Cost classification

If you tag fixed overhead as variable, Month 8 break-even can look safer than it is. Use revenue-linked rates for unit costs, then hold platform, rent, and payroll steady until a real capacity step.

Expense	Cost	Break-Even Treatment	Common Mistake
Raw Ingredient & Blending Costs	Variable	Model at 8.0% of revenue in the first year, falling to 6.0% in the mature year.	Treating formula complexity as free.
Packaging & Fulfillment Costs	Variable	Model at 4.0% of revenue in the first year, improving to 3.0% by the mature year.	Burying custom labels in overhead.
Shipping & Logistics Costs	Variable	Model at 5.0% of revenue in the first year, then 4.0% by the mature year.	Ignoring free-shipping leakage.
Payment Processing Fees	Variable	Model at 2.5% of revenue in the first year, then 2.0% by the mature year.	Forgetting it scales with revenue.
Website Hosting & Platform Fees	Fixed	Hold at $1,500 per month from Month 1 through Month 60.	Tying it to order count.
Office Rent & Utilities	Fixed	Hold at $3,000 per month inside the current planning range.	Adding lease-like spend too early.
Wages	Semi-fixed	Start near $29.4k per month in the first year, then step up as FTEs increase.	Hiring ahead of confirmed order volume.
Paid Acquisition	Semi-variable	Use the $150,000 first-year budget and $75 CAC together to test customer volume.	Double-counting ad budget and CAC.

How does break-even shift from a lean launch to a full rollout for personalized protein powder?

Scenario table

As the business moves from a lean launch to a full rollout, fixed costs rise fast, so the break-even revenue hurdle rises too. The higher contribution margin helps, but it does not erase the need for stronger subscription volume.

These are planning thresholds, not promised demand or profit.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$653k	$127k	$526k	80.5%	$0	Leanest path to proof, with little room for missed conversion.
Base scale	$985k	$182k	$803k	81.5%	$0	Enough scale to fund added marketing and hires, but demand still has to land.
Full rollout	$2,354k	$353k	$2,001k	85.0%	$0	Works only with strong subscription growth and tight execution.

What breaks the break-even plan for personalized protein powder?

Stress test

The plan is tight at $653k revenue and $526k fixed costs. CAC above $75, first-order revenue below $766, trial-to-paid conversion below 40%, or fulfillment above 40% plus shipping above 50% will push it out of break-even fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$653k	$0 cushion	Thin cushion; any miss turns operating profit negative.
Revenue shortfall	Revenue drops 10% to about $588k.	$653k	$53k gap	A small sales miss creates a real operating loss.
Fixed-cost lift	Fixed costs rise 10% to about $578k.	$718k	$53k gap	Higher overhead lifts break-even even if sales hold.
Margin pressure	Variable expenses rise to 24.5%.	$696k	$33k gap	A thinner margin cuts the cushion fast.
Combined pressure	Revenue drops 10%, variable expenses rise to 24.5%, and fixed costs rise 10%.	$766k	$135k gap	When sales and costs move together, the model turns deeply negative.

What should you verify before locking the first build and ad spend for personalized protein powder?

Founder checklist

Test the unit economics before you buy inventory or add people. The launch only works if paid-trial demand, margin, and cash all hold through Month 8, when the model shows a $553K minimum cash need and breakeven.

1Trial Funnel2.0% / 40.0%

Before you spend the $150K Year 1 marketing budget, verify visitors can convert to paid trials at 2.0% and then to paid subscribers at 40.0%, or CAC can drift above the $75 target.

2Unit Margin80.5% CM

Keep ingredient and blending near 8.0%, packaging and fulfillment near 4.0%, shipping near 5.0%, and processing near 2.5% so the model's Year 1 margin still holds.

3Monthly Burn$40.1K/mo

Fixed costs run about $10.7K a month, plus roughly $29.4K a month in Year 1 wages, so know this burn before you sign leases or lock software.

4Hiring Gate$653K/mo

Delay the software engineer and warehouse coordinator until monthly revenue clears the $653K break-even gate, or headcount will outrun cash.

5Cash Cushion$553K

Hold at least this cash through Month 8, because the model's minimum cash point lands there and any delay in conversion or fulfillment makes the dip deeper.

6Launch Capex$265K

Only commit after you can fund the first build, which totals $265K across equipment, algorithm development, warehouse setup, inventory, IT, platform work, branding, and QC lab gear.
