Mileage and Fuel Cost Calculator: Estimate Trip Fuel Expenses
Estimate vehicle mileage, fuel required, and trip cost using distance, fuel efficiency, and fuel price.
A Mileage and Fuel Cost Calculator estimates how much fuel a journey may use and its approximate cost.
Main Formulas
When mileage is expressed in kilometres per litre:
Fuel Needed = Distance ├╖ Mileage
Fuel Cost = Fuel Needed ├Ч Price per Litre
For example, a 300 km trip in a vehicle averaging 15 km/L requires about 20 litres. At тВ╣100 per litre, the estimated fuel cost is тВ╣2,000.
How to Use the Calculator
- Enter the distance of the trip.
- Enter expected mileage in km/L.
- Enter the current fuel price per litre.
- Calculate fuel required and estimated cost.
What Affects Mileage?
Actual mileage depends on traffic, speed, road surface, tyre pressure, load, maintenance, air conditioning, driving style, and weather. Manufacturer figures may differ from everyday use.
Estimate a Round Trip
For a return journey, include the total return distance rather than only the one-way distance. If you plan several stops or detours, add those kilometres too.
Make the Estimate More Useful
Use a realistic mileage based on your own recent driving, check the local pump price, and leave a buffer for traffic or route changes. The calculation excludes tolls, parking, maintenance, and other travel expenses unless entered separately.
This is a planning estimate, not a guarantee of actual fuel consumption.
