How much does it cost to charge an electric car?

At home in Quebec with Hydro-Québec rates (~$0.078/kWh), charging an EV costs roughly $1.40 per 100 km. At public fast-chargers, the cost is higher ($0.37–$0.61/kWh).

Why does the calculator add 35% for winter conditions?

In cold Canadian winters (-20°C), EV battery efficiency drops significantly due to cabin heating, battery thermal management, and increased rolling resistance. Natural Resources Canada data and real-world studies consistently show a 30–50% increase in consumption, with 35% being a reasonable average for a typical Quebec winter.

EV Cost Calculator — 8 Region Presets + 4 Currencies + Breakeven

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.

Eight region presets, 4-currency selector, and a break-even calculation

Eight region presets now load electricity rates and switch the currency automatically: Québec $0.08/kWh (CAD), Ontario $0.13, BC $0.10, California $0.30 (USD), Texas $0.13, New York $0.20, France €0.20, UK £0.27. Pick the one closest to your situation — or ignore them and type your actual bill rate. The 4-currency selector (CAD, USD, EUR, GBP) carries through to every output line, including the per-km cost.

The break-even section now shows the distance (km) and approximate years at your annual mileage where the EV's lower running cost offsets the price difference versus the gas car you're comparing. Enter the gas car's L/100km and $/L and the EV vs gas purchase price gap — the calculator does the rest. Charging speed and grid carbon intensity didn't make this version.

Frequently Asked Questions

How much does it actually 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.
