Which restaurant expenses are fixed, and which move with sales?

Cost classification

Break-even only works when stable monthly bills stay fixed and sales-linked costs move with revenue. Keep one-time build-out and equipment out of monthly operating break-even math.

Expense	Cost	Break-Even Treatment	Common Mistake
Rent & CAM	Fixed	Use $12,000 per month in the fixed-cost base.	Spreading sales changes across rent when the lease is stable.
Utilities	Fixed	Use $1,500 per month as fixed in this model.	Treating it as usage-based without a metered usage driver.
Point-of-sale (POS) System & Software	Fixed	Use $300 per month in fixed overhead.	Mixing monthly software with one-time hardware installation.
Cleaning & Maintenance Services	Fixed	Use $1,000 per month as a recurring operating cost.	Linking the full charge to covers without a variable contract.
Salaried Roles	Fixed	Use first-year salaries of $327,500, about $27,292 per month.	Calling base staffing variable before headcount changes are modeled.
Food Ingredients	Variable	Use 7.0% of revenue in the first year.	Putting ingredients in fixed overhead and understating break-even volume.
Beverage Ingredients	Variable	Use 8.0% of revenue in the first year.	Using one blended food percentage and losing drink-margin detail.
Credit Card Processing Fees	Variable	Use 2.5% of revenue in the first year.	Budgeting it as a flat monthly fee instead of sales-linked.

How does break-even move from a lean opening to base growth and full-capacity service for this eco-friendly restaurant?

Scenario table

Traffic grows fast across the three cases, while variable costs fall from 19.5% of sales in Year 1 to 16.5% in Year 5. That lifts the CM ratio, but staffing also pushes fixed costs higher, so break-even still needs close watch.

Planning assumptions only; actual traffic, labor, and ingredient costs can move these results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean opening case	$56.2K	$11.0K	$43.5K	80.5%	$1.8K	Barely above break-even, so lease terms matter.
Base growth case	$94.7K	$17.9K	$46.7K	81.1%	$30.1K	Comfortable cushion, so this is the hiring pace check.
Full-capacity service case	$311.5K	$51.4K	$55.4K	83.5%	$204.7K	Strong cushion, but seating and kitchen load must hold.

What breaks the break-even plan if weekday traffic slows or costs rise?

Stress test

Year 2 clears break-even by a healthy margin, but the buffer depends on steady weekday traffic and tight cost control. Local ingredient inflation, utility spikes, and labor overages are the main ways this plan slips toward break-even.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$576K	$371K cushion	Year 2 revenue stays above break-even.
Revenue shortfall	Year 2 revenue falls 10% to about $853K.	$576K	$277K cushion	Slower weekday traffic still leaves room, but less of it.
Fixed-cost pressure	Fixed costs rise by $5K.	$638K	$309K cushion	Rent, utilities, or staffing creep tightens the floor.
Margin pressure	Variable expenses rise 5 points, lowering contribution margin to 76.1%.	$614K	$333K cushion	Food inflation or waste can push break-even higher fast.
Combined pressure	Revenue falls 10%, margin drops 5 points, and fixed costs rise $5K.	$680K	$173K cushion	Thin buffer if traffic softens and costs move up together.

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

Founder checklist

Test the lease, menu mix, and staffing plan against the model before you commit. If the cover counts, check sizes, or cash cushion slip, breakeven stays beyond Month 14.

1Lease Load$16.2K/mo

Confirm rent, CAM, utilities, insurance, software, cleaning, security, and accounting fit inside the fixed monthly load before any lease deposit.

2Ingredient Cost15.0%

Verify supplier quotes hold food at 7.0% and beverage ingredients at 8.0% of sales, because that is the model’s ingredient cost assumption.

3Payroll Ramp$327.5K/yr

Check the Year 1 staffing plan against about $27.3K a month in wages before you add any extra roles.

4Cover Plan235/week

Validate the day mix of 10 Monday covers, 15 Tuesday, 20 Wednesday, 30 Thursday, 50 Friday, 70 Saturday, and 40 Sunday before you lock the space.

5Check Size$45 / $60

Confirm guests will spend about $45 midweek and $60 on weekends, or the weekly cover plan will not clear the revenue needed for breakeven.

6Cash Cushion$277K + $582K

Treat build-out, equipment, furniture, hardware, signage, security, and opening stock as upfront cash, and keep enough runway for the Month 13 cash low.
