GravelCalc - Fill Calculator

GravelCalc is a fast, precise volume and weight calculator for landscaping and fill materials. Built for contractors, landscapers, and DIYers who need to know exactly how much material to order — and how much it weighs. SIX MATERIALS, ACCURATE DENSITIES Calculate volume and weight for gravel, mulch, topsoil, sand, decomposed granite, and river rock. Each material has its own density data, so weight estimates are accurate whether your supplier charges by the cubic yard or by the ton. FOUR AREA SHAPES - Rectangle — driveways, paths, garden beds, patios - Circle — tree rings, fire pit surrounds, round patios - Triangle — corner beds and angled areas - L-Shape — paths and beds that wrap around corners INSTANT RESULTS Enter your dimensions and depth, and instantly see: • Volume in cubic yards and cubic metres • Weight in tons and tonnes (based on material density) • Number of dump truck loads needed • Cost estimate (set your own price per yard and delivery fee) PROJECT TRACKER Combine multiple calculations into one project. Mix materials — gravel for the driveway, mulch for the beds, topsoil for the lawn — and see combined volume, weight, truck loads, and cost. Share a plain-text summary with your supplier or client. BUILT FOR THE FIELD • Works 100% offline — no internet needed • Imperial and metric units • Waste factor adjustment (0–15% or custom) • Quick-select depth presets for common depths • Customisable truck capacity • Reference tables for densities, recommended depths, coverage, and truck sizes PRIVACY FIRST No account required.
