Cost classification

Break-even gets more reliable when stable overhead is separated from job-level spending. If utilities, rework, scrap, or delivery get buried in overhead, the Month 25 break-even target can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Rent	Fixed	Use $4,500 per month in fixed overhead.	Allocating rent per gate, rail, or bracket.
Business Insurance	Fixed	Use $350 per month in fixed overhead.	Moving it with revenue instead of time.
Accounting & Legal Fees	Fixed	Use $600 per month in fixed overhead.	Treating routine admin support as job-level spending.
Equipment Maintenance Contracts	Semi-fixed	Use $700 per month until added equipment changes capacity.	Spreading the contract across every unit as variable.
Salaried Welders and Design Engineer	Semi-fixed	Add salary by staffing step, not by each finished job.	Modeling full-time labor like hourly piecework.
Raw Steel, Aluminum, and Tubing	Variable	Apply per unit based on the product built.	Burying scrap and rework inside overhead.
Sales Commissions	Variable	Use 5.0% of first-year revenue, then the model’s lower yearly rates.	Forgetting commissions when pricing custom work.
Utilities Base and Power Use	Semi-variable	Keep the $800 base fixed and add usage for heavier production.	Treating the full utility bill as fixed.

How does break-even change across lean, base, and full welding shop setups?

Scenario table

Here’s the quick math: the lean case sits close to the line, the base case reaches the model’s Month 25 break-even path, and the full case builds the widest cushion as volume and staffing rise. Job mix matters too, because high-ticket beams carry more dollars than low-ticket brackets.

Planning cases use model assumptions and core metrics, so they show direction, not a guarantee.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$54.6k	$16.5k	$39.4k	69.8%	-$1.3k	Close to break-even, so demand proof still matters.
Base shop-plus-truck case	$86.2k	$25.6k	$48.2k	70.3%	$12.4k	Clears the Month 25 break-even signal and starts to add cushion.
Full multi-welder case	$120.8k	$32.8k	$48.2k	72.8%	$39.8k	Strongest cushion once full welder staffing and higher throughput are in place.

What breaks the break-even plan for this welding company?

Stress test

The plan has a thin cushion: about $54.6K of monthly revenue versus roughly $50K to break even. A 10% sales drop, $5K more overhead, or a 5-point margin hit can push it under.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$50K	$4.6K cushion	Thin cushion; a small miss can erase it.
Revenue shortfall	Monthly revenue falls 10% to about $49.1K.	$50K	$0.9K gap	A modest sales dip puts the plan below break-even.
Fixed-cost pressure	Monthly overhead rises by $5K to $44.4K.	$56.3K	$1.7K gap	Extra overhead eats the cushion fast.
Margin pressure	Contribution margin drops 5 points to 73.9%.	$53.4K	$1.2K cushion	Waste, fuel, or rework can wipe out the slack.
Combined pressure	Revenue falls 10%, overhead rises $5K, and margin drops 5 points.	$60.1K	$11.0K gap	Three hits together create a clear operating gap.

Can this welding shop cover the lease, equipment, and next hire before you commit?

Founder checklist

Before you sign the lease or buy equipment, verify that booked work can cover about $39.4K a month of fixed load. At roughly 80% contribution margin, that needs about $49K in monthly revenue, and the model still does not break even until Month 25. Payback takes 52 months.

1Booked Work$54.6K/mo

Verify the pipeline can hold first-year modeled revenue of $655K, or about $54.6K a month, before you lock in the shop.

2Monthly Burn$39.4K/mo

Check that rent, utilities, insurance, admin, maintenance, and payroll can run at that burn rate without draining cash too fast.

3Price Cover80% CM

Confirm quotes cover direct steel, welding labor, delivery, sales commissions, and rework cash, because that is what pays the fixed load.

4Staffing Ramp5.5 FTE

Make sure lead fabrication, one skilled welder, half of design support, sales, admin, and owner time can actually run at plan.

5Cash Reserve$914K

Hold enough cash to survive the modeled low point of $914K in Month 36, because break-even lands in Month 25 and payback takes 52 months.

6Go-Live Gate$242K

Lock the $242K capex plan, supplier terms, storage, reorder points, scrap tracking, power, ventilation, safety gear, and inspection needs before any marketing spend.
