Cost classification

Break-even gets cleaner when fixed overhead is separated from booking-driven spend. In this model, the Month 30 break-even depends on not treating paid acquisition, payment fees, support, and risk checks as flat overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $2,500 per month as baseline overhead from Month 1 through Month 60.	Scaling rent with bookings when the model shows a flat monthly amount.
Software Subscriptions	Fixed	Use $800 per month as recurring overhead for customer and project systems.	Dropping it below the contribution line as if it varies by order.
Legal Retainer	Fixed	Use $1,000 per month as fixed operating overhead across the planning range.	Treating routine legal coverage like one-time setup spend.
Core Payroll	Semi-fixed	Model salaries in FTE steps as the team expands by year, not per booking.	Assuming payroll rises smoothly with sales instead of capacity jumps.
Annual Marketing Budget	Semi-variable	Tie spend to seller CAC and buyer CAC, then test whether volume supports payback.	Treating paid acquisition as pure fixed overhead.
Payment Processing Fees	Variable	Apply 2.5% in the first year, falling to 2.1% by the fifth year.	Leaving processing fees out of contribution margin.
Insurance Claims & Background Checks	Variable	Apply 1.5% in the first year, falling to 1.1% by the fifth year.	Ignoring fraud review and claims as bookings rise.
Customer Support Transaction-Related	Variable	Apply 2.0% in the first year, falling to 1.6% by the fifth year.	Counting all support as fixed even when ticket load follows transactions.

How does break-even shift from a lean launch to a base case and a full-scale rental marketplace?

Scenario table

Break-even moves with the margin and the cost base. Lean stays in the red, base lands at neutral, and full turns positive only after higher volume absorbs a much larger fixed load.

Planning assumptions only; results are not guaranteed.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch ramp	$159K	$143K	$55K	10%	-$40K	Still well below break-even.
Base break-even case	$521K	$47K	$474K	91%	$0	Neutral operating profit.
Full Year 3 scale case	$1.07M	$878K	$178K	18%	$15K	Positive cushion, but only after liquidity improves.

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

Stress test

The plan clears break-even at about $521K of annual revenue, but it has little room for misses. A 20% revenue drop, $10K more monthly overhead, or margin pressure can push the model back into a six-figure gap fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$521K	$0 gap	No cushion; any miss turns negative.
Revenue shortfall	Revenue lands 20% below plan, at about $417K.	$521K	$95K gap	A modest top-line miss wipes out the margin.
Fixed-cost pressure	Add $10K in monthly overhead.	$631K	$110K gap	Overhead pushes break-even out fast.
Margin pressure	Variable expenses rise from 90% to 120% of plan.	$537K	$16K gap	Fees, refunds, and support load eat the spread.
Combined pressure	Revenue falls to $417K, variable expenses rise to 120%, and fixed overhead rises to $574K.	$624K	$207K gap	CAC, fraud, and support costs can break liquidity early.

Before you lock the $150K platform build, what has this rental marketplace got to prove first?

Founder checklist

Don’t greenlight the build, hiring, or ad spend until seller CAC holds near $250 and buyer CAC near $50, the Month 29 cash trough is covered, and the plan still reaches break-even by Month 30. If those three do not hold, the launch is too heavy.

1Supply proof$250 / $50 CAC

Confirm early sellers and buyers can be acquired near the target CAC before you spend the $150K build budget, because a marketplace without both sides stalls fast.

2Fixed loadY1 EBITDA -$474K

Year 1 EBITDA is -$474K, so keep fixed spend lean until usage rises enough to absorb that burn.

3Margin test1% + $2

The Year 1 fee stack leaves about a 1% spread plus the $2 fixed commission after 2.5% payment fees, 1.5% claims and checks, 3.0% hosting, and 2.0% transaction support, so weak AOV can erase the margin.

4Staffing rampMonth 13 / 25

Add the Product Manager in Month 13 and the UI/UX Designer in Month 25 only when transaction volume proves the need, or support and product costs will outrun revenue.

5Cash trough-$461K

The model bottoms out at -$461K in Month 29, so you need reserve cash to survive that trough before you add nicer tools or extra hires.

6Launch demandMonth 30

Do not scale the Year 1 seller budget of $50K or the buyer budget of $100K until the path to Month 30 break-even is clear, or you will spend ahead of demand.
