Which expenses are fixed and which move with sales in a steam curing service?

Cost classification

Break-even works only if direct job spend is separated from recurring overhead. In the first operating year, the model reaches break-even in Month 3, so one bad cost label can distort the required job volume fast.

Expense	Cost	Break-Even Treatment	Common Mistake
Fleet insurance	Fixed	Include $4,500 per month in overhead before calculating required gross margin.	Treating it as a per-job charge, which understates quiet-month risk.
Regional depot lease	Fixed	Include $9,000 per month as recurring facility overhead.	Allocating it only to active jobs instead of carrying it every month.
Annual marketing budget	Fixed	Use the first-year budget of $125,000, or about $10,417 per month, as planned overhead.	Confusing customer acquisition cost with a sales commission that rises per job.
Fuel and consumables	Variable	Deduct 12% of revenue in the first year before contribution margin.	Modeling fuel as flat even though longer cures and more billable hours burn more inputs.
Equipment maintenance and parts	Variable	Deduct 6% of revenue in the first year because the model ties it to job volume.	Parking all maintenance in overhead and overstating contribution margin.
Field crew travel and subsistence	Variable	Deduct 5% of revenue in the first year as jobs require more site travel.	Using one average travel number for nearby and remote projects.
Logistics and dispatch fees	Variable	Deduct 3% of revenue in the first year as dispatch activity scales with booked work.	Ignoring dispatch drag when project count rises faster than pricing.
Payroll staffing bands	Semi-fixed	Model payroll in hiring steps, from 9 full-time employees in Year 1 to 32 in Year 5.	Smoothing headcount as a pure revenue percentage instead of adding crews in blocks.

How does break-even change from lean launch to full scale for a steam curing service?

Scenario table

Break-even gets easier as the business moves from launch to full scale because utilization rises, variable cost share falls from 26.0% to 21.2%, and fixed cost coverage widens. The full case gives the cleanest cushion.

Planning cases only; actual results will move with job mix, travel, fuel, and crew downtime.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$478k	$124k	$93k	74.0%	$261k	Revenue runs 3.8x above break-even, so launch still needs tight crew use.
Base scale case	$1.54m	$363k	$165k	76.4%	$1.01m	Revenue runs 7.7x above break-even, giving a solid cushion.
Full mature case	$2.60m	$552k	$260k	78.8%	$1.79m	Revenue runs 8.7x above break-even, so scale has the widest cushion.

What breaks the break-even plan for this steam curing service?

Stress test

The launch clears break-even by a wide margin in the base case, but Month 4 cash still drops to -$499k. The main pressure points are lower site utilization, higher fuel and parts, and any creep in overhead.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,391k	$3,392k cushion	Strong margin, but Month 4 cash still dips to -$499k.
Revenue shortfall	Revenue falls 20% to $3,827k.	$1,391k	$2,436k cushion	Still above break-even, but profit thins fast.
Fixed-cost pressure	Fixed overhead rises 15% to $1,184k.	$1,600k	$3,183k cushion	Higher overhead lifts the break-even line, but the plan still clears it.
Margin pressure	Variable expenses rise 5 points and margin drops to 69%.	$1,492k	$3,291k cushion	Fuel, travel, and parts pressure the model, but break-even stays manageable.
Combined pressure	Revenue falls 20%, variable expenses rise to 31%, and fixed costs rise 10%.	$2,319k	$1,508k cushion	Still profitable, but the Month 4 cash low remains the early warning.

Can you prove demand, pricing, and cash cover the steam fleet before you commit?

Founder checklist

Do not buy the steam fleet until booked work can cover about $125K a month and the Month 4 cash trough. The model reaches break-even in Month 3, but it still shows about -$499K minimum cash, so reserve funding has to be in place first.

1Demand floor$125K/mo

Verify pipeline demand can support this revenue level, or the Month 3 break-even target will slip.

2Launch capex$1.545M

Confirm you can fund the steam units, vehicles, nozzles, sensors, tooling, IT, depot fitout, and compliance gear before work starts.

3Rate mix74% CM

Check that the $450, $550, and $350 hourly mix still clears the 26% variable cost load and holds the blended rate at $455.

4Crew ramp275 hrs/mo

Verify field crew, access, dispatch, and safety coverage can handle this billable volume without missed jobs or overtime spikes.

5Fixed load$92.5K/mo

Make sure insurance, depot lease, payroll, software, legal, utilities, and lab spend stay covered before receivables stabilize.

6Cash trough-$499K

Verify reserve cash can absorb the Month 4 low point, because payback does not arrive until Month 11.
