Formula and Assumptions
The Ontario Energy Cost Calculator uses the following formula to estimate your electricity bill:
Energy Cost Formula
Total Cost = (Monthly Usage × Rate per kWh) + Fixed Monthly Charge + (Monthly Usage × Tax Rate)
Where:
- Monthly Usage = Your monthly electricity consumption in kWh
- Rate per kWh = The cost per kilowatt-hour for your selected provider
- Fixed Monthly Charge = The base monthly fee for your energy plan
- Tax Rate = The applicable Ontario energy tax rate (currently 13%)
Important Notes
This calculator provides an estimate based on average rates and assumptions. Actual costs may vary depending on your specific usage patterns, time of year, and any promotions or discounts offered by your energy provider.
Worked Example
Let's calculate the energy cost for a home with 500 kWh of monthly usage using Hydro One rates:
- Monthly Usage = 500 kWh
- Rate per kWh = $0.12
- Fixed Monthly Charge = $12
- Tax Rate = 13%
Calculation:
Example Calculation
Total Cost = (500 × $0.12) + $12 + (500 × $0.12 × 0.13)
= $60 + $12 + $7.80
= $80.80
So, the estimated monthly cost would be $80.80.
Energy Cost Comparison
Here's a comparison of estimated monthly costs for different energy providers in Ontario:
| Provider | Rate per kWh | Fixed Monthly Charge | Estimated Cost (500 kWh) |
|---|---|---|---|
| Hydro One | $0.12 | $12 | $80.80 |
| Enbridge | $0.13 | $15 | $83.55 |
| Toronto Hydro | $0.11 | $10 | $75.30 |
This comparison shows that Toronto Hydro offers the lowest estimated cost for 500 kWh of usage, while Enbridge has the highest fixed charge.
