Fuel Cost Calculator for Road Trips
Planning a road trip budget starts with knowing your fuel cost. This calculator factors in your vehicle's actual mileage, current fuel prices, and trip type to give an accurate fuel budget — plus a per-person split for group trips.
Why Mileage Varies From the Spec Sheet
Manufacturer-claimed mileage figures are tested under controlled conditions and rarely match real-world performance. Highway driving at steady speed typically achieves closer to claimed mileage, while city driving with frequent stops, AC usage, and traffic can reduce mileage by 15-25%.
Beyond Fuel — Total Trip Budget
Remember that fuel is just one component of total trip cost. Long highway trips in India also typically involve toll charges (often ₹500-2000+ depending on route and distance), parking fees, and any food or overnight stops.
Frequently Asked Questions
Should I use city or highway mileage for trip planning? +
For highway road trips, use your vehicle's highway/ARAI-rated mileage as it's closer to actual performance. For trips involving significant city driving, reduce the mileage figure by 15-20% for a more realistic estimate.
Does AC usage significantly affect fuel consumption? +
Yes — continuous AC usage can reduce mileage by 5-10%, more in stop-and-go city traffic where the engine works harder at lower speeds while still running the AC compressor.
How accurate is splitting cost by passenger count? +
This is a simple equal-split calculation. For fairer cost-sharing on trips with varying distances dropped off at different points, consider calculating per-segment costs instead of a flat per-person split.

Fuel Cost Formula
Fuel Cost = (Distance ÷ Mileage) × Fuel Price per litre
Mileage varies by speed, AC usage, load, road conditions. City mileage is typically 20–30% lower than highway mileage.
Worked Example
Mumbai to Pune (150 km). Car mileage = 15 km/litre. Petrol price = ₹106/litre. Fuel = 150 ÷ 15 × ₹106 = ₹1,060 one way. Return trip = ₹2,120. Add ₹300 toll = ₹2,420 total.
Tips
- Drive at 60–80 kmph for best fuel efficiency on highways
- Turn off AC when it's not needed — AC increases fuel consumption by 10–15%
- Compare with train/bus for long trips — often cheaper and less tiring
