Cost classification

Break-even is only useful if payroll, rent, materials, and marketing are classified correctly. Treat fixed costs as the monthly hurdle, and treat revenue-linked items as the drag on each booked job.

Expense	Cost	Break-Even Treatment	Common Mistake
Owner/Lead Technician payroll	Fixed	$90,000 annual salary, modeled as $7,500 monthly payroll.	Ignore owner pay and overstate break-even profit.
Smart Home Technician I payroll	Semi-fixed	$60,000 annual salary per full-time equivalent; Year 1 uses 1.0 FTE.	Hire ahead of booked installation work.
Office Administrator payroll	Semi-fixed	0.5 FTE in the first year at a $45,000 annual salary.	Bury admin time inside technician labor.
Office Rent	Fixed	$2,500 per month from Month 1 through Month 60.	Lease space before job volume supports it.
Software Subscriptions	Fixed	$800 per month for customer, project, and accounting systems.	Double-count setup fees in monthly break-even.
Smart Device & Hardware Costs	Variable	12% of revenue in the first year, falling to 10% by Year 5.	Confuse markup with margin.
Installation Materials & Consumables	Variable	4% of revenue in the first year for small parts and supplies.	Ignore small parts that repeat on every job.
Marketing & Advertising Spend	Semi-variable	Use 7% of revenue in the first year, with the $15,000 annual budget as acquisition context.	Assume customer acquisition cost stays flat.

How does break-even change across lean, base, and full smart home installation setups?

Scenario table

Break-even climbs as fixed payroll and overhead rise, even though the contribution margin improves from 74% to 80%. So the business needs more booked work in the base and full setups just to stay level.

Planning assumptions only; actual break-even will move with job mix, close rates, and staffing use.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean setup: owner + 1 tech	$28,007	$7,282	$20,725	74%	$0	Best fit early; thin cushion if booked jobs slip.
Base setup: Year 3 scale	$50,887	$11,704	$39,183	77%	$0	Needs steadier job flow after technician hiring.
Full setup: Year 5 scale	$60,021	$12,004	$48,017	80%	$0	Best when utilization and support attach improve.

What breaks the break-even plan for a smart home installation business?

Stress test

Lead flow and labor efficiency are the main breaks here. A 10% revenue dip leaves a $2,072 operating gap, and either a 10% overhead lift or margin slip pushes monthly break-even to about $30k. Callbacks, long drive times, weak booked installs, lower device markup, and CAC above $250 are the warning signs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$28,007	$0 gap	This is the monthly line you need to cover fixed costs.
Revenue shortfall	Revenue falls 10% to $25,206 while costs hold.	$28,007	$2,072 gap	Weak booked installs can turn a small miss into a cash gap.
Fixed-cost increase	Fixed costs rise 10% to about $22,798.	$30,808	$2,801 gap	More overhead means the team needs more monthly revenue just to stand still.
Margin pressure	Variable expenses rise from 26% to 31%, cutting contribution margin to 69%.	$30,036	$2,029 gap	Callbacks, long drive times, or lower device markup can erase the cushion.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 31%.	$33,040	$5,406 gap	This is the danger zone: weaker lead flow and higher costs hit cash at once.

Can you prove enough demand before you lock in the lease, vehicles, and technicians?

Founder checklist

Do the math before you lock in rent, vehicles, and technicians. Break-even lands in Month 5, but the model still needs about $28.8K in monthly booked revenue, a $6.35K fixed-cost base before wages, and enough cash to survive the early ramp.

1Demand Proof$28.8K/mo

Verify booked work reaches about $28.8K a month, or 15 installation-equivalent jobs, before you sign a lease or add staff.

2Fixed Load$6.35K/mo

Keep office, software, insurance, and admin costs at about $6.35K a month before wages, and delay the second vehicle until route density supports it.

3Margin Check74% CM

Check that each job keeps about 74% in contribution margin (CM) after hardware, materials, marketing, and fuel, or volume alone won't fix weak pricing.

4Staffing Ramp2.0 FTE

Make sure you can reach 2.0 technician full-time equivalents (FTE) by Year 2 without late installs or overtime, because service capacity has to rise with demand.

5Cash Cushion$816K

Hold enough reserve for the Month 2 cash trough, since minimum cash lands at $816K before payback starts to help.

6Launch Demand60 cust/yr

Line up referral and partner channels before scaling ads, because $15,000 at a $250 CAC only buys about 60 customers a year, and you should source the $12,000 inventory only after install volume feels steady.
