How to use it

  1. Enter the square‑footage of the space you plan to demolish.
  2. Input the demolition cost per square foot (typical $5‑$15).
  3. Add the cubic yards of waste and the disposal cost per cubic yard (typical $30‑$50).
  4. Read the total demolition cost shown at the bottom.

What it does – The calculator adds two line items: demolition labor/materials based on square footage and disposal fees based on volume. Why it matters – Knowing the total cost before you bid helps you set realistic budgets, compare contractors, and avoid surprise overruns. How to read it – The result is a single dollar amount that combines area × demolition $ per ft² plus volume × disposal $ per yd³. No hidden fees, just a clear picture of what the job will cost you today.

Pro tips

  • Add a 10% waste allowance to the volume to cover unexpected debris.
  • Round square footage up to the nearest 10 ft² for a safer estimate.
  • Get multiple disposal quotes; prices often vary between $30 and $50 per yd³.
  • Double‑check that you’re using interior demolition rates ($5‑$15) not specialty rates.

Real-life examples

  • A homeowner planning a kitchen remodel needs to know demolition expenses before hiring a contractor.
  • A property manager estimating costs to clear out a vacant office building.
  • A small contractor preparing a bid for a retail storefront demolition.

Case study

Sara, a boutique owner, entered 1,200 ft² at $12/ft² and 150 yd³ at $38/yd³. The estimator showed $19,800 total, letting her negotiate a contractor price that stayed under budget.

Frequently asked questions

How do I know which demolition cost per square foot to use?
Use the interior range $5‑$15 per ft²; choose a value that matches the finish level and complexity.
What if my waste volume is unknown?
Measure the space, estimate depth of material, then convert to cubic yards (1 yd³ = 27 ft³).
Are disposal fees included in the demolition cost?
No, disposal is separate; the calculator adds both to give the total.
Can I use this calculator for exterior demolition?
The tool is calibrated for interior work; exterior projects often have higher rates.
Do I need to add taxes or permits?
Those are extra; the estimator provides only demolition and disposal totals.
