Use our free electric vs petrol cost calculator Romania to find out exactly how much you would save by driving a Tesla instead of a petrol car. With fuel prices in Romania currently at €1.62/litre and household electricity at €0.19/kWh, the difference in running costs is significant — but the exact saving depends on how much you drive, where you charge, and what car you’re comparing against.
This electric vs petrol cost calculator lets you enter your own numbers — annual km, your electricity tariff, your current fuel consumption — and calculates your real cost per km and annual savings instantly. Based on real Romanian prices, the same data behind our Tesla vs Petrol article and used by drivers tracked on Voltayze.
How to use this calculator
Enter your annual kilometres, your home electricity tariff and the percentage of charging you do at home versus at a Supercharger. On the petrol side, enter your car's fuel consumption and the current pump price. Hit Calculate and you'll instantly see your cost per km for each option, your annual saving, and a projection over 1, 3, 5 and 10 years.
Why are the default values set to Romanian prices?
The calculator comes pre-loaded with current Romanian prices — €1.62/litre for petrol and €0.19/kWh for home electricity. These reflect April 2026 averages. You can change any value to match your exact tariff or location.
Does the calculator include maintenance costs?
Yes — both panels include an annual service cost field. The defaults are set to €200 for a Tesla (realistic for Romania) and €500 for a petrol car. Adjust these to match your actual servicing costs for a more accurate comparison.
How accurate is this calculator?
The calculator uses real consumption figures and current Romanian energy prices. For the most accurate result, use your own electricity tariff from your energy bill and your car's real-world consumption rather than the manufacturer figure. Voltayze users can find their exact kWh/100km figure in their Voltayze dashboard.
