About HomeCalc — Building Material Calculators

HomeCalc is a collection of online calculators for building material estimating. No sign-up, all math runs in your browser.

Help

HomeCalc started with a simple frustration: every time we planned a small project — spreading mulch, pouring a patio, painting a room — we'd end up on a dozen different websites, each with its own clunky calculator, pop-ups, and "sign up to save" nonsense. We thought we could do better.

So we built a single place where you can estimate just about any building material. All calculations run in your browser — no sign-up, no accounts, instant answers.

What you can calculate

  • Landscaping: mulch, gravel, topsoil, sand, sod and pavers for yards and garden beds.
  • Concrete: slabs, pads, footings, blocks, brick, mortar and rebar for foundations and hardscapes.
  • Paint & wall: paint, spray coverage, wallpaper and drywall for room makeovers.
  • Flooring: tile, hardwood, carpet, stair treads and baseboard for renovations.
  • Deck & fence: deck boards, fencing, lumber, rafters and stain for backyard projects.
  • Roofing: shingles, roof pitch, underlayment and gutters before you replace a roof.

Who it's for

Weekend DIYers planning their first flower bed, homeowners sizing a fence or a paint job, and pros who just need a quick sanity check before ordering. The estimates are built on standard material densities, so they're great for planning and budgeting — just remember to add a little extra for waste.
