You know you are getting ripped off when you walk into Starbucks and plunk down anwhere between $1.50 and $5.00 for your favorite caffeinated beverage. But how much?

This calculator will compute the total lifetime value of the money you spend on your weekly coffee habit. The value is the amount of money you would have at age 65 if you were to stick the money you spend on coffee into a basic investment account and let it accrue. Remember this, if you carry a credit card balance, the number may significantly underestimate the lifetime cost, because you are financing the purchase and paying interest over time on the balance. Not a pretty picture!
