Which arborist service expenses stay fixed, and which move with booked jobs?

Cost classification

Break-even gets reliable only when each expense follows its real driver. Treat dump fees, fuel, and project insurance as job-linked, not overhead, or the model will overstate margin as sales grow.

Expense	Cost	Break-Even Treatment	Common Mistake
Office and Yard Rent	Fixed	Include $2,500 per month in fixed overhead for the relevant planning range.	Tying rent to job count instead of capacity.
Utilities	Semi-variable	Start with the $400 monthly amount, then watch usage as crew activity rises.	Assuming every dollar stays fixed at higher volume.
Business Insurance (Fixed Portion)	Fixed	Include $800 per month as fixed overhead before job-level insurance.	Blending fixed policy premiums with project-specific coverage.
Project-Specific Insurance	Variable	Apply the job-linked percentage to revenue: 7.5% in the first year, falling to 6.0% by Year 5.	Treating project insurance as overhead when it rises with booked jobs.
Fuel & Equipment Consumables	Variable	Apply as a revenue-linked expense: 9.5% in the first year, falling to 8.0% by Year 5.	Calling fuel fixed and overstating contribution margin.
Waste Disposal Fees	Variable	Model as job-linked disposal expense: 7.0% in the first year, falling to 6.0% by Year 5.	Putting dump fees in overhead instead of each job.
Subcontractor Fees	Variable	Apply to booked work: 5.0% in the first year, falling to 4.0% by Year 5.	Forgetting subcontractor use when demand exceeds crew capacity.
Marketing	Semi-fixed	Use the annual budget as a planned capacity spend: $15,000 in Year 1, rising to $55,000 in Year 5.	Modeling marketing as a pure commission instead of a stepped growth budget.

How does break-even change from a lean crew to a full arborist team?

Scenario table

As the crew gets bigger, fixed payroll and support costs rise, so the break-even line moves up even when margin improves. The real test is whether booked work, route density, and crew uptime can keep pace.

Planning assumptions only; actual results can move with weather, job mix, and crew uptime.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean tree-care crew	$47,900	$13,900	$34,000	71%	$0	Lower overhead keeps the break-even bar lighter, but cash gets tight if jobs slip.
Base arborist plan	$60,900	$16,900	$44,000	72%	$0	This is the middle case, but payroll and marketing need steady booked work.
Full-scale arborist team	$90,800	$21,800	$69,000	76%	$0	Scale lifts margin, yet payroll risk and downtime can erase the cushion.

What breaks the break-even plan for this arborist service?

Stress test

Year 1 sits near break-even at about $47,900 revenue, $34,000 fixed costs, and 71% contribution margin. A 10% sales dip, higher overhead, or a 5-point hit to variable spend can flip the month negative fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$47,900	$0 gap	It clears break-even, but there is no cushion.
Revenue shortfall	Revenue falls 10% from the Year 1 plan.	$47,900	$3,400 gap	A modest sales dip turns into a real monthly loss.
Fixed-cost pressure	Fixed costs rise 10% to about $37,400 a month.	$52,700	$4,800 gap	Payroll, insurance, and rent start to squeeze cash.
Margin pressure	Variable spend rises 5 percentage points and margin drops to 66%.	$51,500	$3,600 gap	Fuel spikes, dump fees, and workers' comp can eat the spread.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and margin also weakens.	$52,700	$8,955 gap	Weather delays and downtime can push cash coverage under water.

What should you verify before you buy the arborist truck and lease the yard?

Founder checklist

Treat this as ready only if you can win work at a $150 Year 1 CAC, cover $7,750 of fixed overhead, and keep enough cash for the Month 7 trough. If those three hold, the break-even story is credible; if not, delay the truck and yard lease.

1Launch proof$150 CAC

Verify insurance, local licensing, and your service radius before the first job, then test whether new leads really land at about $150 each.

2Fixed load$7.75K/mo

Hold rent, utilities, fixed insurance, admin, software, vehicle lease, and maintenance at this level before you add marketing spend.

3Margin check71% CM

At Year 1 rates, fuel, disposal, project insurance, and subcontractors use about 29% of revenue, so price storm cleanup separately to protect contribution.

4Payroll base$25K/mo

Make sure booked work can carry the Year 1 wage base before you scale hiring, because the crew load rises fast and payback takes 25 months.

5Equipment uptime4 assets

Confirm the lift truck, chipper, stump grinder, and trailer stay available, secure disposal access, and use subcontractors for oversized removals so payroll does not sit idle.

6Cash runway$668K

Keep enough reserve to survive the Month 7 cash trough, because breakeven does not arrive until Month 8 and the model is cash hungry early on.
