Cost classification

Classify recurring spend before running break-even: fixed payroll and overhead set the monthly hurdle, while fees move with revenue. Keep the $70k hardware and setup spend in cash runway, not EBITDA break-even.

Expense	Cost	Break-Even Treatment	Common Mistake
Engineering payroll	Fixed	Include in the monthly operating base; first year has 2.0 full-time engineers at $130,000 each.	Treating core build payroll as one-time launch spend.
Office rent, retainers, software, insurance, utilities	Fixed	Use $12,000/month from Month 1 through Month 60.	Spreading rent and retainers as a revenue percentage.
Cloud Infrastructure & Hosting	Variable	Model as 8% of first-year revenue, falling to 5.5% by mature year.	Ignoring hosting load as transactions and customers rise.
Payment Processing Fees	Variable	Model as 4% of first-year revenue, then 3% by mature year.	Counting subscription revenue but missing payment fees.
Sales Commissions	Variable	Model at 5% of revenue across all forecast years.	Putting commissions into fixed payroll instead of sales-linked expense.
Customer Support Outsourcing	Variable	Model at 3% of first-year revenue, easing to 2% as scale improves.	Keeping support flat while active customers and transactions grow.
Marketing budget	Semi-fixed	Use $120,000 in the first year, or $10,000/month, as planned acquisition spend.	Treating CAC as pure variable spend with no budget ceiling.
Customer Success Manager payroll	Semi-fixed	Add headcount in steps: 0.0 FTE in first year, then 1.0 FTE from Year 2.	Loading post-launch success hiring into Month 1 break-even.

How does break-even shift from a lean MVP to a full marketplace launch?

Scenario table

Break-even gets easier as revenue scales faster than support and staffing costs. Lean is for validation, base matches the model’s Month 9 break-even, and full launch gives the widest cushion.

Planning assumptions only; actual break-even will move with pricing, mix, and hiring pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean marketplace MVP	$84.3k	$16.9k	$78.3k	80.0%	-$10.8k	Best for validation; cushion is thin.
Base marketplace growth plan	$259.3k	$49.3k	$117.7k	81.0%	$92.3k	Tracks the Month 9 break-even signal.
Full marketplace launch	$2.22M	$344.5k	$304.2k	84.5%	$1.57M	Strong cushion once scale is in place.

What breaks the break-even plan for this marketplace platform?

Stress test

Year 1 is close to break-even, but the cushion is thin. If revenue slips, marketing resets higher, or cloud and support fees creep up, the Month 9 cover point gets harder to hold.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$884k/month	$41k gap	Year 1 revenue sits just below cover.
Revenue shortfall	Year 1 average revenue slips 10% to $759k/month.	$884k/month	$125k gap	A small top-line miss turns the plan from tight to off-track.
Fixed-cost pressure	Fixed spend rises by about $108k/month with the Year 2 marketing run rate.	$1.020M/month	$177k gap	Higher overhead pushes the cover point past Year 1 revenue.
Margin pressure	Variable expenses rise from 20% to 21% of revenue.	$896k/month	$53k gap	One point of fee creep is enough to widen the gap.
Combined pressure	Fixed spend rises by $108k/month and variable expenses move to 21%.	$1.033M/month	$190k gap	This downside case makes Month 9 break-even hard to hold.

Founder checklist

Do not lock in heavy hiring or paid spend until the $149, $399, and $1,200 monthly plans, the one-time setup fees, and the trial funnel all hold in live tests. Break-even lands in Month 9, so the first months must protect the $690k cash need before Month 8.

1Price Test$149 / $399 / $1,200

Sell the three monthly plans at live prices and confirm the first-year mix of 60%, 30%, and 10% holds, because break-even depends on the Starter plan not carrying the whole base.

2Setup Fees$499 / $2,500

Check that Growth and Enterprise buyers will pay the setup fees, since weak one-time fees slow payback and make the launch month more cash hungry.

3Trial Funnel12% / 15%

Watch whether 12% of prospects start a free trial and at least 15% convert to paid, or the funnel will not feed the revenue plan.

4CAC Check$450 CAC

Keep customer acquisition cost near the $450 Year 1 assumption, because higher spend would cut margin and make paid growth harder to sustain.

5Ops Ramp50 / 250 / 1,500

Make sure moderation, billing, and support can handle 50, 250, and 1,500 transactions per active customer without a hiring jump, or traffic will outpace service.

6Runway Guard$60.8K/mo | 80% CM | $690K

Verify the Year 1 fixed load is about $60.8K a month and the model still holds near 80% contribution margin, then keep cash above the $690k need through Month 8 so Month 9 break-even stays real.
