Calculate cost per kilometre for electricity used to drive an average family car being charged in the home garage in Alberta

Using a representative 17 kWh per 100 km and an Alberta electricity energy rate of about 12.06¢/kWh, the electricity-only cost is:

[Cost per km \frac{17\ kWh}{100\ km}\times $0.1206/kWh

$0.0205/km]

Estimated cost

About 2.1¢ per kilometre, or approximately:

• $2.05 per 100 km
• $20.50 per 1,000 km
• $410 per 20,000 km

The 17 kWh/100 km estimate is representative of real-world mixed driving; typical electric cars may use roughly 12–20 kWh/100 km. Calgary’s regulated residential electricity energy rate is currently approximately 12.06¢/kWh, although competitive plans may be lower.^[1][2]

Range by vehicle efficiency

Vehicle consumption	Electricity-only cost
14 kWh/100 km	1.7¢/km
17 kWh/100 km	2.1¢/km
20 kWh/100 km	2.4¢/km
22 kWh/100 km	2.7¢/km

Including charging losses

Home charging typically requires somewhat more electricity from the wall than reaches the battery. Allowing for approximately 10% charging loss, the representative estimate becomes:

So a practical estimate is about 2.2–2.3¢ per kilometre, excluding fixed utility charges, taxes, vehicle depreciation, maintenance, and charger installation.
