Terms of Use
Last updated 19 August 2026
By using https://kilowattcost.com you agree to these terms. If you do not agree, please do not use the site.
Use of the site
KilowattCost is provided free for personal and commercial reference. You may use our calculators and cite our results, provided you attribute them with a link.
You agree not to: attempt to disrupt or overload the site; scrape it at a volume that degrades service for others; republish substantial portions of our content as your own; or use the site for any unlawful purpose.
Accuracy and no warranty
We work hard to be accurate, and our formulas are automatically tested. Even so, results are estimates. They depend on assumptions, published averages and figures you supply, all of which vary in the real world.
The site is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant the site will be uninterrupted or error-free.
Not professional advice
Nothing here is financial, engineering, legal or tax advice. See our disclaimer. Before committing to a significant purchase — solar, a heat pump, a vehicle — consult a qualified professional and obtain site-specific quotes.
Limitation of liability
To the fullest extent permitted by law, KilowattCost and its operators shall not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, revenue or savings, arising from your use of, or reliance on, this site.
Third-party links
We link to third-party sites for reference or as partners. We do not control them and are not responsible for their content, products or privacy practices.
Intellectual property
Site content, design and code are owned by KilowattCost unless stated otherwise. Underlying physical formulas are not proprietary, and we publish them openly on our methodology page.
Changes
We may revise these terms. Continued use after changes constitutes acceptance.
