Cost classification

Break-even gets unreliable when sales-linked items are treated like rent, or staffing is treated like per-order labor. Use the right bucket so required covers reflect how cash actually moves.

Expense	Cost	Break-Even Treatment	Common Mistake
Food & Beverage Inventory	Variable	Model at 10% of first-year sales, then lower to 8% by Year 5 as purchasing improves.	Treating inventory like rent-like overhead instead of tying it to sales volume.
Merchandise Cost	Variable	Model at 2% of first-year sales, with the percentage declining to 1.5% by Year 5.	Ignoring the margin drag when merchandise mix grows from 10% to 12% of sales.
Animal Care Supplies	Variable	Model at 3% of sales in Year 1, falling to 2.5% by Year 5.	Burying supplies in general overhead and hiding true per-cover economics.
Marketing & Reservation Fees	Variable	Model at 2% of sales in Year 1, because booking-linked fees should rise with customer volume.	Treating booking fees as fully fixed when reservations scale with traffic.
Rent	Fixed	Include $10,000 per month before calculating how many covers are needed to clear overhead.	Dividing rent by covers too early and masking the monthly cash obligation.
Utilities	Semi-variable	Start with the modeled $2,000 per month, then test pressure from longer hours and higher kitchen use.	Assuming usage never changes as weekly covers rise from 570 in Year 1 to 1,140 in Year 5.
Cleaning & Maintenance	Semi-variable	Start with the modeled $1,000 per month, then flex for traffic, lounge wear, and food-service cleanup.	Keeping it flat even when customer count doubles across the forecast.
Payroll Roles	Semi-fixed	Use Year 1 wages of $280,000 per year, or about $23,333 per month, then step up staffing as volume grows.	Treating all labor as per-order labor instead of planned staffing blocks.

How does break-even change from lean launch to full-scale restaurant operations?

Scenario table

Break-even moves up as the model shifts from lean launch traffic to base staffing and then full capacity. The core model still reaches breakeven in Month 3, but cash bottoms at $776k in Month 2 from startup spend.

Planning cases only; these figures show modeled break-even assumptions, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$795k	$135k	$393k	83%	$267k	Launch demand clears break-even, but cushion is still thin.
Base scale case	$1.35M	$207k	$462k	84.6%	$678k	This is the core test of normal staffing and steady traffic.
Full capacity case	$1.94M	$261k	$526k	86.5%	$1.15M	Full build gives the widest cushion, if labor stays tight.

What breaks the restaurant’s break-even plan?

Stress test

The plan clears break-even, but the cushion narrows fast if weekday covers lag, weekends soften, or costs rise before traffic is proven. A 10% sales miss cuts the cushion from about $321k to about $242k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$474k	$321k cushion	Sales sit well above break-even.
Revenue shortfall	Monthly sales fall 10% to about $716k.	$474k	$242k cushion	Lower traffic still clears fixed costs, but the buffer shrinks.
Fixed-cost pressure	Fixed costs rise by $1,000 per month.	$475k	$320k cushion	Even small overhead drift trims cushion right away.
Margin pressure	Variable expenses rise 1 point to 18%.	$479k	$316k cushion	Food, supply, or fee pressure pushes break-even up.
Combined pressure	Sales fall 10%, fixed costs rise $1,000, and variable expenses rise 1 point.	$481k	$235k cushion	Traffic and cost drift together cut the buffer fast.

Can this restaurant hit break-even before you sign the lease?

Founder checklist

Test the model against the Month 3 break-even point before you commit to the lease, full staffing, or buildout. The space, traffic, cash, and launch setup all have to support about $473K in monthly sales without breaking the $776K cash floor.

1Sales Test$473K/mo

Verify the lease, layout, and seat count can support about $473K in monthly sales, since the model reaches break-even in Month 3.

2Traffic Proof570/wk

Check Year 1 traffic at 570 weekly covers and make sure midweek $28 and weekend $35 average order values actually hold.

3Direct Margin10% / 2%

Lock supplier quotes before opening inventory so food and beverage inventory stays near 10% and merchandise cost near 2%.

4Staffing Ramp$280K/yr

Map payroll before you hire the full team, because Year 1 staffing runs about $280K and the extra FTEs only work if weekend demand shows up.

5Cash Cushion$776K

Hold enough cash to survive the Month 2 low, when minimum cash bottoms near $776K, so the business can reach Month 3 breakeven.

6Launch StackMonth 3-6

Do not scale marketing until the reservation flow and POS are live and trackable, because the opening funnel has to be measurable first.
