Your goal is to retire in 20 years. You plan to start on this path by saving $200 a month. If you earn 6% annually (using monthly compounding), how much will you have saved in 20 years?

Right before you started saving, you were notified by your auto insurance company that you will receive a discount of $20 a month on your auto premium because of your impeccable driving record. If you chose to put those savings towards your retirement goal each month, how much would your retirement account be worth if you save $220 a month for 20 years with an annual return of 6% (compounded monthly)?

Please discuss your thoughts on the impact of saving an additional $20 a month over 20 years.
