need assistance with this forum question:

Assume you start working at 20 years old and plan to retire at age 50. You contribute $125 per month to your retirement plan and the company matches it.  If you could earn 12.6% annual return over the 30 years, how much money would you have when you retire?

Suppose you worked until you were 60, then how much would you have when you retire (make sure you adjust the formula for monthly compounding)? Calculate and comment on your findings.  Include the FV of an annuity formula in your discussion.
