About Fuel Cost Calculator
The Fuel Cost Calculator helps you estimate total fuel expenses for any road trip. Whether you're planning a family vacation, daily commute, or business travel, know exactly how much you'll spend on fuel before you start driving.
Simply enter distance, fuel price, and your vehicle's mileage (km/l or liters/100km). The calculator instantly shows total fuel cost, liters needed, and cost per kilometer. Perfect for budgeting road trips and comparing vehicle efficiency.
How to Use This Fuel Cost Calculator
Step 1: Enter your trip distance in kilometers.
Step 2: Enter current fuel price per liter (₹/liter).
Step 3: Select fuel efficiency unit — km/liter or liters/100km.
Step 4: Enter your vehicle's mileage (e.g., 18 km/l or 8 L/100km).
Step 5: Click "Calculate Fuel Cost" to see total cost.
Step 6: Use the Reset button to clear all inputs and try different scenarios.
Why Use a Fuel Cost Calculator?
✓ Trip Budgeting
Plan your travel budget accurately. Know fuel costs before you start — no surprises. Compare costs across different routes or vehicles.
✓ Vehicle Comparison
Compare fuel costs between your cars. Decide which vehicle is more economical for long trips. Calculate savings potential.
✓ Carpool Savings
Divide total fuel cost by passengers. Show friends how much they save by carpooling. Split costs fairly without arguments.
✓ Business Reimbursement
Calculate exact fuel cost for business trips. Use for expense reports and client billing. Standard mileage rate alternative.
Fuel Economy Guide by Vehicle Type
| Vehicle Type | City (km/l) | Highway (km/l) | Combined (km/l) |
|---|---|---|---|
| Small Hatchback (800-1200cc) | 15-18 | 20-25 | 18-22 |
| Sedan (1200-1500cc) | 12-15 | 18-22 | 15-18 |
| SUV (1500-2000cc) | 8-12 | 14-18 | 10-15 |
| MUV/MPV (7-seater) | 8-11 | 13-16 | 10-13 |
| Motorcycle (100-150cc) | 35-45 | 45-55 | 40-50 |
Fuel Saving Tips for Better Mileage
- ✓Maintain proper tire pressure: Under-inflated tires increase fuel consumption by 3-5%. Check monthly.
- ✓Drive smoothly: Aggressive acceleration and braking wastes 10-30% fuel. Anticipate traffic flow.
- ✓Remove roof carriers: Empty roof racks increase drag, reducing mileage by 10-25% on highways.
- ✓Use A/C wisely: Above 80 km/h, A/C uses less fuel than open windows. Below 60 km/h, windows down saves fuel.
- ✓Reduce weight: Remove unnecessary items. Every 50 kg reduces mileage by 1-2%.
Fuel Price Comparison by Fuel Type (India)
| Fuel Type | Price Range (₹/liter) | Fuel Economy |
|---|---|---|
| Petrol | 95-110 | 15-20 km/l (cars) |
| Diesel | 85-95 | 18-25 km/l (cars) |
| CNG | 70-85 | 20-25 km/kg |
| Electric (₹/kWh) | 6-10 | 6-8 km/kWh |
Frequently Asked Questions
Fuel Cost = Distance × Fuel Price ÷ Mileage (km/l) or Distance × Fuel Price × Fuel Economy (l/100km). Our calculator handles both metrics.
Cars: 15-20 km/l (good), 20-25+ km/l (excellent). SUVs: 10-15 km/l. Motorcycles: 35-50 km/l. EVs: cost equivalent to 25-30 km/l.
EV cost = Distance × Electricity Rate (₹/kWh) ÷ Efficiency (km/kWh). EVs typically achieve 6-8 km/kWh. At ₹8/kWh, 100 km costs ~₹100-130 (vs ₹800-1000 for petrol). Use our EV mode for accurate estimates.
Highway mileage is 15-25% better than city due to fewer stops. Example: City 12 km/l → Highway 15 km/l. Use highway figures for road trips, city figures for daily commute. Our calculator uses combined average if not specified.
Double the one-way distance. Example: One-way 500 km → round trip 1000 km. Calculate fuel needed for 1000 km. For trips with different routes, calculate each direction separately.
Every 50 kg extra load reduces fuel economy by 1-2%. Roof cargo carrier reduces by 10-25% due to drag. A/C use reduces by 5-10%. Tire pressure 10% low reduces by 3-5%.
Optimal speed: 50-65 km/h (30-40 mph). Fuel efficiency drops rapidly above 80 km/h (50 mph). At 120 km/h (75 mph), you burn 20-30% more fuel than at 80 km/h. Use cruise control on highways.
Cost per person = Total fuel cost ÷ Number of passengers. Example: ₹2,000 trip cost, 4 persons → ₹500 each. You save 75% compared to driving alone. Our calculator shows per-person cost when you enter passenger count.
Idling consumes 0.5-2 liters/hour depending on engine size. A 1.5L engine idling for 10 minutes wastes ~150ml fuel ($0.18). Modern engines don't need warm-up. Turn off engine if stopped for more than 60 seconds.
Calculate separately for each vehicle, then sum total cost. Compare per-person cost to decide which vehicle is more economical. For business fleets, add maintenance cost (₹1-2/km) to total fuel cost.
