Want the six drivers that move owner income most?
1
Unit Sales
7.3K-45.7K
Total units rise from 7,300 in Year 1 to 45,700 in Year 5, so volume is the main cash engine.
2
Price Mix
$65-$935
The mix runs from $65 replacement parts to $935 advanced arms, so more high-end sales lift revenue fast.
3
Gross Margin
83%-84%
Direct product cost stays low versus price, which keeps gross margin near 83%-84% before fixed costs.
4
Channel Costs
17%-12%
Commissions, ads, and shipping fall from 17% of sales to 12%, so channel discipline protects take-home.
5
Overhead Load
$717K
About $302K of annual fixed overhead plus $415K of listed wages hits cash before growth does, so staffing must stay lean.
6
Inventory Cash
High
Replacement parts, returns, and stockouts can trap cash in stock, and the model does not give a reserve rate.
How much revenue does an IV practice arm business need to pay the owner?
For IV Practice Arm Training Model Sales, the owner can pay themselves only after revenue clears the fixed-cost stack. The target-pay math says you need about $809k to fund a $145k owner salary, and about $880k if reinvestment stays in the plan, after listed COGS and variable costs plus the $110k non-owner salary. That compares with the provided first-year revenue forecast of $141M, so the real swing factor is margin, not demand.
Pay threshold
About $809k funds $145k owner pay.
$880k covers reinvestment, too.
$100k owner pay needs less revenue.
Fixed overhead still has to be covered.
What changes it
17% variable costs cut cash left.
Higher gross margin lifts owner pay fast.
Fixed overhead shifts break-even the most.
Reinvestment lowers near-term owner income.

Can an IV practice arm business be owner-operated?
IV Practice Arm Training Model Sales can be owner-operated early for sales coordination, sourcing, quote follow-up, customer service, and inventory planning. But it is not a true one-person operation under the provided model: the plan already includes a $145k CEO and operations lead, a $110k material scientist, and $3,024k in annual fixed overhead. With 7,300 units in year 1 and 45,700 in a mature year, solo labor can save cash at the start, but scaling needs systems and help.

IV Practice Arm Training Model Sales Core Six Income Drivers
Unit Sales Volume
Unit Sales Volume
This driver is the number of arms, kits, packs, and trainers sold. The first-year plan is 7,300 units: 1,200 Basic Arms, 400 Advanced Arms, 3,000 replacement skin kits, 2,500 vein packs, and 200 pediatric trainers, producing $141M revenue. At maturity, volume reaches 45,700 units and $827M revenue, so more units spread fixed overhead and lift owner profit.
The cash risk is timing. Nursing programs, emergency medical services academies, phlebotomy schools, and simulation labs buy on budget cycles, so slow purchase orders can push revenue into later months. If stockouts or fulfillment bottlenecks hit, sales drop even when demand exists. That delays cash, keeps overhead in place, and can shrink owner pay before the income statement catches up.
Track Volume by SKU
Measure units by product line, buyer type, and month. The quick math is units sold x price = revenue, but only if inventory and shipping can keep up. Watch backlog, fill rate, and quote-to-PO time. A large school order can lift volume fast, but a weak process turns that win into delayed cash and uneven profit.
Focus on the few controls that move volume:
Forecast around school buying seasons
Hold safety stock on fast movers
Separate slow and fast product lines
Track lost sales from stockouts
Measure purchase-order cycle time
When units slip, owner income slips too, because fixed overhead and payroll still keep running.
Landed COGS and Gross Margin
Landed COGS and Gross Margin
When landed COGS rises, each arm simulator leaves less gross profit for payroll, R&D, and owner pay. Keep product cost separate from operating expenses: unit COGS covers silicone, tubing, frames, labor, packaging, electronic modules, skin sheets, valves, and pediatric mold components; factory overhead adds insurance, depreciation, quality control, utilities, and waste disposal.
The model shows $2.768M of COGS on $141M first-year revenue, with gross profit stated at about $113M. Mature-year COGS are $153M on $827M revenue. One line sums it up: bad quality turns profit into warranty cash drain.
Track cost per usable unit
Build landed COGS from units sold, material yield, labor hours, scrap, and factory overhead. Track cost per model by product line, then compare it to selling price and channel mix. If replacement skins or vein packs fail early, the margin loss shows up twice: lower gross profit and more cash tied up in rework.
Measure scrap, rework, and returns
Separate factory cost from opex
Watch replacement-driven cash leakage
If quality control slips, the accounting margin can look fine while cash falls because you are remaking parts, shipping replacements, and using more labor than planned. That is the number to protect if owner draws matter.
Owner Role and Operating Overhead
Owner Pay and Overhead
Owner labor can lower cash burn, but it is not scalable profit. This model already includes $145k for a CEO and operations lead, $110k for a material scientist, and $252k/month in fixed overhead, or $3,024k/year, across rent, lab supplies, insurance, software, trade shows, utilities, and maintenance.
That cost stack comes before owner distributions. If the owner works in the business, book that pay separately so operating profit stays clean; otherwise, you can mistake unpaid labor for real margin. The business only supports take-home income after gross profit covers those fixed costs and any added fulfillment or sales support.
Separate Pay From Profit
Track gross profit, fixed overhead, and owner pay every month. The key test is simple: can the model cover $252k in monthly overhead before any distribution? If not, the owner is subsidizing the business with labor or cash, not drawing true profit.
Record owner hours and salary.
Split overhead by cost bucket.
Watch fulfillment error rates.
Test sales support costs monthly.
Protect quality before cutting staff.
Outsourcing fulfillment or adding sales support may raise overhead, but it can protect delivery quality and repeat orders. If those costs reduce returns, delays, or lost school accounts, they can lift owner income later even when near-term cash burn goes up.
Average Selling Price and Product Mix
Average Selling Price and Mix
When the mix shifts toward $850 Advanced Arms instead of $65 vein packs, revenue per order rises fast, and so does contribution profit — the cash left after variable costs. First-year prices run from $65 to $850; mature-year prices run from $75 to $935. One large school order can boost volume but lower unit price, so model institutional pricing separately.
Repeat items like replacement kits and vein packs can create repeat orders, while bundled kits can lift AOV (average order value) if the discount stays below the margin you give up. The owner’s take-home income improves when high-price units carry the mix and discounts stay controlled. If bundle pricing cuts contribution per order, the extra sales won’t translate into more cash for pay or draws.
Track Price by SKU
Measure units sold by SKU, discount rate, repeat purchase rate, and contribution per order. Here’s the quick math: AOV = total order revenue ÷ orders. Compare school orders, hospital orders, and replacement-kit orders on their own so one big contract does not hide weak pricing.
Set a price floor by channel.
Test bundle discounts on kits first.
Watch contribution, not just revenue.
Forecast institutional orders separately.
Raise prices on higher-end arm models.
Push mix toward the higher-priced arm models, then use replacement kits and vein packs to drive repeat sales. If a bundle lifts revenue but drops margin, it hurts owner income even when orders look strong. Keep the pricing file clean by SKU and channel, and update it before each buying season.
Inventory Cash Flow, Returns, and Stockouts
Inventory Cash Flow and Stockouts
Profit on paper is not the same as cash in your pocket. This model sells physical units, replacement parts, packaging, quality control, and shipping, so cash can sit in inventory before revenue is collected. Since no separate inventory reserve, return rate, warranty reserve, or reorder point is provided, those need editable assumptions. Owner income should be paid after working capital needs.
Here’s the quick math: if money is tied up in slow-moving pediatric trainers or extra replacement parts, it is not available for distributions. And if stock runs out during school buying cycles, sales shift later or disappear. With 7,300 planned first-year units, inventory timing is a real cash driver, not just an ops detail.
Track stock before it hits cash
Measure each SKU by on-hand units, inbound units, sold units, damaged units, and days of inventory on hand. Set a reorder point from lead time plus weekly unit sales, then add a reserve for returns and warranty replacements because none is modeled here. One missed replenishment can push revenue out of the current period.
Watch school buying windows.
Flag slow-moving SKUs fast.
Separate damaged from sold units.
Keep cash for replacements.
Use stockout alerts before a purchase order is late, not after. If demand is ready and the unit is out of stock, the business loses margin now and the owner loses draw later.
Customer Acquisition and Sales Channels
Sales Channel Payback
Customer acquisition here is not about traffic; it’s about the net cash left after commissions, digital spend, and shipping. In year one, those variable costs total 17% of revenue (5% sales commissions, 8% digital marketing and lead generation, 4% shipping and logistics), so every $100 in sales leaves $83 before fixed overhead and owner pay.
In a mature year, variable costs fall to 12% as digital marketing drops to 4% and logistics to 3%, so the same $100 leaves $88. That gap matters because marketplace commissions, distributor discounts, paid search, quote follow-up, and purchase-order delays can turn booked demand into slow cash.
Track Channel Payback Fast
Measure each channel by contribution margin, not clicks. A $10k ad test only works if it creates enough gross profit to pay back quickly, which means you need channel-level sales, commission, shipping, and lead-cost data before you scale spend.
Track revenue by channel.
Track commission and discount rates.
Track quote-to-order time.
Track shipping cost per unit.
Watch cash timing too. If purchase orders drag or quote follow-up slips, reported sales can look fine while owner cash stays trapped. Tie spend to the channels that convert fastest and keep the 17% first-year variable load from eating the payback on each deal.
