Which expenses are fixed, and which move with sales for a measurement-system study service?

Cost classification

In the first year, delivery-linked expenses total 27% of revenue: travel 8%, lab fees 5%, project software 4%, and referrals 10%. Keep payroll and monthly overhead fixed; rework can push variable spend higher and delay Month 6 break-even.

Expense	Cost	Break-Even Treatment	Common Mistake
Analyst and admin payroll	Fixed	Include in monthly overhead for the relevant staffing plan.	Treating salaried staff as job-by-job delivery spend.
Office Rent	Fixed	Use $3,500 per month in fixed overhead.	Leaving rent out because consultants work at client sites.
Insurance Liability	Fixed	Use $850 per month in fixed overhead.	Allocating liability coverage only to booked projects.
Annual Marketing Budget	Fixed	Use $45,000 per year, or $3,750 per month.	Confusing planned budget with customer acquisition cost.
Travel and Subsistence	Variable	Model at 8% of first-year revenue.	Treating client-site travel like fixed overhead.
Sub-Contractor Lab Fees	Variable	Model at 5% of first-year revenue.	Forgetting outside lab work rises with booked studies.
Software Licensing per Project	Variable	Model at 4% of first-year revenue.	Putting per-project licenses into general subscriptions.
Referral Commissions	Variable	Model at 10% of first-year revenue.	Using gross revenue before commission drag in break-even.

How does break-even shift as booked Gauge R&R studies move from lean to full utilization?

Scenario table

The mix matters because the weighted average study fee is $6,978, while variable delivery expense stays at 27% of revenue. Fixed monthly costs are $39,558, so the break-even signal lands at 8 booked studies.

Planning assumptions only; actual results will move with the study mix, delivery costs, and booking pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean service mix	$41,868	$11,304	$39,558	73%	-$8,994	Below break-even; bookings still leave a gap.
Base case	$55,824	$15,073	$39,558	73%	$1,193	Near break-even; one more study adds cushion.
Full-utilization month	$83,736	$22,609	$39,558	73%	$21,569	Healthy cushion; fixed costs are clearly covered.

What pressures the break-even plan for a measurement system analysis service?

Stress test

The base plan has only a $1,193 cushion, so a 15% revenue drop, a 10% fixed-cost jump, or a 5-point margin hit can push it below break-even. Late bookings, extra client-site days, lab rework, and low analyst use are the key watchouts.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Base case revenue is $55,824 with 27% variable expense and $39,558 fixed costs.	$54,631	$1,193 cushion	Late bookings can wipe out the cushion.
Revenue shortfall	Revenue drops 15% to $47,450.	$52,369	$4,919 gap	Fewer studies quickly eat the cushion.
Fixed-cost pressure	Fixed costs rise 10% to $43,514.	$58,587	$2,763 gap	Extra overhead pushes break-even above plan revenue.
Margin pressure	Variable expense rises to 32%.	$57,422	$1,598 gap	Travel, subcontracting, or software spend cuts the margin.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and variable expense hits 32%.	$58,698	$11,248 gap	That combination breaks the model fastest.

Is the gauge R&R study service ready to scale before you add staff, marketing, and equipment?

Founder checklist

Not yet if paid demand, fee mix, and cash are still unproven. The launch is ready when you can book 8 paid studies a month, hold the average study fee near $6,978, and carry the $907,500 launch cash load before adding more headcount or delivery capacity.

1Booked volume8 paid/mo

Confirm at least 8 paid studies a month before you scale, because that is the load that makes Month 6 break-even believable.

2Fixed load$6.85K/mo

Keep monthly fixed costs at $6,850 before adding space or admin work, since overhead hits even when bookings slow.

3Study fee$6.98K

Protect the weighted average study fee of about $6,978, because the mix shifts from full studies into lower-priced work.

4Delivery margin$5.09K

Keep variable delivery expense near 27% of revenue so each average study leaves about $5,094 after travel, subcontractor, software, and referral costs.

5Ad cost$2.2K

Check Year 1 customer acquisition cost of $2,200 against that $5,094 contribution per study, and keep the $45,000 first-year online budget tight, so paid demand buys margin.

6Launch cash$907.5K

Fund the $108,500 capex plan and hold the $799,000 minimum cash need through Month 6, then delay the Month 13 operations manager until billable hours can carry payroll.
