Gas Guzzling Comparison Calculator

Enter the current gaz guzzling MPG of that SUV you bought when gas was $1.49 a gallon, and then enter the new MPG of that new Prius you've been thinking about. Then enter your daily round-trip commute, your driving days per year and the number of years to add up. My default investment return is a reasonable 5%.

Have fun!
