Cost classification

Your break-even is only reliable if fixed overhead stays separate from revenue-linked costs. Here, the first-year base load is $51,000/month before variable fees: $6,000 fixed overhead plus $45,000 payroll.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent, software licenses, utilities, insurance, legal and accounting, supplies, and fixed content retainer	Fixed	Carry $6,000/month as baseline overhead in the first year.	Loading $217,000 of launch capex into monthly break-even overhead.
Payroll for CEO, engineering, sales, account, operations, and marketing roles	Semi-fixed	Model $45,000/month in the first year, then step up with the FTE plan.	Treating all wages as a percent of revenue.
Seller and buyer acquisition marketing budgets	Semi-fixed	Use $80,000/year, or about $6,667/month, for first-year planned acquisition spend.	Using CAC alone and missing the actual budget ceiling.
Third-party installation and maintenance	Variable	Apply 8.0% of revenue in the first year, falling to 6.0% by the fifth year.	Modeling installation support as fixed even as screen activity grows.
Cloud hosting and platform infrastructure	Variable	Apply 4.0% of revenue in the first year, falling to 3.0% by the fifth year.	Holding hosting flat while advertisers, venues, and ad delivery rise.
Sales team commissions	Variable	Apply 5.0% of revenue in the first year, falling to 4.0% by the fifth year.	Mixing sales base salaries into commission expense.
Payment processing fees	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by the fifth year.	Forgetting fees on both subscriptions and ad order payments.
Venue revenue share, if contracted	Variable	Tie the payout to ad revenue only when venue contracts require revenue sharing.	Hard-coding revenue share as rent instead of sales-linked payout.

How do lean, base, and full rollout scenarios change break-even for indoor digital billboards?

Scenario table

Break-even moves with screen count, ad inventory sold, and pricing, so the same Year 1 cost base can look red, flat, or profitable. Lean stays below break-even, base sits near it, and full adds a small cushion.

Planning assumptions only; screen count, ad inventory sold, and fill rate are editable and do not guarantee results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean screen rollout	$53,700	$10,500	$57,667	80.5%	-$14,467	Still below break-even, so occupancy has to climb fast.
Base case	$71,600	$14,000	$57,667	80.5%	-$67	Near break-even, so small fill swings matter.
Full screen rollout	$89,500	$17,500	$57,667	80.5%	$14,333	Creates a cushion, but weak occupancy can still wipe it out.

What breaks the break-even plan for indoor digital billboards?

Stress test

The base plan clears break-even at about $71,600 a month, but it has little cushion. A 20% sales miss, a 10% jump in fixed overhead, or a five-point margin hit can all push the model into a gap, and the combined shock drives about a $20,100 monthly loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; costs and sales stay at plan.	$71,600	$0 gap	No cushion, so any miss turns into red ink.
Revenue shortfall	Monthly sales run 20% below the base break-even level.	$71,600	$14,300 gap	Slow buyer acquisition leaves the model short on cash.
Fixed-cost pressure	Fixed overhead rises 10% to about $63,400 a month.	$78,800	$7,200 gap	Venue payout pressure or staffing can move breakeven fast.
Margin pressure	Variable expense rate rises five points to 24.5% of revenue.	$76,400	$4,800 gap	Repair spikes or higher servicing costs eat margin.
Combined pressure	Sales stay 20% below plan while variable costs rise to 24.5% and fixed overhead rises 10%.	$84,000	$20,100 gap	This is the cash burn case, and it can force cuts fast.

Before you buy the first screen package, what should you verify?

Founder checklist

Commit only after the first venues are signed, install access is clear, and advertisers look buyable at the Year 1 CACs. The model does not reach break-even until Month 27, and cash bottoms at -$270,000 in Month 26, so early proof matters.

1Venue access$50.0K

Verify signed venue access terms before ordering the $50,000 initial screen package; without locked locations, the first capital spend can sit idle.

2Mounting access$10.0K

Confirm mounting permissions, power, connectivity, hours, and maintenance access before spending the $10,000 installation equipment budget; missing any one of them pushes break-even out.

3Price inventory80.5% CM

Verify ad pricing still leaves enough after 8.0% installation and maintenance, 4.0% hosting, 5.0% sales commissions, and 2.5% payment fees; that cost stack keeps contribution margin near 80.5%.

4Buyer CAC$300 CAC

Test advertiser demand against the Year 1 buyer CAC of $300, and confirm who sells local, regional, and national accounts; if leads cost more, the pipeline will not carry growth.

5Sales load$57.7K/mo

Delay fixed hiring if the pipeline cannot support the $57,667 monthly burden from rent, software, utilities, insurance, legal, supplies, content retainer, and wages; payroll can outrun revenue fast.

6Cash floor-$270K

Track cash weekly because minimum cash reaches -$270,000 in Month 26; if reserves are thinner than that gap, you may run out before the Month 27 break-even date.
