Terms of Use

By using WattSpend, you agree to these terms. WattSpend provides free cost calculators and guides for general information only.

Estimates, not advice

Every figure on WattSpend is an estimate based on public data and editable assumptions. Electricity rates, fuel prices, equipment costs, and incentives vary by location and change over time. Nothing on WattSpend is financial, tax, or electrical advice. For a real project, verify with your utility bill and get quotes from licensed professionals.

No warranty

WattSpend is provided “as is,” without warranties of any kind. We work to keep data accurate and dated, but we do not guarantee that any figure is current or correct for your situation.

Affiliate and advertising

WattSpend earns revenue from display ads and affiliate links (which are marked). Affiliate relationships never change the price you pay and do not influence our formulas or methodology.

Changes

We may update these terms as the site evolves. Continued use after an update means you accept the revised terms.
