Each $425 rental nets $270 after the landfill and the driver — 8 cans at 4 turns is $8,240/mo, and cans in the yard earn nothing.
The dumpster business is a turns game: a can earns only while it sits on someone else's driveway. Each $425 ten-day rental of a 20-yard can nets $270 after the tipping fee and the driver — eight cans turning four times a month is $8,240 monthly net. The margin killers are weight overages absorbed instead of charged and swap-outs delivered Thursday that the customer needed Tuesday. This calculator prices the turn, the fleet, and the utilization honestly.
Roll-off operators use it to run the turns game: each $425 rental nets $270 after tipping and the driver — 8 cans at 4 turns is $8,240/mo, and yard-sitters earn nothing.
The unit economics are solid — $250–300 net per turn on a 20-yard can — and the business case is utilization: a $5,000 can turning 4×/mo pays for itself in under two years and lasts ten. What separates profitable operators: turns (the can in your yard earns nothing — same-day swap-outs and short rental periods force utilization; 7–10 day standards with $10–20/day overage fees that actually get charged, because the overage fee is both revenue and the nudge that returns your can), weight discipline (tipping runs $60–120/ton, so 2 tons included with $60–75/ton beyond protects you from the roofing-tearoff surprise — publish it in the contract or eat the shingles), and the contractor book (remodelers and roofers are the annuity — recurring monthly turns, price-insensitive to $25 — while homeowners are the marketing). The capital shape: cans are cheap ($4,500–6,500 new, half that used); the roll-off truck ($80–150k) is the real decision, and its turns-per-day capacity caps the whole fleet — a second truck doubles the business, a third can doesn't.
Flat rate by can size and rental period, with the weight limit printed in the same sentence: 10-yard $300–375, 20-yard $400–475, 30-yard $475–575, 40-yard $550–650 (regional variation is wide — landfill proximity drives tipping fees, which drive everything). The price includes: delivery, the rental period, pickup, and disposal up to the weight cap. What rides on top: weight overage ($60–75/ton beyond included tonnage — photographed scale tickets settle disputes), daily overage past the rental period ($10–20/day), trip fees for blocked or overloaded pickups ($75–125 — the can that can't be loaded costs a turn), and prohibited-item contamination (tires, batteries, chemicals, refrigerant appliances — the load rejected at the station is YOUR re-trip and YOUR cost; the contract lists them and the driver photographs every pickup). Market positioning: price at market, win on service — same-day delivery and answering the phone are the differentiators in a commodity market; the cheapest operator attracts the customers who dispute every charge.
The honest capital stack: a used roll-off truck ($50–90k used, $80–150k new), 5–8 cans to start ($25–40k mixed new/used), insurance (commercial auto + general liability, $8–15k/yr — the truck is heavy and the loads are heavy), yard space (zoned for it — neighbors complain about can storage), and DOT compliance (CDL drivers, DOT number, drug consortium). Total realistic entry: $90–150k. The startup sequence that works: buy the truck and 5 cans, work contractor relationships BEFORE the yard fills (roofers and remodelers commit to recurring turns; homeowners find you by search), and reinvest into cans — the fleet grows from cash flow once turns exceed 3/can. The margins live in operations: route-dense dispatching (fuel and driver hours are per-turn costs — clustered deliveries cut both), driver skill (a scratched driveway is a claim; a skilled placement is a review), and can maintenance (paint and repair keep the fleet rentable-looking — the can on the driveway is your billboard). Seasonality: construction peaks spring through fall; the contractor base and roofer relationships smooth winter. The exit is real: fleets with contracted commercial accounts sell at 3–4× annual earnings.
