How to Calculate a Restaurant's Break-Even Point (with Formula and Worked Example)

I’ve spent over fifteen years walking into other people’s kitchens with a scale, a spreadsheet, and a promise not to judge. In most of the restaurants I’ve audited, the owner invoiced every month and honestly couldn’t tell if they had made or lost money until the quarterly tax return landed. It’s staggering, but it happens. You work 14-hour days, pack the dining room on Fridays, your plate costing shows a spotless 30% food cost… and at the end of the year, the profit-and-loss statement is red. Why? Because billing a lot isn’t the same as being profitable. There’s an invisible line, a number that separates desperation from peace of mind, and 80% of the restaurateurs I work with don’t know it: the break-even point. In this article, you’ll finally understand what it is, how to calculate it to the cent—with formulas, worked examples, and common pitfalls—and, above all, how to stop looking at it once a month and manage it day by day, service by service, which is what truly changes a business. Let’s get to it.

What Is a Restaurant’s Break-Even Point (and Why It’s the Same as Break-Even Threshold, Dead Point, and Break-Even)

Let’s be crystal clear from the start: break-even point, break-even threshold, dead point, and break-even all mean exactly the same thing. Four names for a single idea: the sales figure—in euros or covers—that matches all costs and leaves zero profit. You neither gain nor lose. Beyond that floor, every euro you sell above it starts generating profit.

It’s the Survival Floor, Not a Profitability Target

Many restaurant owners confuse the break-even point with a business goal. It’s not. It’s your survival floor. If you invoice below it for weeks, you’re digging a hole that even the best plate costing won’t fill. If you invoice right on the line, you’re living to pay bills. Real profit appears once you exceed it: because from every euro you sell beyond the dead point, between 60% and 70% goes straight to margin (depending on your cost structure). That cushion is what lets you invest, distribute dividends, or simply sleep without a start.

The Question That Really Keeps You Up at Night: Your Plate Costing Checks Out, but Are You Covering Everything Else?

Knowing the cost of a dish is essential. But plate costing only tells you about raw materials, waste, and, if you do it carefully, a gross margin per dish. What it doesn’t tell you is how many plates you need to sell to pay rent, the fixed payroll, insurance, or the amortization of your stoves. That’s the sleepless question: “My food cost is healthy, why is money missing at the end of the month?” The answer always lies in the break-even threshold, which connects your kitchen to your income statement. And today you’re going to calculate it.

The Break-Even Point Formula in Two Versions

Everything boils down to one operation that, once you grasp it, you can scribble on a napkin or plug into your management software.

In Sales Euros: Fixed Costs ÷ Contribution Margin %

The most direct version is:
Break-even point (€) = Fixed costs ÷ Contribution margin %

Where Contribution margin % = 1 − (Variable costs ÷ Sales). In other words, the contribution margin is the percentage of each euro sold that remains available to cover fixed costs and, afterward, generate profit.

• If your variable costs are 35% of sales, the contribution margin is 65%.
• If your fixed costs are 24,000 € per month, your dead point is 24,000 ÷ 0.65 = 36,923.08 € in monthly revenue.

Every euro you sell above that figure will leave you 0.65 € in net contribution. Below it, you’re losing money even if the dining room is full.

In Covers and Covers per Day (the Number You Control in Each Service)

Since restaurateurs don’t invoice in abstract, we invoice tables and seats, it’s much more useful to translate the break-even threshold into covers.

• Break-even point in covers/month = Break-even point in € ÷ average ticket.
• Equivalently, if you work with the unit contribution margin:
  Break-even point in covers = Fixed costs ÷ (average ticket − variable cost per cover).

And for the day-to-day: Daily break-even point = Monthly break-even point ÷ actual days open.
Never divide by 30 or 31. If you open 26 days a month, your daily floor is the figure you need to hit each of those 26 days. Any day below it leaves a deficit that the weekend must compensate.

What the Contribution Margin Is (and Why It’s Not the Gross Margin)

Pay close attention to this nuance, because even seasoned pros stumble here. Gross margin typically refers to the difference between the selling price and the raw material cost. The contribution margin, on the other hand, subtracts all variable costs: not just food and beverage, but also POS commissions, delivery commissions, and takeaway packaging. That’s why the contribution margin is lower than the food cost, but it’s the only one that gives you a real picture of how much each dish contributes to paying your fixed structure. Working with gross margin alone is like driving while watching the speedometer and ignoring the fuel gauge.

Fixed Costs vs. Variable Costs in a Restaurant

Classifying costs correctly is the most important—and most sloppily executed—step in all the hospitality I’ve seen. If you stick a variable cost in the fixed column, your break-even point will be inflated; if you do the opposite, it’ll be false. Let’s sort it out.

Table: What Goes in Each Column (POS, Delivery, and Packaging Are Also Variable, Not Just Food Cost)

Fixed costs (exist even if no one walks in today)	Variable costs (appear only when you serve)
Rent and premises expenses	Food cost (raw materials)
Base wages + social security for the team	Beverage (beverage cost)
Insurance, licenses	POS/gateway commissions (≈1-2% of card sales)
Software, accountant, equipment depreciation	Delivery commissions (20-30% of the channel’s order)
Minimum utilities (fixed portion)	Packaging / takeaway containers

This table is gold. If you review your numbers with it in front of you, you’ll likely discover variable costs that you’d been treating as fixed—for example, Glovo or Uber Eats commissions—and by putting them where they belong, they will change your contribution margin and, with it, the entire calculation.

The Case of Labor: Fixed Base + Variable Overtime

Labor is never 100% fixed or 100% variable. The baseline team on indefinite contracts and their social security is a fixed cost: if the restaurant is closed on a Monday, those wages still run. Overtime, weekend reinforcements, or day hires for high demand are variable costs: they only appear when there’s more service. In restaurants with seasonal terraces or sharp peaks, separating these two layers keeps the break-even point from skyrocketing in the low season or artificially dropping in August.

Semi-Variable Costs (Utilities): How to Split Them

Electricity, gas, or water aren’t purely fixed or purely variable. They have a minimum fixed component (the capacity charge, maintenance) that you pay even if you don’t open, and a portion that varies with covers served. My consultant’s recommendation is to split the bill: take the lowest 20-30% of the last twelve months as fixed; assign the rest to variable, usually as an approximate percentage of sales. It’s not perfect, but it’s pragmatic and yields a much sharper break-even point than throwing the whole bill into a single bucket.

Step-by-Step Worked Example: Restaurant “Casa Mediodía”

You’ve been reading theory for a while; now let’s get our hands dirty with a real case I’ve replicated dozens of times in my audits.

Starting Data

Imagine a menu-plus-à-la-carte restaurant with these monthly figures (excluding VAT):

• Reference sales: 50,000 €/month.
• Food cost: 30% of sales → 15,000 €.
• Other variable costs (POS + packaging + delivery commissions): 5% → 2,500 €.
• Total variable costs: 35% → 17,500 €.
• Monthly fixed costs: 24,000 € (rent 4,500 + base wages incl. SS 14,000 + insurance/utilities/software/depreciation 5,500).
• Average ticket: 25 €.
• Days open per month: 26.

Step by Step to the Break-Even Point in Euros, Covers, and per Day (with Closing Check = 0 €)

Step 1: Contribution margin %
Contribution margin = 1 − (17,500 ÷ 50,000) = 0.65 → 65%.

Step 2: Break-even point in euros
24,000 ÷ 0.65 = 36,923.08 €/month.

Step 3: Break-even point in covers
36,923.08 ÷ 25 = 1,477 covers/month.
(Unit check: contribution margin per cover = 25 × 0.65 = 16.25 €; 24,000 ÷ 16.25 = 1,476.92. Identical.)

Step 4: Daily threshold
Required daily sales: 36,923.08 ÷ 26 = 1,420 €/day.
Daily covers: 1,477 ÷ 26 = 57 covers/day.

Closing check: selling exactly 36,923.08 €, variable costs are 35% → 12,923.08 €. Subtract the 24,000 € fixed and the result is 0.00 €. It balances.

Notice a key detail: “Casa Mediodía” invoices 50,000 €, well above its floor. Its real profit is 50,000 − 17,500 − 24,000 = 8,500 €/month, a 17% net margin. The break-even point isn’t a goal; it’s simply the line above which that profit starts to exist. Whatever you exceed it by is yours.

And If You Have a Menu with Many Dishes: The Weighted Average Ticket

If your menu mixes 15 € set menus with 40 € ribeyes, you can’t guess an average price by eye. You need the weighted average ticket, calculated based on each dish’s actual share of sales. A mini example: suppose you sell 100 dishes a month: 60 set menus (15 €) and 40 ribeyes (40 €). Total sales = 60×15 + 40×40 = 900 + 1,600 = 2,500 €. The weighted average ticket is 2,500 ÷ 100 = 25 €. Then, similarly, you calculate the weighted average contribution margin for each dish (price minus variable costs) and get the unit reference that feeds the formula. Without weighting, any calculation is distorted.

Break-Even Point and Food Cost: The Link Between Plate Costing and Real Profitability

Here’s the angle almost no one explains: food cost is just one piece of the puzzle. Until you plug it into the break-even equation, plate costing tells you only half the truth.

The Costly Mistake: Healthy Food Cost but Below Break-Even Point = You’re Still Losing Money

I’ve seen dozens of restaurants with perfect plate costing, 30% food cost, controlled waste… and monthly losses. “Casa Mediodía 2”—let’s call it that—invoices 21,554 €/month net, with fixed costs of 16,200 €/month, 30% food cost, and 2% other variables. Its contribution margin is 100 − (30 + 2) = 68%.
Break-even point = 16,200 ÷ 0.68 = 23,824 €/month, about 1,134 €/day (opening 21 days).
Real profit = 21,554 − (6,897 of variables + 16,200 of fixed) = −1,543 €/month. A silent hole. You can replicate this exact case with the break-even point calculator and you’ll get the same red verdict.

A key nuance that sets us apart: to close that 1,543 € hole, it’s not enough to sell 1,543 € more per month. From each new euro, only 0.68 € remain to cover fixed costs and profit. You need to sell 2,270 € more per month (1,543 ÷ 0.68), roughly 108 € extra per day. Selling “a little more” doesn’t save a business below the dead point: you have to sell quite a bit more, or lower your fixed structure. The break-even point gives you the exact measure of that effort.

Final message from this case: this restaurant’s plate costing is impeccable, its food cost is at 30%, and it still loses money. Because its fixed-cost structure is too high for its sales. Plate costing never warns you about this. The break-even point does, and a daily P&L will remind you every night.

How Much Your Break-Even Point Drops If You Fine-Tune Your Plate Costing

Now let’s take “Casa Mediodía 1” and simulate the team refining recipes, portions, and waste to lower food cost from 30% to 25%. Total variable costs go from 35% to 30%, and the contribution margin rises to 70%.
The new break-even point is 24,000 ÷ 0.70 = 34,286 €/month, versus the original 36,923 €. That’s 2,637 € less floor each month. That’s why plate costing and the dead point must always dance together: every tenth of a food cost point you shave lowers the bar you have to jump over to survive.

2026 Benchmarks: Food Cost, Prime Cost, and Net Margin by Type of Restaurant

Macro numbers don’t replace your own calculation, but they help you place yourself. These indicative ranges, based on my recent audit experience, let you compare whether your structure is in normal or risk territory.

Type of restaurant	Food cost %	Prime cost % (food + labor)	Typical net margin
Fine dining	28-32%	55-65%	3-5%
Casual dining / set menu	30-35%	58-65%	4-6%
Fast casual	25-30%	50-60%	6-10%
Café / brunch	28-35%	55-65%	5-8%
Artisan pizzeria	22-28%	50-58%	8-12%
Cocktail bar	18-24%	45-55%	8-12%

Golden rule: A prime cost (sum of food cost and labor cost) sustainably above 60‑65% of sales is the danger zone. The net margin of an average restaurant in Spain rarely exceeds 8%, and most hover in a modest 3‑6%. That’s why the break-even point is scrutinized so closely: any sales deviation can eat, in weeks, what it took months to earn.

How Often to Recalculate the Break-Even Point (and How to Stop Doing It Manually)

Your restaurant’s numbers change faster than you think. You raise the average ticket by three euros, renew your fish supplier, sign a wage increase, switch your payment gateway… each of those moves alters your dead point. My consultant’s recommendation: recalculate at least with every menu change, every rent or wage hike, and in any case, once a quarter. For seasonal businesses, before the high season starts and after it ends.

From the Static Monthly Number to Daily Control: Am I Ahead or Behind My Break-Even Point Today?

The break-even point explained in a spreadsheet is a static monthly snapshot. But a restaurant’s profitability is at stake every day, in every service. The real mental leap is connecting the monthly figure to a daily P&L that tells you, when you close the till, whether you covered your floor today or whether you have to row harder tomorrow to compensate. Without that daily control, the dead point is an academic number that you consult late, poorly, and never. With it, you know before the week is out whether your business is ahead or behind. And in hospitality, that’s worth a fortune.

The 6 Most Common Mistakes When Calculating the Break-Even Point

1. Confusing gross margin with contribution margin. If you only subtract food cost and forget delivery commissions, POS, or packaging, you’ll inflate the margin and get an artificially low dead point.
2. Not separating the fixed and variable parts of labor. If you dump all payroll into fixed, your break-even threshold skyrockets in slow months and you don’t see the real relief that variable contracts bring.
3. Dividing the monthly break-even point by 30 days. An absurdly widespread mistake. Your daily floor is calculated with real opening days; otherwise, each shift looks easier than it actually is.
4. Calculating it with VAT included. All components—sales, costs—must be net of VAT, like in accounting. If you include 10% or 21%, you completely distort the result.
5. Forgetting semi-variable utility costs. Dumping the whole electricity bill into fixed is a classic error that artificially bloats fixed costs.
6. Omitting delivery and packaging costs as variables. Today, with 20‑40% of sales through delivery channels, that oversight can skew your dead point by thousands of euros a month.

Calculate Your Break-Even Point Now (and Stop Looking at Your Business with One Eye Shut)

I’ve spent my entire career convinced that a restaurant’s numbers should be within reach of any owner, not just those with a controller. That’s why at Miselup we’ve joined three legs that change management: recipe costing tells you how much each dish costs you; the break-even point tells you how much you need to sell to avoid losing money; and the daily P&L tells you, every night, whether today you were ahead or behind your floor. No smoke. With your business’s data flowing in automatically.

You can use the free break-even point calculator to reproduce all the examples in this article with your own numbers, or you can start free and finally see your dead point updated daily. If you want to dive deeper into plate costing, before jumping into the numbers you have a complete guide on how to cost a dish step by step and another must-read: theoretical vs actual food cost. And once you’re clear on your recipe costs, the recipe costing tool directly links to the selling price and margin calculation. All connected, as it should be.

(Obviously, if you want to scale your control, you can check out the Miselup plans, but the important thing is that you start measuring, whether on a spreadsheet or with software.)

Frequently Asked Questions

How is a restaurant’s break-even point calculated?

Divide the sum of all monthly fixed costs by the contribution margin percentage. The contribution margin is calculated as 1 minus the ratio of total variable costs to sales. The exact formula is: Break-even point (€) = Fixed costs ÷ (1 − (Variable costs ÷ Sales)). The result is the VAT-exclusive revenue you need to invoice each month to break even.

How many covers per day do I need to avoid losing money?

It depends on your average ticket, your fixed costs, and your contribution margin per cover. First find your break-even point in euros, divide it by the average ticket, and then by the actual number of days you open in a month. Never divide by 30. If you need 1,420 € per day and your average ticket is 25 €, you need 57 covers daily.

What’s the difference between fixed and variable costs in a restaurant?

Fixed costs exist even if you don’t open the door (rent, base wages, insurance, depreciation). Variable costs appear only when you serve (food cost, POS or delivery commissions, packaging). To calculate the break-even point correctly, you must separate them precisely, including digital commissions as variable.

Is food cost a fixed or variable cost, and how does it enter the formula?

It’s variable, and one of the most important. It enters the formula as part of total variable costs. Together with other variables (delivery, packaging, POS), it determines the contribution margin. A lower food cost increases that margin and directly reduces the break-even point.

How much do I need to invoice per month to avoid losing money?

The exact figure comes from your own calculation. As a reference, a restaurant with 24,000 € in fixed costs and a 65% contribution margin must invoice 36,923 € per month. If your structure is different, each percentage point of margin changes the number.

How often should I recalculate the break-even point?

At least quarterly, and mandatory after any significant change: new average ticket, rent increase, change of suppliers, wage adjustment, or adding delivery channels. In high and low seasons, recalculate before the season starts.

How can I lower my restaurant’s break-even point?

There are three levers: reduce fixed costs (renegotiate rent, adjust baseline staff), increase the contribution margin (lower food cost or waste, renegotiate delivery commissions), and raise the average ticket without blowing up variable cost. The quickest is usually fine-tuning plate costing and portions, because every food cost point saved reduces the necessary revenue floor.

What’s the difference between gross margin and contribution margin?

Gross margin usually means the difference between selling price and raw material cost. Contribution margin subtracts all variable costs: food cost, beverages, POS commissions, packaging. For the break-even point, always use contribution margin; using gross margin gives a deceptively optimistic calculation.

How do I calculate the break-even point if I have a menu with many differently priced dishes?

Don’t use a single dish’s price. Calculate your weighted average ticket based on each dish’s actual share of sales. Then obtain the weighted average contribution margin of the entire menu. With those two figures, apply the same formula as with a single ticket. The result will reflect your true sales mix.
