Which expenses stay fixed and which move with sales in a force plate testing business?

Cost classification

Break-even is reliable only when monthly overhead is kept separate from sales-linked spend. In this model, Month 1 break-even depends on recurring operating costs, not the $495,000 launch equipment and build-out spend.

Expense	Cost	Break-Even Treatment	Common Mistake
Lab Facility Rent	Fixed	Include $12,500 per month in fixed overhead from Month 1 through Month 60.	Treating rent as tied to testing volume when it’s due even in a slow month.
Professional Liability Insurance	Fixed	Include $1,800 per month in fixed overhead for the full model period.	Leaving insurance out of break-even because it doesn’t attach to a single session.
Utilities and High Speed Internet	Fixed	Include $950 per month as baseline overhead for lab operations.	Modeling utilities as fully variable when the base service remains active regardless of sessions.
Operating Wages	Semi-fixed	Model salaries as capacity steps, rising from $500,000 in the first year to $1,010,000 in the mature year.	Spreading wages as a percentage of revenue instead of adding headcount when capacity expands.
SaaS Platform Subscriptions	Semi-variable	Start with the $2,200 monthly base, then add usage or seat increases only when the plan changes.	Locking the subscription as fixed forever even as staff count and data workflows grow.
Cloud Data Processing Fees	Variable	Apply as a revenue-linked expense, falling from 4.5% in the first year to 3.5% in the mature year.	Putting processing fees in fixed overhead and overstating margin at higher session volume.
Disposable Sensor Consumables	Variable	Apply per testing volume, using 2.5% of revenue in the first year and 1.8% in the mature year.	Forgetting that consumables rise with each assessment, even when unit rates improve.
Digital Marketing and Lead Gen	Variable	Model as sales-linked spend, dropping from 8.5% of revenue in the first year to 6.5% in the mature year.	Treating lead generation as a flat monthly line while expecting revenue to scale.

How does break-even change across lean, base, and full utilization for force plate testing?

Scenario table

Higher volume spreads fixed lab and staff cost across more tests, so break-even stays close while the profit cushion widens fast. Base is the first setup that looks comfortably scaled.

Planning assumptions only; actual results will move with mix, utilization, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean lab launch	$100K	$19.5K	$52.0K	80.5%	$28.5K	Demand is proven, but the cushion is thin.
Base recurring package scale	$459.2K	$79.0K	$73.3K	82.8%	$306.9K	This is the first level with a solid cushion.
Full utilization network	$1.11M	$166.5K	$87.4K	85.0%	$856.0K	Strong cushion, but only if staffing and use stay tight.

What breaks the break-even plan if bookings slip or costs run hot?

Stress test

The base plan has a solid cushion, but it narrows fast if bookings soften or costs creep up. Discounts, low team bookings, travel overages, and slower referrals are the main break-even risks.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base case.	$775K	$225K cushion	Healthy cushion if volume holds.
Revenue shortfall	Monthly bookings fall 20% to $800K.	$775K	$20K cushion	Soft referrals or discounts can wipe out the buffer fast.
Fixed-cost increase	Fixed costs rise 10% to about $687K a month.	$853K	$147K cushion	Rent, payroll, and overhead creep move break-even fast.
Margin pressure	Variable expense rate rises 5 points to 24.5%, cutting margin to 75.5%.	$827K	$173K cushion	Small fee leaks hit margin before you feel them in cash.
Combined pressure	Revenue falls to $800K, fixed costs rise to $687K, and variable expense rate hits 24.5%.	$909K	$83K gap	This is the fail case if bookings stay soft and costs run hot.

Can you prove the booking pipeline and cash cushion before you lock the lab lease and buy the full force plate stack?

Founder checklist

Before you lock the lab, hire the team, or buy the full equipment stack, test whether Year 1 demand, pricing, and utilization can cover fixed costs. If the booking mix does not hold up on paper and in pipeline data, delay the commitment.

1Pipeline depth361 sessions/mo

Confirm the booking pipeline can support about 361 mixed sessions a month before you sign space, because that is the demand base the model needs.

2Price mix$125-$350

Test the Year 1 rate card at $125 junior, $175 analyst, $250 sports scientist, $275 rehab specialist, and $350 senior biomechanist, so the mix still clears when demand shifts.

3Fixed load$20.75K/mo

Keep monthly fixed spend at $20,750 or below, because rent, insurance, software, utilities, maintenance, office, and bookkeeping hit before volume can save you.

4Load ramp35%-55% / 4.0%

Prove the team can stay in the Year 1 utilization band of 35% to 55% and keep travel near the 4.0% line, or on-site delivery will eat margin fast.

5Unit margin80.5% CM

Here’s the quick math: cloud data processing and consumables total 7.0%, and digital marketing plus travel total 12.5%, leaving an 80.5% contribution margin before payroll and rent.

6Cash buffer$661K / $495K

Delay noncritical capex where you can, because launch capex totals $495K and minimum cash dips to $661K in Month 5, so the opening build needs a deep reserve.
