What Size Dumpster Do I Need Calculator
Most home cleanouts fit in a 20-yard dumpster — about 6 pickup truck loads — pick your project and this calculator recommends what size dumpster you need, with a second mode that estimates the rental cost.
7-day base rates: 10 yd $300–$500 · 20 yd $400–$600 · 30 yd $500–$750 · 40 yd $600–$900.
When in doubt, size up — a second haul costs far more than the step up to the next size.
Estimates only. Figures are planning ballparks based on national averages — actual prices vary by region, contractor, and project details. Get 2–3 local quotes before budgeting.
How the dumpster size calculator works
Dumpster sizes are named in cubic yards: a 20-yard dumpster holds 20 cubic yards of debris. The project picker maps common jobs to the size contractors actually order; the truck-load input converts directly at about 3.3 cubic yards per pickup load.
Rental cost is a 7-day base rate plus a daily fee for extra days, scaled by region. Weight overages are the hidden gotcha — heavy materials like shingles, concrete, and dirt hit the tonnage cap before the dumpster looks full.
yards ≈ truck loads × 3.3 · cost = base + extra days × $12.50, × region
