Cost classification

Break-even gets reliable only when fixed overhead stays out of per-unit math and volume-linked inputs reduce contribution margin. Rent and insurance sit in monthly overhead, while materials, packaging, and payment fees move with restored pieces or revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Workshop Rent	Fixed	Use $2,800 per month as baseline overhead before any restored unit is sold.	Spreading rent across each skillet and making margins look volume-dependent.
Liability Insurance	Fixed	Use $450 per month as a required operating expense in the break-even base.	Treating insurance as a per-job charge instead of monthly protection.
Equipment Insurance	Fixed	Use $250 per month with other fixed workshop overhead.	Dropping it from break-even because it is smaller than rent.
Restoration Materials	Variable	Apply per restored piece; listed skillet inputs total $5.60 before labor and overhead.	Using one blended material amount for every cookware type.
Shipping Packaging	Variable	Apply 1.8% of first year revenue, or about $2,376 on $132,000 of sales.	Modeling packaging as flat even when shipped volume rises.
Platform Payment Fees	Variable	Apply 1.2% of first year revenue, or about $1,584 on $132,000 of sales.	Forgetting fees when calculating contribution margin.
Electricity Water	Semi-variable	Start with the $650 monthly model amount, then watch oven cycles and wash volume.	Calling utilities fixed forever while production hours climb.
Restoration Tech Staffing	Semi-fixed	Add labor in steps as capacity grows; one tech moves from 0.5 FTE in the first year to 1.0 FTE in the second year.	Treating trained shop labor as fully variable per skillet.

How does break-even change from a lean launch to a full-service restoration shop?

Scenario table

Break-even improves as revenue grows faster than payroll and workshop overhead. The lean and base cases still run negative on a monthly basis, while the full-service case clears the line and matches the Month 26 break-even signal.

Planning assumptions only; actual results will move with intake speed, labor mix, and scrap rates.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean restoration launch	$11,000	$3,408	$18,092	69.0%	-$10,500	High break-even risk; volume covers variable costs but not the shop burden yet.
Base workshop buildout	$28,417	$6,875	$24,042	75.8%	-$2,500	Still tight; added staff lift fixed cost faster than monthly profit.
Full-service scale	$51,333	$10,900	$28,433	78.8%	$12,000	Break-even is reached, so the model starts to build real cushion.

What breaks the break-even plan for a cast iron restoration shop?

Stress test

Weak mail-in demand, slower seasoning cycles, and higher workshop bills are the main break-even risks. A small slip in volume or margin moves this model from near break-even to a real monthly gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$205k	$0 gap	The plan only works if volume stays on target.
Revenue shortfall	Revenue falls 20% from the break-even target.	$205k	$36k gap	A sales miss this size leaves too little contribution to cover fixed costs.
Fixed-cost pressure	Monthly fixed costs rise 10%.	$226k	$21k gap	Rent, utilities, or labor creep can erase the cushion fast.
Margin pressure	Contribution margin falls from 88.2% to 83.2%.	$217k	$12k gap	Rework or slower seasoning cycles push break-even higher.
Combined pressure	Revenue falls 20%, fixed costs rise 10%, and margin falls 5 points.	$227k	$63k gap	Multiple leaks at once create a large monthly cash hole.

What should you verify before signing the workshop lease and buying restoration equipment?

Founder checklist

Don’t commit until the order path, pricing, and shop flow can support break-even. This model needs 129 monthly pieces, and Year 1 demand averages only about 69 pieces a month.

1Order Intake129/mo

Verify the mail-in intake flow, photo capture, liability terms, and return packaging can reliably support 129 pieces a month before you sign the lease.

2Price Ladder$110-$225

Test that buyers accept the full service price range, because the mix depends on skillet at $125, Dutch oven at $225, griddle at $155, corn pan at $110, and combo cooker at $195.

3Unit Margin≈91% CM

Confirm direct materials stay near $4.4 to $10.0 per piece and the listed variable fees stay close to 4.5% of revenue, or contribution margin will slip.

4Fixed Burn$18.1K/mo

Check that booked orders can cover about $18.1K a month of rent, utilities, insurance, software, and Year 1 wages before you add more payroll.

5Flow & Safety2.7 FTE

Confirm the stripping, rinse, dry, seasoning, QC, and packing line works with 2.7 FTE in Year 1, and make sure ventilation and safety are ready before chemicals and ovens go live.

6Cash Runway$873K

Protect the Month 36 cash trough and stage the $120K listed capex, because the model needs $873K minimum cash and does not pay back until Month 49.
