EV vs Diesel vs CNG Cost Calculator

Fuel and energy costs play a major role in the total cost of owning a vehicle. Whether you're considering an electric vehicle, a diesel car, or a CNG-powered model, understanding the long-term running costs can help you make a smarter purchase decision.

The EV vs Diesel vs CNG Cost Calculator lets you compare the estimated operating expenses of all three fuel types in one place. By entering your daily driving distance, local fuel and electricity prices, and vehicle efficiency figures, you can see how much each option may cost on a monthly and annual basis.

Unlike basic comparison tools that focus on only two fuel types, this calculator provides a comprehensive side-by-side analysis, making it easier to identify the most economical option for your driving needs.

How the EV vs Diesel vs CNG Cost Calculator Works

The calculator takes four inputs per fuel type and returns a monthly running cost. Enter your data once and all three comparisons populate together.

For EVs

You’ll need your battery capacity in kWh, your electricity rate per unit, and your daily range. The calculator turns these into a monthly electricity spend. Battery size is the biggest driver of your monthly EV cost.

For Petrol, Diesel & CNG

Enter the fuel price per litre or per kg alongside your vehicle’s mileage figure. The cng cost calculator side uses CNG price per kg and your CNG km-per-kg figure. You get a direct monthly comparison for all three fuel types.

FAQs

How accurate is the EV vs Diesel vs CNG Cost Calculator?

The EV vs diesel cost calculator is as accurate as the numbers you enter. Use your city’s current fuel price and your vehicle’s real-world mileage. The results will be close to your actual monthly spend.

How does battery capacity (kWh) affect my EV monthly running cost?

Directly. A bigger battery means more range but higher charge costs. If your daily commute is under 50 km, an EV often works out cheaper per month.

Is this calculator useful for fleet owners or only individual CNG car buyers?

Both. Fleet owners can run numbers across a vehicle category to check whether switching fuel types makes sense at scale. Individual buyers can use it for their own commute.

Can I use this calculator to decide whether to convert my existing petrol car to CNG?

Yes. Enter your current petrol mileage and the CNG mileage figure from your service centre. The calculator shows whether the monthly saving covers the conversion cost.

How is this calculator different from a general fuel cost calculator?

A general fuel cost calculator handles one fuel type at a time. This one compare EV, diesel, and CNG in a single run. That’s more useful when you’re still deciding on a fuel type.
