Terms of Service

Use the site as a practical estimating and reference tool, but do not confuse it with final approval, stamped design, or code authority.

How The Site Should Be Used

CalcTrades is meant for planning, estimating, and reference use. It can help you move faster on takeoffs, rough calculations, and common trade math, but it is not a substitute for project documents, inspection requirements, manufacturer instructions, or licensed professional review.

No Professional Relationship

Using this site does not create an engineer-client, contractor-client, consulting, or professional advisory relationship of any kind. The calculators and reference pages are informational tools made available to the public, not project-specific recommendations for your job.

No Guarantee Of Fit For Every Job

Job conditions change. Local code changes. Material specs change. Site constraints change. Because of that, the site is provided as-is without any promise that every page, formula, or reference will fit every jurisdiction, installation, or use case.

Content Can Change

Calculators, formulas, assumptions, layouts, related links, and reference content may be updated, expanded, corrected, or removed over time without notice. The site is an evolving resource, and it is the user’s responsibility to confirm that a result still matches the current page, current standard, and current project conditions.

Acceptable Use

You may use the site for lawful personal, business, or project-planning purposes. You may not use the site in a way that interferes with performance, attempts to break functionality, misrepresents ownership, or republishes site content in a deceptive or unauthorized way.

External Standards Still Control

Where there is any conflict between a site output and a governing code, published product specification, project drawing, or instruction from an authority having jurisdiction, the outside authority controls. The site is a convenience tool, not the controlling source.

Your Responsibility

If a result affects cost, compliance, safety, purchasing, installation, structural performance, or permit approval, verify it before relying on it. The site can help with the math, but the final responsibility for using that information stays with the person doing the work or approving the work.
