Charging costs in Ontario
Ontario’s optional Ultra-Low Overnight plan prices electricity differently by time of day. The preset uses the OEB’s 3.9¢/kWh overnight energy price; the standard TOU off-peak preset is 9.8¢/kWh. Those are not complete bill rates.
For a better estimate, use the incremental cost from your own bill and include a buffer for charging losses. Price any public fast charging separately at the network’s posted rate.

The starter input uses EIA’s July 2026 national residential average revenue of 18.31¢/kWh. It is a benchmark, not a utility quote: prices, rate structures, taxes and demand charges vary by state and provider.
Use the marginal rate from your own bill, add a buffer for charging losses and price any public fast charging separately. Source [6]
Maintenance differences
A battery-electric vehicle does not need engine oil changes, spark plugs or an exhaust system. Both vehicles still need tires, suspension work, cabin filters and other wear items; EV tire wear can vary with vehicle weight, power and driving style.
Rather than assuming a universal percentage, enter your own annual dollar difference using service schedules, warranty terms and local labour rates for the two exact models.
Winter range reality
Cold batteries, cabin heating, snow, winter tires and short trips can push energy use above the label figure. Avoid applying one blanket “winter penalty” to every EV: temperature, route, heat-pump equipment, preconditioning and parking conditions all matter.
Run a second scenario with a higher kWh/100 km or kWh/100 mi input. For trip planning, preserve a practical reserve and check the vehicle maker’s cold-weather guidance.
Canadian fuel ratings
Natural Resources Canada’s EnerGuide label reports model-specific consumption. For gasoline vehicles, the combined rating is in L/100 km. Use your trip computer if your real-world average differs. Sources [2]–[3]
Annual energy(annual km ÷ 100) × consumption × unit price
US fuel economy data
EPA and the Department of Energy publish model-specific MPG, MPGe and energy-use figures at FuelEconomy.gov. Use the combined MPG and kWh/100 mi figures for the exact vehicles, or your own measured averages. Source [8]
Annual energy(annual miles ÷ MPG) × gas price; (miles ÷ 100) × kWh/100 mi × rate
Canadian incentive landscape
iZEV is closed. Transport Canada says the former program closed March 31, 2025.
Transport Canada’s successor is the Electric Vehicle Affordability Program (EVAP), which began in 2026. Eligibility depends on the purchase or lease, vehicle, dealer participation and available funding.
The rebate field defaults to $0. Confirm the current program rules and transaction-specific amount on Transport Canada’s official pages before entering anything. Sources [4]–[5]
US incentive landscape
Federal credits changed. The IRS says the clean vehicle credits are not available for vehicles acquired after Sept. 30, 2025.
The New Clean Vehicle Credit, Previously-Owned Clean Vehicle Credit and Qualified Commercial Clean Vehicle Credit all have acquisition-date rules. State, local and utility programs may differ.
The incentive field defaults to $0. Check the IRS and any relevant state or utility program for the exact transaction before entering an amount. Source [9]
