Cost classification

Break-even gets reliable only when recurring overhead, usage-linked fees, and scale hires are separated. Keep the $250,000 one-time setup spend out of monthly break-even math.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent	Fixed	Include $3,000 per month in fixed overhead from Month 1 through Month 60.	Tying rent to subscriber growth instead of treating it as a monthly hurdle.
Legal and compliance retainer	Fixed	Include $2,000 per month before calculating revenue needed to cover operations.	Dropping compliance from break-even because it doesn’t produce sales directly.
General software licenses	Fixed	Include $1,500 per month as baseline operating overhead.	Putting core licenses into usage fees and understating fixed burn.
Fixed payroll for CEO and lead engineering	Fixed	Include first-year payroll of $150,000 for the CEO/Founder and $180,000 for the Lead AI Engineer.	Ignoring founder payroll, which makes break-even look easier than cash reality.
Cloud infrastructure and API usage	Semi-variable	Model the baseline at 4.0% of first-year revenue, then stress-test spikes from account count and trading volume.	Treating all cloud spend as fixed when heavy trading can lift usage quickly.
Financial market data fees	Variable	Apply 3.0% of first-year revenue as a usage-linked service delivery expense.	Forgetting that data needs can rise as customers and trading activity grow.
Customer acquisition marketing	Variable	Use 8.0% of first-year revenue in operating break-even, and reconcile it to the $120,000 annual marketing budget.	Double counting planned marketing budget and revenue-based acquisition spend.
Scale hiring for data, support, marketing, and compliance	Semi-fixed	Add roles in steps when scale requires them, such as the Data Scientist and Customer Support Lead starting in Month 13.	Spreading future hires across every early customer instead of adding capacity in steps.

How does break-even shift from a lean launch to a full AI stock trading setup?

Scenario table

Lean breaks even first because fixed costs are lowest. Base needs the most cover since payroll rises faster than the margin gain, while full improves pricing and mix but still carries a heavier cost base.

Planning assumptions only; if marketing is committed spend, add it on top of these break-even cases.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$45,455	$7,955	$37,500	82.5%	$0	About 277 active accounts cover fixed costs before committed marketing spend.
Base operating case	$101,243	$14,576	$86,667	85.6%	$0	About 479 active accounts cover the heavier payroll base.
Full scale case	$115,315	$12,815	$102,500	88.8%	$0	About 410 active accounts still clear the larger cost base.

What breaks the break-even plan if revenue slows or costs rise?

Stress test

This plan is tight at the base case: about $45,500 in monthly revenue only covers the $37,500 fixed load at an 82.5% contribution margin. A 15% sales dip or a 5-point margin hit pushes it back into deficit.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$45,500	$0 cushion	No room for slippage.
Revenue shortfall	Monthly revenue drops 15%.	$45,500	$5,600 gap	A small sales miss creates a deficit.
Fixed-cost pressure	Fixed costs rise 20% to $45,000.	$54,500	$9,000 gap	Overhead adds about $9,000 to break-even.
Margin pressure	Contribution margin falls 5 points to 77.5%.	$48,400	$2,900 gap	Higher cloud, data, or payment fees raise the target.
Combined pressure	Revenue drops 15%, margin falls to 77.5%, and fixed costs rise 20%.	$58,100	$15,100 gap	All three hits create a large monthly gap.

What should you verify before you lock in major recurring spend on an AI stock trading platform?

Founder checklist

Before you commit, make sure the platform can launch cleanly, trade through approved vendors, and hold enough cash to reach Month 7. The model needs $45,500 a month of revenue to clear break-even, so don’t scale hires or ads ahead of that line.

1Compliance SetupPre-launch

Verify the legal setup, risk rules, and the $1,200 cybersecurity plus $800 insurance stack before launch so the product can scale without obvious control gaps.

2Vendor Terms3.0% COGS

Lock broker, execution, and market data terms before trading volume ramps, or the cost base can drift above plan.

3Cloud Load4.0%→3.0%

Test cloud capacity before account growth so the platform can handle more users without pushing cloud and API costs past the model.

4Setup Spend$250K

Keep the $250,000 one-time build separate from monthly break-even so you do not confuse launch capex with operating burn.

5Cash Runway$617K

Hold at least $617,000 of cash through Month 7, and delay hires if revenue is still below $45,500 a month.

6Demand Proof$150 CAC / 15.0%

Pressure-test the $150 CAC and 15.0% trial-to-paid conversion before marketing scale so the funnel can support break-even.
