Restaurant break-even analysis: how many covers until you're actually profitable

Every operator has asked the question. Usually at 2 a.m., staring at a P&L that doesn't add up: how many people actually need to walk through that door before I'm making money?

Most restaurant owners can tell you their food cost percentage. They can quote their labor percentage. Ask them their break-even point and you get a blank stare.

This is the number that matters more than any other metric on your statement. It tells you whether tonight's 62 covers put money in the bank or just kept the lights on for another shift.

Fixed costs: what you pay at zero covers

Before a single guest sits down, you're already writing checks.

Rent on a 1,800-square-foot space in Austin runs anywhere from $4,500 to $7,200 a month depending on the neighborhood. Insurance tacks on $400 to $800. Your general manager is making $55,000 in Nashville or closer to $68,000 in Chicago, and that salary hits the books whether you serve 5 covers or 200.

Then there's the stuff operators forget to write down. POS software subscriptions. Pest control. Music licensing. Trash pickup. Grease trap cleaning. The list is long and invisible until you put it on paper.

For a typical full-service restaurant in a mid-sized US city, monthly fixed costs land somewhere between $15,000 and $25,000.

This is your nut. The number you need to cover before dollar one of profit. Until every cent of this is paid, you are not making money.

Variable costs per cover: where food costing earns its keep

Variable costs move with every plate that leaves the kitchen. They're the numbers you control, at least partially.

Food cost per cover

If your average check is $28 and your food cost runs at 30%, that's $8.40 in ingredients for every guest. But this number is honest only if your recipe costing is sharp. If you're guessing at portion costs, you're guessing at your break-even too. A 3-point error on food cost percentage changes your entire calculation.

Hourly labor per cover

Servers at $2.13 tipped minimum plus line cooks at $16 to $22 an hour in a market like Denver or Phoenix. Take total hourly payroll, divide by cover count, and you have labor per guest. Most full-service restaurants land between $7 and $12 per cover on hourly labor.

Supplies per cover

Linens. To-go containers. Dishwasher chemicals. Napkins. Small dollars individually. Across 200 covers on a Saturday they add up. Budget $1.00 to $2.50 per cover.

💡 ⚡ Your variable cost per cover is only as accurate as your recipe costing. A 3-point miss on food cost percentage cascades through your entire break-even calculation. Cost your recipes first, then plug real numbers into the framework below.

Contribution margin: the number that sets your target

Take your average check and subtract your variable cost per cover. What's left is contribution margin. These are the actual dollars each guest puts toward covering your fixed costs before profit appears.

Average check: $35.

Variable cost: $17.50 (food $10.50 + labor $5.50 + supplies $1.50).

Contribution margin: $17.50 per cover.

Every guest drops $17.50 toward your rent, insurance, and management salaries. Below breakeven, every cover still loses money because fixed costs aren't fully covered. Above it, every cover generates real profit at the contribution margin rate.

The break-even formula, step by step

Three numbers. One division. That's it.

1. Grab your total monthly fixed costs.
2. Calculate your contribution margin per cover.
3. Divide: fixed costs / contribution margin = break-even covers.

The owner who writes this on a napkin knows more about their business than 80% of their competitors.

A real restaurant example with actual numbers

Let's run the numbers for a 60-seat casual dinner restaurant in Nashville, open 6 nights a week.

Monthly fixed costs

• Rent: $6,200
• Insurance: $650
• General manager salary: $4,800
• Utilities (base portion): $900
• Software, subscriptions: $350
• Pest, trash, hood cleaning, misc: $600
• Total: $13,500

Per-cover numbers

• Average check: $32
• Food cost (30%): $9.60
• Hourly labor allocation: $7.00
• Supplies: $1.80
• Variable cost total: $18.40
• Contribution margin: $13.60

Break-even calculation

$13,500 / $13.60 = 993 covers per month.

That's 38 covers per night across a 26-day month. If the restaurant does 55 covers on a Friday, they're above water. If they do 22 covers on a Tuesday, every single check that night runs at a loss once fixed costs are accounted for.
