The calculator uses current Ontario electricity rates and provides a clear breakdown of your costs. You can adjust your inputs to see how different usage levels and plan types affect your electricity bill.

Formula Used

The calculator uses the following formula to estimate your monthly electricity cost:

Monthly Cost = (Usage × Rate) + Fixed Charge

Usage - Your monthly electricity consumption in kWh
Rate - The cost per kWh for your selected plan type
Fixed Charge - A monthly service fee for your electricity plan

For Time-of-Use plans, the calculator applies different rates to On-Peak, Mid-Peak, and Off-Peak usage periods.

Worked Example

Let's calculate the cost for a household with 500 kWh of monthly usage on an On-Peak plan:

Monthly Cost = (500 kWh × $0.12/kWh) + $12.00 = $72.00

Usage: 500 kWh
Rate: $0.12/kWh (On-Peak)
Fixed Charge: $12.00

This example shows that a household using 500 kWh on an On-Peak plan would pay approximately $72 per month for electricity.
