Running Cost 1
: Facility Lease
Lease: Fixed Compliance Cost
The ISO Certified Facility Lease sets a baseline fixed cost of $12,500 monthly, which you can't cut without risking production capability or regulatory standing. This space is non-negotiable because it supports the specialized manufacturing needed for these sensitive assistive devices.
Facility Inputs
This $12,500 covers the specialized footprint required for manufacturing and quality control, defintely meeting ISO certification standards. Since this is a fixed cost, it must be covered regardless of unit sales volume. Inputs needed are the lease agreement terms and the required square footage for clean room operations.
Monthly fixed cost: $12,500.
Covers ISO compliance space.
Supports required production setup.
Lease Management
Reducing this cost requires careful negotiation at renewal or scaling down space usage post-launch. Avoid moving to a non-certified space; that risk outweighs short-term savings. If production volume is low early on, negotiate a phased occupancy plan to manage initial cash burn.
Negotiate renewal terms early.
Phase occupancy if possible.
Do not sacrifice ISO standards.
Overhead Context
Compare this lease to other major fixed overhead. At $12,500, it's less than Key Personnel Wages ($70,417/month) but significantly higher than Product Liability Insurance ($4,200/month). Managing this major commitment dictates your minimum viable production run rate to cover overhead.
Running Cost 2
: Key Personnel Wages
2026 Core Payroll
Your 2026 payroll for 6 core FTEs totals $845,000 annually. This means you must budget $70,417 monthly for salaries alone, not counting employer taxes or benefits. This is a major fixed outlay required to scale production of your breath-controlled devices.
Cost Inputs
This $845,000 covers the salaries for your 6 essential hires needed in 2026 to run operations, likely including engineering and core sales roles. This figure is separate from Production Overhead Allocation, which is 115% of revenue monthly, and the $12,500 facility lease. You need to model benefits on top of this base payroll; defintely budget high for that burden.
Covers 6 essential roles.
Monthly salary base: $70,417.
Excludes employer burden costs.
Controlling Headcount
Managing this fixed cost requires strict hiring discipline. Avoid hiring ahead of validated demand, especially for roles not directly supporting immediate unit sales or regulatory compliance. If revenue projections slip, look first at freezing non-essential hiring or using contractors temporarily instead of adding permanent FTEs.
Hire based on milestones.
Use contractors initially.
Review benefit package structure.
True Labor Cost
Remember, this $70,417 monthly payroll expense is before you add employer payroll taxes, health insurance, or retirement matching. These benefits and taxes can easily add 25% to 35% more to the true operational cost of your 6 core employees.
Running Cost 3
: Product Liability Insurance
Insurance Reality Check
You need to budget for $4,200 monthly for Product Liability Insurance right now. This isn't optional; it's a fixed cost reflecting the serious risk associated with selling medical-grade assistive technology. Because your devices interface directly with users having severe motor impairments, underwriters price this coverage high. Don't miss this payment, or you risk shutting down before you sell unit one.
Cost Inputs
This policy shields the company from claims if a device malfunctions and causes user harm. You estimate this based on quotes from specialized medical device carriers, not unit volume. It sits as a crucial fixed overhead alongside your $12,500 facility lease and $9,000 in R&D costs. Honestly, this is non-negotiable overhead.
Fixed monthly expense: $4,200.
Covers bodily injury claims.
Required due to device classification.
Managing Premiums
You can't skimp on coverage for high-risk products, but you can manage the premium. Shop quotes annually between specialized brokers who understand the exposure of assistive tech. A clean claims history helps stabilize rates over time; avoid policy lapses defintely. This cost is locked in until you scale significantly.
Shop specialized brokers yearly.
Maintain zero claims history.
Review coverage limits every two years.
Impact on Break-Even
Since this is a fixed cost, its impact on your profitability scales inversely with sales volume. If you project $1.5 million in 2026 revenue, this insurance represents about 3.36% of that total top line. Focus on driving unit sales fast to dilute this fixed burden relative to your revenue.
Running Cost 4
: Sales Commissions
Commission Rate Impact
Sales commissions are a 50% variable cost tied directly to revenue, meaning half of every dollar earned goes out the door immediately. For 2026, this expense is projected to consume $386,250 of your top line. This high rate demands rigorous tracking against gross profit targets.
Calculating Commission Spend
This cost covers sales incentives, likely for direct reps or channel partners selling to hospitals and individuals. It is calculated simply as 50% of total revenue. If 2026 revenue hits the required level to generate $386,250 in commissions, your total revenue must be $772,500 ($386,250 / 0.50). This is a pure variable cost.
Input: Total Revenue Projection
Input: Commission Percentage (50%)
Output: Annual Commission Expense
Managing Variable Sales Cost
A 50% commission is steep for a medical device; review if this covers direct sales or institutional procurement agents. You must defintely structure tiers so that higher volume deals yield a slightly lower effective rate. Avoid paying commissions on setup fees or training services, which are often bundled.
Benchmark commission against industry standards.
Tie payout to net realized cash, not just bookings.
Negotiate lower rates for VA facility sales.
Margin Pressure Point
With commissions at 50% of revenue and Production Overhead Allocation at 115% of revenue (which sounds like a COGS issue needing review), your gross margin is immediately stressed. Every unit sold must have a high enough markup to cover both the 50% commission and the overhead before contributing to fixed costs like $845,000 in 2026 payroll.
Running Cost 5
: Production Overhead Allocation
Massive Overhead Drain
Your production overhead is currently unsustainable, totaling 115% of revenue monthly, or $74,031. This means you are losing money on every device sold before factoring in direct material costs. You must fix this cost structure now, not later.
Understanding COGS Overhead
This cost covers critical compliance and oversight within Cost of Goods Sold (COGS). It's calculated by taking your total projected monthly revenue and multiplying it by the 115% rate. The key inputs are your revenue forecast and the mandated 8% for Clean Room Sterilization and 8% for Factory Supervisor Allocation.
Revenue drives the total dollar amount.
Sterilization is tied to facility standards.
Supervisors ensure procedural adherence.
Cutting the 115% Burden
Since this overhead exceeds 100%, you need drastic action, not small tweaks. You can defintely start by challenging the necessity of the current sterilization schedule or negotiating fixed supervisor costs against actual production runs. You must raise prices immediately to cover this gap.
Negotiate sterilization frequency based on audit.
Shift supervisor costs to fixed overhead if possible.
Benchmark supervisor salaries against industry norms.
Focus on Component Savings
The two largest drivers are Clean Room Sterilization (8%) and Factory Supervisor Allocation (8%). If you manage to reduce the combined impact of these two items by just 20% of their current allocation, you save about $14,806 monthly from the total $74,031 overhead figure.
Running Cost 6
: R&D and IP Maintenance
R&D and IP Budget
Protecting your specialized sensor technology and ensuring future product iterations requires a fixed monthly spend of $9,000. This covers both material costs for ongoing development and necessary legal work to secure your intellectual property. If you skip this, competitors quickly catch up.
R&D Cost Breakdown
This $9,000 monthly spend is split between two critical areas for product longevity. You need $5,500 for Ongoing R&D Materials to test new sensor prototypes and refine existing designs. The remaining $3,500 covers Professional Legal and Patent Fees required to file and defend your unique breath-control technology.
$5,500 for materials.
$3,500 for legal fees.
Total fixed commitment: $9,000.
Managing IP Spend
You can't defintely skimp on patent defense, but material costs offer some flexibility. Negotiate bulk pricing for standard lab consumables used in R&D testing. Avoid filing provisional patents too early before core technology is locked down, which wastes filing fees.
Bulk buy standard R&D consumables.
Delay patent filings strategically.
Review legal retainer annually.
Fixed Cost Context
Compared to your $12,500 facility lease and $70,417 monthly payroll, this $9,000 is a relatively small fixed overhead. However, failing to fund this means your core differentiator-precision sensor technology-stagnates, making sales commissions unsustainable long-term.
Running Cost 7
: Marketing and Trade Shows
Fixed Marketing Spend
The monthly budget for marketing and trade shows is set at a fixed $8,000. This spend is specifically allocated to generate institutional sales volume, which is key for scaling device distribution through hospitals and Veterans Affairs facilities.
Budget Inputs
This $8,000 monthly line item covers all outreach efforts aimed at large buyers, including exhibiting fees and travel for trade shows. It's a fixed operating expense, meaning it doesn't scale with unit sales, unlike the 50% sales commissions. You need quotes for booth space and travel logistics to finalize this estimate.
Covers institutional outreach costs.
Fixed, not based on unit sales.
Requires travel and booth planning.
Managing Outreach
Since this is fixed, focus on maximizing return on investment (ROI) from each event. Don't spread the budget too thin across dozens of small events. Prioritize shows where rehabilitation centers and Veterans Affairs facilities gather. If onboarding takes 14+ days, churn risk rises because initial setup support is crucial for these complex devices.
Sales Volume Link
Hitting institutional targets is critical because fixed costs like this $8,000 marketing spend, plus the $12,500 facility lease, require high-volume sales to cover overhead. You're defintely aiming for large contracts, not just individual consumer sales.
Operating expenses and overhead typically range from $230,000-$240,000 per month in 2026, excluding direct unit COGS, with fixed costs totaling $37,700 monthly
Sales Commissions are the largest variable OpEx at 50% of revenue, followed by Shipping and Logistics at 35%
The model shows a minimum cash requirement of $1,113,000 in January 2026 to manage initial capital expenditures and working capital needs
Core team payroll for 6 FTEs starts at $845,000 annually in 2026, increasing as the team scales to meet demand
The financial model projects an immediate breakeven date of January 2026, requiring 1 month to achieve profitability
Production overhead, including regulatory audits and facility utilities, defintely accounts for 115% of projected annual revenue
