Restaurant owners should focus on a handful of metrics that actually drive decisions. Tracking everything is overwhelming. Tracking the right things tells you where you’re making money and where you’re bleeding it.

Prime cost is the most important number. It’s food cost plus labor cost, expressed as a percentage of sales. For most restaurants, prime cost should land between 55% and 65%. Above that range, you’re leaving little room for rent, utilities, and actual profit. If your prime cost is 70%, you’re probably losing money even on busy nights.

Food cost percentage tells you how much you spend on ingredients relative to what you sell. Calculate it by dividing cost of goods sold by food sales. Most restaurants target 28% to 35% depending on the concept. A pizza shop might hit 25%. A steakhouse might run 38%. What matters is knowing your number and watching for changes. If food cost jumps 3 points in a month, something happened with portion sizes, waste, theft, or supplier prices.

Labor cost percentage works the same way but for staffing. Divide total labor costs including wages, payroll taxes, and benefits by total sales. Full-service restaurants typically run 30% to 35%. Quick service might hit 25% to 30%. This metric tells you whether you’re overstaffed on slow nights or running too lean during rushes.

Break-even is the daily or weekly sales number you need to cover all your costs. Knowing your break-even lets you make real-time decisions. If Tuesday’s break-even is $2,400 and you’re at $1,800 by dinner, you know you need a strong service or you’re losing money that day. Phoenix area bookkeeping services that understand restaurants can help you calculate this number and set up reporting that shows where you stand each week.

Cash flow matters more than profit in restaurants. You can show a profit on paper and still run out of cash because of timing. Track actual cash on hand weekly. Know when rent hits, when payroll clears, when your food distributor gets paid. Most restaurant failures aren’t about bad food. They’re about running out of cash at the wrong time.

Revenue per labor hour helps you staff smarter. Divide total sales by total labor hours worked. If you’re paying for 200 labor hours and generating $4,000 in sales, you’re at $20 per labor hour. That number should stay consistent week to week. A sudden drop means you’re overstaffed or sales are falling.

Track these weekly, not monthly. Restaurants move too fast for monthly reporting to catch problems in time. By the time you see a bad month in your financials, you’ve already lost money for four weeks. Weekly tracking lets you adjust portion sizes, schedules, and purchasing before small problems become serious losses. Restaurant accounting should be set up to produce these numbers regularly, not bury them in generic categories that don’t tell you anything actionable.
