Cost classification

Month 2 break-even only means something if stable overhead stays separate from job-driven spend. Fixed operating overhead is $18,300/month before payroll, while materials, labor, commissions, and shop allocations move with production.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Rent & Utilities	Fixed	Use $12,000/month in fixed overhead for the relevant planning range.	Allocating rent to each home and hiding the monthly nut.
Business Insurance	Fixed	Use $1,500/month as fixed overhead from Month 1 through Month 60.	Treating insurance as a project charge that disappears between builds.
Core Salaried Leadership Payroll	Fixed	Use $25,000/month for the founder, lead designer, and construction manager.	Dropping founder pay to make break-even look easier.
Skilled Builder Team Headcount	Semi-fixed	Model Year 1 at $10,000/month, then step up as FTE rises from 2.0 to 6.0.	Treating added crew as smooth per-unit labor instead of capacity steps.
Direct Materials	Variable	Subtract per home: $3,500, $5,500, $8,000, or $11,000 based on build type.	Using one blended material number when product mix changes.
Direct Construction Labor	Variable	Subtract $2,500 to $8,000 per home based on the build sold.	Double-counting salaried builders and per-unit construction labor.
Sales & Marketing Commissions	Variable	Apply 2.5% of revenue in Year 1, falling to 1.5% by Year 5.	Leaving commissions out because cash payment timing is later.
Equipment Maintenance Allocation	Semi-variable	Apply the 0.2% revenue allocation as shop usage rises with production.	Booking equipment purchases here; capex stays outside operating break-even.

How does break-even shift from a lean mix to full capacity for a tiny house builder?

Scenario table

Break-even moves mostly with mix and payroll. Higher-ticket builds lift revenue fast, but added staff and workshop overhead also raise the monthly fixed load.

Planning figures only; actual break-even changes with build timing, change orders, and overhead mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean mix (Year 1)	$1,290,000	$64,500	$53,300	95.0%	$1,172,200	Revenue is far above the monthly break-even point, so the cushion is strong.
Base mix (Year 2)	$2,059,500	$90,618	$66,008	95.6%	$1,902,874	Break-even stays well covered, but slower job starts would still squeeze cash.
Full-capacity mix (Year 5)	$5,286,000	$200,868	$82,883	96.2%	$5,002,249	The fixed base is still small versus revenue, so break-even risk is low.

What breaks first if sales slow or costs climb?

Stress test

At the base plan, monthly revenue is about $1.075M against a $633k break-even point, so there’s roughly a $442k cushion. That cushion gets thin fast if signed builds slip, materials or labor run hot, or shop overhead climbs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$633k	$442k cushion	Base plan clears break-even by a wide margin.
Revenue shortfall	Monthly revenue falls 20% to $860k.	$633k	$227k cushion	Slower signed builds cut the cushion fast.
Fixed-cost pressure	Fixed monthly costs rise 10% to $586k.	$696k	$379k cushion	Higher shop and payroll overhead push the bar up.
Margin pressure	Variable expenses rise 15% to $196k.	$652k	$423k cushion	Materials, labor, and delivery overruns squeeze contribution.
Combined pressure	Revenue falls 20% while fixed costs rise 10% and variable expenses rise 15%.	$759k	$101k cushion	Weak sales plus higher costs leave little room for delay.

Is your shop, crew, and deposit pipeline ready before you sign the lease?

Founder checklist

Do not sign the shop lease or hire the full crew until signed work can carry at least $633K a month. The model’s cash trough lands in Month 2, so deposits and milestone billing have to come before big buys.

1Signed backlog$633K/mo

Verify signed orders and deposits can support at least $633K a month, because break-even only works if booked work shows up before fixed costs lock in.

2Fixed load$53.3K/mo

Add the $18.3K monthly overhead to about $35K a month of Year 1 wages, and confirm that load stays covered before you add more staff.

3Project margin$2.45K-$26.5K

Price each job above direct unit cost, from $2,450 on The Off Grid Package to $26,500 on The Custom Build, then layer in commission and warranty spend.

4Build capacity10 + 5

Map shop and yard space to Year 1 output of 10 home builds and 5 off-grid packages, and make sure backup suppliers and subcontractors can keep that pace.

5Cash reserve$1.045M

Protect the $1.045M minimum cash need, since the low point lands in Month 2 and early capex can hit before collections catch up.

6Launch demandDeposits first

Require deposits and milestone billing before you order major materials, because the Month 2 cash low point will punish late collections.
