Electricity costs vary significantly in Ontario due to tiered pricing structures and fluctuating rates. This calculator helps you estimate your monthly electricity bill based on your consumption and the current rates from Ontario's Independent Electricity System Operator (IESO).
How to Use This Calculator
To calculate your estimated electricity cost in Ontario:
- Enter your monthly electricity consumption in kilowatt-hours (kWh)
- Select your electricity rate tier (On-Peak, Mid-Peak, or Off-Peak)
- Click "Calculate" to see your estimated monthly cost
The calculator uses Ontario's current average rates for residential customers. For more precise estimates, you may need to check your specific electricity provider's rates.
Formula and Assumptions
The cost of electricity is calculated using the following formula:
Assumptions:
- Rates are based on Ontario's average residential electricity prices
- All calculations are for monthly estimates
- Taxes and fees are not included in the calculation
- Rates are subject to change by your electricity provider
Worked Example
Let's calculate the cost for a household using 500 kWh of electricity at the On-Peak rate of $0.132/kWh:
This example shows that a household using 500 kWh of electricity at the On-Peak rate would pay approximately $66 per month.
Ontario's Tiered Electricity Rates
Ontario electricity rates are divided into three tiers based on when the electricity is used:
| Tier | Time Period | Average Rate (2023) |
|---|---|---|
| On-Peak | Weekdays 7:00 AM - 11:00 PM | $0.132/kWh |
| Mid-Peak | Weekdays 11:00 PM - 7:00 AM | $0.084/kWh |
| Off-Peak | Weekends all day | $0.065/kWh |
Your electricity bill will reflect the rates for the specific times you used electricity during the billing period.
Tips to Reduce Electricity Costs
Here are some practical ways to lower your electricity bills:
- Use energy-efficient appliances with the Energy Star label
- Unplug devices when not in use to eliminate "vampire" power draw
- Adjust your thermostat by 2°C in winter and 1°C in summer
- Use natural light during the day instead of artificial lighting
- Install smart power strips to cut off power to unused outlets
- Consider solar panels if you have roof space available
Reducing your electricity consumption by 10% could save you hundreds of dollars each year.
