Restaurant Prime Cost Calculator (Free) – Labor & Food Cost Profitability

Last updated: February 2026
Reviewed by restaurant operations specialists at Teamsly

Calculate your restaurant's prime cost — the combined total of food cost and labor cost as a percentage of revenue. See where your costs rank against industry benchmarks, how labor and food split, and what you can save by optimizing either one.

This restaurant prime cost calculator helps restaurant owners calculate food and labor cost percentage to measure overall profitability. For example, an $80,000/month restaurant with $24,000 in food costs and $24,000 in labor costs has a prime cost of $48,000, or 60% — right in the healthy 55–65% target range.

What is a good prime cost for a restaurant?

A healthy prime cost target is 55–65% of total revenue. Full-service restaurants typically see 60–65%, while quick-service restaurants target 55–60%. A prime cost above 65% signals that food costs, labor costs, or both are too high — and profit margins are being squeezed. Operators who track prime cost weekly catch problems before they compound.

Why Prime Cost Is the Most Important Restaurant Metric

Prime cost is the single most telling number in restaurant finance. It combines food cost and labor cost — the two largest controllable expenses — into one metric that reveals how efficiently you turn revenue into profit. According to the National Restaurant Association, food and labor together account for 55–65% of every revenue dollar in a healthy restaurant. When prime cost drifts above that range, profit margins collapse.

Unlike rent or insurance, prime cost consists of expenses you can change this week. You can adjust portion sizes, renegotiate supplier pricing, cut overtime hours, or restructure your scheduling template — and see the impact on your next P&L statement. That's why operators who track prime cost weekly outperform those who check it only at month-end. The gap between a 60% and a 66% prime cost on $80,000 in monthly revenue is $4,800/month — or $57,600 per year.

  • It predicts profitability: A restaurant with a 58% prime cost has far more room for profit, unexpected expenses, and reinvestment than one at 67%. Knowing your prime cost tells you whether your business model is sustainable.
  • It connects food purchasing to labor scheduling: A restaurant might have low food costs but sky-high labor, or vice versa. Prime cost forces you to see the whole picture. Cutting food cost by switching to cheaper ingredients means nothing if your labor cost percentage is 38%.
  • It reveals the true cost of operational problems: Employee no-shows increase labor cost through emergency overtime. Uncontrolled overtime inflates the labor half of prime cost. Food waste increases COGS. Prime cost captures all of it.
  • It creates a shared goal for your team: Kitchen managers focus on food cost; front-of-house managers focus on labor. Prime cost gives both teams a single number to rally around.
  • It's what investors and lenders evaluate first: Before looking at revenue, experienced restaurant investors check prime cost. A $2M/year restaurant with a 68% prime cost is less attractive than a $1.2M restaurant at 58%.

Prime Cost Benchmarks by Restaurant Type

  • Quick-service / fast food 55–60%
  • Fast casual 58–63%
  • Full-service casual dining 60–65%
  • Fine dining 62–68%
  • Bars & nightclubs 50–55%
  • Catering operations 55–62%

The most common mistake is looking at food cost and labor cost as separate line items. A restaurant with 28% food cost and 34% labor cost is actually worse off than one with 32% food cost and 28% labor cost — because the first has a 62% prime cost while the second has a 60% prime cost. The combined number is what matters.

Prime cost is considered more reliable than food cost or labor cost alone because it measures total operational efficiency.

How to Calculate Restaurant Prime Cost

How do you calculate prime cost for a restaurant?

Prime Cost = Total Cost of Goods Sold (food & beverage) + Total Labor Cost (wages + benefits + payroll taxes). Then divide by total revenue and multiply by 100 to get the percentage. For example, if COGS is $24,000 and labor is $24,000 on $80,000 in revenue, prime cost = $48,000 (60%).

Calculating prime cost is straightforward, but getting accurate inputs requires discipline. Here are the three formulas every restaurant operator should know.

1. Prime Cost (dollar amount):

Prime Cost = Total COGS + Total Labor Cost

2. Prime Cost Percentage:

Prime Cost % = (Total COGS + Total Labor Cost) ÷ Total Revenue × 100

3. Component Percentages:

Food Cost % = Total COGS ÷ Total Revenue × 100
Labor Cost % = Total Labor ÷ Total Revenue × 100

Example: Full-Service Restaurant Prime Cost Calculation

Monthly revenue: $80,000
Food & beverage cost (COGS): $24,000
Total labor cost: $24,000

Prime cost: $24,000 + $24,000 = $48,000
Prime cost %: $48,000 ÷ $80,000 × 100 = 60.0%

Food cost %: $24,000 ÷ $80,000 = 30.0%
Labor cost %: $24,000 ÷ $80,000 = 30.0%

Remaining revenue (for rent, utilities, profit): $80,000 − $48,000 = $32,000 (40.0%)

What's included in "Total Labor Cost"?

Total labor cost for prime cost calculations should include: hourly wages, salaried employee pay, overtime premium pay, payroll taxes (FICA, FUTA, SUTA), workers' compensation insurance, health insurance contributions, and any other employee benefits. Many operators undercount labor cost by leaving out payroll taxes and benefits — which typically add 20–30% on top of gross wages.

Accuracy matters. If you exclude payroll taxes and benefits from labor cost, you'll underestimate prime cost by 4–8 percentage points — which could be the difference between thinking you're at 58% (healthy) and actually being at 64% (needs attention). Pull numbers from your actual P&L, not estimates.

Prime Cost Benchmarks: What's Normal for Your Restaurant Type?

Not all restaurants are created equal when it comes to prime cost. A fine-dining restaurant with a highly skilled kitchen brigade and premium ingredients will naturally have a higher prime cost than a quick-service concept with lower labor needs and commodity food inputs. The key is knowing your type's target range and staying within it.

  • Quick-service / fast food (55–60%): Lower labor costs due to simplified operations, counter service, and limited prep. Food cost is moderate (28–32%) with standardized ingredients. The labor savings create room for aggressive prime cost targets.
  • Fast casual (58–63%): Slightly higher food cost (29–34%) due to fresher ingredients and made-to-order prep. Labor is still lean but requires more skilled prep cooks than QSR.
  • Full-service casual dining (60–65%): The most common restaurant type. Food cost of 28–34% and labor cost of 30–35%. Tipped servers keep front-of-house labor lower, but kitchen labor and benefits push total labor higher.
  • Fine dining (62–68%): Premium ingredients drive food cost to 32–40%. Skilled cooks, sommeliers, and higher service ratios push labor to 30–38%. High check sizes help offset the elevated prime cost. Beverage programs with strong wine margins are critical for staying in range.
  • Bars & nightclubs (50–55%): Very low food cost (if any) and moderate labor. Beverage margins of 75–85% on cocktails and 60–70% on wine keep COGS minimal. The challenge is controlling labor during slow weeknights.
  • Catering operations (55–62%): Food cost can be lower due to bulk purchasing, but labor spikes around events. Variable scheduling makes catering prime cost more volatile week-to-week.

The 65% Rule

If your prime cost exceeds 65% consistently, you're almost certainly losing money after rent, utilities, insurance, marketing, and other overhead. At 65% prime cost, you have only 35% of revenue left to cover all other expenses and generate profit. Since non-prime operating costs typically consume 25–30% of revenue, that leaves a profit margin of just 5–10% in the best case — with zero buffer for unexpected costs.

Use the calculator above to find your current prime cost percentage, then compare it to the benchmark for your restaurant type. If you're above the range, the next two sections will help you identify whether the problem is on the food side, the labor side, or both.

How Labor Cost Drives Prime Cost Higher

Of the two prime cost components, labor is the one that changes fastest — and the one most restaurant operators underestimate. Food cost adjustments (renegotiating suppliers, re-engineering menus, reducing waste) take weeks or months to implement. But labor cost can spike this week due to a single scheduling mistake, a wave of no-shows, or unplanned overtime.

The three biggest labor cost drivers that inflate prime cost:

  1. Overtime hours: Every overtime hour costs 1.5× the regular rate under FLSA rules. A cook earning $18/hour costs $27/hour in overtime. If 5 employees each work 8 overtime hours per week, that's $1,800/week in overtime premium alone — enough to push prime cost up 2–3 percentage points. Use our overtime cost calculator to quantify the impact.
  2. Employee no-shows: When an employee doesn't show up, you either run short-staffed (hurting revenue and service quality) or call someone in at overtime rates. The National Restaurant Association estimates that no-shows cost restaurants $3,600–$7,200 per year per chronic no-show employee. Multiply that across your team and it's a direct hit to prime cost.
  3. Overstaffing during slow periods: Scheduling 12 servers for a Tuesday lunch that needs 7 doesn't just waste labor dollars — it creates idle labor cost that inflates prime cost with zero revenue contribution. Demand-based scheduling closes this gap.

The Scheduling Connection

According to a National Restaurant Association workforce survey, restaurants using automated scheduling tools report 2–4% lower labor cost percentages compared to those scheduling manually. On $80,000/month revenue, a 3% improvement saves $2,400/month — $28,800/year — straight off prime cost.

The food-to-labor ratio is a useful diagnostic. In a healthy full-service restaurant, food cost and labor cost should be roughly balanced (0.8:1 to 1.2:1). If your labor cost is significantly higher than food cost, investigate overtime, overstaffing, and benefits costs. If food cost dominates, look at waste, portion sizes, and vendor pricing. The calculator above shows your exact ratio.

5 Proven Ways to Reduce Restaurant Prime Cost

Reducing prime cost doesn't mean cutting corners — it means eliminating waste, improving efficiency, and making smarter decisions about your two biggest expense categories. Here are the five most impactful strategies, ranked by speed of implementation.

  1. Track prime cost weekly, not just monthly Monthly P&L reviews catch problems too late. By the time you see a 67% prime cost on last month's statement, you've already lost the money. Weekly tracking lets you spot a rising food or labor trend in week 2 and course-correct before the month closes. Use the same inputs from this calculator each week with your actual numbers.
  2. Optimize scheduling to match demand patterns Labor is the fastest-moving lever on prime cost. Build schedules from historical sales data: more staff during peak revenue hours, fewer during slow periods. Eliminate split-shift creep and double-coverage overlaps. Every unnecessary labor hour is a direct addition to prime cost. Demand-based scheduling tools automate this.
  3. Reduce overtime hours by 25% or more Overtime is the most expensive form of labor cost. Time-and-a-half means every OT hour costs 50% more than it should. Redistribute hours across your full team, cross-train employees to cover multiple roles, and use scheduling software that flags overtime risks before they happen. Even a 25% OT reduction can cut prime cost by 1–2 percentage points. See the overtime cost calculator.
  4. Conduct weekly food cost inventories Many restaurants only do full inventory once a month. Weekly counts on your top 20 highest-cost items (proteins, seafood, produce, dairy) catch waste, theft, and over-portioning before they compound. Pair inventory counts with actual-vs-theoretical food cost analysis — the gap between what you should have used and what you actually used reveals hidden costs.
  5. Build schedules from your break-even number If your break-even revenue is $50,000/month, you know you need roughly $1,667/day. On slower days when projected revenue is $1,200, reduce scheduled labor hours proportionally. When projected revenue is $2,400, add coverage. This anchors every scheduling decision to profitability.

Notice that 3 of these 5 strategies are scheduling- and labor-related. That's not a coincidence. Food cost optimization has diminishing returns after you've dialed in portioning, purchasing, and waste controls. But labor cost can be optimized every single week through better scheduling decisions — making it the highest-leverage prime cost lever for most restaurants.

When to Recalculate Prime Cost

Prime cost isn't a one-time calculation. It should be a living metric that you recalculate on a regular cadence and after any significant operational change. Here's when to rerun the numbers:

  • Weekly: every Sunday or Monday, enter last week's actual COGS, labor cost, and revenue into this calculator. Compare to the prior week and to your target range. This is the single most impactful financial habit a restaurant operator can build.
  • After menu price changes: raising prices by 5% should reduce your prime cost percentage — if it doesn't, food cost or labor cost has risen to absorb the increase.
  • After vendor price increases: a 10% increase in protein costs can push food cost up 1–2 percentage points, directly hitting prime cost.
  • After hiring or firing: adding 3 employees increases labor cost. Eliminating overtime-heavy positions may decrease it. Recalculate to measure the real impact.
  • At the start of each season: summer and holiday peaks bring higher revenue and higher costs. Recalculate prime cost targets for each season to avoid misreading a "good" summer number that masks a creeping cost problem.
  • After changing your schedule template: if you restructured shifts, changed opening hours, or implemented demand-based scheduling, recalculate within 2–3 weeks to quantify the labor cost improvement.
  • Before major investments: if you're considering a kitchen renovation, new equipment lease, or second location, run the prime cost numbers first. Knowing your current cost efficiency tells you whether you can afford the investment.

Common Prime Cost Mistakes Restaurants Make

Even experienced operators make prime cost errors that distort their profitability picture. Avoiding these five mistakes will give you a more accurate — and more actionable — prime cost number.

1. Separating food cost and labor cost into silos

Many restaurants track food cost in one report and labor cost in another, reviewed by different managers. This misses the whole point. A kitchen that reduces food waste by $500/month but generates $800 in extra overtime to do it has actually increased prime cost by $300. Always evaluate food and labor changes together.

2. Using monthly averages instead of weekly tracking

A monthly average of 62% prime cost can hide two terrible weeks at 68% and two good weeks at 56%. Weekly tracking reveals the volatility and lets you connect spikes to specific events: a shipment of expensive produce, a catering event that required extra staff, or a week with high no-shows.

3. Excluding payroll taxes and benefits from labor cost

Some operators only count gross wages in their labor calculation, leaving out employer-paid FICA (7.65%), unemployment taxes (FUTA/SUTA), workers' comp, and health insurance. These typically add 20–30% on top of gross wages. Excluding them understates prime cost by 4–8 percentage points — turning a dangerous 66% into a deceptively comfortable 60%.

4. Not adjusting for seasonal revenue changes

Prime cost percentage changes when revenue changes — even if costs stay flat. During a slow month with $60,000 in revenue instead of $80,000, the same $48,000 in food and labor costs produces a 80% prime cost instead of 60%. Prepare for seasonal dips by building flexible schedules that reduce labor proportionally. Use the break-even calculator to find your minimum revenue floor.

5. Comparing to the wrong benchmarks

A fine-dining restaurant shouldn't measure itself against fast-casual benchmarks (and vice versa). A 63% prime cost is excellent for fine dining but concerning for a quick-service concept. Always compare your prime cost to the benchmark range for your specific restaurant type, market, and concept.

People Also Ask

What percentage should prime cost be in a restaurant?

A healthy restaurant prime cost should be 55–65% of total revenue. Quick-service restaurants should target 55–60%, full-service casual dining 60–65%, and fine dining 62–68%. If your prime cost consistently exceeds 65%, your food costs, labor costs, or both need immediate attention. A 1% improvement in prime cost on $80,000/month in revenue saves $800/month ($9,600/year).

Is prime cost the same as food and labor cost?

Yes. Prime cost is simply the sum of food & beverage cost (COGS) and total labor cost expressed as a dollar amount or percentage of revenue. The term "prime cost" groups these two categories because they are the two largest controllable expenses in a restaurant. Together they typically represent 55–65% of revenue. Tracking them as a single combined metric helps operators see the full picture of their controllable cost structure.

How does overtime affect prime cost?

Overtime directly inflates the labor component of prime cost. Under FLSA rules, overtime hours cost 1.5× the regular rate. If 5 employees each work 8 overtime hours per week at $18/hour, the overtime premium alone is $720/week or $3,120/month — enough to push prime cost up 2–4 percentage points. Reducing overtime through better scheduling is one of the fastest ways to lower prime cost. Use our overtime cost calculator to quantify the impact.

Can scheduling software reduce prime cost?

Yes. Restaurants using automated, demand-based scheduling tools consistently report 2–4% lower labor costs compared to manual scheduling. On $80,000/month in revenue, a 3% labor cost reduction saves $2,400/month — $28,800/year — directly reducing prime cost. Scheduling software achieves this by matching staffing levels to forecasted demand, preventing overtime, filling shifts more efficiently, and reducing no-show impacts through automated notifications and swap features.

Restaurant Prime Cost Calculator FAQ

Prime cost is the sum of a restaurant's two largest controllable expenses: cost of goods sold (food and beverage) and total labor cost (wages, benefits, payroll taxes, workers' comp). It's expressed as a dollar amount and as a percentage of total revenue. Prime cost typically represents 55–65% of revenue in a healthy restaurant. It's the single best indicator of operational efficiency because it captures the cost categories you can actively manage through purchasing decisions, menu engineering, and scheduling.

Add your total food and beverage cost (COGS) to your total labor cost. That sum is your prime cost in dollars. To find the percentage, divide prime cost by total revenue and multiply by 100. For example: $24,000 COGS + $24,000 labor = $48,000 prime cost. $48,000 ÷ $80,000 revenue × 100 = 60% prime cost. Make sure to include all labor-related expenses — not just gross wages. Payroll taxes, benefits, and workers' comp should all be included.

A good prime cost is 55–65% of total revenue, depending on your restaurant type. Quick-service restaurants should target 55–60%, fast casual 58–63%, full-service casual 60–65%, and fine dining 62–68%. Bars and nightclubs with high beverage margins can achieve 50–55%. If your prime cost exceeds 65%, you're likely losing money after covering rent, utilities, insurance, and other non-prime expenses.

Total labor cost should include all people-related expenses: hourly wages, salaried employee pay, overtime premium pay, employer-paid payroll taxes (Social Security, Medicare — about 7.65%), federal and state unemployment taxes (FUTA/SUTA), workers' compensation insurance, health insurance contributions, and any other employee benefits. Excluding these add-ons understates labor cost — and therefore prime cost — by 4–8 percentage points.

Prime cost includes only food/beverage cost and labor cost — the two largest controllable expenses. Total operating cost includes everything: prime cost plus rent, utilities, insurance, marketing, equipment leases, POS fees, repairs, taxes, and all other overhead. Prime cost typically represents 55–65% of revenue; total operating costs (including prime cost) consume 85–95%. The remaining 5–15% is your profit margin. Prime cost is favored as a management metric because it reflects expenses you can change quickly.

Ideally, weekly. Monthly tracking catches problems 2–4 weeks too late. Weekly tracking lets you see trends forming and course-correct quickly. Block 15 minutes every Monday to enter the previous week's COGS, labor, and revenue into this calculator. Over time, you'll build a clear picture of your prime cost trend — and catch anomalies (high overtime weeks, expensive product deliveries, no-show spikes) within days instead of discovering them on the monthly P&L.

Scheduling directly controls the labor side of prime cost. Overstaffing creates idle labor that adds cost without generating revenue. Understaffing forces overtime when the rush hits. Poor schedule distribution creates overtime liability. No-shows require last-minute coverage at premium rates. Demand-based scheduling tools solve all of these by matching staffing levels to forecasted revenue, preventing overtime, and automating shift-filling. Restaurants that switch to automated scheduling typically see a 2–4% reduction in labor cost — which translates directly into a 2–4% reduction in prime cost.
