Which expenses are fixed and which move with sales in a dumpster rental break-even model?

Cost classification

Break-even works only if overhead stays separate from haul-driven spend. Fixed monthly overhead totals $10,400 before payroll, while disposal, fuel, marketing, and maintenance should move with rental volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Industrial Yard and Office Rent	Fixed	Use $5,500 per month as overhead in the relevant planning range.	Don’t tie yard rent to bookings.
Commercial Truck Insurance	Fixed	Use $2,200 per month as recurring overhead.	Don’t treat policy premiums as per-haul spend.
Dispatch and Logistics Software	Fixed	Use $450 per month as a fixed operating tool.	Don’t bury dispatch software in marketing.
Disposal and Landfill Tipping Fees	Variable	Model at 12.0% of first-year revenue, then apply the forecast rate by year.	Don’t classify landfill fees as overhead.
Fleet Fuel and Oil	Variable	Model at 5.0% of first-year revenue because route miles rise with jobs.	Don’t smooth fuel into fixed truck expense.
Digital Marketing and Lead Generation	Variable	Model at 2.0% of first-year revenue since bookings drive spend.	Don’t hold paid lead spend flat as volume grows.
Fleet Maintenance and Wear Parts	Semi-variable	Model at 0.5% of first-year revenue, with usage and fleet age both affecting spend.	Don’t ignore wear from higher rental turns.
CDL Driver Salaries	Semi-fixed	Model payroll in staffing steps, rising from 2 drivers in Year 1 to 6 drivers by Year 5.	Don’t model every driver dollar as per rental.

How does break-even change from lean to full utilization in a roll-off dumpster service?

Scenario table

Break-even moves with container turns, haul distance, landfill tipping fees, and driver capacity. Lean months sit close to the line, base months add cushion, and full months give the widest buffer if routes stay tight.

Planning assumptions only; actual results will vary with route density, landfill fees, and haul distance.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean: Year 1 average month	$53K	$14K	$32K	74%	$7K	Near the line; small margin for error.
Base: Year 2 average month	$78K	$21K	$42K	73%	$15K	Break-even is covered, but labor load is higher.
Full: Year 3 average month	$116K	$30K	$49K	74%	$38K	Strong cushion if turns and routes stay efficient.

What breaks the break-even plan for this dumpster business?

Stress test

The base plan clears break-even, but the cushion shrinks fast if bookings soften or landfill, fuel, or insurance costs rise. A 10% revenue dip still works; a 20% dip or 10% higher overhead makes the buffer tight.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in bookings, costs, or overhead.	$398K	$132K cushion	The buffer is solid, but not wide.
Revenue shortfall	Monthly revenue falls 20% to about $424K.	$398K	$26K cushion	One weak month away from a tight finish.
Fixed-cost increase	Fixed overhead rises 10% to about $353K a month.	$439K	$91K cushion	Higher rent, insurance, or admin spend cuts the spread.
Margin pressure	Variable costs rise 5 points, lowering contribution margin to 75.5%.	$425K	$105K cushion	Higher tipping, fuel, or wear parts push break-even up.
Combined pressure	Revenue falls 10%, variable costs rise 5 points, and fixed overhead rises 10%.	$470K	$7K cushion	Almost no room for slower jobs or extra haul cost.

Is this roll-off dumpster business ready to lock in the yard, trucks, and drivers?

Founder checklist

Before you sign anything, prove the model can reach the $398K monthly break-even revenue and still keep the Month 6 cash floor intact. If demand, disposal costs, and route density don’t hold together, wait on the major spend.

1Demand Proof$398K/mo

Verify booked work or firm pipeline can reach the modeled break-even revenue before you commit to trucks, rent, and payroll.

2Contribution Margin74% CM

Verify the route mix can hold about a 74% contribution margin after disposal, fuel, and lead-gen spend, or the Month 2 break-even date will slip.

3Disposal Terms120% Y1 rev

Verify the landfill tipping agreement now, because the model shows disposal fees at 120% of Year 1 revenue and that kind of drag can wipe out the route math.

4Fixed Load$10.4K/mo

Verify the yard lease, insurance, software, utilities, and admin stack can stay near $10.4K a month, so overhead does not outrun early bookings.

5Capacity Ramp2 trucks

Verify CDL hiring, dispatch, and container inventory can handle the second truck in Month 6 before you scale marketing or open new routes.

6Cash Floor$440K

Verify cash can absorb the $185K truck in Month 1 and the $185K truck in Month 6, because the model still needs $440K minimum cash at the trough.
