Who Publishes This Site

Content on theconcretecalculator.com is researched, written, and maintained by The Concrete Calculator Team, a small editorial group focused on practical concrete-estimating tools rather than a single named author. We use a team byline instead of an individual name because the calculators and reference charts are the product of ongoing review and correction, not a one-time write-up by one person.

Our Editorial Process

Formulas and figures on this site are checked against published standards including ACI 318, ASTM A615, and the International Residential Code (IRC) before publication. Where a page cites a specific table or clause, such as IRC Table R403.1(1) for footing sizing or ASTM A615 for rebar weight, we name the source directly instead of paraphrasing an unverified number from elsewhere.

• Every calculator’s formula is documented in plain language directly on its page, so you can verify the math yourself.
• Reference data such as rebar weights and footing minimums is sourced from ASTM, ACI, and IRC publications, not estimated.
• Pages are periodically reviewed and re-dated when standards references or figures are updated.
• We do not accept paid placement that would change a formula, a default value, or a recommendation.

What This Site Is Not

These calculators are planning and estimating tools, not a substitute for a licensed structural engineer, geotechnical report, or your local building department. Actual footing depth, reinforcement, and mix design for a specific project depend on soil conditions, local code amendments, and load requirements that a calculator cannot see. Always confirm project-specific requirements with a licensed professional before construction.

Questions or Corrections

If you find a figure that looks incorrect or out of date, or a source we should be citing more precisely, please get in touch so it can be reviewed and corrected.
