About KiloBill

KiloBill is a free tool that helps you understand your electric bill, check whether your rate is normal for your state, and find the changes that will save you the most money.

Why we built it

Most people open their electric bill, see a number that feels too high, and have no way to tell why. Is the rate unusual? Is something in the house using too much power? Is there help available? Answering those questions usually means digging through utility websites, government tables and energy-saving lists that don’t say how much each tip is actually worth.

KiloBill does that work for you. With two numbers from your bill, the total amount and the kWh used, it compares your price with your state’s average, estimates where your money goes, and builds a savings plan in real dollars, sorted by what saves the most.

Where our numbers come from

• State average prices come from the U.S. Energy Information Administration (EIA), Electric Power Monthly, residential sector. We currently use the average for January–July 2026, which includes all fees and charges, and we update it as new data is published.
• Typical household usage and bills by state come from the EIA’s yearly survey of electric utilities (form EIA-861), 2024 data.
• Appliance estimates and savings tips are based on typical U.S. homes and on guidance from the U.S. Department of Energy and ENERGY STAR. Your home will differ, so treat the results as a starting point, not a quote.

What KiloBill is not

We are not a utility, an electricity supplier or a government agency, and we don’t sell electricity plans. The site is free because it shows advertising and, on some pages, affiliate links: if you buy a product or sign up for a service through one of them, we may earn a commission at no extra cost to you. Affiliate links are always labeled, and partners never decide what we recommend. Your savings plan is sorted only by how much each change saves you.

KiloBill does not give financial or legal advice. If you think your bill is wrong, contact your utility first, and if that doesn’t resolve it, your state’s public utility commission.
