Electricity is significantly cheaper than gasoline on a per-kilometre basis across every province and territory in Canada, but the actual savings depend on where you live, how far you drive, and how much of your charging happens at home versus away. This calculator uses your province’s residential electricity rate and your vehicle’s efficiency rating to give you a realistic monthly and annual cost estimate.
Enter your vehicle’s efficiency in kWh per 100 km, your weekly driving distance, and your province. If some of your charging happens away from home, adjust the home-charging percentage and pick the option that best matches your away-from-home habits, mostly slower public charging, mostly fast charging, or a mix, so that portion of the estimate reflects real-world costs too. Add your local gas price and your current vehicle’s fuel consumption for a direct fuel cost comparison.

Charging Cost Calculator FAQ
How accurate is this estimate?
It’s built to reflect your full monthly cost, not just home charging. The total blends your home charging cost, at your province’s rate or your own entered rate, with an estimate for any charging you do away from home. Actual results still vary with driving style and weather, but the number you get is meant to be a complete monthly figure, not a partial one.
Where do the electricity rates come from, and how often are they updated?
Home electricity rates come from provincial utility data and are reviewed quarterly. Away-from-home rates are typical Canadian public charging price ranges rather than numbers tied to a specific network, since actual public charging pricing varies by network and location. If you know your own away-from-home rate, enter it directly and it’s used instead of the typical estimate.
Does this include the cost of charging away from home?
Yes. Enter the percentage of your charging that happens at home, and the rest is priced using whichever away-from-home charging style you select (mostly slower public charging, mostly fast charging, or a mix), or your own rate if you know it. Both the monthly and annual totals reflect your full charging picture, not just the home portion.
Why might the efficiency number be different from what I’ve seen elsewhere?
This calculator runs on whatever kWh/100 km figure you enter. For an exact number, the hint links to the site’s Electric Vehicles page, which looks it up by year and trim using NRCan’s 5-cycle test rating, a rating that accounts for cold starts, air conditioning, and highway speeds. That figure tends to run higher than lab-only ratings you’ll see in some marketing materials or U.S. comparisons, since it reflects more realistic driving conditions.
Does this account for time-of-use electricity rates?
The home-charging portion uses a flat average rate for your province by default. If you’re in Ontario and mostly charge overnight, off-peak rates run around 7.6 cents per kWh, well below the provincial average, so entering that rate manually instead of the default will give you a more accurate number.
What if I don’t know my exact away-from-home charging rate?
You don’t need it. Pick whichever of the three options best matches how you usually charge away from home, mostly slower charging, mostly fast charging, or a mix, and the calculator uses a typical rate for that style. Only enter a specific rate if you actually know it from a network you use regularly.
