EV Cost Calculator
Enter your numbers, see your savings instantly. Electric vs gasoline, no guesswork.
How It Works
This calculator multiplies your inputs to estimate driving costs. For electricity: distance × consumption (kWh/100km) × rate ($/kWh). For gasoline: distance × consumption (L/100km) × price ($/L). The difference is your savings.
Monthly and annual estimates are projected from your trip frequency. All calculations are transparent — no hidden assumptions, no projections beyond simple multiplication.
Important Disclaimer
These results are estimates based on the values you enter, not guarantees. Actual consumption varies with temperature, driving style, terrain, vehicle condition, battery age, and use of heating/AC. The preset rates shown are approximate and may not reflect your current billing. Always verify rates with your electricity provider.
Frequently Asked Questions
How much does it cost to charge an EV at home in Quebec?
With Hydro-Québec's residential Rate D (~$0.078/kWh), charging an EV costs roughly $1.40 per 100 km for a typical sedan (18 kWh/100km). For 20,000 km/year, that's about $280/year in electricity — compared to ~$2,975 in gasoline (8.5 L/100km at $1.75/L).
Why does the winter toggle add 35% to consumption?
In cold Canadian winters (-20°C and below), EV batteries lose efficiency due to three main factors: (1) cabin heating draws directly from the battery (unlike gas engines that use waste heat), (2) the battery management system uses energy to keep the cells at operating temperature, and (3) cold air increases rolling resistance and reduces regenerative braking efficiency. Natural Resources Canada data and real-world studies (including AAA and Norwegian Automobile Federation tests) consistently show a 30–50% increase in consumption in winter conditions. We use 35% as a reasonable middle-ground average for a typical Quebec winter.
Are these results guaranteed?
No. This is a calculator, not an oracle. It multiplies the numbers you provide — nothing more. Your actual costs depend on many factors we can't predict: driving habits, terrain, vehicle age, battery degradation, and real-time energy prices. Use the results as a reasonable estimate, not as a financial commitment.
Where do the preset electricity rates come from?
The preset rates are approximate averages: Hydro-Québec Rate D (~$0.078/kWh, among the lowest in North America), Ontario average (~$0.13/kWh including time-of-use), BC Hydro (~$0.10/kWh). These rates change — always verify with your provider. You can enter any custom rate.
