Cost classification

Reliable break-even starts with $51,500 in core monthly overhead, then keeps planned first-year seller and buyer acquisition spend at $50,000 per month separate. Blend them, and Month 4 break-even can look cleaner than the cash reality.

Expense	Cost	Break-Even Treatment	Common Mistake
Engineering payroll	Semi-fixed	Include current engineering salaries in core overhead; add new FTE only when staffing steps up.	Spreading future hires evenly across early months.
Community management	Semi-fixed	Include first-year staffing in overhead, then step up as user activity needs more coverage.	Treating moderation as flat while activity rises.
Customer support	Semi-fixed	Model the base team as overhead, with step increases as users, orders, and tickets grow.	Holding support flat after buyer growth accelerates.
Office rent	Fixed	Include $5,000 per month in the $51,500 core monthly overhead.	Linking rent to sales volume.
Legal & Compliance	Fixed	Include $1,500 per month as recurring overhead from Month 1 through Month 60.	Leaving compliance out until a problem appears.
Software Licenses (Platform)	Fixed	Include $2,000 per month in operating overhead, separate from one-time software setup spend.	Double-counting licenses as both recurring and launch spend.
Transaction Processing Fees	Variable	Reduce contribution margin by 2.5% of revenue in the first year.	Putting processing fees inside fixed overhead.
Platform Hosting Costs	Variable	Reduce contribution margin by 3.0% of revenue in the first year.	Treating hosting as flat when usage rises.

How does break-even shift from lean to base to full growth?

Scenario table

Here’s the quick math: as acquisition and support costs rise, break-even jumps from about $61.7k in the lean case to about $122k in base, then to about $799k in full growth. The gap only closes if revenue density improves faster than overhead.

Planning figures only; real results will move with CAC, moderation load, and mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean platform	$61.7k	$10.2k	$51.5k	83.5%	$0	Near break-even, so small CAC or moderation spikes can turn profit negative.
Base platform	$122k	$20.5k	$101.5k	83.2%	$0	Acquisition spend lifts the hurdle, so growth must outrun support load.
Full growth platform	$799k	$100k	$699k	87.5%	$0	Scale works only if seller subs, promotion fees, and commission revenue stay ahead of fixed hiring.

What breaks the break-even plan for this social networking platform?

Stress test

The plan reaches break-even in Month 4, but it’s fragile until paid acquisition turns into retained users. Higher CAC, weaker seller conversion, payroll growth, and faster hosting or moderation spend can push required revenue up fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$122,000	$0 gap	Base case clears break-even at Month 4.
Revenue shortfall	Monetized user revenue runs 15% below plan as retention lags.	$143,500	$21,500 gap	Slow user retention makes paid spend pay back later.
Fixed-cost pressure	Payroll runs 10% above the Year 1 wage plan.	$134,200	$12,200 gap	Payroll growth lifts the monthly floor fast.
Margin pressure	Variable costs take 10 more points of revenue from hosting, ads, and moderation.	$138,700	$16,700 gap	Higher hosting and moderation spend squeezes contribution margin.
Combined pressure	Monetized user revenue is 15% light, payroll is 10% high, and variable costs take 10 more points.	$179,400	$57,400 gap	Higher CAC, weaker seller conversion, and faster hosting growth can break the base case.

What should you verify before you scale hiring and marketing on this platform?

Founder checklist

Before you add engineers, paid acquisition, or moderation headcount, prove the platform can still hold Month 4 break-even. If seller CAC stays near $150, buyer CAC near $10, and cash stays above $641K, the launch math is still believable.

1Seller CAC$150

Verify seller CAC stays near $150 before you release the seller side of the Year 1 budget; if it drifts, the $600K combined marketing plan gets expensive fast.

2Buyer CAC$10

Verify buyer CAC stays near $10 before you scale the buyer side of the Year 1 budget; cheap signups only help if they turn into active users.

3Paid Tiers$19.99 / $4.99

Test seller plans at $19.99, $49.99, and $29.99, plus buyer plans at $4.99 and $9.99; if paid tiers don't convert, the platform leans too hard on ads.

4Take Rate10% take

Confirm the 10% commission line really hits order value and trends toward 8% by Year 5; that's the cleanest check on contribution margin.

5Cash Buffer$641K

Keep at least $641K in cash, because the model's minimum cash lands in Month 5 and the business needs room to absorb launch burn.

6Staff RampMonth 4

Hold hiring to the Month 4 break-even line; if moderation or support tickets rise faster than revenue, delay the senior engineer and other headcount.
