Formula Used
The calculator uses the following formula to estimate your monthly electricity cost:
Monthly Cost Formula
Monthly Cost = (Consumption × Rate) + Fixed Charge
Where:
- Consumption is your monthly electricity usage in kWh
- Rate is the cost per kWh for your selected rate plan
- Fixed Charge is the monthly service fee for your plan
Note: Actual costs may vary based on your specific Ontario Hydro contract and any additional fees or credits.
Worked Example
Let's calculate the cost for a household using 800 kWh on the On-Peak rate plan:
Example Calculation
Consumption: 800 kWh
Rate Plan: On-Peak (12.5 cents/kWh)
Fixed Charge: $12.00
Calculation: (800 × $0.125) + $12.00 = $100.00 + $12.00 = $112.00
Estimated Monthly Cost: $112.00
This example shows that for 800 kWh of electricity, the estimated monthly cost would be $112.00 on the On-Peak rate plan.
