About BUILDMATH

BUILDMATH provides free browser-based calculators and planning insights for early real estate, construction cost, conversion, underwriting, area, parking, debt, and land-basis screening.

What BUILDMATH is

BUILDMATH is a planning-level decision-support website. The calculators are designed to make assumptions visible, compare early scenarios, and help users identify which questions deserve deeper professional review.

The tools are intentionally browser-based and fast. They are useful for early screening, but they are not a substitute for a licensed architect, engineer, contractor, cost estimator, attorney, accountant, appraiser, lender, broker, code consultant, or local authority review.

Important use limitations

Planning-level only

Outputs are early screening estimates based on user-entered assumptions and simplified logic.

Not a professional estimate

Outputs are not bids, quantity surveys, appraisals, legal opinions, code determinations, or permit approvals.

User assumptions matter

Incorrect, optimistic, incomplete, or outdated inputs will produce unreliable results.

Professional review required

Final decisions should be reviewed by qualified professionals and local authorities.
