Which gutter guard installation expenses are fixed, and which move with sales?

Cost classification

Break-even gets cleaner when overhead is split from job-linked spend. In this model, Month 3 break-even depends on covering fixed monthly support first, then managing materials, field labor, fuel, and lead spend as revenue grows.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse and Storage Rent	Fixed	$3,200 monthly overhead from Month 1 through Month 60.	Treating storage as per-job spend.
General Liability and Workers Comp	Fixed	$1,450 monthly coverage required before job volume matters.	Excluding required insurance from overhead.
CRM and Scheduling Software	Fixed	$350 monthly system spend for estimating, dispatch, and follow-up.	Tying software only to job count.
Professional Accounting Services	Fixed	$600 monthly admin support included in base overhead.	Leaving bookkeeping out of break-even.
Installation Materials and Hardware	Variable	18% of first-year revenue, moving directly with installed jobs.	Underpricing material waste.
Direct Field Labor Compensation	Variable	8% of first-year revenue tied to production work.	Mixing field labor with salaried management.
Fuel and Vehicle Maintenance	Variable	3% of first-year revenue, driven by routes and job volume.	Missing route density impact.
Annual Marketing Budget	Semi-fixed	$45,000 in the first year, or about $3,750 per month.	Cutting lead flow before fixed costs are covered.

How does break-even change from a lean launch to a full crew buildout?

Scenario table

The main swing is fixed staffing, not margin. Lean stays close to break-even, base builds a clear cushion, and full mode still works if lead flow keeps up.

Planning assumptions only; actual results will move with pricing, job mix, and staffing pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$45.1k	$13.5k	$31.0k	70.0%	$600	Near break-even, so launch pacing matters.
Base one-crew-plus-admin	$161.0k	$48.3k	$31.0k	70.0%	$81.7k	Strong cushion for a steady operating plan.
Full growth buildout	$304.5k	$87.7k	$42.0k	71.2%	$174.8k	Break-even sits near $59k, so lead flow has room to fund the step-up.

What breaks first if bookings slow or costs climb for this gutter guard service?

Stress test

The base plan has room, but the cushion shrinks fast if sales dip, fixed overhead rises, or crews start discounting to win work. The tightest risk is margin loss plus slower booked revenue.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$44,300	$81,700 cushion	Healthy room for normal swings.
Revenue shortfall	Monthly revenue is 20% lower at $128,800.	$44,300	$59,200 cushion	Still above break-even, but lead flow matters.
Fixed-cost pressure	Fixed overhead is 15% higher at $35,650 a month.	$50,900	$77,050 cushion	Overhead pushes break-even up fast.
Margin pressure	Variable expenses rise to 35%, so contribution falls to 65%.	$47,700	$73,650 cushion	Discounting, overtime, or fuel spikes eat margin.
Combined pressure	Revenue is 20% lower, fixed costs are 15% higher, and variable expenses rise to 35%.	$54,800	$48,100 cushion	This is the tightest case; route density matters most.

Is the average job value high enough to cover the first crew before you buy trucks and lock in payroll?

Founder checklist

Before you buy trucks or add payroll, make sure the model can hold a roughly $31,000 monthly fixed load and still survive the Month 2 cash trough of $795,000. If the average job stays near $1,610 and CAC starts near $225, the Month 3 break-even path is credible.

1Job Value$1,610/job

Verify your first-year mix still produces about $1,610 per job, because weaker ticket size makes it harder to cover fixed costs.

2Fixed Load$31K/mo

Check that overhead and payroll stay close to the modeled $31,000 a month, or the lease and salary load will outrun early demand.

3Margin Mix70% CM

Confirm supplier pricing and field productivity can hold materials near 18% of revenue, labor near 8%, and fuel near 3%, which leaves about 70% contribution in Year 1.

4Crew Ramp1 crew

Keep the opening team at one lead tech, one assistant, and half-time sales coverage, then delay the second truck until lead flow can keep that crew busy.

5Cash Cushion$795K

Hold the $795,000 cash cushion through Month 2, because that is the tightest point in the model and cash can get thin before break-even.

6Lead Cost$225 CAC

Verify customer acquisition cost (CAC) starts near $225 in Year 1 and that lead flow is strong enough to keep the first truck booked before you add fixed salaries.
