What's a Good Prime Cost for a Bar vs a Restaurant?

“Prime cost should be 60%.” I have heard that a hundred times. It is a fine starting point and a bad target, because 60% means something completely different for a cocktail bar than it does for a full-service steakhouse. The right number tracks your concept. Treat one figure as the goal across every kind of operation and you get good bars that think they are failing and struggling kitchens that think they are fine.

Here is what a healthy prime cost actually looks like by concept, and why the number moves.

The short answer #

Prime cost is food and beverage cost plus fully loaded labor, divided by sales. A healthy number depends on the concept: bars 50 to 55%, quick service and fast casual 55 to 60%, sit-down restaurants 60 to 65%, fine dining up to 70%. Run it weekly, not monthly, and when it’s high, check which half is heavy (food or labor) before you fix anything.

How to calculate it #

Prime cost % = (food and beverage cost + total labor) ÷ total sales × 100

The math is easy. What goes into each bucket is where people get it wrong.

Cost of goods means food and beverage. A kitchen running a great 28% food cost next to a 28% pour cost on beer still runs hot on prime cost, because the bar side is leaking and nobody’s looking at it.

Total labor means fully loaded, not the gross wages on the payroll report. Add employer FICA (7.65%), federal and state unemployment, workers comp (3 to 7% of payroll in restaurants), health insurance if you offer it, paid time off, and manager salaries for the week. All of that runs 25 to 35% on top of gross wages (Restaurant365, Toast). Run prime cost on gross wages alone and you understate it by 4 to 6 points.

A worked week. A casual full-service spot does $82,000 in sales:

• Food: $14,200 beginning inventory + $22,800 purchases − $13,400 ending = $23,600
• Beverage: $8,400 + $5,200 − $7,800 = $5,800
• Labor: $9,800 hourly + $1,750 manager + $3,234 payroll burden (about 28%) + $620 health insurance = $15,404
• Prime cost: ($23,600 + $5,800 + $15,404) ÷ $82,000 = 54.6%

That’s under the 60 to 65% band for a sit-down restaurant, which means room to buy better ingredients, hold prices for a season, or pay people more without risking the model.

Why weekly. A monthly prime cost is a postmortem: by the time it lands, the week that broke it is four weeks gone. A 65% week on a 60% target costs you about 1% of that week’s sales. Catch it in week one and you eat 1%. Wait for the month to close and you eat 4% for the same mistake. All you need is a Sunday night count of your top items, sales from the POS, and labor from the time clock with a 28% burden applied. Call it forty minutes on a Monday morning.

This post is mostly about what the number should be. Here’s the benchmark.

Benchmark by concept #

Concept	Healthy prime cost	Why
Bar / cocktail-led	50 to 55%	High beverage margin pulls COGS down
Quick service / fast casual	55 to 60%	Lower labor, moderate food cost
Full-service restaurant	60 to 65%	Balanced food and labor load
Fine dining	60 to 70%	Labor-heavy service drives it up
Pizza / high-margin niche	55 to 60%	Cheap food cost offsets labor

These are healthy ranges, not red lines. A full-service restaurant at 66% is not on fire. But it has no cushion, and at full-service margins there is not much room below the prime-cost line for rent, utilities, and profit.

Why bars run lower #

Beverage margin. That is the whole reason, start to finish. Spirits poured straight run a 14 to 18% pour cost, which is far better than the 28 to 35% food cost a kitchen lives with. A bar-led concept is selling a bigger share of its revenue as high-margin liquor, so its combined COGS sits lower, and that drags the whole prime cost down with it. A bar at 52% prime cost is not doing anything magical. It is selling a product that costs less to make. Same reason a restaurant that adds a strong bar program can pull its overall prime cost down a few points without touching the kitchen.

Why fine dining runs higher #

Labor. Fine dining is service-heavy: more bodies per cover, skilled kitchen labor, longer prep. The food cost might actually be reasonable, but the labor load pushes prime cost up toward the high end of healthy.

And that is fine. A fine-dining room at 66% prime cost can absolutely work, because the model assumes a higher average check and a different cost structure below the line. Hold it to a 55 to 60% target meant for fast casual and you would gut the exact service the concept is selling. The number is not the enemy. Comparing it to the wrong concept is.

If you are over your range #

Here is the part I actually care about, because this is where most operators get it wrong. Prime cost splits cleanly into two levers, and the split is what tells you which one to pull. Don’t stare at the total. Break it into the food-plus-beverage piece and the labor piece:

• COGS too high? The problem is purchasing, portioning, pricing, or waste. Run inventory variance and check your food cost.
• Labor too high? The problem is scheduling, overtime, or sales per labor hour. The fix is in the schedule, not the kitchen. See reduce labor cost without cutting hours.
• Bar leaking? Pour cost above 18 to 24% across the program usually traces to free pours, comps nobody approved, and heavy hands on the well. It’s the leak people miss most. See 5 ways bar pour cost leaks.

Check them in that order: food variance is the cheapest to check and the fastest to fix, then labor by daypart, then the bar.

A 64% prime cost that is 32% food and 32% labor is a completely different problem than a 64% that is 28% food and 36% labor. Same total. Different leak. And you cannot fix it until you know which half is heavy.

What this looks like in the calculator #

The prime cost calculator on this site runs food plus beverage plus labor against your sales and shows the split, so you see your prime cost and which lever is carrying the weight at the same time. Run it weekly, not monthly. By the time a monthly number reads bad, it has been bad for four weeks and you have no idea which one.

What to do today #

Pull your prime cost for last week and put it next to your concept’s range above. Inside the range? Watch the split and keep it there. Over? Break it into food and labor and look at which half is heavy, because that one decision is what sends you into the kitchen or into the schedule. The number alone is a score. The split is the instruction.
