Cost classification

Break-even only works when fixed overhead is separated from costs that rise with trades and revenue. In this model, Month 16 break-even depends on treating payroll as stepwise and revenue-linked fees as variable.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Include $5,000/month in baseline overhead from Month 1.	Tying rent to trade volume.
Software Licenses	Fixed	Include $1,500/month in monthly fixed costs.	Burying recurring tools under engineering spend.
Legal & Audit Retainer	Fixed	Include $2,000/month from launch month.	Treating compliance support as optional.
Compliance & Regulatory Fees	Fixed	Include $1,200/month in fixed overhead.	Mixing fixed fees with per-transaction fees.
Payroll	Semi-fixed	Use $58,750/month in the first year, then step up as full-time equivalents rise.	Modeling staff as variable per trade.
Technology Infrastructure & Hosting	Variable	Model as 7.0% of revenue in the first year.	Assuming cloud and hosting stay flat.
Market Data & Clearing Firm Fees	Variable	Model as 6.0% of revenue in the first year.	Ignoring data-feed and clearing scale.
Regulatory Transaction Fees	Variable	Model as 2.0% of revenue in the first year.	Confusing per-transaction fees with fixed compliance fees.

How does break-even shift from lean launch to full scale for this stock trading app?

Scenario table

Lean launch carries the most break-even risk because the first-year fixed load is heavy. By Year 2, the model reaches break-even in Month 16, and the Year 5 mix adds the widest cushion as higher-value traders lift margin.

Planning cases only; actual results will vary with conversion, trading activity, support load, and compliance cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch, Year 1 mix	$991k	$198k	$793k	80.0%	-$683k	Year 1 stays loss-making, so break-even is still under pressure.
Base growth, Year 2 mix	$1.355M	$249k	$1.105M	81.6%	$895k	Break-even has already arrived by Month 16, and cash turns positive in Year 2.
Full scale, Year 5 mix	$3.966M	$535k	$3.430M	86.5%	$55.7M	The higher trader mix gives the widest cushion, but fixed costs still need tight control.

What breaks break-even if trading activity slows or costs rise?

Stress test

Break-even is tight here: the model needs about $991,000 a month, and cash still bottoms at -$367,000 in Month 15. If premium conversion or active trading slows, the gap widens fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$991,000/month	$0 gap	Month 15 cash trough is -$367,000.
Revenue shortfall	Active traders and pro traders lag, so retail mix stays heavy.	$991,000/month	$766,000 gap	If premium users stall, the revenue target slips.
Fixed-cost pressure	Pull the Year 5 fixed-cost run rate into the first operating year.	$4,286,000/month	$3,295,000 gap	Payroll and marketing can outrun monetization fast.
Margin pressure	Keep Year 1 variable expense load at 200% instead of moving toward 135% by Year 5.	$1,468,000/month	$477,000 gap	High hosting and market-data load keeps margin weak.
Combined pressure	Let revenue lag while Year 5 fixed costs and Year 1 margin pressure hit at the same time.	$6,351,000/month	$5,360,000 gap	Cash breaks before the model reaches scale.

What should you verify before you scale paid growth in a stock trading app?

Founder checklist

Don’t scale paid acquisition until brokerage, compliance, and market-data rails are live and your CAC stays near target. With about $70.9K in monthly fixed burn, $560K of upfront setup, and minimum cash down to -$367K in Month 15, break-even only works if launch quality and retention show up early.

1CAC Guardrail$50 → $35

Check that paid acquisition can stay near the $50 Year 1 CAC target and move toward $35 by Year 5 before you scale the $100K-to-$2.5M marketing plan.

2Trade RailsLive first

Verify brokerage and clearing integration is live before spend rises, because orders must route and settle cleanly for the app to work.

3KYC/AMLNo gaps

Make sure Know Your Customer and anti-money laundering steps are complete end to end before opening the funnel.

4Data LicenseMonth 1-60

Confirm market data licensing runs through Month 60 and matches expected user and trade volume, or trading fees and outages can break the model.

5Ops Staffing$110K + $60K

Staff compliance at $110K and support at $60K before trade volume rises; Year 1 fixed regulatory fees add $1,200 a month, so burn stays visible.

6RunwayM15, -$367K

Keep enough cash for the Month 15 low point and separate the $560K one-time build and setup spend from the $70.9K monthly fixed load.
