Restaurant prime cost

Last updated: October 21, 2026 · By the Varastiq team

Key takeaway: Prime cost = food COGS + beverage COGS + total labor (wages, payroll taxes, benefits). Divide it by total sales for prime cost %. It's the largest group of costs you can change week to week. The National Restaurant Association reported a median prime cost of 65% of sales for limited-service restaurants in 2024. Track yours weekly, by component, so you know whether food or labor moved.

What is prime cost?

Prime cost groups the two cost lines operators manage every shift: what you spend on what you sell (food and beverage COGS) and what you spend on the people who make and serve it (labor). Rent, utilities, marketing and the rest sit outside it, and they're mostly fixed in the short run. That makes prime cost the number where weekly decisions show up.

What is the prime cost formula?

COGS         = Food COGS + Beverage COGS
             (each = Beginning inventory + Purchases − Ending inventory)
Labor        = Wages and salaries + Employer payroll taxes + Benefits
Prime cost   = COGS + Labor
Prime cost % = Prime cost ÷ Total net sales × 100

What counts as labor? All front- and back-of-house wages and salaries, including managers, plus the employer share of payroll taxes and employer-paid benefits such as health insurance and staff meals. Leaving out taxes and benefits understates prime cost, sometimes by several points.

How do you calculate prime cost, step by step?

1. Choose a period. A week is best for control. Use the same days for every input.
2. Calculate food and beverage COGS with the same method as food cost: beginning + purchases − ending. See how to calculate food cost percentage.
3. Total labor for the period from payroll: wages, salaries, employer taxes, benefits. For salaried staff, use the weekly share.
4. Add COGS and labor. That's prime cost in dollars.
5. Divide by total net sales and multiply by 100.
6. Keep the components. Food %, beverage % and labor % tell you what moved.

What does a worked example look like?

A full-service restaurant, one week:

One point of prime cost at this volume is $420 a week, or $21,840 a year. If the owner targets 62%, this week ran $1,560 over.

Illustrative example, not customer data.

What is a good prime cost percentage?

Here's what published data supports, and what it doesn't:

You can't add the two full-service medians (36.5% + 32.0%) to get a full-service prime cost median. The median of a sum isn't the sum of the medians, and the food figure excludes alcohol. We haven't found a published full-service prime cost median to cite. Some industry guides quote 60–65% as a planning rule of thumb. At least one of them (Bzz, accessed October 20, 2026) notes that it's a rule of thumb, not survey data.

The NRA also reported median pre-tax income of 2.8% of sales for full-service and 4.0% for limited-service restaurants in 2024. With margins that thin, a couple of points of prime cost can be the difference between profit and loss.

The practical target is the prime cost that leaves room for your occupancy and other operating costs and still leaves a profit. A restaurant with low rent can carry a higher prime cost than one in an expensive location.

Why manage food and labor together?

Because they trade off, and managing one alone can hurt the other:

• Buying pre-cut produce raises food cost and cuts prep hours.
• Adding a prep cook raises labor and may cut waste and over-portioning.
• Simplifying the menu can lower both, with fewer SKUs to waste and fewer stations to staff.
• Cutting a closing shift lowers labor, but if it means skipped breakdown and spoiled product, food cost rises.

Prime cost shows the net effect of each decision.

How do you lower prime cost?

Food and beverage side

1. Find and fix variance first. It's money lost without any benefit to guests. See theoretical vs actual food cost.
2. Re-cost plates at current invoice prices and re-price where margin slipped. See the menu pricing calculator.
3. Order to par so you don't buy what's already on the shelf.
4. Use yield tests on high-cost proteins. See the yield calculator.

Labor side

1. Schedule to forecast sales by daypart, not by habit.
2. Watch overtime weekly, not at payroll close.
3. Cross-train so you can run leaner on slow shifts.
4. Cut task time. A count that takes half the morning is labor too.

How often should you calculate prime cost?

Weekly. Monthly prime cost arrives after the schedule, the orders and the menu prices that caused it are already in the past. A weekly number lets you change next week's schedule and orders.

How does Varastiq calculate prime cost?

Varastiq builds prime cost from data you already produce. COGS comes from counts in the Stiq app and captured invoices. Sales come from Toast (read-only) or a supported item-level sales report. Labor costs come from Toast time entries, a supported wages CSV or manual entry. You see food %, beverage %, labor % and prime cost by week. See prime cost in Varastiq.

Frequently asked questions

What is prime cost in a restaurant?

Prime cost is the total of food cost, beverage cost and labor cost for a period. It is usually expressed as a percentage of total sales.

How do you calculate prime cost percentage?

Add food cost of goods sold, beverage cost of goods sold and total labor cost including payroll taxes and benefits, then divide by total net sales and multiply by 100.

What is a good prime cost percentage?

The National Restaurant Association reported a 65% median prime cost for limited-service restaurants in 2024. Some guides quote 60 to 65% as a rule of thumb. The right target depends on your occupancy costs and profit goal.

Does prime cost include salaried managers?

Yes. Prime cost labor includes all wages and salaries, including managers, plus employer payroll taxes and benefits.

Is prime cost the same as COGS?

No. COGS covers food and beverage only. Prime cost is COGS plus labor.

Why is prime cost important?

It combines the largest costs a restaurant can change week to week, so it shows the net effect of decisions about menu, purchasing and scheduling.

How often should I calculate prime cost?

Weekly. That gives you time to adjust schedules and orders before the month closes.
