How we publish
A smaller directory you can trust
We only list tools whose core assumptions have been reviewed. Calculators that need refreshed rates or clearer methodology stay out of this directory until they are ready.
Review calculators and sourcesPrimary sources
Tariffs, ratebooks, agency guidance, and official program terms anchor the models.
Review dates
Each card and calculator shows when its supporting assumptions were last checked.
Visible limits
Worked examples and caveats explain what the estimate includes—and what it does not.
Not sure which tool to use?
Start with your utility bill calculator, then use the project-specific tool to test the change you are considering.
