Tariff Fit Checker
Use this tariff fit checker when you want to answer the earlier question before comparing retailer plans: is my home behavior more naturally suited to flat rate or time-of-use? It is meant to be a direction tool first, not a complete bill simulator.
Planning
First-party
Check whether flat rate or time-of-use is more likely to fit your home load pattern.
What this tool is for
Who this tool is for
Homes trying to decide whether flat rate or time-of-use is a better behavioral fit before diving into retailer-specific offers.
What this tool now makes clearer
It still works as a lightweight direction tool, but it now makes it easier to see which behavior is driving the answer most strongly, such as heavy evening imports, repeatable overnight EV charging, or battery support.
How to use the output
Use the result to identify the main behavior driver, then validate that pattern against interval data or a fuller bill comparison before you switch retailer plans.
Why this tool is worth using
- Helps users understand whether flat rate or TOU is a more natural fit before comparing retailer plans.
- Now makes the result easier to interpret by surfacing the main behavior driver behind the answer.
- Encourages smarter tariff thinking without pretending to replace a full bill simulation.
How to use it well
Think about controllable load timing
The key question is not whether TOU sounds cheaper. It is whether the home really has enough flexible load timing to make that tariff structure work week after week.
Use interval data if you have it
The result becomes much stronger when checked against a smart-meter or interval-data view instead of memory alone. If you already have that data, treat this tool as the first screen before a more detailed comparison.
Examples
Example
A home with heavy evening imports but no repeatable overnight EV charging often leans flat rate, while a home with disciplined overnight EV charging and battery support may look much more TOU-friendly.
What this tool does not replace
What this tool does not replace
It does not replace retailer-by-retailer bill modeling, controlled-load analysis, or demand-charge calculations. Use it to understand tariff direction first, then compare the full tariff structure.
How to continue
Open the tool when you know the question you are trying to answer
Use the interactive version once you know what inputs matter and what kind of answer you are expecting from it.
Use the result as guidance, not a final purchase promise
These pages are designed to make the tool easier to use correctly, but you should still validate important hardware, tariff, and compatibility decisions before buying.
