Cost classification

Break-even is only reliable when fixed burn, unit costs, and revenue-linked fees are separated. Here, payroll, utilities, and quality controls can distort contribution margin if treated as purely volume-based.

Expense	Cost	Break-Even Treatment	Common Mistake
Facility Rent	Fixed	Include $12,000 per month in fixed overhead before calculating unit break-even.	Spreading rent across units too early and hiding the monthly cash floor.
Insurance	Fixed	Include $1,500 per month as fixed overhead across the full planning range.	Modeling insurance as a per-unit charge instead of required operating coverage.
Utilities	Semi-variable	Use $2,500 per month as the base, plus the 0.1% utilities allocation tied to revenue.	Counting only the utility bill and missing the usage-linked allocation.
Lab Director	Semi-fixed	Include $120,000 per year as core staffing that stays in place until capacity or compliance needs change.	Treating leadership payroll as variable when it creates fixed monthly burn.
Quality Assurance Manager	Semi-fixed	Add $90,000 per year starting Month 13 as a step-up in compliance staffing.	Waiting to add quality payroll until unit volume spikes, which understates Month 13 burn.
Testing Reagents	Variable	Apply $10 to $20 per unit based on product mix before contribution margin.	Using one blended reagent rate across all blood components.
Logistics & Delivery	Variable	Apply 5.0% of revenue in the first year, declining to 3.0% by the fifth year.	Leaving delivery out of contribution margin because drivers are also on payroll.
Sales Commissions	Variable	Apply 1.5% of revenue in the first year, declining to 0.5% by the fifth year.	Putting commissions below break-even and overstating contribution per sale.

How does break-even change from lean launch to full capacity for a blood bank?

Scenario table

Lean launch has the lowest break-even risk because fixed costs are lighter. Base and full plans add staffing, storage, and delivery capacity, so the revenue needed to stay above break-even rises with scale.

Planning assumptions only. Product mix matters because platelets start at $600 in Year 1, while cryoprecipitate starts at $220.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Year 1 lean launch	$172k	$28k	$74k	84%	$70k	Break-even is covered, so the main risk is steady donor flow.
Year 3 base scale	$468k	$67k	$101k	86%	$300k	Break-even stays covered, but staffing must match demand.
Year 5 full capacity	$769k	$95k	$120k	88%	$554k	Break-even cushion improves if cold storage and delivery stay full.

What breaks the break-even plan if revenue or costs slip?

Stress test

At the base plan, about $1.721M in monthly revenue against $741k of fixed costs leaves roughly $832k of cushion. The main risks are slower hospital contracts, higher reagent and driver payroll, and wasted cold storage.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$889k	$832k cushion	Healthy headroom, but fixed overhead still matters.
Revenue shortfall	Monthly revenue falls 10% to about $1.549M.	$889k	$660k cushion	Delayed hospital contracts cut headroom fast.
Fixed-cost pressure	Fixed costs rise 10% to about $815k a month.	$978k	$743k cushion	Payroll or compliance creep eats cushion fast.
Margin pressure	Contribution margin falls 5 points from higher reagent, storage, or labor costs.	$945k	$776k cushion	Input-cost inflation pushes the hurdle higher.
Combined pressure	Revenue falls 10%, fixed costs rise 10%, and contribution margin falls 5 points.	$1.04M	$509k cushion	Still clears break-even, but one more miss hurts.

What should you verify before signing the lease and funding launch for a blood bank?

Founder checklist

Test the Year 1 model at about $2.07M in revenue, $74.1K in monthly fixed load, and $1.115M in launch capex before you commit. Month 1 breakeven does not erase the Month 7 cash trough, which bottoms at $618K.

1Revenue plan$2.07M

Verify the Year 1 product mix can actually reach this top line, because the model only works if packed red cells, plasma, platelets, cryoprecipitate, and rare typing sell at forecast volume.

2Fixed load$74.1K/mo

Check that rent, utilities, insurance, software, marketing, legal, security, cleaning, and payroll fit this monthly burn before you sign the lease.

3Margin cushion84% CM

Confirm contribution margin (revenue left after direct costs) stays near this level after kits, reagents, labor, logistics, and sales commissions, because a 10% revenue drop and 5-point margin hit can change payback fast.

4Staffing ramp10.0 FTE

Match hiring to the Year 1 plan of 10.0 FTE (full-time equivalent), or testing delays and overtime will push unit costs above the break-even case.

5Cash trough$618K

Hold this minimum cash by Month 7 after the $1.115M launch capex stack, or the business can run short before the operating base fully settles.

6Launch volume5,100 units

Verify the donor, testing, and refrigerated delivery workflow can handle the Year 1 volume before outreach scales, because cold-chain gaps turn demand into spoilage and missed revenue.
