Formula Used
The calculator uses the following formula to estimate your monthly electricity bill:
Where:
- Usage = Your monthly electricity consumption in kWh
- Rate per kWh = Variable rate based on your plan
- Fixed Monthly Charge = Flat fee for service
- Tax Rate = Current provincial and federal taxes
Note: Actual rates may vary based on your specific contract and Ontario Hydro's current pricing structure.
Worked Example
Let's calculate a monthly bill for a residential customer using 800 kWh of electricity.
Example Calculation:
Monthly Bill = (800 × $0.125) + $12 + (800 × 0.13) = $100 + $12 + $104 = $216
This example shows a residential customer with:
- Variable rate: $0.125 per kWh
- Fixed monthly charge: $12
- Tax rate: 13%
The total estimated monthly bill for this usage would be $216.
