Which fake blood supply expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if each expense behaves the right way in the model. Put unit materials and revenue-linked fees against contribution, and keep stable monthly overhead in fixed costs.

Expense	Cost	Break-Even Treatment	Common Mistake
Cosmetic Grade Pigments	Variable	Treat the $1.20 per unit as direct unit expense that lowers contribution on every Arterial Spray sale.	Parking materials in overhead, which overstates unit margin.
Custom Glass Bottling	Variable	Deduct the $1.50 per unit before calculating contribution margin, since bottles scale with units produced.	Treating packaging as fixed because it is bought in bulk.
Quality Control Testing	Variable	Model at 0.8% of revenue, so testing expense rises as sales volume and batch activity rise.	Using one flat lab budget even when revenue doubles.
Shipping and Logistics Hub Fees	Variable	Use 5.0% of first-year revenue and the model’s lower rates in later years to reduce contribution.	Leaving fulfillment below the break-even line.
Manufacturing Facility Lease	Fixed	Include $12,500 per month in fixed overhead for the relevant planning range.	Spreading rent per bottle and hiding the monthly cash hurdle.
Product Liability Insurance	Fixed	Include $2,200 per month as fixed overhead because the model treats it as a recurring monthly charge.	Assuming all insurance moves with sales volume.
Warehouse and Bottling Staff	Semi-fixed	Treat labor as capacity-step expense, rising from 2.0 FTE in the first year to 7.0 FTE by the fifth year.	Calling all labor variable and missing hiring thresholds.

How does break-even shift from lean proof-of-demand to full production scale?

Scenario table

Break-even rises as this blood-effects shop adds staff and trade-show overhead, but margin also widens as the mix shifts to higher-priced products. Lean proves demand, base is the clean repeat-account step, and full only works with steady capacity use.

Planning-case figures only; actual break-even will move with mix, pricing, and staffing timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean proof-of-demand case	$135.9k	$38.9k	$59.1k	71.4%	$31.9k	Monthly break-even is about $82.8k, so this clears it with the thinnest cushion.
Base repeat-account case	$263.9k	$70.7k	$75.5k	73.2%	$105.2k	Monthly break-even is about $103.1k, and this is the cleanest scale point for repeat film and theater orders.
Full mature-capacity case	$538.1k	$134.0k	$92.5k	75.1%	$279.2k	Monthly break-even is about $123.1k, so this works only if capacity stays filled.

What breaks the break-even plan for theatrical blood effects supply?

Stress test

The base plan clears break-even, but it gets tight fast if wholesale discounting, rush shipping, supplier price hikes, or higher rent and insurance hit before repeat orders are stable. Under the combined downside, the cushion drops to about $175k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$828k	$531k cushion	Base case clears break-even with room.
Revenue shortfall	Monthly revenue falls 15% to about $1,155k.	$828k	$327k cushion	Sales slippage cuts the cushion fast.
Fixed-cost pressure	Fixed monthly costs rise 10% to about $650k.	$911k	$448k cushion	Lease, insurance, or staffing creep tightens coverage.
Margin pressure	Variable expenses rise 5 percentage points and cut contribution margin to 66.4%.	$891k	$468k cushion	Supplier or freight inflation raises the sales bar.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and contribution margin drops to 66.4%.	$980k	$175k cushion	One more shock could flip profit to loss.

What should the founder verify before signing the lease and buying the first production line?

Founder checklist

Test demand, fixed costs, and cash together before you commit. This model needs about $828K a month to break even, so the first orders, supplier pricing, and launch capacity have to line up fast.

1Demand floor$828K/mo

Verify signed demand can support the monthly break-even load before you lock the lease or inventory buys.

2Supplier quotes9 inputs

Get quotes for pigments, thickeners, preservatives, bottles, jars, caps, labels, cartons, and specialty inputs so pricing and margin are real, not guessed.

3Output capacity35,000 units

Confirm the first-year line can produce 35,000 units across five product formats without bottlenecks in mixing, bottling, or packout.

4Storage fit$22K unit

Test storage needs before you commit to the $22,000 climate-controlled unit, because the wrong space ties up cash before sales catch up.

5Fixed load$20.45K/mo

Check that lease, the $2,200 liability policy, service, software, trade show, and security costs still fit inside monthly gross contribution.

6Cash ramp$1.065M / $464K / $246.5K

Keep enough cash for the Month 2 minimum need, hire only when gross contribution can cover the $464K Year 1 payroll base, and phase the $246.5K capex plan.
