Frequently Asked Questions
How do I find my car's fuel efficiency?
Check your vehicle's owner's manual or the sticker on the driver's side door jamb. You can also look up your car's EPA fuel economy rating at fueleconomy.gov. For real-world estimates, divide your miles driven by gallons used at your last fill-up.
Does this calculator account for city vs. highway driving?
No. This calculator uses a single fuel efficiency value. For mixed driving, you can use a blended average. Typically, highway driving gets better mileage than city driving, so adjust accordingly based on your route.
How accurate is this fuel cost estimate?
The estimate is as accurate as the values you enter. Actual fuel consumption can vary based on driving conditions, speed, terrain, weather, vehicle load, tire pressure, and driving habits. Use this as a planning tool rather than an exact prediction.
Can I use this for a round trip?
Yes. Simply enter the total round-trip distance (double your one-way distance) to calculate the fuel cost for your entire journey.
