Demolition Debris Calculator

Estimate debris after a tear-out

Measure the loose pile, multiply length × width × average height, and divide by 27 for cubic yards. For example, a pile 9 feet long, 6 feet wide and 3 feet high is about 6 cubic yards.

Breaking apart walls, cabinets and flooring changes how materials stack. Room dimensions describe the space inside a room, not the amount of debris it will produce. If demolition has not started, describe the materials and scope to our team rather than entering the building dimensions here.

Keep your measurement units consistent

With feet selected, enter 3.5 for three feet six inches. With inches selected, enter 42 for that same measurement. Do not enter feet for the length and inches for the height. For an inches-only calculation, multiply the three measurements and divide by 46,656 to get cubic yards.

Separate heavy materials from bulky debris

Drywall, lumber and cabinetry take up space differently from concrete, tile and brick. This volume estimate does not establish an allowable weight. Let us know about heavy material before choosing a container or combining waste streams.

For concrete slabs, use the concrete calculator. For shingles, use the roofing estimator. For mixed tear-outs, review demolition dumpster service and request help with size and loading limits.

Planning more than one pile

Calculate each pile separately and add the cubic-yard estimates. Keep a note of the material in each pile. Share both the volume and materials when requesting a quote; the calculator does not reserve a container or authorize a load.
