General and Administrative (G&A) payroll and office costs are estimated at $35,000 monthly.
This covers core administrative staff, software subscriptions, and basic office space; it’s your baseline cost.
This $35k must be covered before any profit shows, regardless of volume.
If onboarding takes too long, this fixed cost burns cash defintely faster.
Variable Cost Drivers
Variable Cost of Goods Sold (COGS) per screening is estimated at $45.
This $45 covers practitioner fees, supplies, and travel reimbursement per visit.
At a $100 average fee, your contribution margin is 55% ($55 per service).
You need about 637 screenings monthly just to cover the $35k fixed overhead.
Which recurring cost categories will consume the largest share of early revenue?
For Corporate Health Screening, variable costs tied to service delivery—specifically practitioner time and supplies—will consume the largest share of early revenue, eclipsing fixed overhead until significant volume is reached. Understanding this cost structure is key to assessing viability, and you can read more about the underlying economics here: Is Corporate Health Screening Profitable? Since revenue is a per-treatment fee, every screening directly incurs a high cost of goods sold (COGS) component.
Variable Cost Drivers
Practitioner compensation per screening is the primary variable expense.
Supplies, like testing kits and disposables, scale one-to-one with volume.
High variable costs mean contribution margin per treatment must be strong.
If practitioner utilization is low, revenue won't cover the fixed base salary.
Fixed Overhead Exposure
Fixed overhead includes salaries for sales/admin and central office rent.
These costs must be covered by the gross profit generated from screenings.
Scaling requires adding more practitioners, which shifts costs back to variable.
If onboarding takes 14+ days, churn risk rises before fixed costs are absorbed.
How much working capital is required to cover costs before reaching consistent profitability?
To cover initial operational burn before the Corporate Health Screening service hits consistent profit, you must secure a minimum working capital reserve of $848,000, targeting a full payback period of just 4 months; this aggressive timeline requires tight control over practitioner utilization, which is critical when mapping out your strategy, as detailed in What Are The Key Steps To Develop A Business Plan For Your Corporate Health Screening Service?
Runway Requirement
You've got to have $848,000 secured for initial operating expenses.
The target payback period is aggressively set at 4 months.
This cash covers upfront practitioner onboarding and initial sales cycles.
If onboarding takes defintely longer than 14 days, churn risk rises.
Hitting Payback Velocity
Focus sales efforts on dense zip codes first for efficiency.
Ensure average contract value (ACV) hits $50,000 minimum.
Every day past month four increases capital strain significantly.
How will we cover fixed costs if service volume falls below 50% of the forecast?
If service volume for Corporate Health Screening defintely drops below 50% of the forecast, immediate action requires cutting non-essential operating expenses to protect cash flow until volume recovers.
Immediate Cost Levers
Pause all non-essential marketing spend immediately.
Delay hiring any administrative or non-clinical support staff.
Review all supplier contracts for 30-day cancellation clauses.
If fixed overhead is $30,000 monthly, cutting $5,000 in discretionary spend buys you almost two extra weeks of runway.
Protecting Practitioner Capacity
Analyze practitioner utilization; if below 65%, halt new practitioner onboarding.
Shift salaried practitioners to an on-call, per-screening pay structure temporarily.
Audit current fixed costs to see if equipment leases can be renegotiated down.
The initial fixed monthly running cost required to sustain corporate health screening operations is approximately $30,000, driven primarily by core payroll and rent.
Due to strong service pricing and efficient delivery, the business model projects a rapid path to profitability, reaching break-even status in just one month.
Founders must secure a significant working capital buffer of $848,000 to cover initial capital expenditures and operational needs during the first few months.
Variable costs, specifically medical supplies (80% of revenue) and practitioner hourly wages (70% of revenue), represent the largest share of early revenue consumption requiring tight management.
Running Cost 1
: Core Staff Payroll
Core Fixed Payroll
Your initial fixed payroll commitment for the leadership team—CEO, Operations Manager, and Administrative Assistant—is substantial. This core staff expense hits about $23,333 per month right out of the gate. This cost must be covered before you even invoice your first client screening.
Staff Cost Inputs
This $23,333 estimate covers the fully loaded monthly cost for your three essential, non-billable roles. You need finalized salary agreements, plus estimates for payroll taxes and benefits, which often add 20% to 30% above base salary. This fixed overhead must be covered by the revenue generated by your practitioners.
CEO salary component
Operations Manager salary component
Administrative Assistant salary component
Managing Fixed Staff Burn
You can't cut these roles, but you can definitely delay hiring or adjust compensation structures. Founders often take minimal salary initially, offsetting the cash burn with equity grants. If the Admin Assistant role can be outsourced to a fractional service for the first six months, you might save $4,000 monthly.
Phase hiring based on revenue milestones.
Use equity to lower initial cash salaries.
Consider fractional support early on.
Payroll and Break-Even
Since this payroll is fixed, your break-even analysis hinges on covering this $23.3k before variable costs hit. If you hire the Operations Manager six months later than planned, that's $140,000 in saved cash burn, which is a massive advantage for a service business like this.
Running Cost 2
: Medical Supplies & Consumables
Supply Cost Warning
Medical supplies are your biggest cost driver, eating up 80% of revenue by 2026. This high ratio means scaling revenue without deeply controlling unit economics will crush margins fast, especially since other variable costs are high too.
What Supplies Cost
These variable costs cover every disposable item needed for a screening, like test kits and gauze. The 80% projection for 2026 is based on detailed quotes for all necessary materials per procedure. It dwarfs fixed costs like the $3,500 rent.
Covers all screening materials.
Disposables are included here.
Calculated as 80% of gross revenue.
Cut Supply Drag
You must negotiate volume discounts immediately, even if 2026 seems far off. If you can push this down to 70%, you free up 10% margin, which is huge when practitioner wages are already 70%. Don't wait for volume to hit before seeking better supplier terms, defintely start now.
Benchmark supplier pricing now.
Seek volume tier discounts early.
Avoid rush shipping fees.
Margin Check
With supplies at 80% and practitioner wages at 70%, your gross margin is potentially negative before accounting for 30% technology platform fees. You need to re-evaluate the per-treatment fee structure or drastically cut supply costs, because right now, every job loses money before fixed overhead.
Running Cost 3
: Practitioner Hourly Wages
Labor Cost Leverage
Practitioner wages are your single biggest lever for profitability, hitting 70% of revenue in 2026. Because this covers Registered Nurses, Phlebotomists, and Medical Assistants, managing scheduling efficiency directly determines gross margin. If you miss revenue targets, this cost crushes margins fast.
Inputs for Wage Spend
This $70\text{ cents on the dollar}$ expense pays your clinical team—Registered Nurses, Phlebotomists, and Medical Assistants—by the hour for on-site screenings. To model this accurately, you need the average blended hourly rate (including payroll burden) multiplied by the total scheduled service hours required to meet projected screening volume. This is your primary variable cost driver.
Need blended hourly rate.
Multiply by total service hours.
Must align with volume targets.
Controlling Clinical Time
Controlling 70% of revenue requires tight scheduling against demand. Avoid paying premium overtime for low-volume days or letting staff wait between client sites. Optimize practitioner utilization by stacking appointments efficiently within the client's workflow window. If onboarding takes 14+ days, churn risk rises.
Schedule tightly to volume.
Minimize non-billable travel time.
Negotiate favorable per-visit rates.
Margin Reality Check
Since this labor cost is 70% of revenue, your contribution margin before other variables (like supplies at 80% of revenue) is razor thin until you achieve massive scale or significantly raise per-treatment fees. Defintely watch utilization daily.
Running Cost 4
: Office Space Rent
Fixed Rent Baseline
Office rent sets your baseline overhead before payroll even hits. This fixed expense is $3,500 per month for your administrative and operational headquarters. You need this space secured to manage compliance and scheduling for the mobile screening teams. It’s a non-negotiable cost today.
Rent Inputs
This $3,500 covers the physical base for your corporate health screening operations. Inputs needed are simple: one signed lease agreement for the HQ space, though the data only confirms the monthly rate. This rent is a critical fixed cost that must be covered regardless of screening volume. Honestly, it’s one of the easier numbers to pin down.
Fixed cost: $3,500 monthly
Covers HQ administrative needs
Needed defintely before first client visit
Managing HQ Costs
Since rent is fixed, optimization means minimizing the footprint or duration. Avoid signing a multi-year lease immediately; look for flexible, short-term agreements initially. If you combine this with your $1,750 G&A overhead, you have $5,250 in non-payroll fixed costs to cover before revenue starts flowing. Don't over-lease early on.
Prioritize flexible terms
Watch combined fixed overhead
Avoid large upfront deposits
Total Fixed Base
Your total fixed operating expense, excluding payroll, is $5,250 per month ($3,500 rent plus $1,750 G&A). This amount must be covered by your contribution margin before you start paying practitioners or buying supplies. Keep this baseline in mind when setting volume targets for the first six months.
Running Cost 5
: Insurance and Compliance Software
Regulatory Baseline
Regulatory adherence for this health screening operation requires a fixed monthly spend of $1,250. This covers mandatory General Liability Insurance and necessary HIPAA Compliance Software to operate legally within the US healthcare space.
Fixed Compliance Inputs
This $1,250 is a fixed monthly commitment necessary before seeing the first client. General Liability Insurance costs $800/month, protecting against potential operational mishaps. HIPAA Compliance Software, essential for handling protected health information (PHI), adds another $450/month.
General Liability: $800
HIPAA Software: $450
Managing Regulatory Spend
You can’t skimp on these, but you can shop around for better rates. For General Liability, get three quotes; savings might hit 10% to 15% if your initial risk assessment is favorable. Always verify the HIPAA software supports necessary audit trails, as cheap solutions often lack critical reporting features.
Shop GL quotes aggressively.
Audit HIPAA feature set first.
Avoid annual prepayment risk initially.
Overhead Context
When mapping fixed costs, remember this $1,250 sits alongside $1,750 in G&A and $3,500 in rent, totaling $6,950 in baseline overhead before payroll or supplies even start. That’s a lot of screenings just to cover the lights.
Running Cost 6
: Technology Platform Fees
Tech Fee Weight
Platform fees for essential software like scheduling and EHR eat up 30% of revenue in 2026. This high variable cost demands aggressive volume growth just to cover the tech stack before paying for practitioners or supplies. You need to know your break-even volume based on this substantial software drag.
Cost Drivers
This 30% expense covers critical functions: appointment scheduling, regulatory reporting, and maintaining patient Electronic Health Records (EHR). To estimate the dollar amount, multiply projected monthly revenue by 0.30. Since it scales with every screening dollar earned, it’s a major margin constraint if revenue targets aren't hit.
Optimization Tactics
Since this is tied to revenue, you can’t just cut it; you must negotiate or switch platforms. Look for tiered pricing based on user count, not gross revenue. If you onboard 100 clients, check if volume discounts kick in. Avoid paying for unused modules in your EHR suite, honestly.
Margin Check
Considering other major variable costs—supplies at 80% and practitioner wages at 70%—this 30% tech fee is the easiest lever to pull if you can switch vendors. High variable costs mean your contribution margin will be very slim, so every percentage point saved here is crucial for profitability.
Running Cost 7
: Administrative Overhead (G&A)
Fixed Overhead Snapshot
Your fixed General and Administrative (G&A) costs are set at $1,750 per month. This baseline covers essential non-operational expenses like compliance, basic IT, and utilities. Keeping this number low is crucial since these costs hit the bottom line regardless of screening volume. Honestly, this is the easy part to budget.
G&A Cost Breakdown
Fixed G&A is predictable overhead necessary to operate legally and stay online. You calculate this by summing mandatory monthly service contracts. For example, legal services are budgeted at $1,200 monthly. This estimate hides potential increases in compliance software costs down the defintely road.
Utilities: $300/month.
Accounting/Legal: $1,200/month.
Website upkeep: $250/month.
Managing Overhead
Since these are fixed, they don't scale with revenue, which is good once volume picks up. To reduce this, review your accounting retainer annually; often, smaller firms can negotiate better rates than established ones. Don't defer website costs; cheap maintenance often leads to expensive emergency fixes later.
Audit legal retainers yearly.
Bundle utility services if possible.
Ensure website costs are competitive.
Fixed Cost Impact
Every dollar of this $1,750 fixed G&A must be covered before you make a dime of profit. Because it’s fixed, scaling revenue spreads this cost thinner, improving margins quickly once you pass break-even. This is why managing variable costs, like the 70% practitioner wages, is the primary lever for profitability.
Initial fixed running costs are approximately $30,000 per month, primarily driven by core payroll and rent Variable costs add another 200% of revenue, but high volume allows for a rapid break-even in 1 month
Core staff payroll and fixed G&A overhead, totaling around $30,000 monthly, represent the largest fixed expense Variable COGS (supplies and practitioner wages) are 150% of revenue, requiring defintely tight management as volume scales
