Break Even Analysis for Restaurants: How to Calculate B.E.P

A break-even analysis can help you determine fixed and variable costs, set prices and plan for your business's financial future. Read on to learn more about finding the break-even point for your restaurant.

Break even point

Seventy-eight percent of restaurateurs check their financial metrics every day, according to Toast data. Even so, many owners and operators say they aren’t always clear on how to interpret the data, and how to use it to help optimize their businesses.

Analyzing your costs and manipulating financial formulas and calculations can be intimidating. But it doesn’t have to be, because once you understand how to interpret your data, you’ll be able to more proactively manage your restaurant’s financial health and day-to-day operations.

Every aspect of restaurant operations is affected by data and analytics. Knowing what to look for and how to read and calculate your numbers is essential for managing your money, keeping revenue up, and ensuring costs stay down. Learning how to determine a break-even point helps bring the overall health of your restaurant into perspective.

What is break-even point?

One of the key figures to watch is your restaurant’s break-even point. The break-even point refers to the amount of revenue necessary to cover the total fixed and variable expenses incurred within a specified time period of operating your restaurant.

Read on to understand how to calculate break-even point and how to keep an eye on this important metric. 

How to Calculate the Break-Even Point for Your Restaurant

Break-even analysis can be challenging for restaurants: You’re measuring today’s business performance with tools and information based on historical accounting data from the past — but it’s critical. 

A restaurant break-even point analysis helps you understand how many people your restaurant needs to serve for the business to make money, based on a determined average price point per guest. To do this, it’s important to conduct accurate cost accounting; it’s also important for your restaurant POS system's sales reporting to deliver accurate data on guest averages.

Break-even analysis also focuses on making sense of your fixed and variable costs. Here’s a breakdown of the two, as well as mixed costs.

How to Balance a Restaurant Budget

After you set your restaurant budget, balancing month-to-month cash flow can be complex. We spoke with restaurateurs about how they keep their costs in check.

Restaurant Fixed Costs

Your fixed costs include expenses that must be paid regardless of production or sales volume. A great way to distinguish between fixed and variable costs is to ask yourself, “What expenses do I still have to pay even if I don't get a single customer?”

A few common fixed costs include:

Restaurant Variable Costs

Variable costs vary in proportion to production. Your variable costs also take into consideration anything that gets more expensive as a result of more business. Variable costs may include:

  • Food and drink costs

  • Cleaning supplies

  • Disposables and garbage bags

  • Credit card processing fees

  • Labor costs

Restaurant Mixed Costs

It’s worth mentioning mixed costs, which are costs that waver between being fixed and being influenced to a degree by factors like sales volume.

Break-even calculation requires grouping mixed costs with fixed costs. Two examples of mixed costs are power and water, which may vary month-to-month but typically don’t drift too far from the norm.

What is the Break-Even Point Formula?

Here is how to calculate the break-even point in units of the number of guests for a given period of time:

Break-Even Point = Total Fixed Costs ÷ (Average Revenue Per Guest - Variable Cost Per Guest)

In the restaurant industry, the units are the guest counts (or the number of “covers”) themselves. Our unit price is essentially the dollar amount of our “guest average.” This isn’t always the easiest way to look at things, and that’s mostly because of the difficulty in obtaining the “variable cost per guest” component. 

Some restaurants will have worked out their estimated margins on food and drinks based on an expanded analysis of recipes and cost of ingredients. But most restaurants don’t have an entire chart of accounts neatly categorized into fixed and variable costs to accurately conduct a complete break-even analysis.

As an alternative, this variation of the formula works well. You only need three values: total sales, total fixed costs, and total variable costs:

Break-Even Point = Total Fixed Costs ÷ (Total Sales - Total Variable Costs ÷ Total Sales)

Once you’ve categorized your fixed and variable costs for a given period, this formula allows you to quickly calculate your restaurant’s break-even point in sales dollars. All you have to do is gather basic accounting reports, without yet factoring in guest counts or the dollar averages per guest.

Let's break this down a bit to see how we got to this.

You can think of a break-even point in dollar amounts like this: For a given period, at what sales volume did my total contribution margin break-even my bottom line, offsetting my total fixed costs, after which point each additional dollar earned went straight to contributing to my net income?

Let’s see how you calculate the percentage of each sales dollar that is available to cover your fixed costs and profits using this formula: Break-Even Point = Total Fixed Costs ÷ Contribution Margin Ratio. We can get to this using a series of calculations:

  • Contribution Margin = Total Sales - Total Variable Costs

  • Contribution Margin Ratio = Contribution Margin ÷ Total Sales

  • Contribution Margin Ratio = (Total Sales - Total Variable Costs ÷  Total Sales)

  • Break-Even Point = Total Fixed Costs ÷ (Total Sales - Total Variable Costs ÷  Total Sales)

With this formula, we simply remove the guest count component to answer the question, “At what point did I break even and start adding profit to my bottom line?”

Let's look at an example. Last quarter, let's say you…

  • Introduced a new menu and slightly raised prices

  • Printed new menus, which only happens a few times a year

  • Started using new vendors that you negotiated into contract pricing

  • Brought on a new restaurant management team

  • Invested in a new kiosk system, costing you a fixed monthly amount but saving you money on labor

Knowing this information, we should use the last three months of accounting data to reset our way of finding the break-even point. It’s a good idea to use a moving average of these expenses and sales figures. Using moving averages allows you to account for the quirks of all the miscellaneous expenses that still impact your bottom line, while still updating your historical numbers with the most recent month's closing figures.

Let’s look at these example statistics from a restaurant’s last quarter:

  • The restaurant had $450,000 in sales.

  • Their total variable costs amounted to $180,000.

  • Their total fixed costs amounted to $200,000.

Now, let’s turn these costs into one-month averages:

  • On average, the restaurant had $150,000 in sales per month.

  • On average, the restaurant had $60,000 in variable costs per month.

  • On average, the restaurant had $66,666 in fixed costs per month.

With these numbers, we’ll first subtract the number of total variable costs ($60,000) from total sales ($150,000). Next, we divide that difference ($90,000) by the total sales number ($150,000). Then, we take one minus that quotient (0.4), which equals 0.6. Finally, we divide the total fixed costs ($66,666) by 0.6.

Ready to see it all made clear? Using this example, let’s crunch some numbers to see how to calculate break-even point in dollars:

  • Break-Even Point = Total Fixed Costs ÷ (Total Sales - Total Variable Costs ÷ Total Sales)

  • Break-Even Point = $66,666 ÷ ($150,000 - $60,000 ÷ $150,000)

  • Break-Even Point = $66,666 ÷ ($90,000 ÷ $150,000)

  • Break-Even Point = $66,666 ÷ 0.6

  • Break-Even Point (in Dollars) = $111,110

In this example, we calculated that the restaurant’s break-even point was when it reached an average of $111,110 in sales per month.

Let’s say you discovered from your sales records that the average dollar amount per guest for the same previous three months is $45. You can use that number to determine your break-even amount when it comes to the number of guests you need per month. All you need to do is divide your monthly break-even amount by the average amount spent per guest.

  • Break-even point (in guests) = $111,111 ÷ $45

  • Break-even point = 2,469 guests

  • Comes out to an average of 83 guests per day

There you have it. We hope these formulas and breakdowns help you better understand how to calculate break-even point for your restaurant.
