Formula Used
The electricity cost is calculated using the following formula:
Total Cost = (Usage × Rate) + (Usage × Rate × Tax Rate)
Where:
- Usage = Monthly electricity usage in kWh
- Rate = Cost per kWh for your selected rate plan
- Tax Rate = Current Ontario electricity tax rate (13%)
This formula accounts for both the base cost of electricity and the applicable taxes in Ontario.
Worked Example
Let's calculate the monthly electricity cost for a household using 500 kWh of electricity on the Ontario Energy Board (OEB) rate plan.
Example Calculation
Usage: 500 kWh
Rate: $0.12 per kWh (OEB rate)
Tax Rate: 13%
Calculation: (500 × $0.12) + (500 × $0.12 × 0.13) = $60 + $7.80 = $67.80
Total Monthly Cost: $67.80
This example shows that a household using 500 kWh of electricity on the OEB rate plan would pay approximately $67.80 per month.
Interpreting Results
The calculator provides several key pieces of information:
- Base Cost: The cost of electricity before taxes
- Tax Amount: The amount of tax applied to your electricity usage
- Total Cost: The final amount you'll pay each month
Use this information to compare different rate plans, estimate your energy costs, and make informed decisions about your electricity usage.
