Tiny steps to a paid off car

I just made an extra payment to my car loan. I had planned on paying $250 out of this paycheck but $180 of it comes out of my bank account automatically in a few days. Therefore, I paid the difference of $70 ... $48.50 of it went to the principal and $21.50 went to interest.

Knowing that this is my next debt to pay off, I keep crunching numbers and figuring when it will be paid off. I'm such a number nerd. I think I can pay off my car loan by November which is about 10 months before the bank's scheduled pay off date!

BUT...this could also be set back if my dentist bill is high :( I'll know soon.
