Get material quantities, labor estimates, and project cost breakdowns — not just a single number.
Slabs, footings, columns, and stairs — cubic yards, bags, and cost.
Calculate →Shingles, underlayment, and tear-off costs by roof size and pitch.
Calculate →Sheets, joint compound, tape, and screws for any room.
Calculate →Posts, rails, pickets, concrete, and cost from your linear footage.
Calculate →Gallons, primer, and supplies by room size and finish type.
Calculate →Boxes, underlayment, transitions, and cost for any material.
Calculate →Every BuildCrunch calculator is built on the same math contractors use in the field: standard material coverage rates, industry waste factors, and current price ranges for materials and labor.
We start with your project dimensions, apply the correct formulas for each trade — square footage, cubic yards, linear feet, roof pitch multipliers — then add a realistic waste factor so you don’t come up short mid-project. Material prices reflect typical big-box and supplier pricing, and installed costs are based on common contractor labor rates.
Every calculator shows its work. Scroll to the “How It’s Calculated” section on any tool to see the exact formula behind your estimate. Prices vary by region and job conditions, so treat these as planning numbers — and when you’re ready for an exact price, request quotes from local pros right from your results.
BuildCrunch gives you real construction estimates, not ballpark guesses. Every calculator breaks your project down the way a contractor would: exact material quantities, waste factors, itemized supply lists, and cost ranges based on current pricing — so you know what you’re buying and why before you set foot in the store or sign a quote.
Whether you’re pouring a concrete slab, replacing a roof, hanging drywall, building a fence, painting a room, or laying new flooring, you’ll get the numbers that matter: how much material to buy, what it should cost, and what to expect if you hire it out.
Built for homeowners planning a project, DIYers making a materials run, and contractors who want a fast sanity check before writing an estimate. No signup required, no spam — just answers.
Not sure whether to DIY or hire a pro? Each calculator includes installation cost guidance and a frequently asked questions section covering the details that trip people up — permits, waste factors, material grades, and how long each material actually lasts. Crunch the numbers before you build.
