I ran across an interesting calculator over at Edmunds.com. They have come up with what they call the Gas-Guzzler Trade-In Calculator which calculates how long it will take to completely pay off a new more fuel efficient vehicle and actually start saving money. I ran the calculator on my current situation, and I can confidently say I will not be buying a hybrid any time soon:
Vehicles used in my calculation:
Trade-In Vehicle: 2000 Dodge Interpid (fully paid off).
Fuel Efficient Vehicle: 2008 Toyota Prius.
Fuel-Efficient Vehicle Sales Price: $28.176
My Trade-In Value: -$2,188
Cost of Fuel-Efficient Car Minus Trade-In: $25,988
MPG of Fuel-Efficient Vehicle: 47
MPG of My Trade-In: 22
Number of Miles Driven per Month: 800
Price of Gas: $4.30/gallon
Amount Saved On Gas (per month): $83.17
Number of months to break even and begin saving money on gas: 312 (26 years)
In my personal situation, buying a hybrid would not make much financial sense at all. So to see the impact of trading in a true “gas guzzler”, I ran the same calculation on my work vehicle:
Trade-In Vehicle: 1992 Chevy Suburban (fully paid off).
Fuel Efficient Vehicle: 2008 Toyota Prius.
Fuel-Efficient Vehicle Sales Price: $28.176
My Trade-In Value: -$329
Cost of Fuel-Efficient Car Minus Trade-In: $27,847
MPG of Fuel-Efficient Vehicle: 47
MPG of My Trade-In: 13
Number of Miles Driven per Month: 800
Price of Gas: $4.30/gallon
Amount Saved On Gas (per month): $191.42
Number of months to break even and begin saving money on gas: 145 (12 years)
So in the long run, yes you can save money on buying a hybrid. But in the short run, you are better off sticking to your clunker, gas hog, fuel mule, etc. It will be interesting to see what kind of gas mileage they squeeze out of cars in the future. When vehicles hit a 60-80 mpg average, I’ll re-visit this calculator.
