Debris Dumpster
C&D volume from area and debris intensity; suggests roll-off size.
About this calculator
This calculator turns a project's floor area and demolition intensity into an estimated construction-and-demolition debris volume in cubic yards, then maps that volume to a suggested roll-off dumpster size. The Intensity selection -- Light, Medium, Heavy, or Gut -- moves the result more than the Area input does: stepping from Light to Gut roughly quadruples Debris (yd³) at any given area, since the engine multiplies area by a debris factor of 1 through 4 depending on the selection, while a proportional change to Area alone only ever changes the result by that same proportion. The dumpster size suggestion is a set of fixed breakpoints: a 20 yard roll-off up to about 12 cubic yards of debris, 30 yards beyond that, and 40 yards once the estimate passes about 22 cubic yards.
Area (ft²) should reflect the total floor space affected by the work -- not the footprint of a single wall or room -- and Intensity should describe how much of that space is being gutted versus lightly trimmed. This is a rough-order estimate: it does not weigh materials, separate recyclable debris, or account for disposal fees, which vary by hauler and by what's actually in the load.

How to Use This Calculator
- Enter the project floor area in square feet.
- Select the debris intensity: light (selective work), medium (standard renovation), heavy (full demo), or gut (strip to studs/structure).
- Read the estimated debris volume in cubic yards and the suggested dumpster roll-off size to order.
How the result changes with Area (ft²)
| Area (ft²) | Debris (yd³) |
|---|---|
| 1,200 | 0.4 |
| 1,800 | 0.7 |
| 3,600 | 1.3 |
| 6,000 | 2.2 |
What each input means
- Area (ft²)
- Total floor area of the project in square feet. Include all affected areas.
- Intensity
- Light = selective trim/cosmetic work. Medium = standard renovation. Heavy = full demo. Gut = strip to studs or structure.

Frequently Asked Questions
Why does the debris intensity selection matter more than the project area?
Intensity sets a multiplier from 1 (Light) to 4 (Gut) that scales the debris volume directly, so moving from Light to Gut work on the same floor area roughly quadruples the Debris (yd³) estimate. A proportional change to Area (ft²) alone only changes the result by that same proportion, which is a smaller swing across the intensity options offered.
What is the difference between Medium and Heavy debris intensity?
Medium intensity models a standard renovation where framing and structure largely stay in place, while Heavy intensity models a full demolition that removes most interior material. Selecting Heavy roughly doubles the estimated debris volume compared to Medium at the same project area.
How does the calculator decide which dumpster size to suggest?
It compares the estimated Debris (yd³) figure to two breakpoints: projects under about 12 cubic yards get a 20 yard roll-off suggestion, projects up to about 22 cubic yards get 30 yards, and anything beyond that gets 40 yards. These are rough sizing breakpoints, not a guarantee a hauler stocks that exact size locally.
Should I enter the total home area or just the room being renovated?
Enter the total floor area actually affected by the demolition or renovation work, not the full home if only part of it is being touched. Including untouched square footage will inflate the debris estimate and push the dumpster suggestion larger than the job actually needs.
