About CalcYards
CalcYards is a free collection of construction material calculators built for homeowners, contractors, and DIYers. Whether you are pouring a concrete slab, planning a gravel driveway, or mulching a garden bed, CalcYards gives you an instant, accurate answer, with no signup, no email, and no fluff.
What we calculate
CalcYards covers concrete bag counts for slabs, footings, and post holes; gravel volume and tonnage for driveways and landscaping; and mulch volume plus bag counts for garden beds, with all results shown instantly as you type.
How it works
The calculators run entirely in your browser. No data is sent to any server. Your dimensions are never stored or shared. The math is based on industry standard yields: 80 lb concrete bags at 0.60 cubic feet per bag, crushed stone gravel at 1.4 tons per cubic yard, and standard 2 or 3 cubic foot mulch bags.
Who built this
CalcYards was built as a focused utility: one site that does one thing well. The goal is to be the fastest, most accurate free calculator for construction materials online.
