Cost classification

Break-even gets shaky when fixed rent, variable ingredients, and step-up staffing are lumped together. Classify each expense first, then the Month 3 break-even target has a cleaner link to sales volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Kitchen Rent	Fixed	Use $4,000 per month as overhead that must be covered before profit.	Treating rent like it falls on slow weekdays.
Business Licenses & Permits	Fixed	Include $150 per month in the fixed break-even base.	Leaving permits out because they feel small.
Food Ingredients	Variable	Apply 8.0% of first-year revenue, then lower percentages by year as modeled.	Using a flat dollar amount instead of sales-linked usage.
Disposable Supplies	Variable	Apply 2.0% of first-year revenue for trays, cups, napkins, and similar order-linked items.	Counting supplies as fixed even when every order uses them.
Event Staff Wages	Variable	Apply 6.0% of first-year revenue because staffing flexes with bookings and volume.	Putting event labor in payroll overhead and hiding margin pressure.
Fuel & Vehicle Maintenance	Variable	Apply 2.0% of first-year revenue since travel and service runs rise with sales activity.	Ignoring delivery distance and treating every job as equal.
Utilities	Semi-variable	Start with the $700 monthly plan amount, but expect usage to swing with cooking volume.	Modeling utilities as fully fixed during busy periods.
Sales & Event Coordinator	Semi-fixed	Model the role as a staffing step, moving from 0.5 FTE in the first year to 0.8 FTE in the second year.	Putting salaried payroll outside break-even even though sales must cover it.

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

Scenario table

Higher traffic and a bigger ticket lift revenue faster than fixed costs, so the cushion widens as the kiosk scales. The full setup is strongest because contribution margin stays above 80% while overhead grows more slowly than sales.

Planning figures only; actual results will move with traffic, pricing, and cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 kiosk	$633k	$114k	$268k	82.0%	$251k	Above break-even, but the cushion is thin.
Base Year 2 kiosk	$1,436k	$250k	$300k	82.6%	$886k	Clear break-even cushion; profit grows fast.
Full Year 3 kiosk	$2,795k	$464k	$343k	83.4%	$1,988k	Strong cushion; break-even risk is low.

What pushes this fry kiosk past break-even?

Stress test

Baseline break-even is about $327k, so the plan has room at current volume. But weaker traffic, a jump to $343k in fixed costs, or an 18.0% variable load can shrink that cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$327k	$1.109M cushion	Base revenue covers break-even with room to spare.
Revenue shortfall	Traffic falls to $633k per month.	$327k	$306k cushion	Lower weekday and weekend traffic narrows the cushion fast.
Fixed-cost increase	Fixed costs rise from $268k to $343k.	$411k	$1.025M cushion	Staffing expansion pushes break-even higher.
Margin pressure	Variable expenses rise from 16.6% to 18.0% of revenue.	$418k	$1.018M cushion	Small cost drift raises the sales needed to stay even.
Combined pressure	Traffic falls to $633k, fixed costs rise to $343k, and variable expenses rise to 18.0%.	$418k	$215k cushion	All three hits still clear break-even, but the cushion is thin.

Can this french fry kiosk hit break-even before you commit to the site and equipment?

Founder checklist

Don’t sign the lease or buy the gear until the kiosk can support 200 covers a week, hold the $60 midweek and $80 weekend ticket, and carry the Month 3 break-even load. If those inputs wobble, the math moves fast.

1Demand Proof200/wk | $60/$80

Verify the site can deliver Year 1 traffic and pricing before you commit, because break-even only works if those covers and ticket sizes are real.

2Overhead Base$6.15K/mo

Keep rent, utilities, and other fixed overhead near $6,150 a month before salaried payroll, or the kiosk needs much more volume to cover the base.

3Labor Load18% var | $20.6K/mo

Check that menu costs and Year 1 wages stay near the model, because the 18% variable load and $20,625 monthly payroll set how much cash is left for fixed costs.

4Peak Capacity60/120 covers

Test the fry station and crew against 60 Saturday covers in Year 1 and 120 in Year 2 so peak-day demand does not get capped by service speed.

5Supply LockPrelaunch

Lock potatoes, oil, packaging, and disposables before launch, because supply gaps or price spikes hit both service and margin right away.

6Cash Buffer$253K capex | $812K cash

Budget for the $253,000 launch capex and still hold the modeled $812,000 minimum cash in Month 2, or the concept can break before sales settle.
