The rise of electric vehicles has made it more important than ever for drivers to understand whether switching from a petrol or diesel car to an EV is financially beneficial. To help you make smarter decisions, we created a free EV Cost & Savings Calculator that instantly compares your current fuel expenses with electric car charging costs.
This guide will show you exactly how to use it, what each field means, and how to interpret the results — even if you’ve never done such calculations before.
🔋 What This Calculator Does
The EV Cost & Savings Calculator helps you:
- Compare fuel car cost vs electric car cost
- Estimate monthly & yearly savings
- See your break-even period if you buy an EV
- Analyse “What-If” scenarios like rising fuel prices
- Get AI-style insights based on your driving habits
Everything runs instantly inside your browser — with zero login, zero tracking, and zero APIs.
🧠How to Use the EV Cost & Savings Calculator (Step-by-Step)
Step 1: Choose Your Currency
At the top of the form, select your preferred currency (default is $).
You can use:
- $ USD
- € EUR
- ÂŁ GBP
- â‚ą INR
- AED, AUD, CAD, etc.
This ensures all costs and savings appear in your local value.
Step 2: Enter Your Daily Driving Distance
Type how many kilometres (or miles converted to km) you drive on an average day.
Examples:
- 20 km/day → City driver
- 40–60 km/day → Typical office commuter
- 100+ km/day → Long-distance driver
This number is important because both fuel cost and EV charging cost depend on distance travelled.
Step 3: Enter Your Local Fuel Price
Input the cost of petrol or diesel per litre in your region.
Examples:
- USA: $0.80–$1.20 per litre
- India: ₹95–₹110 per litre
- Europe: €1.60–€2.00 per litre
You can check updated fuel prices from your city’s official website.
Step 4: Enter Your Car’s Mileage
Enter how many kilometres your current car travels per litre (km/L).
Examples:
- Small petrol car: 15–18 km/L
- SUV petrol: 10–12 km/L
- Diesel sedan: 18–22 km/L
This helps calculate your exact monthly fuel spending.
Step 5: Enter Electricity Price (Per kWh)
Add your electricity rate, which you can find on your household bill.
Typical rates:
- USA: $0.12–$0.28 per kWh
- India: ₹7–₹12 per kWh
- UK/EU: £0.30–£0.45 per kWh
The calculator uses this to estimate your monthly EV charging cost.
Step 6: Select Your EV Model
Choose from preloaded electric car models such as:
- Tesla Model 3
- Tesla Model Y
- Hyundai Ioniq 5
- Nissan Leaf
- Tata Nexon EV
- MG ZS EV
OR
Select Custom EV and manually enter energy consumption (kWh per 100 km).
Step 7: Enter Extra EV Cost (Optional)
If you want to know the break-even point, enter:
EV On-Road Price – Your Current Car Value
Example:
EV costs $40,000
Your current car sells for $15,000
→ Extra cost = $25,000
The calculator will estimate how many months or years it will take to recover this through fuel savings.
Step 8: Click “Calculate Savings”
Once all fields are filled, click the ⚡ Calculate Savings button.
You will instantly see:
- đź’° Monthly fuel car cost
- 🔌 Monthly EV charging cost
- 🟢 Monthly savings
- 🟣 Yearly savings
