Demolition Debris Calculator
Multiply the debris pile's length, width, and average depth for cubic feet, convert to cubic yards, apply your weight-per-cubic-yard estimate for pounds and tons, and suggest the smallest standard dumpster that holds the volume.

Method and assumptions
Figur turns your measurements into purchase quantities with standard geometry: it computes the area, length, or volume, applies the waste or spacing you enter, and rounds up to whole purchase units. Everything is calculated locally in your browser.
- Purchase quantities round up to whole units (sheets, bundles, boards, bars, or packages) because suppliers do not sell fractions.
- Assumed coverages and package sizes (for example, 3 bundles per square or 4×8 sheets) are common conventions; verify your product label and supplier.
- The waste percentage is applied exactly as entered; complex cuts, patterns, and damage can require more.
- The result does not replace your field measurements, plans, or local code requirements.
This tool provides a planning takeoff, not a binding bid, structural design, or engineering advice. Confirm quantities with field measurements, your supplier, and the applicable professionals before buying.

No external data source is required: this calculator applies standard geometry to the measurements, coverages, and waste you enter.
Frequently asked questions
What weight per cubic yard should I use?
Mixed light construction debris often runs 300–400 lb per cubic yard, while concrete and masonry can exceed 2,000 lb. Weight drives disposal fees, so match the number to what you are tearing out.
Can I rely on the dumpster suggestion?
Use it as a starting size only. Haulers enforce their own weight limits and fill lines, and heavy material can max out a container's weight long before its volume.
