Who Built This?
AceCalc is built and maintained by Daniel McCarney. The calculators started as a personal tool for estimating materials on real projects — and grew into a free resource for anyone who needs accurate numbers before placing an order. Every calculator on this site uses the same formulas and density tables that material suppliers, ready-mix plants, and estimating software rely on — sourced from ACI standards, manufacturer technical data sheets, and industry reference guides.
The goal is simple: give contractors and homeowners a fast, free way to estimate materials without signing up, downloading an app, or wading through ads. Enter your dimensions, get your answer.
Why Trust These Calculators?
Every formula on AceCalc is grounded in published industry data. Concrete densities follow ACI 318 and Portland Cement Association guidelines. Aggregate weights match ASTM C33 gradation standards. Rebar specifications reference ACI rebar size and lap-splice tables. Asphalt densities come from the Asphalt Institute.
Where a calculator uses a default value — like 0.6 cubic feet per 80-pound bag of concrete — that number comes directly from the manufacturer's published yield data (Quikrete, Sakrete). If you spot an error or your local supplier uses a different spec, let me know and I'll fix it.
What AceCalc Covers
AceCalc currently offers 12 free calculators covering the most common construction materials: concrete, gravel, mulch, sand, topsoil, pavers, rebar, brick, asphalt, fill dirt, drainage rock, and retaining wall blocks. New calculators are added regularly — French drain, fence post, deck board, and drywall are next.
Each calculator page includes worked examples, depth guides, cost estimates, and FAQ sections targeting the specific questions contractors and homeowners ask most often.
