33 free calculators, built to give contractors and DIYers a fast, trustworthy material estimate.
Most "concrete calculators" online are either buried inside ad-heavy blog posts or too generic to trust for an actual jobsite order. ConcreteYard was built to fix that: 33 single-purpose calculators, each doing one job well — slabs, footings, walls, posts, rebar, mix ratios, cost — with the math shown plainly and no sign-up required.
Every calculator on this site uses the same standard assumptions (150 lb/cu ft normal-weight concrete, standard bag yields, common mix ratios) so figures stay consistent whether you're pricing a driveway or ordering bags for a fence post.
Contractors doing a fast takeoff, DIYers pouring their first patio, and estimators double-checking a supplier's quote. The tools don't replace an engineer's stamp on structural work — they're built to get you a reliable material estimate in under a minute.
Every calculation runs client-side in your browser — nothing you enter is sent anywhere. The site is static (no tracking scripts beyond basic analytics), fast, and works the same on a jobsite phone as it does on a desktop.
These tools give material estimates using standard industry rules of thumb. For structural work, permitted projects, or anything load-bearing, always confirm quantities and specifications with a licensed contractor or engineer.
