Cost classification

Break-even gets reliable only when unit-linked spend stays in contribution margin and stable monthly bills stay fixed. Ingredients, packaging, direct brewing labor, and revenue-based allocations move with volume; rent and insurance don’t.

Expense	Cost	Break-Even Treatment	Common Mistake
Organic tea, cane sugar, and flavorings	Variable	Include in per-unit margin. Standard bottled flavors carry $0.22 per unit before packaging and labor.	Averaging ingredient spend without checking flavor-level margin.
Special botanicals	Variable	Assign only to seasonal batches. The modeled botanical input is $0.15 per Seasonal Blend unit.	Spreading premium inputs across every SKU.
Bottles, caps, and labels	Variable	Treat as batch-linked spend. Standard bottled SKUs carry $0.14 per unit for packaging and labels.	Treating packaging as overhead instead of batch-linked spend.
Keg cleaning and sanitization	Variable	Apply to bulk keg volume. The model uses $2.00 per Bulk Classic Keg unit.	Using bottled packaging logic for keg sales.
Direct brewing labor	Variable	Keep in unit economics: $0.08 per standard bottle, $0.09 per Seasonal Blend unit, and $2.00 per keg.	Moving all brewing labor into fixed payroll.
Fixed monthly overhead	Fixed	Use stable monthly charges: rent $3,500, insurance $300, software $400, legal and accounting $500, equipment lease $800, and vehicle lease $600.	Reducing these bills automatically when sales dip.
Utilities brewery and office	Semi-variable	Model the $1,200 monthly utility base, then add the 0.2% brewery utilities allocation tied to revenue.	Treating refrigeration and utilities as fully fixed.
Production overhead, testing, depreciation, and maintenance allocations	Variable	Deduct 0.8% of revenue in margin math: 0.2% overhead, 0.1% testing, 0.3% depreciation, and 0.2% maintenance.	Leaving revenue-linked allocations below gross margin.

How does break-even shift from a lean launch to full production for a kombucha brewery?

Scenario table

Lean launch is closest to break-even, but scale quickly widens the cushion because revenue grows faster than fixed costs. The tradeoff is mix: keg volume lifts sales fast, while more bottled volume adds packaging load.

Planning assumptions only; actual break-even will move with volume mix, pricing, and overhead.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Launch (Year 1)	$52,813	$7,096	$29,800	86.6%	$15,917	Break-even is tight, so launch volume discipline matters.
Base Growth (Year 3)	$138,517	$17,532	$43,550	87.3%	$77,435	Break-even sits well below sales, so the cushion is healthier.
Full Production (Year 5)	$285,813	$33,395	$46,883	88.3%	$205,534	Full scale gives the widest cushion, but mix still drives margin.

What breaks the kombucha break-even plan first?

Stress test

Base case has an $18,388 monthly cushion, so it clears break-even now. The risk is simple: lower sell-through, packaging inflation, spoilage, or higher refrigeration and utility costs can erase that cushion fast, and a $1,000 revenue miss cuts about $866 of contribution.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$34,425/month	$18,388 cushion	Healthy on paper, but still close enough to feel cost spikes.
Revenue shortfall	Monthly revenue falls by $5,000 on weaker sell-through.	$34,425/month	$13,388 cushion	A $5,000 sales miss burns about $4,330 of contribution.
Fixed-cost pressure	Fixed costs rise by $2,000 a month from rent, utilities, or payroll.	$36,735/month	$16,078 cushion	Every extra fixed dollar pushes break-even higher, even if sales hold.
Margin pressure	Packaging, spoilage, and refrigeration push variable costs up 3 points.	$35,650/month	$17,163 cushion	Small margin drift trims the room to absorb mistakes.
Combined pressure	Revenue falls $5,000, fixed costs rise $2,000, and variable costs rise 3 points.	$38,038/month	$9,775 cushion	This drops the cushion below the Year 1 buffer and turns fragile fast.

What should a kombucha founder verify before signing the lease and buying the line?

Founder checklist

Before you sign the lease or buy the line, make sure Year 1 sell-through, cash, and timing still work at the $34,425 monthly break-even target. Protect the $1.121 million cash floor in Month 2, or the plan is too tight.

1Sell-through50,000 units

Verify Year 1 demand can absorb the 50,000-unit plan across bottles and kegs, because break-even only works if volume keeps moving.

2Lease load$7.3K/mo

Verify the $3,500 lease still fits inside the $7,300 fixed-cost base, because this cost stays on the books even if sales run light.

3Unit margin86.6% CM

Verify the bottle and keg mix keeps contribution at this level after unit costs, testing, distribution, and commissions, because that margin pays the fixed stack.

4Payroll ramp$22.5K/mo

Verify the Year 1 team can run production and sales at this payroll before the Year 2 hire ramp starts, or labor will outrun output.

5Cash floor$1.121M

Verify working capital covers the Month 2 trough, because the $45,000 tanks, $60,000 bottling line, $25,000 cold storage, and $15,000 lab gear hit before sales catch up.

6Launch gateMonth 4

Verify bottles, caps, labels, quality testing, and cold storage before retail or wholesale launch, and test keg readiness too, because one weak step can spoil sell-through.
