Which demolition service expenses are fixed, variable, semi-variable, or semi-fixed for break-even?

Cost classification

Break-even is only reliable when job-linked costs are kept out of overhead. For this demolition model, first-year variable load starts with disposal at 12.0%, equipment fuel and maintenance at 10.0%, commissions at 4.9%, and project insurance at 3.0% of revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Material Disposal Fees	Variable	Use 12.0% of first-year revenue; it scales with debris volume and job mix.	Treating dump fees as office overhead.
Heavy Equipment Fuel & Maintenance	Variable	Use 10.0% of first-year revenue; it rises with machine hours and job intensity.	Using one fuel average for all jobs.
Sales Team Commissions	Variable	Use 4.9% of first-year revenue; it follows booked work and reduces contribution margin.	Excluding commissions from contribution margin.
Project-Specific Insurance & Bonding	Variable	Use 3.0% of first-year revenue; it is tied to specific demolition projects.	Mixing project bonding with base liability coverage.
Office Rent	Fixed	Use $5,000 per month; it is due even when no jobs are active.	Spreading rent only across winning bids.
General Liability Insurance Base	Fixed	Use $2,500 per month; it is core coverage overhead for the operating base.	Confusing base insurance with project bonding.
Demolition Laborer Payroll	Semi-fixed	Use $220,000 in the first year; four laborer FTEs step up only when crew capacity changes.	Hiring ahead of the signed project pipeline.
Utilities Office	Semi-variable	Use $800 per month as the base, then review usage swings as activity changes.	Ignoring seasonal changes in office and yard usage.

How does break-even move from a lean demolition month to a full-capacity month?

Scenario table

Break-even lands near $102,247 a month when fixed costs are $71,675 and contribution margin is 70.1%. Below that, payroll and overhead outrun booked work; above it, each extra $10,000 of revenue adds about $7,010 of contribution.

Planning assumptions only; actual margins shift with job mix, haul distance, permit costs, and schedule gaps.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean demolition mix	$77,248	$23,101	$71,675	70.1%	-$17,528	Below break-even; booked work still misses payroll and overhead.
Base break-even mix	$102,247	$30,572	$71,675	70.1%	$0	At break-even; one small slip turns profit into loss.
Full-capacity demolition mix	$176,610	$52,806	$71,675	70.1%	$52,129	Well above break-even; extra volume builds cushion, but crew and disposal pressure still matter.

What breaks the break-even plan first for this demolition service?

Stress test

The model is tight at about $102,247 a month, so late starts or cost spikes hit fast. A 10% revenue miss, a 10% jump in fixed costs, or a 5-point rise in variable costs each moves the plan off break-even.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; fixed costs and variable costs stay at plan levels.	$102,247	$0 gap	No cushion; even a small delay can push this negative.
Revenue shortfall	Revenue falls 10% below break-even to about $92,022 a month.	$102,247	$10,225 gap	Permit delays or slow starts quickly eat the buffer.
Fixed-cost rise	Fixed monthly costs rise 10% to about $78,843.	$112,472	$10,225 gap	Payroll and overhead outrun booked work.
Margin pressure	Variable costs rise 5 points from 29.9% to 34.9%.	$110,100	$7,853 gap	Dump fees and fuel push the break-even line up.
Combined pressure	Revenue falls 10%, variable costs rise to 34.9%, and fixed monthly costs rise 10%.	$121,135	$18,934 loss	This mix drives about an $18,934 monthly operating loss.

Founder checklist

Verify that booked or near-booked work, pricing, and crew capacity can support the break-even math before you commit to the first major spend. If they can’t, the Month 8 cash dip makes the launch too thin.

1Launch Demand$102.2K/mo

Verify booked or near-booked revenue can reach the $102,247 monthly break-even line before you buy the first heavy asset.

2Fixed Load$71.7K/mo

Verify fixed overhead, including the $25,000 marketing budget and salaried staff, stays near this level so the break-even target does not creep higher.

3Service Margin70.1% CM

Verify bids still hold about 70.1% contribution after 12.0% disposal fees, 10.0% fuel and maintenance, 4.9% commissions, and 3.0% insurance and bonding in Year 1.

4Crew Ramp280 hrs

Verify the Year 1 mix can cover 160 full-structural, 40 selective, and 80 site-clearing billable hours, and line up backup labor before you hire ahead.

5Cash Trough-$241K

Verify cash can survive the Month 8 low point, or delay noncritical spend until collections and project starts are steady.

6Capex Stage$935K

Verify the excavator, skid steer, attachments, trucks, pickups, and dust system are staged across Month 1 through Month 6, and do not start field work without a safety plan.
