Who this is for: Canadian homeowners comparing energy costs, fuel choices, and equipment payback.
- Estimating bills from recent invoices or typical usage.
- Comparing upgrade options like heat pumps or solar.
Start here
- 1. If you have a bill, start with Electricity or Propane costs.
- 2. For equipment decisions, use Heat pump ROI or Solar ROI.
- 3. For outage planning, estimate Generator fuel cost.
Data sources & assumptions
Calculators use typical Canadian billing structures and rates. Supplier charges can vary; use your bill whenever possible.
FAQ
Do these tools include delivery or service fees?
Some calculators include common fees, but local service charges can vary. Use your bill or supplier details when available.
