About DisposalAssist
Free calculators that actually explain their math.
Why We Built This
We got tired of dumpster calculators that felt more like lead generation forms than actual tools. Most give you a number without explaining how they got there. Some use outdated formulas. Others are so complicated that you give up halfway through.
What Makes Us Different
Transparent Methodology
Every calculator explains how it works. We show you the formulas, not just the results.
Cited Sources
Our formulas come from EPA guidelines, industry associations, and engineering standards—not guesswork.
Actually Free
No signup walls. No email harvesting. No "call for a quote" dead ends. Just tools that work.
Simple by Design
We ask only what's needed. Get an estimate in seconds, not minutes.
Our Commitment
We believe that helping someone make an informed decision is more valuable than pushing them toward the most expensive option. Our calculators are designed to give you realistic estimates—with built-in safety margins—so you can plan your project with confidence.
