Rate Plan Quick Comparison Tool
A simple way to compare TOU, Tiered, and ULO electricity rates using your monthly kWh usage.
Updated 2026‑04‑22
What This Tool Does
This tool provides a quick, side‑by‑side comparison of how much you would pay under different electricity pricing plans using average rates that you enter manually. It is designed for households who want a fast, approximate comparison without needing detailed hourly usage data.
It is not a bill calculator and does not include delivery charges, regulatory charges, or the Ontario Electricity Rebate. It simply shows how the energy portion of your bill changes under different pricing structures.
For a full bill estimate, use the Ontario Electricity Bill Calculator.
How to Use the Tool
Enter:
- Your monthly kWh usage (from your bill or smart meter portal)
- Your estimated average TOU rate
- Your estimated average Tiered rate
- Your estimated average ULO rate
Then click Compare. The tool will show the energy‑only cost for each plan.
Average rates are useful when:
- you know your typical usage pattern
- you want a quick comparison without detailed modelling
- you are deciding whether to switch plans

Educational only. Actual bills depend on your utility’s delivery structure and current OEB‑regulated rates.
How to Interpret the Results
The output shows the energy cost only for each plan. This helps you understand:
- which plan is cheapest based on your usage pattern
- how sensitive your bill is to rate changes
- whether switching plans might be worthwhile
Remember:
- Delivery charges do not change when you switch plans.
- The Global Adjustment is already built into regulated rates.
- Seasonal usage changes can affect which plan is best.

Why Average Rates Matter
Average rates are a simple way to compare plans without needing hourly data. They are especially useful when:
- your usage pattern is consistent month to month
- you want a quick estimate before switching plans
- you are comparing EV charging scenarios
- you want to understand the impact of off‑peak usage
They are not perfect, but they provide a fast, practical starting point.
