The restaurant industry has one of the highest failure rates of any business category. Industry data consistently puts it between 17% and 60% in the first year, depending on the market and methodology. But most of those failures share a common denominator: the owners never tracked the numbers that predict survival.
The good news is that there are only five financial metrics that really matter. Master these, and you'll know — weeks before it becomes a crisis — whether your restaurant is financially healthy or quietly heading toward failure.

Metric #1: Food Cost Percentage
Food cost percentage is what you spend on ingredients relative to your food revenue. It's the most-discussed metric in the restaurant industry — and the one most operators track inconsistently.
Food Cost % = Cost of Food Sold ÷ Food Revenue × 100
Target: 28–35% for most restaurant types. Fine dining: 25–30%.
If your food cost is consistently above 38%, your menu prices are too low, your portions are too large, or you have a waste/theft problem. All three are fixable — but only if you're measuring.
The operators who track this weekly (not monthly) catch drift early. A 3-point increase in food cost percentage that goes unnoticed for 30 days costs real money. Caught in week one, it's an inventory and purchasing conversation.
Metric #2: Labor Cost Percentage
Labor is typically the largest cost in any restaurant, often exceeding even food costs. It includes hourly wages, salaried management, benefits, and payroll taxes.
Labor Cost % = Total Labor Cost ÷ Total Revenue × 100
Target: 25–35%. Full-service restaurants trend higher; fast-casual lower.
The danger zone starts around 38–40%. At that level, the combined food + labor cost is leaving little room for rent, utilities, marketing, and profit. Many restaurants fail simply because they overstaffed consistently and never noticed in their monthly reports.

Metric #3: RevPASH (Revenue Per Available Seat Hour)
RevPASH is borrowed from the hotel industry (RevPAR) and adapted for restaurants. It measures how much revenue each seat generates per hour of operation — accounting for both utilization and check size.
RevPASH = Total Revenue ÷ (Available Seats × Operating Hours)
Example: $4,000 revenue ÷ (50 seats × 4 hours) = $20 RevPASH
RevPASH reveals problems that standard metrics hide. A restaurant might have high total revenue but poor RevPASH because it's running at low utilization for long hours. Or it might have good RevPASH at peak times but a severe drop during off-peak hours — suggesting an opportunity to run programming or promotions during those windows.
Metric #4: Table Turnover Rate
How many times does each table get used during service? For most casual and mid-range restaurants, 1.5–2.5 turns per table per service is healthy. Fine dining intentionally targets 1 turn. High-volume casual targets 3+.
Turnover rate is only valuable in context. A low turnover rate in a high-RevPASH restaurant might be perfectly intentional. The warning sign is a low turnover rate combined with a low RPT — it means tables are occupied for a long time without generating proportional revenue.
Metric #5: Net Profit Margin
After all costs — food, labor, overhead, debt service, everything — what percentage of revenue actually stays? This is your true north metric. Every other number on this list is a lever that moves this one.
| Restaurant Type | Average Margin | What to Aim For |
|---|---|---|
| Fast casual / QSR | 6–9% | 12%+ |
| Casual dining | 3–9% | 10%+ |
| Bar + restaurant | 10–15% | 20%+ |
| Fine dining | 6–10% | 15%+ |
Tracking All Five — Without the Spreadsheet
The challenge isn't knowing which metrics matter. It's building the habit of measuring them consistently. Most restaurant operators find monthly reviews too infrequent (problems compound) and daily reviews too granular to be actionable.
A weekly review of all five metrics — with a nightly log of the key inputs — is the cadence that gives early warning signals without creating analysis paralysis. The restaurants that build this habit in their first year tend to iterate faster, staff smarter, and survive longer.
