Keeping up with the Joneses is an expensive proposition. From that new boat to replacing the pool filter to booking vacation to Hawaii, there are quite a few expenses involved. It might be hard to keep track of all the junk in your yard, but how do you track those pesky expenses? Thank goodness for Mint.

Mint is an online personal finance tracker that can keep tabs on bank accounts, credit cards, and investments. The cool thing about it is it automatically categorizes your spending, making it easier to analyze. It will tell you how much you burned at P.F. Chang’s last week, exactly how much you are paying in interest on your VISA, and will even let you make custom budgets. Best of all, it’s free! It can even travel with you on the iPhone or iPod Touch.
