Cost classification

Break-even is reliable only when fixed overhead stays separate from fees that rise with transactions and user growth. In the first year, treat the 4% screening fee and 3% processing fee as deductions before contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent, $4,000/month	Fixed	Include in monthly overhead across the active planning range.	Tying rent to sign-ups or paid users.
Utilities, $800/month	Semi-variable	Model a base load, then add usage movement as support activity grows.	Ignoring growth in operating activity.
Software Subscriptions, $3,000/month	Semi-fixed	Hold flat until tools, seats, or service tiers expand.	Treating all tooling as purely variable.
Professional Fees Legal Accounting, $2,500/month	Fixed	Include as recurring compliance and accounting overhead.	Burying legal work in one-time setup only.
Background Check Provider Fees, 4% in first year	Variable	Deduct before contribution margin because it moves with screened activity.	Calling screening free in the model.
Payment Processing Costs, 3% in first year	Variable	Deduct per transaction before calculating break-even revenue needs.	Calculating break-even on gross revenue.
Customer Support, $80,000 salary at 1.0 FTE in first year	Semi-fixed	Add capacity in staffing steps as user volume and tickets rise.	Hiring ahead of ticket volume.
Combined Marketing Budgets, $900,000 in first year	Semi-variable	Tie spend to acquisition cost targets and conversion proof.	Spending before CAC payback is visible.

How does break-even shift from a lean city launch to a full metro rollout for a roommate matching service?

Scenario table

Break-even gets easier only when monthly revenue grows faster than the fixed load. At about $183k to $185k a month, the launch case is thin; at about $581k a month, the larger rollout has a much wider cushion.

Planning assumptions only. These figures are model inputs, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean city launch	$183k	$13k	$170k	93%	$0	Very thin cushion; one weak month can miss break-even.
Base Year 1 launch	$185k	$13k	$170k	93%	$2k	Breakeven lands in Month 7, but the cushion stays small.
Expanded metro rollout	$581k	$36k	$237k	94%	$308k	Strong cushion, if membership volume supports the mix.

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

Stress test

The base plan has only a small cushion: about $185,000 a month in revenue against about $170,000 of fixed cost, with 7% variable expense and roughly $2,000 EBITDA. A 10% revenue miss or 10% higher fixed load turns that cushion into a gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$183,000	$2,000 cushion	Only a thin cushion; Month 7 is the first break-even point.
Revenue shortfall	Revenue falls 10% to about $167,000 a month.	$183,000	$15,000 gap	Lower sign-up conversion would push EBITDA negative.
Fixed-cost pressure	Fixed costs rise 10% to about $187,000 a month.	$201,000	$15,000 gap	Overhead creep quickly eats the current cushion.
Margin pressure	Variable expenses rise from 7% to 12%, cutting margin to 88%.	$194,000	$9,000 gap	Seller CAC above $60 or buyer CAC above $50 would squeeze the model.
Combined pressure	Revenue is down 10%, fixed costs are up 10%, and margin slips to 88%.	$213,000	$46,000 gap	Scaling ad spend before paid conversion is proven creates a material monthly gap.

Can you prove roommate matching works before you commit to the platform build and ad spend?

Founder checklist

Before you lock in the platform build, paid acquisition, or city expansion, test whether both sides will pay the listed monthly fees and whether the cash plan can survive the Month 9 low point. The model only works if demand, CAC, staffing, and launch spend all line up.

1Seller pricing$25 / $15 / $10

Validate that landlords, subletters, and coops will pay those monthly fees before you scale, because the seller side has to carry real demand.

2Buyer pricing$10 / $19 / $24

Test students, pros, and families at those price points first, because buyer subscription take-up has to hold for the match funnel to work.

3Promo fee$20 / $0 commission

Prove the $20 promotion fee gets used enough to matter, because the model assumes no commission revenue at all.

4Unit margin7% → 3.5%

Keep background checks and payment processing near 7% of order value in Year 1 and 3.5% by Year 5, or the contribution buffer won't cover fixed costs cleanly.

5Payroll load$855K / year

Keep support hiring tied to real volume, because first-year wages are already $855K, fixed overhead adds $13K a month, and customer support scales from 1 FTE to 5 FTE.

6Cash runway-$323K Month 9

Keep the $1.16M build-out separate from monthly break-even and hold off on new-city expansion until the Month 7 break-even and 20-month payback path are visible, because minimum cash still dips to negative $323K in Month 9.
