TheSiteMath

TheSiteMath is a collection of free online calculators for estimating construction materials and job costs. It addresses the need for quick material takeoffs in areas such as roofing, concrete, drywall, landscaping, fencing, and masonry without requiring software installation or user accounts.

Users select from a list of specialized calculators and enter dimensions to receive instant estimates. The roofing calculator determines shingles, squares, underlayment, and labor costs for any roof type. The concrete calculator computes cubic yards, bags, and total cost for slabs, footings, and driveways. Drywall and drywall mud calculators calculate sheets, joint compound, tape, screws, gallons, and bucket counts for walls, ceilings, taping, finishing, texture, and touch-ups. Other tools cover dirt and fill, mulch, topsoil, gravel, pavers, rafters, fencing, masonry, concrete blocks, flooring, tile, gutters, sod, and grass seed, each producing quantities such as cubic yards or required units along with associated costs where applicable.

The service is delivered entirely through a web browser. No signup is required, and all calculators are accessible directly from the site. It includes supporting sections for how-to guides and a blog in addition to the calculator tools.

TheSiteMath operates on a free model with no paid tiers or licensing restrictions mentioned.
