Cost classification

Break-even works only when monthly overhead and sales-linked expenses are split cleanly. Fixed operating costs include rent, utilities, subscriptions, and scheduled payroll; ingredients, packaging, promotions, and card fees move with revenue, while the $57k opening buildout stays out unless financed.

Expense	Cost	Break-Even Treatment	Common Mistake
Kiosk Rent	Fixed	Use $2,000 per month in operating break-even.	Spreading rent across orders and hiding the true monthly hurdle.
Utilities	Fixed	Use $300 per month, as modeled in the source data.	Treating all power and water as volume-driven.
POS System Subscription	Fixed	Use $50 per month as fixed overhead.	Mixing subscription fees with payment processing fees.
Year 1 Payroll	Fixed	Use scheduled staffing as fixed monthly overhead, about $9.2k per month from $110k annual payroll.	Typing $92k per month instead of the modeled annual salary base.
Ingredients	Variable	Apply 10% of revenue in the first year.	Using a flat dollar amount even when sales rise.
Packaging	Variable	Apply 2% of revenue in the first year.	Forgetting that cups, lids, bags, and wraps follow order volume.
Marketing & Promotions	Variable	Apply 4% of revenue in the first year.	Locking spend as fixed and overstating margin at low sales.
Payment Processing Fees	Variable	Apply 2% of revenue in the first year.	Leaving card fees out of contribution margin.

How does break-even change from a lean kiosk to a full robot coffee shop build?

Scenario table

Break-even moves with traffic, ticket size, and the cost mix. The lean case is basically at zero profit, the base case has room to breathe, and the full case only works if variable costs stay near 14%.

Figures are planning assumptions, not guarantees; actual results will shift with demand, pricing, and cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean kiosk break-even case	$148k	$27k	$121k	82%	$0	Right on the edge; there’s no cushion.
Base Year 1 case	$343k	$62k	$121k	82%	$160k	Healthy cushion; profit covers fixed costs.
Full mature case	$1.245M	$177k	$161k	85.8%	$907k	Strong cushion, but cost control still matters.

What breaks the break-even plan for this robot coffee shop?

Stress test

Here’s the quick math: the base plan has about a $195k monthly cushion over the $148k break-even point. A 20% traffic drop, a $20k fixed-cost bump, or a move from 18% to 23% variable expenses each narrow that buffer fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$148,000	$195,000 cushion	Healthy on paper, but not limitless.
Revenue shortfall	Monthly revenue drops 20% from the Year 1 base.	$148,000	$126,000 cushion	Weak weekday traffic cuts the buffer fast.
Fixed-cost pressure	Monthly fixed costs rise by $20,000.	$172,000	$171,000 cushion	Higher rent or labor eats the cushion.
Margin pressure	Variable expenses rise from 18% to 23%.	$157,000	$186,000 cushion	Ingredient inflation or payment fees push break-even up.
Combined pressure	Revenue drops 20%, fixed costs rise by $20,000, and variable expenses hit 23%.	$204,000	$70,000 cushion	Downtime and slower throughput leave little room.

What should the founder verify before signing the lease and buildout for this automated cafe?

Founder checklist

Don’t lock the site until demand, margin, and cash all match the model. The shop needs about 103 orders a day in Year 1, plus enough reserve cash to survive the Month 2 trough.

1Daily demand103/day

Verify the shop can hold the Year 1 run-rate near 103 orders a day, because the model does not work if traffic stays much lower than break-even.

2Fixed overhead$2.95K/mo

Check that kiosk rent, utilities, insurance, and admin stay near $2.95K a month, since fixed cost gets paid before the first sale.

3Margin mix82% CM

Here’s the quick math: 10% ingredients plus 2% packaging equals 12%, and adding 4% marketing plus 2% processing leaves about 82% contribution margin.

4Staffing load$110K/yr

Lock the Year 1 payroll plan at $110K with 1 owner-manager, 1 lead maker, and 1 sales and service role before adding hours or headcount.

5Cash trough$837K

Confirm reserve cash can cover the $837K minimum in Month 2, because the business burns cash before it reaches the Month 3 break-even point.

6Weekend pull180/150

Verify Saturday demand at 180 orders and Sunday at 150, and write the backup and uptime plan before opening so downtime does not wipe out peak volume.
