Cost classification

Break-even depends on separating stable monthly overhead from costs that rise with deliveries. If route labor, delivery usage, or support load is misclassified, Month 22 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Warehouse Rent	Fixed	Use $12,500 per month in the break-even base.	Spreading rent per delivery and hiding empty capacity.
Office Rent	Fixed	Use $4,200 per month until the planning range changes.	Linking office rent to customer count without a move.
Technology & Software Subscriptions	Fixed	Use $3,800 per month unless the vendor prices by delivery volume.	Treating all software as variable before checking billing terms.
Water Procurement & Bottling	Variable	Apply 18.0% of revenue in the first year, falling to 14.5% by Year 5.	Modeling water supply as fixed and overstating margin at scale.
Delivery & Logistics	Variable	Apply 8.5% of revenue in the first year, falling to 6.5% by Year 5.	Treating delivery usage as fully fixed when low route density raises each stop.
Payment Processing & Transaction Fees	Variable	Apply 3.2% of revenue in the first year, falling to 2.5% by Year 5.	Leaving card fees below gross margin and overstating contribution.
Customer Service & Support	Semi-variable	Model a usage-linked load at 4.5% of revenue in the first year, declining to 3.2% by Year 5.	Assuming support scales smoothly when missed deliveries create ticket spikes.
Delivery Drivers	Semi-fixed	Add labor in staffing steps as routes fill; driver FTE rises from 3.0 in Year 1 to 16.0 in Year 5.	Treating delivery labor as fully fixed when new routes require hiring blocks.

How does break-even change from lean launch routes to a full delivery network?

Scenario table

As routes scale, variable costs fall as a share of sales, so the CM ratio rises from 60.5% to 69.8%. Still, payroll and marketing lift fixed costs, so break-even revenue climbs from $1.487M in lean to $3.473M in full.

Planning assumptions only; actual results will move with route density, payroll, and marketing spend.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch routes	$423K	$167K	$899K	60.5%	-$643K	Loss phase; revenue is still well below break-even.
Base scaled routes	$2,879K	$959K	$1,604K	66.7%	$315K	Clear break-even with a modest profit cushion.
Full mature route network	$6,133K	$1,852K	$2,424K	69.8%	$1,857K	Strong cushion, but overhead still needs close control.

What breaks the break-even plan if route fill weakens or costs rise?

Stress test

The plan is most exposed to weak route fill and small cost creep. At a 60.5% contribution margin, a 1-point margin slip or a $1,000 monthly overhead bump moves break-even fast, and the Year 1 EBITDA loss of $643K leaves little cushion.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.488M	$1.064M gap	Year 1 still sits far below break-even.
Revenue shortfall	Year 1 revenue runs 10% below plan.	$1.488M	$1.106M gap	Weak route fill widens the cash hole fast.
Fixed-cost pressure	Monthly overhead rises by $1,000.	$1.508M	$1.084M gap	Every extra $1K a month adds about $20K.
Margin pressure	Contribution margin drops to 59.5%.	$1.511M	$1.087M gap	Higher water, delivery, or support costs move break-even up.
Combined pressure	Revenue runs 10% low, margin falls to 59.5%, and overhead rises by $1,000 a month.	$1.531M	$1.149M gap	This can push the plan past Month 22 and strain Month 28 cash.

What should you verify before locking the warehouse and fleet?

Founder checklist

Test the first-year account mix, route load, and cash burn against break-even before you lock in rent, drivers, or fleet spend. This model reaches breakeven in Month 22, and minimum cash drops to -$736K in Month 28.

1Demand proof$68/mo

Verify the Year 1 mix plus 35% dispenser rental attachment still gets you to about $68 per active account each month, or break-even slips fast.

2Margin check60.5% CM

Check Year 1 variable costs before launch; water procurement, delivery, dispenser upkeep, fees, support, and testing take 39.5% of revenue, so about 60.5% must cover fixed costs.

3Fixed burn$74.9K/mo

Confirm you can carry roughly $74.9K a month in fixed rent, software, insurance, utilities, and wages before you add more space or heads.

4Route density3 drivers

Map stop density before you commit to 3 delivery drivers, because thin routes push delivery cost up and slow the move to break-even.

5Cash runway-$736K

Protect cash reserves because minimum cash falls to -$736K in Month 28, so any delay in onboarding or collections makes the gap worse.

6Capex gate$305K

Stage the first $305K of vehicle fleet and dispenser inventory spend only after signed accounts can justify the launch load and keep Year 1 marketing inside the $180K budget.
