EV vs Petrol Calculation Guide (Step-by-Step)
Here is how to calculate EV vs petrol cost manually:
Step 1: Calculate EV Cost
Formula:
Example:
Distance = 1000 km/month, EV consumption = 15 kWh/100 km, Electricity price = $0.15/kWh
EV Cost = (1000 × 15 ÷ 100) × 0.15 = $22.5 per month
Step 2: Calculate Petrol Cost
Formula:
Example:
Distance = 1000 km, Mileage = 15 km/l, Petrol price = $1.2/l
Petrol Cost = 1000 ÷ 15 × 1.2 = $80 per month
Step 3: Calculate Savings
Savings = 80 − 22.5 = $57.5 per month
EV vs Petrol Conversion Chart
| Distance (km/month) | EV Cost ($) | Petrol Cost ($) | Savings ($) |
|---|---|---|---|
| 500 | 11.25 | 40 | 28.75 |
| 1000 | 22.5 | 80 | 57.5 |
| 1500 | 33.75 | 120 | 86.25 |
| 2000 | 45 | 160 | 115 |
| 3000 | 67.5 | 240 | 172.5 |
Assumptions: EV: 15 kWh/100 km, $0.15/kWh | Petrol: 15 km/l, $1.2/l
Vehicle-to-Grid (V2G) Bidirectional Integration
Vehicle-to-Grid (V2G) technology allows EV batteries to export power back to the grid during peak demand hours, serving as virtual power plants. Sizing bidirectional systems requires coordinating grid inverter grid synchronization and battery charging limits:
While V2G provides grid stability and peak shaving credits, it increases battery cycle wear. Managing charge/discharge thresholds is critical to balancing financial returns with battery lifespan under continuous EV vs Petrol setups.
FAQs About EV vs Petrol Calculator
An EV vs petrol calculator is an advanced analytical tool specifically engineered to comprehensively compare the ongoing running costs of modern electric vehicles against traditional gasoline cars. It simultaneously analyzes driving distances, energy consumption, and local electricity tariffs.
Yes, driving a fully electric vehicle is typically significantly cheaper than operating a conventional petrol car on a per-kilometer basis. Because electric motors are exceptionally efficient, the cost of electricity required to travel is generally a tiny fraction of the cost of liquid fuel.
The primary financial drivers include your total driving distance, local electricity rates including peak home tariffs, current petrol prices at pump stations, and the relative energy efficiencies of both vehicles. All of these elements combine to determine your total automotive expenditure.
You can easily and accurately project your comprehensive annual financial savings with this tool. Simply calculate your average monthly financial savings using the provided interface and multiply that exact figure by twelve to receive a highly accurate estimation of your yearly cost reduction.
Yes, the specific method you choose for charging will significantly impact your total operating expenses. Charging your vehicle at home using standard overnight residential utility rates is highly cost-effective, whereas relying exclusively on public fast chargers involves premium pricing.
Conclusion
An ev vs petrol calculator gives clear insights into running costs and savings. It helps you make better financial and environmental decisions. Use it regularly to track fuel cost changes and maximize savings.
