How do I calculate my car's MPG?

Enter the distance traveled and the fuel used (in gallons) into the calculator. It will automatically compute your miles per gallon (MPG) by dividing distance by fuel used.

Can I use liters and kilometers?

Yes, the calculator supports metric units. Enter distance in kilometers and fuel used in liters to get fuel economy in L/100km, along with trip fuel cost and cost per kilometer.

What is cost per mile?

Cost per mile is the total fuel cost for your trip divided by the distance traveled. It helps you understand the fuel expense for each mile driven.

Use Cases

Track Your Vehicle's Fuel Efficiency

Monitor your car's MPG or L/100km over time to identify changes in fuel economy, which can indicate maintenance issues or driving habit impacts.

Example: After a road trip, enter 300 miles and 10 gallons to see your MPG.

Budget for a Trip

Estimate the total fuel cost for an upcoming journey by entering the expected distance, your vehicle's typical fuel consumption, and current fuel price.

Example: Plan a 500-mile trip with a car that gets 25 MPG and gas at $3.50/gallon.

Tips & Common Mistakes

Tips

For accurate MPG, fill your tank completely, reset your trip odometer, and record the distance and fuel needed to refill next time.
Use the same units (imperial or metric) for both distance and fuel to avoid calculation errors.
Check your tire pressure regularly; under-inflated tires can lower fuel economy.
Compare your calculated MPG with the EPA rating for your vehicle to spot potential issues.

Common Mistakes to Avoid

Mixing units, such as entering miles with liters, which leads to incorrect results.
Using the fuel price per gallon when you entered fuel in liters, or vice versa.
Forgetting to include the fuel used for the entire trip, not just a portion.
