Cost classification

Break-even is only reliable when each expense follows the right sales behavior. Put stable monthly bills in the fixed base, and deduct sales-linked costs through contribution margin.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent, $7,500 per month	Fixed	Included in fixed base.	Moving rent with covers understates the monthly sales target.
Business Insurance, $300 per month	Fixed	Included in fixed base.	Leaving it out makes break-even look too easy.
Donut Ingredients, 8% of first-year sales	Variable	Deducted through contribution margin.	Modeling ingredients as fixed overstates margin as volume rises.
Beverage & Other Ingredients, 4% of first-year sales	Variable	Deducted through contribution margin.	Using one flat food rate can hide drink and baked-good mix shifts.
Marketing & Promotions, 4% of first-year sales	Variable	Deducted through contribution margin.	Treating promotions as fixed can overstate contribution margin.
Utilities, $1,200 per month	Semi-variable	Include the base bill in fixed base; deduct usage-driven overage through contribution margin.	Treating utilities as fully variable misses the standing monthly bill.
Cleaning Services, $450 per month	Semi-fixed	Included in fixed base until service frequency steps up.	Treating cleaning as fully variable understates the break-even point.
Barista/FOH Staff, 2.0 FTE in the first year	Semi-fixed	Included in fixed base by planned FTE; step up as covers rise.	Treating payroll as fully variable hides staffing jumps.

How does break-even shift from a lean weekday launch to the Year 1 base plan and the Year 5 full build?

Scenario table

Lean traffic misses break-even fast because rent and core payroll do not flex much. Year 1 is the crossover point, and Year 5 builds a wider cushion as weekly covers and contribution margin rise.

Planning figures only; actual break-even will move with traffic, menu mix, labor, and rent.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean weekday launch	$25.4k	$4.6k	$27.7k	82%	-$6.8k	Too light; it needs weekends or lower overhead.
Base Year 1 plan	$121.6k	$21.9k	$27.7k	82%	$72.3k	Near the break-even line; traffic discipline matters.
Full Year 5 scale	$301.2k	$45.2k	$34.3k	85%	$221.6k	Scale creates a strong cushion even with higher staffing.

What breaks first if weekday traffic softens or costs creep up?

Stress test

The plan has a wide cushion at the modeled base case: about $1.217 million in monthly revenue versus about $405,000 to break even. The pressure points are weak weekday covers, overtime, food waste, discounting, and rent creep before you lock the lease or décor spend.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$405,000	$812,000 cushion	Solid cushion, so small misses do not break the model.
Revenue shortfall	Revenue falls 10% to about $1,095,000.	$405,000	$690,000 cushion	Still well above break-even, but traffic needs to hold.
Fixed-cost pressure	Fixed costs rise by $5,000 a month.	$466,000	$751,000 cushion	Rent or staffing creep eats cushion faster than sales growth.
Margin pressure	Variable expense pressure lifts costs from 18% to 22%, cutting margin to 78%.	$426,000	$791,000 cushion	Food waste and discounting matter, but the model still clears break-even.
Combined pressure	Revenue slips to about $973,000, margin falls to 78%, and fixed costs run at $382,000.	$490,000	$483,000 cushion	Still clears break-even, but weekday demand and labor control need close watch.

Can this themed restaurant clear break-even checks before you sign the lease?

Founder checklist

Only move ahead if weekday and weekend covers, menu pricing, fixed costs, payroll, and cash all match the model. The site is not ready if it cannot support $405K in monthly sales and carry the Month 2 cash floor of $841K.

1Weekday Covers150-250/day

Verify Monday through Thursday demand stays in the 150 to 250 cover range so the lease is tied to real midweek traffic, not hope.

2Weekend Covers350-450/day

Confirm Friday, Saturday, and Sunday can hold 350, 450, and 400 covers, because the weekend volume has to carry the sales plan.

3Menu Price$12 / $16 AOV

Test $12 midweek and $16 weekend average order value, and keep ingredient quotes near 12% of sales so margin does not slip.

4Fixed Costs$10.65K/mo

Lock rent at $7,500 and total operating fixed costs at $10,650 before payroll, since this is the base overhead the store must cover.

5Payroll Ramp$271K Y1

Build staffing around Year 1 payroll of $271K so labor matches the cover forecast without adding dead shifts.

6Cash + Buildout$841K / $154.5K / $405K

Keep the Month 2 cash floor at $841K, fund the $154.5K fit-out and equipment plan, and do not sign the lease unless the site can support at least $405K in monthly sales.
