Cost classification

Break-even is reliable only when fixed overhead is separated from usage-based spend. Here, fixed overhead starts at $10,500 per month, while hosting, API fees, processing fees, and commissions move with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent and Utilities	Fixed	Use $4,500 per month from Month 1 through Month 60.	Tying rent to customer count instead of capacity.
Accounting and Audit	Fixed	Use $2,000 per month as recurring overhead.	Treating it as an occasional clean-up expense.
Cloud Hosting and Infrastructure	Variable	Model at 8.0% of first-year revenue, then lower by year as provided.	Holding hosting flat while accounts and usage grow.
Third-Party API Usage Fees	Variable	Model at 5.0% of first-year revenue because usage rises with activity.	Burying API spend inside general software overhead.
Payment Processing Fees	Variable	Apply 3.0% of first-year revenue as sales are collected.	Forgetting that collections create processing expense.
Sales Commissions	Variable	Apply 5.0% of first-year revenue as paid sales close.	Counting commissions as fixed payroll.
Customer Success Manager Payroll	Semi-fixed	Add $75,000 per year for each full-time equivalent added.	Scaling support smoothly instead of in headcount steps.
Annual Marketing Budget	Semi-fixed	Use $120,000 in the first year, then step up by annual plan.	Modeling marketing as pure CAC with no budget ceiling.

How does break-even change as this platform moves from lean launch to base growth and full-scale support?

Scenario table

Here’s the quick math: revenue climbs fast, variable costs fall from 21.0% to 15.8%, and fixed payroll rises, so break-even stays in Month 1 but the cushion gets much wider.

Planning assumptions only; these scenario figures are not a guarantee of future results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$5.53M	$1.16M	$65.08K	79.0%	$4.30M	Month 1 break-even holds, so launch discipline matters.
Base growth case	$32.87M	$6.22M	$124.67K	81.1%	$26.53M	Month 1 break-even still holds, but hiring needs tight control.
Full-scale case	$96.20M	$15.21M	$190.50K	84.2%	$80.80M	Strong cushion supports enterprise service and sales capacity.

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

Stress test

Year 1 has a wide cushion: about $5.53M average monthly revenue against roughly $13.3k break-even revenue. Contribution margin, or revenue left after variable costs, sits near 79%, but trial conversion, API fees, and payroll growth are the weak spots.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$13.3k	$5.52M cushion	Month 1 clears break-even easily, so the base case is not tight.
Revenue shortfall	Average monthly revenue drops 10%.	$13.3k	$4.96M cushion	A 10% revenue drop still leaves a large cushion, but trial conversion needs watching.
Fixed-cost pressure	Fixed monthly spend rises 15%.	$15.3k	$5.52M cushion	Support hiring ahead of paid growth pushes the threshold up.
Margin pressure	Third-party API fees rise enough to cut contribution margin by 5 points, to 74%.	$14.2k	$5.52M cushion	API fees above 5.0% cut the cushion fast.
Combined pressure	Revenue drops 10%, fixed spend rises 15%, and contribution margin falls to 74%.	$16.3k	$4.96M cushion	If revenue, margin, and fixed spend all move against you, the cushion shrinks fastest.

Founder checklist

Don’t scale the $120,000 Year 1 marketing budget or add a Customer Success Manager until the $49, $149, and $399 plans, 5.0% trial start rate, and 12.0% trial-to-paid conversion hold in live demand. Keep Month 1 cash above the $1.092M minimum and separate the $63K setup spend from operating break-even.

1Plan Mix$49 / $149 / $399

Confirm the Year 1 mix really lands near 60% Starter, 30% Growth, and 10% Pro, because pricing mix drives the revenue you need to hit break-even.

2Launch Demand5.0%

Verify that at least 5.0% of acquired users start a free trial before you push more of the $120K marketing budget into the channel.

3Paid Convert12.0%

Check that 12.0% of free trials become paid accounts, because clicks do not cover fixed costs.

4Unit Margin79% CM

Test the 100, 500, and 2,000 transaction levels against the 21% direct-cost load so contribution stays near 79% before fixed expenses.

5Fixed Load$65.1K/mo

Keep the monthly office and payroll stack near $65.1K, and add the Customer Success Manager only when onboarding volume can support that salary.

6Cash Buffer$1.092M

Hold Month 1 cash above the $1.092M minimum and treat the $63K setup spend for servers, laptops, furniture, security, and network hardware as separate from operating break-even.
