Gas Guzzling Comparison Calculator

Enter the current gas guzzling km/litre of that SUV you bought when gas was $1.20 a litre, and then enter the new km/litre 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. (Note: if you are used to using "litres/100km" just devide the number of litres into 100kms to give you the number of kms per litre.) My default investment return is a reasonable 5%.

Have fun!
