Which expenses are fixed, variable, or capacity-driven for a reverse engineering service?

Cost classification

The model reaches break-even in Month 17, but only if recurring overhead and project-tied costs are split cleanly. Misclassifying 8.0% lab fees or 5.0% commissions as fixed will overstate margin as revenue grows.

Expense	Cost	Break-Even Treatment	Common Mistake
Secure Engineering Lab Rent	Fixed	Include $12,500 per month in overhead from Month 1 through Month 60.	Treating lab rent as project-driven instead of a monthly hurdle.
Professional computer-aided design software licenses	Fixed	Include $4,200 per month before calculating profit per billable hour.	Ignoring licenses until headcount grows, which understates early break-even.
Year 1 payroll for modeled operating team	Semi-fixed	Use $625,000 per year, about $52,083 per month, until staffing steps up.	Modeling payroll as fully variable when the team is hired ahead of revenue.
External Lab Testing Fees	Variable	Subtract 8.0% of revenue in the first year as project volume rises.	Burying outsourced testing in overhead instead of tying it to jobs.
Cloud Computing and Data Storage	Variable	Apply 3.0% of first-year revenue as usage tied to analysis work.	Leaving usage-heavy storage out of gross margin.
Sales Commissions	Variable	Deduct 5.0% of revenue in each year before covering fixed overhead.	Adding commissions to payroll and overstating contribution margin.
Project Travel and Logistics	Variable	Apply 4.0% of first-year revenue for travel and job delivery work.	Averaging travel into rent or admin expense, hiding project drag.
Annual Marketing Budget	Fixed	Spread the first-year $60,000 budget as about $5,000 per month.	Using customer acquisition cost alone and missing committed monthly spend.

How does break-even change across lean, base, and full utilization?

Scenario table

Lower utilization pushes revenue down faster than fixed engineering costs can flex. Here’s the quick math: the base case sits on break-even, the lean case stays deep in the red, and the full case adds a small cushion.

Planning cases only; actual results will move with project mix, utilization, subcontracting, and turnaround speed.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean utilization case	$576K	$115K	$823K	80.0%	-$362K	Still below break-even; cash burn stays high.
Base break-even case	$1,029K	$206K	$823K	80.0%	$0	At break-even; any delay or rework hurts fast.
Full utilization case	$1,263K	$237K	$844K	81.0%	$182K	Above break-even; stronger throughput gives a small cushion.

What breaks the break-even plan for this reverse engineering service?

Stress test

Break-even is most exposed to slow signed work, rising marketing overhead, and travel-heavy lab jobs. If project flow slips while fixed and variable costs stay high, the Month 17 target gets hard to protect.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.03M	$453K gap	Year 1 revenue still sits below breakeven.
Revenue shortfall	Signed work stays at $576K and pipeline stays weak.	$1.03M	$453K gap	Slow deal flow leaves a wide gap.
Fixed-cost increase	Year 2 marketing rises from $60K to $85K annually.	$1.05M	$479K gap	Higher overhead lifts the break-even bar.
Margin pressure	External lab testing and travel stay at Year 1 levels.	$1.06M	$484K gap	Thin contribution keeps break-even high.
Combined pressure	Year 1 revenue meets Year 2 fixed costs and margin does not improve.	$1.08M	$508K gap	Weak flow plus cost creep pushes breakeven out.

What should you verify before you commit to the lab, staff, and scanners?

Founder checklist

Before you commit, prove the pipeline can cover about $82.3K a month of fixed overhead and still reach the Month 17 break-even path. If demand, pricing, or utilization comes in light, the model slips fast because the early cost base is heavy.

1Signed pipeline12 projects/mo

Do not add space or staff until you can show enough signed work to keep 12 active projects moving each month and hold marketing near $50K/mo until conversion data improves.

2Fixed load$82.3K/mo

Check that lab rent, software, utilities, maintenance, insurance, IT, payroll, and marketing stay near this monthly burn before you sign a long commitment.

3Price floor$86K+

Keep the Year 1 average project value above the $86K weighted base, or the business will struggle to absorb setup cost and still earn a margin.

4Billable load45.0 hrs

Track engineer utilization against 45 billable hours per active customer in Year 1 so the staffing ramp stays tied to real billable work.

5Cash cushion$28K, M18

Hold enough cash to survive the Month 18 low point of $28K, because break-even lands in Month 17 and the buffer is thin.

6Capex phase$75K / $45K / $120K

Phase the scanner, structured light system, and CMM buys so you do not lock in the full equipment stack before demand and delivery are proven.
