Which cement silo cleaning expenses are fixed, and which move with sales?

Cost classification

Fixed overhead hits before the first job, while supplies, fuel, travel, and commissions move with revenue. Classifying them correctly keeps the Month 26 break-even from looking earlier than the cash really allows.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse and Office Rent	Fixed	Include $7,500 per month in overhead.	Allocating it only to active jobs.
General Liability and Workers Comp Insurance	Fixed	Include $14,000 per month before revenue.	Treating required coverage as optional.
Safety Compliance and EHS Monitoring	Fixed	Include $2,500 per month in overhead.	Burying safety monitoring inside training.
Waste Disposal and Consumables	Variable	Use 9% of revenue in the first year.	Using a flat monthly amount.
Equipment Fuel and Repairs	Variable	Use 6% of revenue in the first year.	Ignoring utilization as jobs increase.
Travel and Mobilization Logistics	Variable	Use 10% of revenue in the first year.	Underpricing distant routes.
Sales Commissions	Variable	Use 4% of revenue as volume grows.	Including commissions in fixed payroll.
Field Technician and Assistant Payroll	Semi-fixed	Plan as crew capacity added in steps.	Assuming labor moves perfectly per job.

How does break-even shift from lean to base to full operations for a cement silo cleaning service?

Scenario table

Lean is still loss-making, base is the first break-even case, and full adds a real cushion. Month 26 is the pivot, when fixed-cost coverage finally catches up to contribution.

Planning cases only; actual results will move with contract mix, pricing, and field costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$39.5k/mo	$11.5k/mo	$97.8k/mo	71%	-$69.8k/mo	Still below break-even; the fixed load is too heavy.
Base operating case	$130.1k/mo	$34.5k/mo	$37.1k/mo	73.5%	$58.5k/mo	Turns positive around Month 26 and starts covering overhead.
Full-scale case	$244.1k/mo	$58.6k/mo	$40.4k/mo	76%	$145.1k/mo	Strong cushion; scaled contract density supports break-even.

What breaks the break-even plan for a cement silo cleaning service?

Stress test

The base plan has a small monthly cushion, so a 10% revenue dip or a $10,000 jump in fixed overhead can erase it fast. Margin pressure is the quiet risk: more travel, overtime, downtime, or insurance can push the model to breakeven or worse.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Uses the Year 3 average revenue, a 73.5% contribution margin, and $89,250 in fixed monthly costs.	$121,429	$8,655 cushion	Only a thin buffer before losses start.
Revenue shortfall	Monthly revenue falls 10% from the Year 3 average.	$121,429	$4,354 gap	Fewer contracts can wipe out the cushion.
Fixed-cost pressure	Fixed monthly overhead rises by $10,000.	$135,034	$4,951 gap	Insurance or staffing creep pushes break-even higher.
Margin pressure	Contribution margin falls 5 points to 68.5%.	$130,292	$209 gap	Longer travel, overtime, or downtime nearly erase the buffer.
Combined pressure	Revenue falls 10%, margin falls to 68.5%, and fixed costs rise by $10,000.	$144,964	$27,889 gap	Several small hits together push the plan well below break-even.

What should you verify before signing the yard lease and buying the first equipment package?

Founder checklist

Do not sign the yard lease or buy the first equipment package until the model can show enough signed or near-signed work to reach about $126K in monthly revenue. The break-even path only works if demand, margin, safety, and crew setup are ready before Month 26.

1Demand Proof$126K/mo

Verify signed or near-signed plant, contractor, and maintenance leads can cover the monthly break-even revenue before you commit to the yard lease.

2Route Radius10% rev

Verify the service area is tight enough to keep travel and mobilization near the Year 1 10% revenue assumption, or margin will slip fast.

3Margin Mix71% CM

Verify your job mix can sell at the Year 1 ticket sizes of $6.6K, $7.2K, $1.8K, and $1.4K so contribution stays near plan.

4Fixed Load$89.25K/mo

Verify you can carry rent, insurance, safety, software, utilities, and wages before owner pay, and keep the $462K equipment and setup buy separate from monthly break-even math.

5Cash Cushion-$1.382M

Verify you can survive the projected low point in Month 25, because the model does not reach break-even until Month 26.

6Ramp Ready6→12 FTE

Verify insurance, gas detection, confined-space gear, and crew scheduling are ready before you scale field staffing, or the launch will choke on unsafe throughput.
