Formula Used
The electricity cost is calculated using the following formula:
Total Cost = (Usage × Rate) + (Usage × Rate × HST)
Where:
- Usage = Monthly electricity consumption in kWh
- Rate = Cost per kWh for the selected rate plan
- HST = Ontario Harmonized Sales Tax (13%)
This formula accounts for both the base electricity cost and the applicable provincial sales tax.
Worked Example
Let's calculate the electricity cost for a home using 500 kWh/month on the Ontario Energy Board (OEB) rate plan:
Example Calculation:
1. Base cost: 500 kWh × $0.12/kWh = $60.00
2. HST: $60.00 × 13% = $7.80
3. Total cost: $60.00 + $7.80 = $67.80
This example shows the total monthly cost for 500 kWh of electricity in Ontario.
