Which lanai enclosure expenses are fixed, and which move with each sale?

Cost classification

Your break-even is only reliable if fixed overhead stays separate from per-project spend. Rent, fleet maintenance, and salaried payroll create the monthly floor; materials, commissions, lead generation, and job-linked trade costs move with sales.

Expense	Cost	Break-Even Treatment	Common Mistake
Design Studio Rent	Fixed	Include $6,500/month in fixed overhead from Month 1 through Month 60.	Spreading rent across jobs as if it disappears in slow months.
First-year salaried operating payroll	Fixed	Include $445,000/year, or about $37,083/month, before measuring project contribution.	Treating salaried managers, designers, foremen, and admin staff like variable job labor.
Vehicle Fleet Maintenance	Fixed	Carry $2,500/month as fixed operating overhead, separate from job-site rental usage.	Burying truck costs inside generic overhead, then missing the real monthly cash floor.
Aluminum Framing Materials	Variable	Apply $2,500 for each Basic Lanai sold because this spend rises with unit volume.	Using one blended material rate and losing sight of margin by product type.
Sales Commissions	Variable	Deduct 5.0% of revenue in every forecast year when calculating contribution margin.	Calculating break-even on gross revenue and adding commissions after the fact.
Marketing and Lead Gen	Variable	Use 4.0% of revenue in the first year, stepping down to 2.0% by Year 5.	Burying lead generation in overhead even though it scales with booked work.
Equipment Rental Allocation	Semi-variable	Model the 0.8% revenue allocation as usage-linked field support, separate from fixed fleet maintenance.	Rolling rental usage into truck costs and hiding project-level margin pressure.
Construction Foreman Capacity	Semi-fixed	Start with two foremen at $65,000 each, then add staffing in steps as project volume outgrows crew capacity.	Smoothing foreman hires across every job and ignoring idle crew time between projects.

How do lean, base, and full lanai schedules change break-even risk?

Scenario table

Break-even is easiest to miss in the lean plan because fixed overhead stays close to the floor. The base plan gives the cleanest cushion, and the full plan adds more profit but needs tighter crew and schedule control.

Planning figures only; they do not include taxes, debt service, owner draw, or working capital timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean lanai mix	$81.5k	$17.0k	$49.5k	79.2%	$15.0k	At 2 jobs a month, the cushion is thin and delays matter.
Base year 1 plan	$366.7k	$76.1k	$49.5k	79.2%	$241.0k	Comfortable coverage; break-even sits well below this pace.
Full year 2 capacity	$533.9k	$114.3k	$61.2k	78.6%	$358.4k	High output is profitable, but crew and scheduling discipline matter.

What would push this lanai contractor below break-even?

Stress test

The plan has a wide Year 1 cushion: $4.4M revenue versus about $890k break-even. Contribution margin means revenue left after variable project costs, and the model still clears break-even even if bookings fall 25% or overhead rises 20%.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in the Year 1 plan.	$890k	$3.5M cushion	Healthy buffer in the opening year.
Revenue shortfall	Bookings run 25% below plan.	$890k	$2.4M cushion	Sales slippage cuts the cushion, but break-even stays far below plan.
Fixed-cost increase	Fixed overhead rises 20% from the Year 1 run rate.	$1.1M	$3.3M cushion	Rent, fleet, and admin spend need tight control.
Margin pressure	Variable expenses take 5 more points of revenue.	$962k	$3.4M cushion	Materials and rework are the first margin leak.
Combined pressure	Bookings fall 25%, fixed costs rise 20%, and margin slips 5 points.	$1.15M	$2.1M cushion	Still above break-even, but lead costs over 4% or warranty pressure can narrow the buffer fast.

Can this lanai contractor prove break-even before the first big spend?

Founder checklist

If you can line up 2 projects a month at launch and hold a 9-project monthly average in Year 1, the Month 2 break-even looks real. The gate is cash and setup: $1.082M minimum cash, $270K capex, and a $49.5K monthly overhead base.

1Demand Floor2→9/mo

Verify signed work and qualified leads can support at least 2 projects a month now and 9 a month on average in Year 1, or break-even slips past Month 2.

2Cash Cushion$1.082M

Confirm you can fund the Month 1 cash need before major spend, because the low cash point hits at launch.

3Capex Stack$270K

Check the first spend bundle covers the showroom, trucks, tools, IT, workstations, racking, furniture, and safety gear without starving jobs.

4Fixed Load$49.5K/mo

Verify rent, insurance, vehicles, software, utilities, admin, and Year 1 wages stay near this base so fixed cost does not outrun early revenue.

5Margin Mix~68% CM

Test that the mix of basic, screened, premium kitchen, all season, and custom jobs still leaves enough contribution after materials, sales commissions, and lead gen.
