An independent calculator, not a solar company
killmyenergybill.com is an independent decision tool for US homeowners: it works out whether solar pays for itself on your specific roof, using your state’s electricity rate, your sun hours, your usage and current installed costs — and it tells a lot of people no.
It is not an installer, not a utility, not a marketplace, and not a lead broker. There is no network of companies waiting behind a form. The whole product is the arithmetic, and the arithmetic appears before anyone asks for a phone number.
Who it is for
Homeowners who have been quoted, or are about to be, and want to check the numbers themselves before a salesperson sits at their kitchen table. Also the people who have been told solar is obviously worth it and suspect that depends on where they live and what they pay per kilowatt-hour. It does.
It is also for anyone who wants the underlying data. The state model is published in full at /data, with a JSON download, and the formulas are at /methodology. Journalists and researchers are welcome to both — attribution is the only condition.
The independence stance
Nobody here earns more when a system gets bigger, and nobody earns anything when the answer is yes rather than no. That is the entire reason this site can print things a lead-generation site cannot afford to print: that the federal homeowner credit is gone, that most states no longer pay retail for exported power, and that on plenty of roofs the honest answer is keep your money.
No manufacturer, installer or financier pays for placement here, and none is ranked, rated or recommended in exchange for anything. If that ever changes it will be disclosed on the page it affects, not in a footer.
How it makes money
The calculator is free. If, after seeing the results, you decide you want to talk to someone, we can introduce you to a single installer whom you see by name and approve first, and we may be paid for that introduction.
That is the whole model, and it is written out in more detail — including what we are paid for and what we are not — on the how-we-make-money page. Read it before you trust anything else here.
What this site will not do
- Sell your details into a lead pool. Nothing leaves this site until you see a named company and say yes to that one company.
- Quote a federal homeowner tax credit. The 30% credit under IRC Sec. 25D ended for systems placed in service after December 31, 2025, and pretending otherwise would make every net cost on this site wrong.
- Publish a statistic we cannot source. Where a figure does not exist, the point gets made qualitatively instead of invented.
- Claim a review board, an accreditation, a partner network or a press mention we do not have.
- Tell everyone yes. Renters, homes with heavy shade, roofs over twenty years old and bills under $100 a month get told no, with the reason.
- Push a battery, a monitoring subscription or a roof upgrade as an add-on. We do not sell anything to install.
Who is behind it
A small, new operation. There is no newsroom here, no advisory board, no team page with headshots, and no third-party reviewer signing off on the numbers — so none of those is claimed anywhere on the site, including in the structured data.
What there is instead: a model whose every constant is published, sources that are public and named, review dates that are per-state rather than one frozen stamp, and a standing invitation to tell us a number is wrong. That is a weaker credential than a masthead and a more checkable one.
Nothing on this site is financial, tax or legal advice. It is arithmetic on public data. Any real price still comes from an installer who has been on your roof, and any tax question belongs with someone qualified to answer it.
Corrections
If a rate, incentive or net metering rule here is out of date or wrong, we want to know, and the fix goes in rather than being argued about. State inputs are reviewed on a rolling basis; the site-wide data refresh is dated 2026-08-01, and each state page carries its own review date.
