Which anti-tarnish strip expenses are fixed, and which move with sales?

Cost classification

Break-even is reliable only when fixed overhead stays above the line and sales-linked costs reduce contribution margin. Here, ads, 3PL fees, packaging, and unit inputs are margin drag, not overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Laboratory Lease	Fixed	Carry $4,500/month in fixed overhead from Month 1 through Month 60.	Spreading rent across units and hiding the monthly cash hurdle.
General Insurance	Fixed	Carry $1,200/month as a fixed operating charge.	Modeling insurance as a percent of sales.
Software Subscriptions	Fixed	Carry $850/month in fixed overhead for the planning range.	Tying subscriptions to order volume without a plan change.
Year 1 Payroll	Fixed	Use $353,000/year, or about $29,417/month, in fixed overhead.	Treating salaried roles as variable labor.
Logistics Coordinator	Semi-fixed	Add the $55,000/year role as a step-up starting Month 13.	Including the role in Month 1 break-even.
Digital Marketing and Ads	Variable	Subtract 10.0% of first-year revenue from contribution margin.	Treating ads as overhead instead of margin drag.
E-commerce and 3PL Fees	Variable	Subtract 6.0% of first-year revenue from contribution margin.	Leaving fulfillment fees below EBITDA instead of gross margin.
Unit-level Production Inputs	Variable	Charge raw compound, substrate, packaging, assembly labor, and testing per unit sold.	Treating packaging and testing as fixed overhead.

How does break-even shift across lean, base, and full traction in anti-tarnish strip sales?

Scenario table

Break-even moves fast because the revenue mix changes both margin and fixed labor load. The lean case is basically flat, the base case has a solid cushion, and full traction widens that cushion if discounting stays under control.

Planning cases only; mix, pricing, and staffing can move break-even faster than these averages.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch mix	$60k	$19k	$41k	68%	$0k	Revenue only covers the monthly load, so one weak month turns red.
Base Year 1 run rate	$195k	$62k	$41k	68%	$92k	There is a clear cushion here, so normal demand swings should stay above break-even.
Full traction Year 3 mix	$468k	$138k	$51k	70%	$278k	Strong cushion, but it depends on DTC pack sales, bulk rolls, and tight wholesale discount control.

What breaks the break-even plan for anti-tarnish strip sales?

Stress test

At about $195k in Year 1 monthly revenue, the plan has a wide cushion. It gets fragile if repeat orders slow, discounts deepen, or paid acquisition stays above 10% of revenue, because those push break-even toward the $60k to $74k band.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$60k	$135k cushion	Healthy cushion unless repeat orders slip.
Revenue shortfall	Revenue falls 20% from the base plan.	$60k	$96k cushion	A 20% sales drop still covers fixed costs.
Fixed-cost pressure	Fixed costs rise 15% from the base plan.	$69k	$126k cushion	Lease, labor, or freight inflation eats cushion.
Margin pressure	Contribution margin falls 5 points.	$64k	$130k cushion	Discounting or ad costs above 10% push break-even up.
Combined pressure	Fixed costs rise 15% and margin falls 5 points.	$74k	$121k cushion	Two hits at once bring the plan close to the edge.

What should you verify before locking inventory, payroll, and ad spend for anti-tarnish strip sales?

Founder checklist

Not yet, unless product QC, supplier terms, and a cash cushion are already locked. The model breaks even in Month 1, so the real test is whether demand and supply are ready before you spend.

1Batch QCTested batch

Verify strip chemistry passes quality testing before broad sales, because one bad batch can trigger returns and break the unit-cost math.

2Pack MOQs5 SKUs

Confirm packaging minimum order quantities across all five product lines before bulk buying boxes or sleeves, so cash does not get trapped in the wrong mix.

3Reorder LeadPre-ads

Know your reorder lead time before you spend on ads, or demand can outrun supply and force rushed freight or stockouts.

4Base Burn$40.6K/mo

Carry the opening fixed load from lease, software, legal, R and D, office costs, and Year 1 wages, because that is the monthly burn you must cover first.

5Cash Reserve$1.14M

Keep the Month 1 minimum cash reserve in place before you lock equipment and payroll, since that is the model's lowest cash point.

6Revenue Ramp$60K/mo

Prove a steady $60K monthly sales path before adding more headcount, and track the 10% ads plus 6% e-commerce and 3PL fees and damaged shipments separately.
