Formula Used

The power cost is calculated using the following formula:

Monthly Cost = (Usage × Rate) + Fixed Charge

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

This formula provides a straightforward way to estimate your electricity costs based on your usage and the rates charged by your electricity provider.

Worked Example

Let's calculate the cost for a household using 500 kWh of electricity on the On-Peak rate.

Monthly Cost = (500 kWh × $0.13/kWh) + $12.00 = $65.00 + $12.00 = $77.00

In this example, the household pays $0.13 per kWh for On-Peak electricity and a fixed monthly charge of $12.00. The total estimated monthly cost is $77.00.

Ontario Electricity Rates

Ontario electricity rates vary depending on the time of day and the type of customer. The most common rate types are:

On-Peak - Higher rates during peak demand periods (typically weekdays from 7 AM to 11 PM).
Mid-Peak - Moderate rates during less demanding periods (typically weekdays from 11 PM to 7 AM).
Off-Peak - Lower rates during non-peak periods (typically weekends and holidays).

The rates also differ for residential, small business, and large industrial customers. This calculator uses typical residential rates for simplicity.

Note: Actual rates may vary by provider and are subject to change. Always check with your electricity provider for the most current rates.
