Terms of Use

Results are estimates for planning, produced from the formula and assumptions stated on each page. They are not quotes, guarantees, or professional advice — financial, structural, electrical, or otherwise.

Verify critical figures (material quantities, electrical loads, money decisions) with a qualified professional or an official source before acting on them.

The site is free for personal and commercial planning use. Do not scrape it aggressively, misrepresent its outputs as certified calculations, or use it for anything unlawful.

Page content and design are provided as-is. Formulas shown are standard published methods; your inputs and results remain yours.

To the extent permitted by law, HowMuchTool is not liable for decisions made using its estimates. If any part of these terms is unenforceable, the remainder still applies.
