The 4 Calculators
Start with what you need most. The food cost, labor cost, and prime cost triangle is the highest-leverage set for any restaurant operator, plus ingredient-level recipe costing.
Your ideal food cost target vs your actual food cost, by menu item and by week. The National Restaurant Association targets 28 to 35 percent. Know where you stand.
Ingredient-by-ingredient plate cost, yield-adjusted. Shows exact food cost percent per item and what price gets you to your target margin. Recipe engineering made visible.
Total labor as a percent of revenue, by shift and by week. Covers hourly wages, employer FICA, and overtime burden. NRA target: 30 to 35 percent. US BLS foodservice wage data sourced.
Food cost plus labor cost as one number. Industry benchmark: prime cost under 60 percent of revenue is healthy. Above 65 percent is a warning. See where your operation sits.
Restaurant and commercial kitchen calculators. Food cost, labor cost, prime cost, and recipe costing. The numbers every operator has to get right, figured out in plain English. No signup. No lead forms. No fluff.
Most restaurants do not fail because the food is bad. They fail because the owner did not know their food cost percentage, their labor cost percentage, or their prime cost until the bank account told them. These four numbers run together, and if you are not tracking all four, you are flying without instruments.
This primer covers what each number means, where the industry benchmarks come from, and how equipment decisions feed into the whole picture. Every FigureNerd calculator here is built from these fundamentals, with primary sources cited so you can check the math yourself.
Food cost percentage is the cost of ingredients sold divided by the revenue from those sales. A restaurant that spends $3.50 in food to produce a plate that sells for $12 has a food cost of 29.2 percent.

These are targets, not guarantees. A restaurant at 38 percent food cost is not automatically in trouble if its labor cost is 24 percent and its fixed costs are lean. That is why food cost alone is a lagging indicator. The number you actually manage is prime cost.
Labor cost percentage is total labor expense divided by total revenue. Total labor includes wages, employer-side payroll taxes (FICA is 7.65 percent of wages on the employer), and any benefits. It does not include the owner's draw unless the owner is also on payroll.
The US Bureau of Labor Statistics pegs median hourly wages for food preparation and serving workers at $14.22 nationally as of the most recent release, with significant variation by state. Minimum wage floors in California, New York, and Washington push the effective floor well above federal minimum. Restaurant operators in those states routinely see total labor cost reach 40 to 45 percent before any management adjustment.

Labor Cost Benchmarks
Labor is the most controllable cost on a week-to-week basis, which is also why it is the most abused. Cutting hours to hit a labor number without adjusting the schedule to match real covers is the fastest path to poor service, poor reviews, and slower future cover counts.
Prime cost is food cost plus labor cost. It is the most predictive single metric of restaurant viability because it captures the two largest variable expenses together. A restaurant that manages prime cost manages its survival.
Industry standard: prime cost below 60 percent of revenue is the target for a viable independent restaurant. Between 60 and 65 percent, you are thin. Above 65 percent, fixed costs (rent, utilities, insurance, debt service) will grind you down unless your volume is exceptional.
Example: a restaurant doing $80,000 per month in revenue with $25,600 in food cost (32 percent) and $26,400 in labor (33 percent) has a prime cost of $52,000, or 65 percent. That owner is one slow month away from a cash problem and needs to understand that before the month arrives, not after.
Break-even analysis answers the question the prime cost number cannot: given your fixed costs and your prime cost percentage, how many covers at what average ticket do you need to open the doors and not lose money?
Fixed costs for a restaurant typically include base rent, triple-net charges, general liability insurance, equipment loan payments, and management salaries. For an independent operator, $15,000 to $35,000 per month in fixed costs is common depending on market and concept size.
If your contribution margin (what is left after food and labor per dollar of revenue) is 35 cents, and your fixed costs are $20,000 per month, you need $57,143 in monthly revenue to break even. At a $22 average ticket, that is 2,598 covers. At five days per week, that is 130 covers per day. That is a number you can put on a schedule.
Commercial equipment choices, from dishwashers to refrigeration, show up in your numbers indirectly. Reliable, correctly sized equipment protects product and cuts waste; equipment that runs poorly or fails does the opposite. A walk-in that cannot hold temperature during peak days spoils product and drives food cost up. If equipment reliability is behind a rising food cost number, start with the food cost percentage calculator above to see how much it is actually costing you.
Hadassah Enterprises Inc is a management and advisory company operating across multiple service verticals. Among our active clients, we work extensively in HVAC, refrigeration, mechanical systems, and commercial food equipment, supporting equipment-purchase decisions, vendor selection, and operational efficiency for restaurant operators, building owners, and small business clients. That operational depth is why the math here is built the way it is: not as a generic percentage calculator with a number and a wave, but as a tool that shows the underlying load calculation, the benchmark it is checked against, and the source it came from. If the math does not hold up to scrutiny, it should not be in the calculator.
