Understanding your power consumption is essential for managing your electricity bills and reducing your environmental impact. This calculator helps you estimate your monthly electricity usage in Ontario, based on your appliance usage and electricity rates.
How to Use This Calculator
To calculate your power consumption in Ontario:
- Enter the number of hours you use each appliance daily

The calculator provides a breakdown of your consumption by appliance and visualizes your usage pattern.
Formula Used
Daily Consumption (kWh): (Hours per day × Power rating (kW)) ÷ 1000
Monthly Consumption (kWh): Daily Consumption × 30
Monthly Cost ($): Monthly Consumption × Electricity rate ($/kWh)
The calculator sums these values for all appliances to provide a total estimate.
Worked Example
Suppose you have:
- A refrigerator (0.5 kW, used 24 hours/day)
- A TV (0.1 kW, used 4 hours/day)

With an electricity rate of $0.15/kWh:
| Appliance | Daily kWh | Monthly kWh |
|---|---|---|
| Refrigerator | 1.44 | 43.2 |
| TV | 0.096 | 2.88 |
| Electric Heater | 1.44 | 43.2 |
| Total | 3.00 | 89.28 |
Monthly cost: $13.39
