Justin here. For all its quirks, it’s hard to find a better (and cheaper) place to easily track what you spend that at www.mint.com. On top of that, the Mint blog does an equally great job at relaying financial concepts in easy to understand methods; today’s post doesn’t disappoint.
Note that the y-axis numbers are misaligned with the chart for some reason, but the meat of the chart is still right (for those of you who don’t remember, the “y” axis is the vertical axis, also known as the “yo-yo” axis because it goes up and down . . . how about that?)
