Fuel Cost Calculator
The fuel cost of a trip is the distance divided by your fuel economy, multiplied by the price of fuel. This Fuel Cost Calculator estimates that cost from your distance, fuel efficiency and fuel price, working in both metric and imperial units.
Tips, information for using the Average Consumption and Miles Cost Calculator
1. How to calculate fuel efficiency (average consumption)?
The formula is relatively simple, divide the amount of gasoline consumed on a given road by the distance traveled and then multiply the result by 100. So if, for example, on a 430 miles road, the car consumed 5 gallons of gasoline, then the average fuel consumption (5/430) * 100 = 1.16 gal / 100 miles.
2. How do I calculate the cost per 1 mile of gasoline?
Once you have the fuel efficiency / average consumption, it is really very easy. Average consumption is the value of how many liters of gasoline a car travels per 100 km, so if you divide it by 100, you get how much the car consumes per miles. Just multiply that number by the price of 1 gallon of gasoline and you’ll get the result. Suppose the price of gas is 2.9 USD then the cost per miles is 0.03 USD / 1 mile.
Frequently asked questions
How do I calculate the fuel cost of a trip?
Divide the trip distance by your fuel economy to get the fuel used, then multiply by the price per litre or gallon. 500 km at 8 L/100km and 1.50 per litre costs 40 × 1.50 = 60.
How do I work out fuel economy?
Divide the fuel used by the distance travelled. Filling up after 400 km on 32 litres gives 8 litres per 100 km, or about 35 miles per gallon.
How can I reduce my fuel costs?
Drive smoothly, keep tyres correctly inflated, remove excess weight and avoid high speeds, which all cut fuel use and cost.
Does the calculator support miles and gallons?
Yes. You can enter distance in kilometres or miles and fuel economy in L/100km, km/L or miles per gallon.
Why is my real fuel cost different?
Real-world economy varies with traffic, terrain, weather and driving style, so the calculator gives a close estimate rather than an exact figure.
