Which hand sanitizer manufacturing expenses are fixed, and which move with sales volume?

Cost classification

Your break-even is only as good as the cost buckets. In this model, recurring fixed overhead starts at $22,800/month before wages, while materials, packaging, labor, fulfillment, and revenue-linked plant costs rise with unit volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Alcohol Raw Material	Variable	Apply the SKU-level unit rates, from $0.04 per pocket spray to $1.50 per gallon.	Using one blended material rate and hiding mix shifts.
Packaging Materials	Variable	Model bottles, caps, pumps, pouches, and labels per unit sold.	Treating packaging waste as fixed instead of volume-linked.
Direct Filling Labor	Variable	Include filling, sealing, labeling, and assembly in unit economics by product.	Rolling all labor into salaries and overstating margin.
Shipping & Fulfillment	Variable	Use 4.0% of revenue in the first year, stepping down to 2.5% by the fifth year.	Calling fulfillment fixed when each order still ships.
Factory Rent	Fixed	Keep $12,000/month in the break-even numerator through Month 60.	Allocating rent per bottle and masking the monthly cash floor.
Administrative Office Rent	Fixed	Carry $3,000/month as fixed overhead across the planning range.	Dropping office rent from break-even because it is not factory spend.
Manufacturing Overhead	Semi-variable	Model the usage-linked portion at 1.0% of revenue.	Burying plant overhead in rent and missing scale-driven spend.
Production Technician Staffing	Semi-fixed	Add staffing in steps, from 2.0 FTE in the first year to 6.0 FTE in the fifth year.	Assuming labor rises smoothly with every added unit.

How does break-even shift from lean to full production?

Scenario table

Lean works before lease expansion, base fits steady-state staffing, and full helps with capacity planning. Fixed costs rise with headcount and space, so the break-even line moves up even as the margin improves.

Planning assumptions only; actual break-even will move with product mix, scrap, and staffing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Year 1 lean case	$159.6K	$22.7K	$59.1K	85.8%	$77.9K	Positive now, but this is the thinnest cushion.
Year 3 base case	$334.2K	$41.6K	$79.1K	87.6%	$213.6K	Good steady-state case with a solid buffer above break-even.
Year 5 full capacity case	$480.3K	$55.6K	$92.4K	88.4%	$332.3K	Highest cushion, but only if the larger fixed load stays covered.

What pressures could push this sanitizer plant toward break-even?

Stress test

The base plan clears break-even with a wide cushion, but the margin gets tighter fast if revenue slips, alcohol or bottle costs jump, or fixed payroll and overhead rise before repeat orders.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$709K	$887K cushion	Base plan clears break-even by a wide margin.
Revenue shortfall	Revenue falls 20% to $1,277K.	$709K	$568K cushion	Sell-through slows, but the plant still clears break-even.
Fixed-cost pressure	Fixed costs rise 10% to $650K.	$780K	$816K cushion	Overhead creep raises the hurdle, but coverage stays solid.
Margin pressure	Variable expenses rise 10% to about 184%.	$723K	$873K cushion	Input-cost spikes squeeze margin first.
Combined pressure	Revenue falls 20%, variable expenses rise to 184%, and fixed costs rise 10%.	$796K	$481K cushion	Alcohol spikes, bottle shortages, and early hiring can cut the cushion fast.

What should a hand sanitizer maker verify before signing the factory, staffing, and inventory commitments?

Founder checklist

Don't sign the factory, staffing, or inventory commitments until the mix clears the margin math and the Month 2 cash trough is funded. This model only looks safe if supplier lead times, 6,849-unit monthly capacity, and the $1.087M cash need all hold.

1Supplier locks6 inputs

Lock alcohol, bottles, pumps, caps, pouches, and labels before buying inventory so one late part does not stall the line or push the Month 2 cash trough deeper.

2Demand proof185K units

Check that the first-year mix of 185,000 units is backed by real buyer demand, not just a forecast, because break-even only works if orders keep pace with planned output.

3Unit margin$1,035 / $862

Test the blended average selling price and contribution margin against the model's $1,035 sale price and $862 contribution per mixed unit so pricing still covers variable costs.

4Capacity ramp6,849/mo

Prove the line and staffing can sustain at least 6,849 mixed units a month, and confirm the supplier lead times can support that run rate without expediting.

5Cost base$59.1K/mo

Add the $22.8K monthly fixed overhead to about $36.3K of Year 1 payroll, and keep QA work inside the 0.5% of revenue budget so losses do not creep in.

6Cash runway$1.087M

Hold at least $1.087M for the Month 2 low point, then delay the second equipment line until sell-through supports the 9-month payback.
