Cost classification

Break-even depends on separating monthly overhead from transaction-driven drains. Bad labels can make the Month 22 break-even look cleaner than the cash reality, especially with paid acquisition and processing fees.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Add $3,500/month to fixed overhead from Month 1 through Month 60.	Reducing rent when order volume is low.
Legal & Accounting Fees	Fixed	Add $1,200/month to the recurring overhead hurdle.	Treating recurring compliance work like a one-time launch bill.
General Software Licenses	Semi-fixed	Start with $800/month, then review as team size and operating tools expand.	Assuming software scales smoothly with revenue.
Payroll	Semi-fixed	Model salaries as hiring steps, not per-order expense; support and engineering headcount rise as scale increases.	Tying payroll to a flat revenue percentage.
Transaction Processing Fees	Variable	Deduct 2.5% of first-year revenue before contribution margin; the rate declines to 2.1% by Year 5.	Using the seller payment processing fee of $0 and missing the COGS fee.
Server Hosting Costs	Variable	Deduct 1.5% of first-year revenue; the rate declines to 1.1% by Year 5.	Treating hosting as fixed because the bill feels technical.
Customer Support Software Subscriptions	Variable	Deduct 1.0% of first-year revenue; the rate declines to 0.6% by Year 5.	Putting all support load into headcount only.
Seller and Buyer Acquisition Marketing	Semi-variable	Budget $150,000 for sellers and $200,000 for buyers in the first year, then test CAC against acquired volume.	Treating paid acquisition as harmless; first-year CAC is $250 per seller and $30 per buyer.

How does break-even change from lean to full traction in a motorcycle parts marketplace?

Scenario table

Break-even moves with seller mix and fixed spend. Lean keeps launch costs tighter but still loses money, base narrows the gap, and full traction has the strongest cushion once more active sellers improve fee income.

Planning assumptions only; actual break-even can shift with seller mix, fees, and headcount.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch control	$885K	$58K	$827K	93.5%	($585K)	Tight launch control only; cushion is thin.
Base paid growth	$1.25M	$76K	$1.18M	93.9%	($153K)	Paid growth narrows the gap, but break-even is still not secure.
Full category depth	$1.71M	$97K	$1.61M	94.3%	$1.03M	More active sellers create a clear cushion past break-even.

What breaks the break-even plan for this motorcycle parts marketplace?

Stress test

Here’s the quick math: the model only reaches break-even in Month 22, so it has little room for slip. Seller CAC above $250, buyer CAC above $30, a 10% revenue miss, higher fees, or a 10% overhead lift can push it off track.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in revenue, fees, or overhead.	$885K	$0 gap	Keep seller CAC under $250 and buyer CAC under $30.
Revenue shortfall	Revenue lands 10% below the $885K target.	$885K	$83K gap	A 10% sales miss leaves almost no buffer.
Fixed-cost pressure	Fixed overhead rises 10% to about $910K.	$972K	$87K gap	A 10% overhead creep adds $87K to the bar.
Margin pressure	Variable load rises from 65% to 85%.	$904K	$19K gap	Higher fees erase most of the cushion.
Combined pressure	Revenue is 10% below target, variable load rises to 85%, and overhead rises 10%.	$978K	$182K gap	Slow onboarding, refund disputes, and support load widen the gap.

What should you verify before scaling ads and hiring in a motorcycle parts marketplace?

Founder checklist

Confirm the supply, checkout, and cost base can hold through Month 22 before you buy growth. Year 1 EBITDA is still negative $585K, so paid spend only makes sense after the core flow works.

1Seller Onboarding600 sellers

Confirm you can onboard about 600 sellers in Year 1 at the assumed $250 CAC before you scale ads, because empty supply makes the marketplace look broken.

2Launch Depth1.5 orders

Keep the first catalog tight until repair shops show 1.5 orders per buyer, because that is the cleanest signal the launch mix can support expansion.

3Take Rate10.0% + $2

Test the 10.0% plus $2 take rate against the 6.5% variable drag, because thin order economics leave little room for ads or exceptions.

4Ops RulesMonth 1

Set fraud review, dispute handling, shipping, and returns rules before the first order, because every manual exception slows payouts and adds support work.

5Runway Load$82.7K/mo

Carry cash for the Year 1 operating load of about $82.7K a month and the $133K minimum draw, or you will run out before the Month 22 break-even point.

6Support Ramp1 to 4 FTE

Delay extra hiring until support can scale from 1 FTE in Year 1 to 4 FTE in Year 5, because volume spikes without coverage will hurt service and repeat use.
