Home calculators
Four calculators set up with your city's climate, 2026 energy prices, open rebates and provincial rules. Each one shows its formulas and sources, labels every assumption you can change, and keeps what you enter in your browser.
Home heating cost calculator
What heating, hot water and air conditioning cost at your local prices, and what each heating system would cost instead.
- Yearly heating cost for gas, oil, propane, electric, heat pump and wood systems
- Hot water and air conditioning costs
- Optional: scale it to your own bills
Insulation and upgrade payback calculator
Savings, rebates and payback for attic, wall and basement insulation, windows, air sealing and thermostat setbacks.
- Attic, walls, basement, windows, air sealing, thermostat
- Rebates that are open today, with their conditions
- Payback with conservative savings
Home health check
Radon results, winter humidity and window condensation, smoke and CO alarm rules, well water and mould.
- What your radon result means
- Winter humidity that keeps windows dry
- Smoke and CO alarms: the law and the recommendation
Appliance energy cost calculator
What your fridge, dryer, freezer and other appliances cost to run at your local electricity price, and what a newer model saves.
- Fridges, freezers, laundry, TVs, hot tubs, EVs
- Block heaters, with your city's cold nights
- What a newer model or a timer saves
How these calculators work
The numbers come from public sources we checked on October 8, 2026: NRCan's HOT2000 climate data and heating tables, Environment and Climate Change Canada's climate normals, utility rate schedules, Statistics Canada fuel prices, provincial fire codes and rebate program pages. Each page lists its sources.
Where a number has to be assumed, such as how much insulation a 1970s attic has, the calculator says so and lets you change it. Savings use the price of one more unit of energy, without fixed charges, which keeps them on the low side. An EnerGuide evaluation measures your house and replaces those assumptions.
