Fuel Consumption Calculator 2026: Exact Liters & Cost Estimates

For a car with an average mileage of 15 kmpl, you will need 40 liters of petrol (600 / 15). At a 2026 price of ₹105/L, the total cost is approximately ₹4,200. Use our calculator with your vehicle's actual mileage for precise estimates. Remember to account for AC usage which can reduce efficiency by 15% in real-world conditions.

A diesel car averaging 20 kmpl requires 25 liters for a 500 km journey (500 / 20). With diesel prices often lower than petrol, this remains a preferred choice for long-distance 2026 travel. At ₹95/L, the total cost is approximately ₹2,375. Diesel vehicles typically offer better fuel efficiency, making them cost-effective for highway driving.

CNG vehicles typically have lower mileage than petrol (around 20-25% less). For a car with 12 km/kg CNG efficiency, you'll need 50 kg of CNG for 600 km. CNG is significantly cheaper than petrol (₹70-80/kg vs ₹105/L), making it the most economical option for city and highway driving in 2026.

Yes, AC usage reduces fuel efficiency by approximately 10-15% in real-world conditions. This is now a standard consideration in 2026 Indian vehicle testing protocols. Our calculator includes a "Real-World AC Toggle" that automatically reduces efficiency by 15% to reflect AC-on testing standards. For accurate trip planning, always account for AC usage, especially during summer months.

For a 500 km trip: A petrol car (15 kmpl) needs 33.33L at ₹105/L = ₹3,500. A diesel car (20 kmpl) needs 25L at ₹95/L = ₹2,375. Diesel saves approximately ₹1,125 for this distance. However, diesel cars have higher upfront costs. Calculate based on your annual driving to determine which is more economical for your usage pattern.

Enter your total trip distance and your vehicle's average mileage. Add current fuel price to get total cost. For example, a 1000 km trip with 15 km/L mileage requires 66.67 liters. At ₹105/litre, total cost is ₹7,000. Add 10-15% buffer for traffic and detours for realistic budget planning. Use our calculator for instant results with AC-on adjustments reflecting 2026 Indian testing standards.

Enter your total trip distance (1000 km) and your vehicle's average mileage. Add current fuel price to get total cost. For example, a 1000 km trip with 15 km/L mileage requires 66.67 liters. At ₹105/litre, total cost is ₹7,000. Add 10-15% buffer for traffic and detours for realistic budget planning. Use our calculator for instant results with AC-on adjustments.

AC-on testing is now a major 2026 trend in India. With AC on, most cars see a 10-15% reduction in fuel efficiency. For example, a car rated at 20 kmpl typically delivers 17-18 kmpl with AC on. High-mileage cars like Maruti Grand Vitara Strong Hybrid (27.97 kmpl) and Maruti Celerio (26.68 kmpl) maintain better efficiency even with AC, making them ideal for 2026 Indian driving conditions.

The Maruti Grand Vitara Strong Hybrid delivers an impressive 27.97 kmpl in 2026 ARAI testing with AC on. For a 600 km trip, it requires only 21.45 liters of petrol, costing approximately ₹2,252 at ₹105/L. This makes it one of the most fuel-efficient SUVs in India, ideal for long-distance travel and city commutes.

The Toyota Hyryder Strong Hybrid matches the Grand Vitara with 27.97 kmpl in real-world 2026 testing. For 500 km, it consumes 17.88 liters, and for 600 km, 21.45 liters. At ₹105/L, a 600 km trip costs ₹2,252. The strong hybrid system ensures excellent fuel efficiency even with AC on, making it perfect for Indian driving conditions.

Divide distance traveled by vehicle mileage. For example, if you travel 500 km with a vehicle that gives 15 km/L, fuel consumption is 500 ÷ 15 = 33.33 liters. Use our free calculator for instant results with multiple unit support (km/miles, km/L/MPG) and automatic cost calculation. The calculator includes AC-on adjustments for 2026 real-world testing standards.

Km/L (kilometers per liter) is the metric unit used in India, showing distance per liter. MPG (miles per gallon) is the imperial unit used in the US and UK. 1 MPG equals approximately 0.425 km/L. Our calculator supports both units and converts automatically, showing results in appropriate units based on your selection.

Yes, our calculator works for all vehicles including bikes, cars, SUVs, and commercial vehicles. Bikes typically have higher mileage (40-60 km/L), so fuel consumption will be lower for the same distance. Enter your bike's actual mileage for accurate calculations. The AC toggle doesn't apply to bikes, but you can still use the calculator for fuel cost estimation.

The calculator provides accurate estimates based on distance and mileage. Actual consumption may vary by 5-15% due to driving conditions, vehicle load, AC usage, and road conditions. Use your vehicle's actual average mileage (not manufacturer claims) and add 10-15% buffer for realistic trip planning. The AC toggle feature helps account for real-world efficiency losses.
