How to Calculate Restaurant Break-Even Point (Formula + Example)
What is the break-even point for a restaurant
The break-even point is the level of sales at which your restaurant covers all its costs but makes no profit. Below that point, you lose money. Above it, you earn profit.
Most restaurant owners think about break-even in covers per day: how many customers do I need to serve each day to pay the bills? That number depends on three things: your fixed costs, your contribution margin per cover, and how many days you are open.
Knowing your break-even point lets you answer the most important question in restaurant planning: is this concept viable in this location with this menu and this rent?
The break-even formula
The basic break-even formula is:
Break-Even Sales = Fixed Costs ÷ Contribution Margin Ratio
Fixed costs are expenses that do not change with the number of covers you serve: rent, insurance, salaried management, loan payments, and utilities (mostly). Contribution margin ratio is the percentage of each sales dollar left after you pay for food, beverage, and hourly labor.
For example, if your fixed costs are 20,000 dollars per month and your contribution margin ratio is 40%, your break-even sales are 50,000 dollars per month.
Break-Even Sales = 20,000 ÷ 0.40 = 50,000
Most operators prefer to express break-even in covers per day, not dollars per month. To do that, divide monthly break-even sales by the number of days you are open, then divide by your average check.
Break-Even Covers per Day = (Break-Even Sales ÷ Days Open per Month) ÷ Average Check
Worked example: full-service restaurant
A 60-seat restaurant is open six days per week, 26 days per month. The average check is 48 dollars. Monthly fixed costs total 28,000 dollars: rent 8,000, insurance 1,200, salaried managers 12,000, utilities 2,400, loan payment 3,200, and other fixed expenses 1,200.
The restaurant's prime cost runs at 60% of sales, according to Restaurant365 (accessed 2026), which is the low end of the 60% to 65% range for full-service restaurants. That leaves a contribution margin of 40% to cover fixed costs and profit.
Break-Even Sales = 28,000 ÷ 0.40 = 70,000 per month
Break-Even Sales per Day = 70,000 ÷ 26 = 2,692 per day
Break-Even Covers per Day = 2,692 ÷ 48 = 56 covers per day
This restaurant must serve 56 covers per day, every day it is open, just to break even. If it has 60 seats and turns each seat 1.5 times per service, it can serve 90 covers per day. That gives a margin of safety of 34 covers.
Why contribution margin matters more than gross margin
Many restaurant owners confuse gross margin with contribution margin. Gross margin is sales minus cost of goods sold (food and beverage). Contribution margin is sales minus all variable costs, including hourly labor.
Hourly labor is variable: if you serve more covers, you schedule more servers and cooks. If you serve fewer covers, you cut shifts. That makes hourly labor a variable cost, not a fixed cost, and it belongs in the contribution margin calculation.
A restaurant with food and beverage cost totaling 32% and hourly labor cost of 30% has a contribution margin of only 38%, not 68%. Using gross margin instead of contribution margin will make your break-even point look lower than it really is, and that can lead to bad decisions about rent, concept, or location.
Fixed costs vs. semi-variable costs
Some costs are neither purely fixed nor purely variable. Utilities, for example, have a base charge (fixed) and a usage charge that rises with volume (variable). Credit card fees are a percentage of sales (variable). Repairs and maintenance can spike unpredictably.
For break-even analysis, treat utilities, credit card fees, and small variable operating expenses as fixed if they do not move much with covers served. The goal is a simple, conservative estimate, not accounting precision. If you want precision, add a buffer to your fixed costs or lower your assumed contribution margin by two points.
Break-even including loan payments
The formula above includes loan payments in fixed costs. That is the right approach if you want to know the sales level required to stay current on debt and avoid default.
Some lenders and textbooks calculate break-even without debt service, then add a separate debt service coverage ratio (DSCR). DSCR measures how many times your operating profit covers your loan payment. A DSCR of 1.25 means your profit is 25% higher than your payment, giving the lender a cushion.
For an operator, break-even including debt service is more useful. It answers the question: can I pay the rent, the staff, and the bank, or do I run out of cash?
How many covers do you need per day
The break-even formula gives you the minimum. The real question is: how many covers can you serve, and how many do you need to hit your profit target?
If you have 60 seats, are open for one service per day, and turn each seat 1.5 times, you can serve 90 covers per day. If your break-even is 56 covers, you have 34 covers of margin. If your break-even is 85 covers, you have only 5 covers of margin, and any slow night puts you in the red.
Seat turnover varies by concept. Full-service restaurants typically turn tables 1.5 to 2.5 times per service, according to Complete Controller (accessed 2026). Quick-service and cafes turn faster. Bars measure turnover differently, if at all, because customers stay for multiple rounds.
If your break-even in covers per day is higher than your realistic capacity, the concept does not work. You need to lower fixed costs (cheaper rent, smaller space), raise prices (higher average check), or improve contribution margin (lower prime cost).
Use break-even to test your concept before you sign a lease
The most valuable time to calculate break-even is before you commit to a location. If the rent is 12,000 dollars per month and your contribution margin is 38%, you need 31,579 dollars of sales per month just to cover rent. Add the rest of your fixed costs, and you might need 70,000 or 80,000 dollars per month in a 50-seat space. That is 2,600 to 3,000 dollars per day, six days per week.
Can you serve 55 to 65 covers per day at a 48-dollar check in that neighborhood? If the answer is no, the rent is too high, or the concept needs a higher check or faster turnover.
Break-even analysis does not guarantee success, but it prevents expensive mistakes.
Track your break-even every month
Break-even is not static. When your rent increases, your supplier raises prices, or you add a salaried manager, your break-even point moves. Operators who recalculate break-even monthly know how much room they have between current sales and the threshold, and they can act before a slow month becomes a crisis.
Break-even starts with knowing your prime cost. The free calculator below gives you your food cost, beverage cost, labor cost, and prime cost for the month, color-coded against sourced benchmarks, from seven numbers you already have in your POS. Once you know your prime cost percentage, the formula above gives you your break-even in covers per day.
