About Gas Mileage Savings Calculator: Car Cost vs. Fuel Savings

You would like to save money on gas so you're considering trading in your gas guzzler for a more fuel efficient car. This calculator shows how long will it take before you pay off the balance of a vehicle purchase and really begin saving money.

Based on the EPA's MPG data and assuming 45% highway driving and 55% city driving. MPG data for model years 2007 and prior have been adjusted downward to reflect the EPA's new testing methodology adopted for 2008 model year vehicles.

If you have selected a vehicle and entered your ZIP Code, we pre-populate each variable field in the Financial Calculators with our estimates. These amounts are based on True Market Value® prices and standard industry data, but the values that apply to your purchase or lease are likely to vary. When available, you should use the information provided to you by your dealer or lender.
