Which temporary structure rental expenses are fixed, and which move with sales?

Cost classification

Break-even gets reliable only when job-linked costs stay out of overhead and monthly commitments stay out of contribution margin. Here’s the quick split: revenue percentages reduce margin; rent, systems, and salaried teams set the monthly hurdle.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse and Yard Lease, $12,500/month	Fixed	Treat as monthly overhead from Month 1 through Month 60.	Don’t treat yard rent as a per-job charge.
Marketing and SEO Management, $3,500/month	Semi-fixed	Keep in overhead unless a campaign spend clearly scales with bookings.	Don’t call every lead spend variable.
Utilities and Facility Security, $2,100/month	Semi-variable	Model the base facility load in overhead and watch seasonal yard use.	Don’t ignore higher use during busy setup months.
Fleet Maintenance and Registration, $2,800/month	Semi-fixed	Use as overhead until fleet size or repair spikes force a step-up.	Don’t bury recurring fleet obligations in job margin.
Fuel and Transportation Logistics, 5.0% of revenue in first year	Variable	Deduct from contribution margin as a direct delivery input.	Don’t average long-haul and local jobs blindly.
Sales Commissions, 4.0% of revenue	Variable	Deduct from contribution margin because it moves with closed sales.	Don’t include base salaries in commission expense.
Subcontracted Specialized Services, 6.5% of revenue in first year	Variable	Treat as direct setup support tied to rental revenue.	Don’t forget specialized lifts, rigging, or outside crews.
Salaried management and crew payroll, $500,000/year in first year	Fixed	Use as payroll overhead for the first operating year.	Don’t classify full-time supervisors as per-booking labor.

How does break-even shift from a lean launch mix to a base case and a full-utilization month?

Scenario table

Break-even improves as the mix shifts from launch to ramp to full use. Event rentals lift ticket size, construction modules keep weekday slots busy, and ancillary packages add margin without much extra overhead.

Planning figures only; actual results will move with booking mix, timing, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch mix	$114.5k	$21.2k	$68.6k	81.5%	$24.7k	Thin cushion; a missed week can wipe out profit.
Base ramp mix	$166.3k	$29.1k	$74.0k	82.5%	$63.1k	Break-even is covered, with room for timing slippage.
Full utilization mix	$239.3k	$38.3k	$94.4k	84.0%	$106.6k	Higher payroll still leaves a wide cushion.

What breaks the break-even plan for temporary structure rentals?

Stress test

The plan holds only if revenue stays near $1,145k and direct costs stay at 18.5%. A 10% booking miss or a $10k monthly overhead hike cuts the cushion fast; mix both and the buffer nearly disappears.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$841k	$304k cushion	The base plan clears break-even with room to spare.
Revenue shortfall	Revenue drops 10%.	$841k	$190k cushion	A 10% booking miss strips $114k from the cushion.
Fixed-cost increase	Add $10k/month to yard, insurance, or fleet.	$990k	$155k cushion	Overhead growth burns through cash even if sales hold.
Margin pressure	Direct expenses rise 5 points to 23.5%.	$897k	$248k cushion	Fuel, subcontracting, or overtime lift break-even fast.
Combined pressure	Revenue drops 10%, direct expenses rise 5 points, and fixed costs add $10k/month.	$1,054k	$23k gap	One delay or overtime spike can push the plan under water.

What should you verify before locking the lease, fleet, and first hires for a temporary structure rental business?

Founder checklist

Model break-even lands in Month 2, but you still need demand, cash, and setup capacity to reach it cleanly. Keep the Month 8 cash dip of negative $161K and the 37-month payback in view before you sign the bigger commitments.

1Booking pace10-11/mo

Verify at least 10 to 11 bookings a month before launch-scale spend, or the yard and fleet will sit underused.

2Fixed burn$68.6K/mo

Confirm the lease, insurance, marketing, software, utilities, fleet upkeep, and Year 1 wages total about $68.6K a month, because that is the fixed load you must cover.

3Margin mix81.5% CM

Check that the Year 1 mix still leaves about 81.5% contribution margin after subcontracted services, cleaning, fuel, and commissions, so each rental helps fund overhead.

4Launch gate$1.25M

Phase the $1.25M capex across inventory, modular units, trucks, forklifts, racking, ancillary stock, and tooling, and do not scale marketing until delivery and setup can handle overlapping installs.

5Crew plan6 FTE

Map the first-year team at 6.0 FTE and make sure that crew can cover sales, operations, warehouse work, and installs before you accept more volume.

6Cash test-$161K / 37 mo

Hold reserve for the Month 8 cash trough and pressure-test the 37-month payback, because a short cash cushion will force a slowdown.
