How does the MPG and fuel cost calculator work?
The MPG & Fuel Cost Calculator divides miles driven by fuel economy to estimate gallons used, then multiplies gallons by fuel price to estimate total fuel cost and cost per mile.
Can I compare two vehicles with this calculator?
Yes. Use the comparison fields to estimate how much fuel cost changes between vehicles with different MPG ratings over the same driving distance.
Why does real-world MPG differ from the estimate?
Actual MPG can change with traffic, speed, terrain, tire pressure, maintenance condition, weather, cargo, fuel type, and driving habits.
Is this useful for road trips?
Yes. Enter the trip distance, expected MPG, and fuel price to estimate gallons needed and fuel cost before you leave.
