Fuel Cost Calculator India – Calculate Petrol, Diesel & CNG Expenses

Fuel prices in India vary widely across states and cities, and even small daily commutes can add up to a significant monthly expense. Whether you ride a two-wheeler, drive a hatchback, SUV, or use a CNG vehicle, knowing your exact fuel cost helps you plan better and avoid surprises.

The Motors77 Fuel Cost Calculator helps you estimate your daily, monthly, and yearly fuel expenses based on your city’s fuel price, your vehicle’s mileage, and your average daily distance. It’s built specifically for Indian driving conditions and works for petrol, diesel, and CNG vehicles.

Use the calculator below to instantly understand how much fuel really costs you.

How to Use the Fuel Cost Calculator

Using the Motors77 fuel cost calculator is simple and takes less than a minute.

First, select your city so the calculator can fetch the current local fuel price. Fuel rates differ across India due to state taxes and transportation costs, so city selection is important for accurate results.

Next, choose your fuel type petrol, diesel, or CNG depending on what your vehicle uses. The calculator automatically adjusts the cost unit based on your selection.

Enter the average distance you travel in a day. This can include your daily office commute, school runs, errands, or regular travel. For example, if you travel 20 km one way to work, your daily distance would be 40 km.

Finally, enter your vehicle’s mileage. Mileage refers to how many kilometres your vehicle travels per litre of fuel (or per kilogram in case of CNG). You can find this information in your vehicle’s owner manual or manufacturer specifications. For more realistic estimates, consider using real-world mileage rather than claimed figures.

Once entered, the calculator instantly shows your estimated daily, monthly, and yearly fuel costs.

Typical Mileage Reference (India)

Mileage varies by vehicle type, engine size, traffic conditions, and driving style. As a general reference:

Two-wheelers usually deliver between 40 and 60 km/l.
Petrol hatchbacks average around 15 to 22 km/l.
Sedans typically return 12 to 18 km/l.
SUVs usually range from 10 to 15 km/l.
CNG vehicles generally deliver 20 to 30 km/kg.

These figures are indicative and real-world mileage may be lower depending on traffic, load, and air-conditioner usage.

Why Calculating Fuel Cost Matters

Fuel is often the second-largest ownership expense after vehicle EMI payments. Tracking it accurately helps you manage your monthly budget more effectively and understand where your money is going.

If you are planning to buy a new car, the calculator helps compare fuel costs between different body styles and fuel types. A vehicle with slightly higher mileage can save a substantial amount over several years, even if its upfront cost is higher.

For road trips, estimating fuel cost in advance helps plan travel budgets better. Knowing approximate expenses also helps compare alternatives such as public transport, carpooling, or choosing a more fuel-efficient vehicle for long journeys.

The calculator also shows how fuel price changes impact your expenses. Even a small ₹3–₹5 increase per litre can significantly affect yearly fuel spending, especially for high daily usage.

Frequently Asked Questions

How accurate are the fuel prices shown?
Fuel prices are updated periodically based on official rates from major oil marketing companies. Actual prices may vary slightly depending on the fuel station and local levies.

Why do fuel prices differ between cities?
Fuel prices in India vary mainly due to state-level VAT, transportation costs, and local taxes. This is why petrol and diesel can be significantly cheaper in one state compared to another.

How do I find my vehicle’s mileage?
You can check the owner’s manual or manufacturer website for ARAI-certified mileage. For realistic results, use your real-world mileage, which is typically 15–20% lower than claimed figures.

Is CNG cheaper than petrol or diesel?
CNG usually costs less per kilometre compared to petrol and diesel. However, availability of CNG stations and slightly reduced boot space are factors to consider.

Can this calculator be used for commercial vehicles?
Yes. The calculator works for any vehicle type, including taxis, trucks, buses, and auto-rickshaws. Simply enter the appropriate mileage.
