Fuel Cost Calculator – Free Online Petrol & Gas Trip Cost Estimator
What is a Fuel Cost Calculator?
A fuel cost calculator is an online tool that estimates the total fuel expense for any trip by calculating how many litres or gallons of fuel your vehicle will consume based on its mileage and the distance you plan to travel.
It is an essential tool for:
- Drivers planning road trips or long-distance travel
- Daily commuters calculating monthly fuel budgets
- Cab and taxi drivers tracking trip-by-trip fuel costs
- Fleet owners and logistics managers managing vehicle expenses
- Travellers comparing petrol vs diesel vs CNG running costs
Fuel Cost Formula – How is Trip Fuel Cost Calculated?
Our calculator uses this simple, industry-standard formula:
Total Fuel Cost = Fuel Needed × Fuel Price per Litre
Step-by-Step Example
You are driving from Delhi to Agra (220 km) in a car with 15 km/L mileage and petrol at ₹103/L:
- Fuel Needed = 220 ÷ 15 = 14.67 litres
- Total Cost = 14.67 × ₹103 = ₹1,511
- Return Trip Cost = ₹1,511 × 2 = ₹3,022
- Cost per km = ₹1,511 ÷ 220 = ₹6.87/km
