Cost classification

Break-even is only useful if fixed overhead stays out of unit margin and run-level costs stay in it. Here’s the quick math: first-year fixed salaries are about $26.1k/month before lease and subscriptions, while shipping and commissions take 7.0% of revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Manufacturing Facility Lease	Fixed	Include $12,000/month in overhead before testing unit economics.	Allocating rent per unit and hiding the true monthly hurdle.
Year 1 Salaried Operations Team	Fixed	Treat General Manager, Production Supervisor, Quality Assurance Lead, and Account Manager salaries as about $26.1k/month of fixed payroll.	Modeling salaried roles like direct labor that falls when units dip.
Unit Materials and Direct Unit Labor	Variable	Apply raw ingredients, bottles, cartons, labels, wax, beans, cans, oil, and direct unit labor to each unit produced.	Treating packaging, scrap, rework, and run labor as overhead.
3PL Logistics and Shipping Fees	Variable	Deduct 4.0% of first-year revenue, stepping down to 3.2% by Year 5.	Leaving fulfillment below the gross margin line and overstating contribution.
B2B Sales Commissions	Variable	Deduct 3.0% of first-year revenue, stepping down to 2.2% by Year 5.	Counting commissions as discretionary overhead instead of sales-linked expense.
Utilities, Testing, Sanitation, and Calibration	Semi-variable	Model usage-linked items like sterilization energy, refrigeration electricity, quality testing, sanitation supplies, and equipment calibration with production volume.	Using one flat overhead rate when more runs create more checks and cleaning.
Marketing and Trade Show Budget	Semi-fixed	Start with $3,500/month, then step it up only when the sales plan needs more events or campaigns.	Spreading the spend across units and making contribution margin look weaker.

How does break-even shift from lean to base to full production for this small batch manufacturer?

Scenario table

Lean output only just covers fixed overhead, so the cushion is thin. As volume rises, overhead gets spread across more units, but order mix still matters because each product line uses different inputs and setup time.

Planning cases only. Actual break-even will move with product mix, setup time, and order timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean batch floor	$64.0k	$17.3k	$46.7k	72.9%	$0	Just clears fixed costs, so cushion is thin.
Year 1 base run	$201.7k	$54.6k	$46.7k	72.9%	$100.4k	Break-even lands in Month 1, with a solid cushion.
Year 3 full run	$507.8k	$129.7k	$65.0k	74.5%	$313.1k	Higher volume absorbs overhead better and lowers risk.

What breaks the break-even plan if revenue slips or costs creep up?

Stress test

This plan has wide headroom because monthly revenue is far above the $64k break-even line. The real risk is margin leakage from underbooked weeks, overtime, scrap, rework, and setup time that blocks billable runs.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$64k	$1,953k cushion	Revenue sits far above break-even.
Revenue shortfall	Revenue falls 20% to about $1,613k.	$64k	$1,549k cushion	Still well above break-even, but cash tightens.
Fixed-cost pressure	Fixed overhead rises by $10k.	$777k	$1,240k cushion	Overhead creep narrows headroom.
Margin pressure	Variable costs rise 5 points.	$688k	$1,329k cushion	Scrap, rework, and downtime hit margin first.
Combined pressure	Revenue falls 20%, margin compresses 5 points, and fixed overhead rises $10k.	$835k	$778k cushion	Headroom shrinks fast if all three hit together.

What should the founder verify before locking in the first lease and equipment buy?

Founder checklist

Before you sign the lease or order equipment, confirm the first operating month can carry the fixed load. Here’s the quick math: Year 1 fixed payroll is about $26.1K per month, fixed overhead is about $46.7K per month, signed demand should clear the $64K monthly test, and cash dips to $1.112M in Month 2.

1Order pipeline$64K/mo

Verify signed or near-signed orders clear the $64K monthly test so fixed costs are not funded by idle capacity.

2Fixed load$46.7K/mo

Confirm the $12K lease is worth it only if the full fixed stack stays near $46.7K a month, including ERP, maintenance, marketing, insurance, admin, and base payroll.

3Run marginMOQ covers setup

Check that minimum order quantities cover setup, packaging, scrap, and rework, or each small run adds busy work without enough cash back.

4Payroll ramp$313K/yr

Keep Year 1 payroll aligned with utilization; the core team totals about $313K a year, and the process engineer does not start until Month 13.

5Cash reserve$1.112M

Hold reserve for the Month 2 trough, because the model's minimum cash lands at about $1.112M before collections catch up.

6Input timingMonth 1-9

Lock lead times for bottles, labels, cartons, cans, jars, oils, wax, beans, and active bases, and keep bottling, mixing, cold brew, labeling, racking, testing, HVAC, and ERP on schedule so launch volume can flow.
