Most restaurant owners know their sales number. Some know their food cost. Very few know all twelve of the numbers that actually determine whether their restaurant is healthy or quietly failing. This is the list.
These twelve metrics come from the performance analysis framework Rod Downey built at Metromedia Restaurant Group in the late 1990s, when the group was operating more than 700 company-owned restaurants across Bennigan's, Steak and Ale, Ponderosa, and Bonanza. At that scale, you cannot manage what you cannot measure. The framework was built to identify which units were genuinely healthy, which ones had fixable problems, and which ones had structural issues that no amount of effort would solve.
The same logic applies to a single-unit independent. The numbers do not lie, and most owners do not know them well enough to hear what the numbers are saying.
1. Prime Cost Percentage
Prime cost is food cost plus labor cost, expressed as a percentage of total sales. This is the single most important number in your business. For a full-service restaurant, prime cost should be at or below 65 percent of sales. For a quick-service concept, closer to 60 percent. If your prime cost is above 70 percent, the rest of your P&L is almost certainly underwater.
Most owners track food cost and labor cost separately. That is useful, but it misses the relationship between them. A restaurant with 28 percent food cost and 40 percent labor cost has the same prime cost problem as one with 38 percent food cost and 30 percent labor cost. The total is what matters.
2. Food Cost Percentage
Food cost should run between 28 and 34 percent of food sales for most full-service concepts. Fast casual runs tighter, around 25 to 30 percent. If you are above 35 percent consistently, you have a problem that is either in purchasing, portioning, waste, or theft. Usually a combination.
The number to watch is not just the overall food cost but the variance between theoretical food cost (what it should be based on your recipes and menu prices) and actual food cost (what you are actually spending). A gap of more than 2 points between theoretical and actual is a red flag that something is leaking.
3. Labor Cost Percentage
Labor cost, including management, hourly staff, and payroll taxes, should run between 28 and 35 percent of sales for most full-service restaurants. The right number depends on your concept, your service model, and your local labor market. What matters is whether it is trending in the right direction and whether it is in line with your sales volume.
Labor is the most controllable cost in a restaurant, and it is also the one most owners manage the worst. The U.S. Bureau of Labor Statistics tracks average labor costs for the food service industry, which provides useful context for benchmarking your own numbers.
4. Rent as a Percentage of Sales
Rent, including base rent, CAM charges, and any percentage rent clauses, should be at or below 10 percent of total sales. At 10 to 12 percent, you are in a yellow zone. Above 12 percent, you are in serious trouble, and above 15 percent, the math almost never works regardless of what else you do.
This is the number that kills more restaurants than any other, because it is the one you cannot control once you sign the lease. If your rent is too high relative to your sales, the only paths forward are to grow sales substantially, negotiate a rent reduction, or exit.
5. Controllable Profit Margin
Controllable profit is what is left after food cost, labor cost, and direct operating expenses (paper goods, cleaning supplies, small equipment, utilities) but before rent, depreciation, and debt service. This is the number that tells you whether the restaurant itself is operationally viable, separate from the real estate question.
A healthy full-service restaurant should generate 20 to 25 percent controllable profit. If you are below 15 percent, the operation is struggling. If you are below 10 percent, you are almost certainly losing money after rent.
6. Sales Per Square Foot
Sales per square foot measures how efficiently you are using your space. For a full-service restaurant, a healthy range is $250 to $400 per square foot annually. Below $200 per square foot, you are likely underperforming for your rent. Above $500, you may be capacity-constrained.
This number matters most when evaluating whether your sales volume is realistic for your location and footprint. A 4,000-square-foot restaurant doing $600,000 in annual sales is generating $150 per square foot. That is a problem regardless of what the food tastes like.
7. Table Turn Rate
Table turn rate is the number of times each table is occupied during a service period. For a full-service lunch, a healthy turn rate is 1.5 to 2.0. For dinner, 1.0 to 1.5. If you are consistently below 1.0 at dinner, you have a traffic problem, a pacing problem, or both.
Turn rate connects directly to sales per square foot. You cannot fix a sales problem by hoping for more customers if your tables are sitting empty between turns.
8. Check Average
Check average is total food and beverage sales divided by the number of covers served. This number tells you whether your menu is priced correctly for your concept and whether your staff is selling effectively.
A declining check average is often the first sign of a concept that is losing its positioning. Guests are ordering less, trading down, or skipping add-ons. It can also signal that your pricing has not kept up with your costs.
9. Daypart Mix
Daypart mix is the percentage of your total sales that comes from each meal period: breakfast, lunch, dinner, and late night. A restaurant that does 80 percent of its sales at dinner is far more vulnerable than one that is balanced across two or three dayparts. One bad dinner week can be catastrophic. One bad lunch week barely moves the needle.
This is one of the most underanalyzed numbers in independent restaurants. See the separate article on daypart mix for a deeper look at why this matters and what to do about it.
10. Employee Turnover Rate
Employee turnover in restaurants is notoriously high. The National Restaurant Association consistently reports industry-wide annual turnover rates above 70 percent. But there is a significant difference between industry-average turnover and the turnover rate at a well-run restaurant versus a struggling one.
If you are replacing more than half your hourly staff every six months, you have a management problem, a culture problem, or both. High turnover drives up training costs, drives down service quality, and signals to your remaining staff that something is wrong.
11. Average Weekly Sales Trend
This is not a single number but a direction. Is your average weekly sales number going up, flat, or down over the trailing 12 weeks? Over the trailing 26 weeks? The trend matters more than any single week.
A restaurant with flat sales is not in crisis, but it is not growing either. A restaurant with declining sales over two consecutive quarters has a structural problem that is not going to fix itself. The trend line is the most honest read of where the business is heading.
12. Cash Position and Runway
How many weeks can you operate at current burn rate without additional capital? This is the number that determines whether you have time to fix things or whether the clock has already run out.
Most owners do not calculate this number explicitly. They have a sense of whether the bank account is comfortable or tight, but they have not done the math on how many weeks of runway they actually have. If you do not know this number, calculate it today. It is the most important context for every other decision you are making.
What to do with these numbers
The point of tracking these twelve metrics is not to generate a report. It is to know, at any given moment, which of your numbers are healthy, which are in the yellow zone, and which are in the red. A restaurant with two or three numbers in the red has fixable problems. A restaurant with six or seven numbers in the red has a structural situation that is unlikely to improve without significant intervention.
If you do not have clean data on most of these numbers, that is itself a diagnostic. The restaurants that fail are almost always the ones where the owner stopped looking at the numbers because the numbers were uncomfortable to look at.
