Before any road trip, three numbers are all you need to estimate what fuel will cost: the distance you’ll drive, your vehicle’s mileage in km/l, and today’s fuel price per litre.
The calculation
Litres needed = Distance ÷ Mileage. Total cost = Litres × Price per litre. A 320 km trip in a car doing 16 km/l at ₹103.5/litre needs 20 litres, costing roughly ₹2,070 — before tolls or detours.
Don’t know your mileage?
Use the Mileage Calculator with figures from your last full tank to find your real-world km/l before estimating a new trip’s cost.
Ways to reduce the actual cost
- Maintain a steady cruising speed rather than frequent acceleration and braking
- Check tyre pressure before setting off — low pressure quietly increases fuel use
- Plan a route that avoids heavy stop-start traffic where a reasonable alternative exists
- Travel light — extra weight costs mileage on longer trips
