Cost classification

Break-even is only reliable when revenue-linked spend stays below the gross margin line and overhead stays fixed. Here, raw inputs, packaging, shipping, and card fees move with sales; rent, hosting, and admin do not.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw Vitamins Supplements	Variable	Deduct 8.0% of first year revenue before contribution margin.	Treating ingredients as overhead instead of revenue-linked spend.
Packaging Materials	Variable	Deduct 2.0% of first year revenue with each paid order.	Forgetting pack materials scale with subscriber volume.
Fulfillment & Shipping	Variable	Deduct 6.0% of first year revenue as order volume grows.	Modeling shipping as fixed warehouse overhead.
Payment Processing Fees	Variable	Deduct 2.5% of first year revenue from paid transactions.	Ignoring card fees when pricing monthly plans.
Technology Platform & Hosting	Fixed	Include $3,000 per month in fixed overhead from Month 1.	Spreading hosting across units and hiding the monthly burn.
Office Rent	Fixed	Include $2,000 per month in fixed overhead from Month 1.	Assuming rent falls when sales slow.
Customer Support Specialist	Semi-fixed	Add capacity in steps, starting Month 13 at $50,000 annual salary.	Hiring too early before ticket volume needs the role.
Packaging & Fulfillment Staff	Semi-fixed	Add labor in steps, starting Month 25 at $40,000 per FTE.	Modeling fulfillment labor as fully variable by order.

How does break-even change from lean launch to base case and full scale for personalized vitamin packs?

Scenario table

Lean launch clears break-even with the tightest cushion. Base and full scale add more profit, but higher support, operations, fulfillment, and marketing spend also push fixed costs up fast.

Planning assumptions only; actual results will move with CAC, mix, and retention.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$67.3k	$12.4k	$30.3k	81.5%	$24.5k	Covers fixed costs, but the cushion is still thin.
Base case	$212.2k	$37.6k	$52.6k	82.3%	$122.1k	Best balance so far; break-even risk is low if volume holds.
Full scale	$1.41m	$213.2k	$114.9k	84.9%	$1.08m	Strong cushion, but the larger overhead needs steady demand.

What breaks the break-even plan for personalized vitamin packs?

Stress test

The base plan breaks even at about $447K, so there isn’t much cushion. A 10% sales miss, a 5-point rise in fulfillment costs, or a 10% overhead bump can push the business into a $29K to $93K gap.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$447K	$0 cushion	CAC above $60 is the first warning.
Revenue shortfall	Revenue runs 10% below plan.	$447K	$36K gap	Trial-to-paid below 65% makes the miss worse.
Fixed-cost increase	Fixed overhead rises 10% to about $400K.	$491K	$44K gap	Early hiring before active subscribers cover contribution lifts break-even.
Margin pressure	Fulfillment and shipping costs rise 5 percentage points.	$476K	$29K gap	Shipping above 60% squeezes contribution fast.
Combined pressure	Revenue falls 10%, overhead rises 10%, and fulfillment costs rise 5 points.	$540K	$93K gap	These shocks together remove the cushion.

What should you verify before the first big spend on personalized vitamin packs?

Founder checklist

Do not commit to the build, inventory, or hiring until the funnel, margin, and cash numbers still clear the model. Break-even lands in Month 5, but the Month 6 cash low point is $774K, so proof has to come first.

1Revenue per User$66.75/mo

Confirm the weighted subscription price still averages $66.75 per customer each month before you fund launch spend.

2Margin Check81.5% CM

Raw vitamins, packaging, shipping, and payment fees take 18.5% of revenue, so the pack has to keep 81.5 cents on each dollar before overhead.

3Burn Load$36.4K/mo

Year 1 fixed costs, payroll, and marketing add to about $36.4K a month, so cash has to carry that burn before launch.

4Funnel Ready5% / 65% / $60 CAC

Only approve the $80K website build after tracking shows 5% visitor-to-trial, 65% trial-to-paid, and customer acquisition cost near $60.

5Inventory Gate$30K / $25K

Time the $30K inventory buy and the $25K packaging equipment spend to real demand, or you can trap cash in stock and gear too early.

6Cash GateMonth 13 / $774K

Delay support and operations hiring until retention and fulfillment load justify it, and protect the $774K cash low point in Month 6.
