Fuel Savings Comparison
Estimate savings from a more efficient vehicle.
Calculate fuel savings comparison from clear inputs
Fuel Savings Comparison gives a focused worksheet for home & diy questions where a quick deterministic estimate is more useful than a spreadsheet. The fuel savings comparison fields mirror the variables in its formula, and the output separates the main result from supporting values so you can sanity-check this calculation before reusing it.
12000 miles at 3.75 per gallon costs 1875 at 24 MPG and 1406.25 at 32 MPG.

Frequently Asked Questions
How are the fuel costs calculated?
Miles ÷ MPG gives gallons, times the fuel price. 12,000 miles at $3.75 a gallon costs $1,875 at 24 MPG and $1,406.25 at 32 MPG, saving $468.75 a year.
Why do MPG improvements save less at the high end?
Fuel use depends on gallons per mile, not miles per gallon. Going from 15 to 20 MPG saves far more fuel than going from 40 to 45 MPG over the same distance.
Can I use it for an electric vehicle?
Not directly. EVs are rated in kWh per 100 miles; you would need to convert electricity cost to a per-mile figure and compare that with the gas car's cost per mile.
