Fuel Cost Calculator India – Petrol, Diesel, CNG & EV

Introduction: The story of one of my friends. Mr. Rajat, a 28-year-old software engineer from Gwalior, Madhya Pradesh, reached out to me last month. He was planning a round trip from Gwalior to Jaipur with his family and wanted to estimate how much fuel it would cost.

He had no idea how to factor in things like fuel type, route tolls, mileage, fuel price, or EV charging rates. So, I share with him a quick solution, the Ease Fuel Cost Calculator by Easemoney India.

He used it, and in minutes, he was able to:

Compare costs for Petrol, Diesel, CNG, and EV
Add toll fees and custom mileage
Plan multiple trip segments
Set custom fuel (petrol, CNG, Diesel, EV charging) rates for different cities

The result? He skipped using his diesel SUV and instead chose the family CNG hatchback, saving over ₹1,800 on the total journey. That’s the power of knowing your numbers.

Let’s begin this guide to better understand-

What Do You Mean by Fuel Cost in India?

Fuel cost in india has a simple meaning: the total amount spent on the fuel required to complete the journey distance. It works on daily commutes or long highway trips all over India.

Fuel cost depends on:

Fuel price per litre/unit (Petrol, Diesel, CNG, or EV)
Vehicle mileage (km/litre or km/unit)
Distance (kilometres works in india)
Fuel efficiency or mileage (depends on terrain, load, traffic, vehicle speed, and AC usage)

Sample Table for the fuel cost of each fuel type in india

For a better idea, here is an Estimated Fuel Cost for a 100 KM Journey in Bhiwadi (a Tier 2 city in Rajasthan)

Why You Need a Petrol Cost Calculator in India

In india, the fuel prices fluctuate daily. A Petrol price in Mumbai might be ₹108/litre, while in Haryana it may be ₹96/litre. EV charging also changes: public DC fast charging can cost up to ₹22/unit + GST taxes, while slow home charging may cost just ₹7/unit.

Here are the other reasons why it is essential:

Car mileage varies by traffic, weather, and AC usage
Fuel efficiency drops over time
CNG and EV infrastructure isn’t the same everywhere
Tolls and route conditions matter

What Is the Manual Formula to Calculate Petrol Cost?

If you decide to calculate by using a pen and paper, here is the formula you can use to find the total fuel cost of your trip in India –

Formula: Fuel Cost = Distance (in KM) ÷ Mileage (KM/L or KM/unit) × Fuel Price (₹)

Example:

Distance = 200 KM
Mileage = 20 KM/L
Fuel Price = ₹100/L

Fuel Cost = 200 ÷ 20 × 100 = ₹1,000

Always compare fuel types before trips longer than 100 KM.
For EVs, prefer home charging over public DC to save 70% cost and GST Taxes. Also, it’s good for the battery of your EV.
Maintain your car’s mileage regularly to avoid underestimation
Use the planner for wedding travel or group vacations.
