What is this CNG vs EV Savings Calculator?
The CNG vs EV Savings Calculator is a comprehensive vehicle cost comparison tool that helps you evaluate the long-term financial impact of choosing a Compressed Natural Gas (CNG) vehicle or an Electric Vehicle (EV). Both options offer lower operating costs than traditional petrol vehicles, but they differ in fuel prices, maintenance requirements, charging or refueling costs, and upfront purchase prices.
This calculator considers real-world driving conditions, including the fact that many factory-fitted or converted CNG vehicles consume a small amount of petrol during engine startup and warm-up. By comparing fuel costs, electricity charges, maintenance expenses, and vehicle purchase prices, the calculator estimates your monthly savings, yearly savings, and investment recovery period.
How it Works
The calculator analyzes the operating costs of both vehicle types based on your driving habits and local energy prices.
- Enter the CNG and petrol prices
- Input the electricity cost per kWh
- Provide your vehicle's CNG mileage and EV energy efficiency
- Enter your average monthly or yearly driving distance
- Add vehicle purchase prices or price difference, if applicable
- View running costs, total savings, and payback period
The calculator instantly compares the total ownership cost of both vehicle options.
Formula (with Example)
The calculator uses the following comparison formulas:
CNG Running Cost per KM = (CNG Price ÷ CNG Mileage) + Petrol Startup Cost per KM
EV Running Cost per KM = Electricity Cost × Energy Consumption per KM
Monthly Savings = CNG Cost − EV Cost
Payback Period = Additional Vehicle Cost ÷ Monthly Savings
Example:
- CNG Price: ₹75/kg
- CNG Mileage: 24 km/kg
- Petrol Startup Cost: ₹0.30/km
- Electricity Rate: ₹8/kWh
- EV Consumption: 0.15 kWh/km
- Monthly Distance: 2,000 km
The calculator estimates the total monthly operating cost for both vehicles and highlights the expected savings over months and years.

The Hidden Variables in CNG vs EV Savings
CNG and electric drivetrains present completely different operating models. A CNG vehicle requires a petrol allocation for startup thermal management cycles. This calculator integrates this logic to determine highly accurate return on investment (ROI) break-even timelines.
Whether you're buying your next vehicle or evaluating fleet operating costs, the CNG vs EV Savings Calculator helps you compare ownership expenses and choose the option that delivers the best long-term value.
Frequently Asked Questions
Find clear answers to common questions about this converter, accuracy, usage, and real-world applications.
What is a CNG vs EV Savings Calculator?
A CNG vs EV Savings Calculator compares the long-term ownership costs of a Compressed Natural Gas (CNG) vehicle and an Electric Vehicle (EV). It estimates running costs, monthly savings, and the time required to recover the higher purchase price of either option.
Why does the calculator include petrol consumption for CNG cars?
Many CNG vehicles use a small amount of petrol during engine startup and warm-up before switching to CNG. Including this cost provides a more realistic estimate of the vehicle's actual operating expenses.
What costs are compared in this calculator?
The calculator compares CNG fuel costs, petrol startup consumption, electricity charging costs, vehicle efficiency, driving distance, and purchase price differences to estimate total ownership costs.
Which is cheaper to run: CNG or an Electric Vehicle?
The answer depends on factors such as fuel prices, electricity rates, driving distance, vehicle efficiency, and maintenance costs. The calculator helps determine which option is more economical based on your specific inputs.
Does the calculator include maintenance costs?
The primary comparison focuses on energy and operating costs. However, you can also consider maintenance expenses separately, as EVs generally require less routine maintenance than CNG vehicles.
Can this calculator help me decide which vehicle to buy?
Yes, the calculator provides a detailed comparison of running costs, long-term savings, and investment recovery, making it easier to choose the vehicle that best suits your budget and driving habits.
Who can benefit from using this calculator?
This calculator is useful for daily commuters, families, taxi operators, ride-sharing drivers, delivery businesses, and commercial fleet owners who want to reduce transportation costs and compare alternative fuel options.
