How to estimate fuel spending

Turn your driving distance, measured fuel economy, and local pump price into a weekly, monthly, and annual planning estimate.

  1. 01

    Choose the distance period

    Tell the calculator whether your entered mileage is per week, month, or year.

  2. 02

    Enter your current scenario

    Use miles, US mpg, and USD per US gallon. A measured average is more useful than an advertised figure.

  3. 03

    Add an alternative

    Enter a second mpg figure to compare another car or driving scenario at the same distance and fuel price.

READING THE RESULT

Gallons equal miles divided by US mpg; cost equals gallons multiplied by price. Monthly cost is an annual average based on 12 months, while weekly planning uses 52 weeks.

WHAT IT DOES NOT DO

The estimate covers fuel only. It excludes maintenance, insurance, financing, depreciation, and changes in fuel price or driving conditions.

Your driving, your inputs

Example values only. Replace the pump price and consumption with your own.

Compare a second scenario

Both scenarios use the same distance and fuel price. This is an input comparison, not a predicted gain from a modification.

A clearer running cost.

15,600 miles / year · 624 US gallons in the current scenario

Current cost per mile: $0.16. Fuel only; excludes maintenance, insurance, and other ownership costs.

Make the assumptions visible.

Gallons = miles ÷ US mpg. Cost = gallons × the entered price. A planning year uses 52 weeks or 12 months. Monthly output is an annual average, not a four-week estimate. Changing the distance period changes the interpretation of the entered miles.

Prices and real-world consumption vary. Use measured consumption where possible and review the estimate when your driving changes. FuelEconomy.gov provides additional fuel-cost context.
