Use our bill calculators to help you:

Compare electricity price plans

Residential and small business customers can choose their electricity price plan. Find out more.

Power is personal. Depending on how much electricity you use and when you use it, one price plan may suit you better than the others. Use our calculator to see what your total bill would look like under Time-of-Use (TOU), Ultra-Low Overnight (ULO) and Tiered prices, taking into account the other rates charged by your electricity utility (Delivery and Regulatory) and the Ontario Electricity Rebate.

To switch between price plans, you must notify your utility by completing an election form. You can get the election form on your utility’s website or by contacting them.


  • Get your utility bill, or several months of bills. To use the calculator most effectively, you’ll want to know how much electricity you use and when you use it. You can find this information on the Electricity line of your bills, your utility may provide your data when you access your account online, or contact your utility for more detailed information about your electricity use.
  • Remember, your monthly use and usage pattern may be different in the winter season than it is in the summer season.

See how your bill might look on an energy contract

Compare your current bill from your local utility with what to expect if you sign an energy contract with an energy retailer (also called an electricity retailer or a natural gas marketer). The bill calculator uses the regulated rates for each utility in Ontario. You can enter the contract price offered by the energy retailer to compare.
