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

Cost classification

Your break-even is only reliable when fixed overhead stays separate from contribution margin, meaning sales left after variable costs. Here, rent and core salaries set the hurdle; ingredients, packaging, and flexible labor move with covers.

Expense	Cost	Break-Even Treatment	Common Mistake
Commercial Lease Rent	Fixed	Include $7,500 per month in fixed overhead from Month 1 through Month 60.	Dividing rent by covers and treating it like a per-guest charge.
Utilities	Semi-fixed	Start with $1,200 per month, then adjust only when hours, equipment use, or capacity changes materially.	Modeling every utility dollar as directly tied to each guest.
Internet & Phone	Fixed	Carry $200 per month as stable operating overhead in the monthly break-even model.	Adding it to variable service fees instead of fixed overhead.
Cleaning Services	Semi-fixed	Use $600 per month until traffic or operating days require a higher cleaning schedule.	Assuming cleaning rises smoothly with every cover.
Salaried manager, head service lead, and lead cook	Semi-fixed	Use $147,000 per year as the base management and kitchen leadership layer before hourly staffing changes.	Treating salaried leadership as fully variable labor.
Service, front-of-house, and prep labor	Semi-variable	Use $152,000 per year in the first year, then flex staffing as covers rise by day and year.	Calling all labor fixed and missing the cover-driven scheduling effect.
Food & Beverage Ingredients	Variable	Put ingredients in contribution margin at 10.0% of first-year sales, declining to 8.0% by the fifth year.	Leaving ingredients in overhead and overstating margin per guest.
Packaging & Disposables	Variable	Include disposables at 1.5% of first-year sales, declining to 1.0% by the fifth year.	Ignoring small sales-linked items because each ticket looks minor.

How does break-even shift from a lean launch to a full-service fondue restaurant?

Scenario table

Lean launch has $70,980 of monthly revenue and a $24,162 cushion; base lifts that to $45,698, and full-service reaches $68,485. More covers and bigger checks spread rent and payroll faster, so break-even gets safer.

Planning figures only; actual break-even will move with cover mix, labor hours, and event volume.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean weekday launch	$70,980	$11,002	$35,817	84.5%	$24,162	Works, but weekday softness can squeeze the cushion.
Base weekend mix	$98,475	$14,377	$38,400	85.4%	$45,698	Comfortable cushion if weekend traffic stays steady.
Full-service event mix	$128,050	$17,415	$42,150	86.4%	$68,485	Strong cushion; private events help cover fixed cost fast.

What breaks the break-even plan if traffic softens or costs creep up?

Stress test

The plan has a cushion in the base case, but it narrows fast. A 15% sales dip, $5,000 more fixed cost, or a 5-point rise in variable costs all cut room for error; the combined hit leaves about $7,148.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$46,818	$24,162 cushion	Healthy cushion, but weekday softness shows first.
Revenue shortfall	Sales fall 15% to about $60,333.	$45,168	$15,165 cushion	Traffic drops, but profit still holds.
Fixed-cost increase	Fixed costs rise by $5,000 a month.	$51,818	$19,162 cushion	Rent or staffing creep eats buffer.
Margin pressure	Variable costs rise to 20.5% of sales.	$50,368	$20,612 cushion	Waste or payroll pressure cuts margin.
Combined pressure	Sales fall 15%, variable costs rise to 20.5%, and fixed costs add $5,000.	$53,185	$7,148 cushion	The cushion gets thin fast.

Is this fondue restaurant ready to break even before you sign the lease?

Founder checklist

Don’t sign the lease until the model can clear $42,386 in monthly sales, cover $7,500 rent, and fund the $470,000 capex plus the $558,000 minimum cash need. Year 1 also has to support 735 weekly covers, $299,000 payroll, and enough private events to keep tables full.

1Sales path$42,386/mo

Verify the monthly sales plan clears break-even, because the lease only works if covers turn into enough checks each month.

2Rent load$7,500/mo

Compare $7,500 rent with expected covers before you sign, or the room starts behind on day one.

3Weekly covers735/week

Test whether Year 1 can really hit 735 covers a week across all days, since that is the traffic the model needs from opening month onward.

4Ticket mix$18/$25

Test $18 midweek and $25 weekend tickets, and keep cheese, chocolate, beverages, and disposables near 11.5% COGS so the margin math stays clean.

5Payroll load$299K Y1

Staff against the $299,000 Year 1 payroll, not hope, because the plan already assumes a manager, kitchen lead, baristas, floor staff, and prep coverage.

6Launch cash$1.028M

Hold $470,000 for capex plus the $558,000 minimum cash need, then prove group seating and private event flow before buying furniture and serviceware, because cash bottoms in Month 6 even though break-even is modeled in Month 3.
