Which fire pit installation expenses stay fixed, and which move with sales?

Cost classification

Break-even works only if fixed overhead and job-level expenses stay separate. In the first operating year, this model reaches break-even in Month 2, so misclassifying materials, permits, or referral fees can overstate margin fast.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop and Showroom Lease	Fixed	Use $4,500 per month as baseline overhead before counting any project margin.	Spreading rent across jobs and making margin look cleaner than cash flow.
General Liability Insurance	Fixed	Use $1,200 per month in fixed overhead for the full planning period.	Treating insurance as job-level expense and understating monthly break-even sales.
Design Software Subscriptions	Fixed	Use $350 per month as recurring overhead tied to design capacity, not units sold.	Dropping small subscriptions from break-even because they feel immaterial.
Natural Stone Blocks and Burner Systems	Variable	Assign direct materials to each installed unit, such as $800 for stone blocks and listed burner components.	Burying materials inside overhead instead of reducing contribution margin per project.
Gas Fitter Subcontractor	Variable	Model as 2.0% of revenue, so the expense rises with completed installation sales.	Forgetting subcontractor work when pricing custom jobs with gas connections.
Permit Filing Fees	Variable	Model as 1.0% of revenue and include it in contribution margin math.	Parking permits in admin overhead and overstating job profitability.
Equipment Fuel	Semi-variable	Track the modeled 0.5% of revenue, then compare it with actual job-site travel and equipment use.	Treating fuel as fixed when longer hauls and heavier installs raise usage.
Vehicle Insurance and Maintenance	Semi-fixed	Use $850 per month until added trucks, crews, or operating scale force a step-up.	Assuming the monthly amount stays flat after capacity expands.

How does break-even move from lean to base to full fire pit installation volume?

Scenario table

Higher volume lifts revenue faster than variable cost, so each step up improves cushion. Still, new hires raise the fixed-cost floor, so the real risk is not demand alone, it’s keeping the crew loaded.

Planning assumptions only; actual mix, labor timing, and permit delays can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1	$107.5k	$30.9k	$33.1k	72.0%	$43.5k	Clears break-even, but the cushion is still tight.
Base Year 3	$190.4k	$54.5k	$56.0k	71.4%	$79.9k	Comfortable cushion, though the fixed floor is higher.
Full Year 5	$285.3k	$78.6k	$72.3k	72.4%	$134.3k	Strong cushion if volume lands, but crew costs stay high.

What breaks the break-even cushion for a fire pit installation business?

Stress test

The base plan clears break-even with room to spare, but the cushion shrinks fast if bookings slow, permits drag, or labor and freight costs rise. A 20% revenue dip still works, yet it cuts profit buffer hard.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	First-year revenue holds at $1,075k with a 74.9% contribution margin and $331k fixed costs.	$442k	$633k cushion	Base case sits well above break-even.
Revenue shortfall	Revenue drops 20% to $860k, with margin held at 74.9%.	$442k	$418k cushion	Demand softens, but the plan still clears break-even.
Fixed-cost pressure	Fixed costs rise 10% to about $364k.	$486k	$589k cushion	Overhead creep hurts, but the business still has room.
Margin pressure	Contribution margin compresses 5 points to 69.9%.	$474k	$601k cushion	Permit delays, rework, and supplier deposits can squeeze profit fast.
Combined pressure	Revenue drops 20%, margin falls to 69.9%, and fixed costs rise 10%.	$521k	$339k cushion	Still above break-even, but unlisted items can eat the $237k profit cushion.

Is this fire pit installation business ready to sign the lease and buy equipment?

Founder checklist

Don’t lock in the workshop or equipment until the first-year mix still clears Month 2 break-even with the planned margins, crew, and cash on hand. If any of these checks miss, pause the commitment.

1Materials Quotes$750-$3.4K/job

Verify stone, burner, steel, concrete, media, and gas-kit quotes against the first-year mix, because the average ticket is about $11.7K and the job stack varies a lot.

2Variable Spend14% of revenue

Check that referral commissions, marketing, disposal, fuel, permits, and delivery stay near 14% of sales, which leaves about 86% contribution before fixed costs.

3Monthly Overhead$33.1K/mo

Make sure workshop rent, insurance, software, utilities, and year-one payroll really total about $33.1K a month, since that is the load break-even must cover.

4Crew Capacity110 installs

Confirm the owner, master mason, and two installers can finish 110 first-year installs, or the revenue plan will outrun field capacity.

5Cash Reserve$1.116M

Protect the Month 2 minimum cash need of $1.116M before you sign anything, because capex hits early and the trough comes fast.

6Launch DemandDeposits first

Require deposits before materials are ordered, and do not add the project coordinator in Month 13 or the sales liaison in Month 25 until booked work can pay for the payroll step-up.
