Which mobile testing expenses stay fixed, and which move with sales?

Cost classification

Break-even is only reliable when test-linked costs move with revenue and monthly overhead stays fixed. In the first operating year, the big cleanup is keeping consumables, travel, booking fees, and commissions out of overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Medical Test Kits & PPE	Variable	Model at 10.0% of first-year revenue.	Treating consumables as fixed overhead.
Practitioner Travel Reimbursement	Variable	Model at 3.0% of first-year revenue.	Burying route miles inside general overhead.
Booking Platform Fees	Variable	Model at 2.0% of revenue tied to bookings.	Combining booking fees with platform subscriptions.
Marketing & Sales Commissions	Variable	Model at 4.0% of revenue.	Mixing commissions with base sales salaries.
Office Rent	Fixed	Use $3,500 per month in break-even overhead.	Allocating rent per test.
Technology Platform Subscriptions	Fixed	Use $1,200 per month as fixed overhead.	Confusing subscriptions with booking fees.
Vehicle Fleet Fixed Costs	Fixed	Use $2,000 per month, separate from travel reimbursement.	Blending fleet overhead with trip-level travel.
CEO, Operations Manager, and Sales Manager Wages	Semi-fixed	Use about $23,333 per month in first-year staffing overhead.	Missing staff step-ups after the first year.

How does break-even shift from a lean launch to a full route network?

Scenario table

Dense routes lower variable expense from 19.0% in the lean case to 17.2% in the full case, so the break-even cushion widens even as fixed staffing rises. The base case is the cleanest mid-point for contract traction.

Planning assumptions only; actual break-even will move with route density, staffing mix, and contract mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch validation	$938k	$178k	$323k	81.0%	$437k	About $540k of cushion above break-even.
Base contract traction	$3,000k	$543k	$435k	81.9%	$2,022k	Fixed costs are covered well before scale peaks.
Full route coverage	$6,831k	$1,176k	$540k	82.8%	$5,115k	Strongest cushion, with the lowest break-even pressure.

What could push mobile COVID testing past break-even?

Stress test

Year 1 has a wide cushion, but it shrinks fast if bookings soften, fixed staff costs rise, or kit and travel costs creep up. The main risk is hiring ahead of confirmed demand.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$399k	$540k cushion	Year 1 revenue stays well above break-even.
Revenue shortfall	Year 1 revenue drops from $938k to $399k.	$399k	$0 gap	The plan lands right on break-even, so any softer bookings turn it negative.
Fixed-cost pressure	Year 1 fixed costs rise from $323k to $435k.	$538k	$400k cushion	Higher overhead trims about $140k of room.
Margin pressure	Variable expense rises 1.0 percentage point, cutting margin to 80.0%.	$404k	$534k cushion	Small kit or fee creep still eats into the cushion.
Combined pressure	Year 2 fixed costs and 2.0% variable expense both hit.	$544k	$394k cushion	Bookings and cost creep together still clear break-even, but with less room.

What should you verify before signing the lease and buying vehicles for mobile COVID testing?

Founder checklist

Don’t lock in fixed costs until paid demand, route density, and cash all clear the break-even bar. For this model, that means proving about 384 tests a month at roughly $104 per test, while covering the $385K startup spend and the Month 2 $739K cash need.

1Paid demand384 tests/mo

Verify booked, paid volume can reach about 384 tests a month before you commit to the fleet and lease.

2Route densityHigh-density zones

Map service areas first so travel miles stay tight enough to support break-even instead of bleeding time and fuel.

3Unit margin81% CM

Check that kits, PPE, travel reimbursement, booking fees, and sales commissions stay near plan so gross margin holds at 81%.

4Staffing ramp8 core staff

Schedule 3 Registered Nurses, 2 Medical Assistants, 1 Phlebotomist, 1 Paramedic, and 1 Lab Technician around route demand, not around headcount goals.

5Cash cushion$739K

Hold enough cash for the $385K startup spend and the Month 2 minimum cash need of $739K before you expand.

6Fixed load$435K load

Delay Year 2 support hires until contracts can carry the $435K fixed-cost load, and track booking flow, cancellations, route time, and gross margin every week.
