How to Use This Calculator

To estimate your Ontario Hydro bill:

Enter your total electricity usage in kilowatt-hours (kWh) for the billing period

If using Time-of-Use pricing, enter your usage breakdown for each time period

The calculator will show your estimated total cost, including any applicable taxes and fees. Note that this is an estimate and your actual bill may vary based on your specific usage and any promotions or credits you receive.

Formula Used

The basic formula for calculating your Ontario Hydro bill is:

Total Bill = (On-Peak Usage × On-Peak Rate) + (Mid-Peak Usage × Mid-Peak Rate) + (Off-Peak Usage × Off-Peak Rate) + (Fixed Monthly Fee) + (Environmental Levy) + (HST)

For Time-of-Use plans, the calculation is similar but with separate rates for each time period. The calculator uses current Ontario Hydro rates as of [current date].

Worked Example

Let's calculate a sample bill for a Time-of-Use customer:

On-Peak Usage: 200 kWh at $0.15/kWh
Mid-Peak Usage: 300 kWh at $0.10/kWh
Off-Peak Usage: 500 kWh at $0.08/kWh
Fixed Monthly Fee: $12.00
Environmental Levy: $0.003/kWh
HST: 13%

The calculation would be:

(200 × $0.15) + (300 × $0.10) + (500 × $0.08) + $12.00 + (1000 × $0.003) × 1.13 = $30 + $30 + $40 + $12 + $3.30 × 1.13 = $115.39

So the estimated total bill would be $115.39.
