Which soap expenses are fixed and which move with sales?

Cost classification

Break-even only works if each expense matches what drives it: bars, orders, or months. If packaging or fulfillment is treated as fixed, the Month 2 break-even can look safer than the cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw materials, oils, lye, fragrance, and additives	Variable	Apply per unit produced, since ingredients rise with each bar or gift set.	Treating bulk ingredient buys as fixed because cash is paid upfront.
Individual packaging, labels, gift boxes, and fillers	Variable	Model per unit or per order; packaging moves with sales volume.	Parking packaging in overhead and overstating margin at higher order counts.
Direct production labor and set assembly labor	Variable	Include the per-unit labor tied to making bars and assembling gift sets.	Mixing per-unit labor with base payroll and hiding true unit margin.
Marketing and advertising	Variable	Use the revenue percentage from the model, starting at 8.0% in the first year.	Using one flat monthly amount even when ad spend scales with sales.
Shipping and fulfillment	Variable	Use the revenue percentage from the model, starting at 4.0% in the first year.	Treating fulfillment supplies and shipping activity as fixed overhead.
Workshop rent	Fixed	Carry $1,500 per month through the relevant planning range.	Spreading rent per bar and assuming it disappears when volume dips.
Workshop utilities	Semi-variable	Keep the $300 monthly base, but watch for production-linked usage as batches rise.	Calling all utilities fixed when heat, water, and power follow production.
Base payroll	Semi-fixed	Hold core salaries steady, then step them up as roles start and FTE levels increase.	Modeling every payroll dollar as variable with units sold.

How does break-even change across lean, base, and full soap-making formats?

Scenario table

The lean case breaks even by Month 2 because fixed costs stay tight; the base case adds staff and lifts the hurdle; the full case has the strongest sales, but it only works if cash supports the bigger payroll.

Planning cases only; actual cash will move with mix, waste, labor, and selling costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean soap line	$23.3k	$11.6k	$7.5k	50.4%	$4.2k	Break-even lands by Month 2, but the cushion is thin.
Base soap line	$41.0k	$18.4k	$14.8k	55.1%	$7.8k	Positive cash stays intact, but added payroll raises the hurdle.
Full-scale soap line	$66.3k	$27.0k	$17.7k	59.2%	$21.6k	Best cushion, as long as output keeps pace with staff.

What breaks first if soap sales slow or costs climb?

Stress test

The plan clears break-even in the first year, but the cushion is not unlimited. Sales slippage, Year 2 payroll, and higher unit costs are the first places the margin gets squeezed.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$145,000	$134,500 cushion	Year 1 revenue stays well above break-even.
Revenue shortfall	Year 1 revenue slips to $150,000.	$145,000	$5,000 cushion	A small sales dip still clears break-even, but the cushion gets thin.
Fixed-cost pressure	Year 2 staffing lifts annual fixed costs to $135,580.	$217,200	$62,300 cushion	Payroll comes before repeat orders and pushes break-even up.
Margin pressure	Direct unit costs rise 10% from current levels.	$154,500	$125,000 cushion	Higher oil, fragrance, packaging, or set build costs hit margin first.
Combined pressure	Year 1 revenue slips to $150,000, Year 2 fixed costs land, and unit costs rise 10%.	$231,400	$81,400 gap	This is the break point: lower sales and higher costs move together.

Can this soap shop hit break-even before you sign the lease, buy more equipment, or hire help?

Founder checklist

Test the model against break-even first. Year 1 sales are about $279.5K, or $23.3K a month, so the bigger bets only make sense if demand, margin, capacity, and cash all hold together.

1Revenue Proof$150K/mo

Verify there is a real path to about $150K in monthly revenue before fixed costs expand, because Year 1 sales are only about $23.3K a month.

2Fixed Load$2.2K/mo

Check the core shop overhead of rent, utilities, insurance, software, hosting, accounting, and maintenance first, because that fixed load is what break-even must cover before you add payroll.

3Margin Check52% CM

Here’s the quick math: Year 1 product sales are about $279.5K, unit COGS is about $99.7K, and marketing plus shipping take 12% of sales, leaving about 52% contribution margin.

4Curing Space15K/mo

Confirm curing, packing, and labeling can handle roughly 15K equivalent units a month, because the space plan needs to map to about 285K Year 1 units without quality slips.

5Supply Lock5 inputs

Lock supply for oils, lye, additives, labels, boxes, and gift materials before scaling ads, because a missed input or price jump will hit both output and margin.

6Cash Runway$1.059M

Keep startup spend and owner pay separate from operating break-even; launch capex totals about $42.2K, and you should not add the production assistant or marketing manager until order volume supports payroll and the model still holds near the $1.059M minimum cash point in Month 50.
