An electricity bill is not a fuel receipt.

Give electricity its own unit

NRCan’s fuel-consumption search tool supports an electricity-price input per kilowatt-hour. When making your own estimate, use a clearly identified electricity-use figure rather than treating kWh and litres as interchangeable.

Name the boundary

In this site’s calculator, the electric input means electricity paid for per 100 km. Use a wall-energy estimate that already accounts for charging losses, or treat the result as a simplified illustration. Do not add a second loss allowance to a figure that already includes it.

Calculate a transparent example

At 18 kWh/100 km over 12,000 km, the estimate is 2,160 kWh. With an illustrative rate of CAD $0.15/kWh, that is CAD $324. The difference from a gasoline example is only the difference between those assumptions; it is not a promised saving.

Keep complicated tariffs out of a simple box

A flat per-kWh input cannot represent every bill or public-charging arrangement. Add time-based fees, session charges, taxes or fixed costs separately when relevant. For a real decision, use your own provider’s current terms and vehicle documentation rather than the preset examples.
