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.
Are rates Canada-specific?
Yes. The tools use Canadian assumptions and are designed for provincial and utility differences.
Can I use estimates if I don’t have exact numbers?
Yes. Each calculator supports reasonable defaults, but real invoices will be more accurate.
Do these tools account for time‑of‑use or tiered rates?
Some calculators include rate structure inputs where available. If your plan has tiers or TOU, use the closest matching option.
Key definitions
kWh
Kilowatt-hour, the standard unit for electricity consumption.
Self-consumption
The portion of energy you use directly rather than export to the grid.
ROI
Return on investment, a measure of payback over time.
Rate
The price per unit of energy (e.g., $/kWh or $/L).
