MPG Calculator

To determine total fuel consumed and the financial cost of any journey, the calculator utilizes a set of straightforward relationships between distance, efficiency (in miles per gallon or liters per 100 km), and fuel price. The core formulas used are:

Fuel Burned = Distance × (Efficiency / 100) (adjusted for standard scaling factors)

Total Cost = Fuel Burned × Price per Unit

By inputting any combination of known variables, you can effortlessly solve for the missing metrics like total journey expenditure or expected fuel usage.

Imagine you are planning a weekend excursion and want to estimate your expenses. You plan to drive a Distance of 300 miles. Your vehicle has an average fuel economy Efficiency rating of 25 miles per gallon, and the current local fuel Price is $3.50 per gallon.

First, calculate the fuel burned: 300 miles divided by 25 mpg yields 12 gallons of fuel consumed. Next, multiply those 12 gallons by the price of $3.50 per gallon. The total estimated Cost for your trip fuel will be $42.00.

Maximize your vehicle's mileage and lower your overall driving expenses by keeping these best practices in mind:

Maintain Proper Tire Pressure: Under-inflated tires create extra rolling resistance, forcing your engine to work harder and burning significantly more gas.

Reduce Excess Weight: Clearing heavy, unnecessary items out of your trunk lightens the load, directly improving your miles per gallon over long distances.

Drive at Moderate Speeds: High-speed highway driving increases aerodynamic drag. Maintaining a steady, moderate pace preserves fuel efficiency.
