Key Restaurant Financial Metrics to Track
You can't manage what you don't measure. Here are the essential restaurant financial metrics — with formulas and targets — every owner should track.
The key financial metrics every restaurant owner should track are food cost percentage, labor cost percentage, prime cost, average check, sales per labor hour, revenue per seat, and net profit margin. Together they tell you whether you're pricing right, staffing right, and keeping enough of each dollar. Tracking them turns your restaurant from something you run by feel into something you run by numbers — and the numbers catch problems weeks before your gut does.
The core seven, with formulas and targets
| Metric | Formula | Healthy target |
|---|---|---|
| Food cost % | COGS ÷ food sales | 28–35% |
| Labor cost % | Total labor ÷ sales | 25–35% |
| Prime cost | (COGS + labor) ÷ sales | ≤ 60–65% |
| Average check | Total sales ÷ number of guests | Concept-specific |
| Sales per labor hour | Sales ÷ labor hours worked | Rising trend |
| Revenue per seat | Sales ÷ number of seats | Rising trend |
| Net profit margin | Net profit ÷ sales | 8–15% |
Track each as a percentage or ratio, not just a dollar figure, so you can compare a busy month to a slow one honestly.
Prime cost is the one to watch daily
If you only follow one number closely, make it prime cost — food plus labor as a share of sales. It combines your two largest and most controllable costs into a single health check. Keep it at or below 60–65% and profit usually follows; let it climb and no amount of volume saves you. Read understanding prime cost and why it matters for the full breakdown, and check it weekly, not monthly.
Prime cost is the restaurant owner's blood pressure. One reading is fine; it's the trend across weeks that tells you whether you're healthy.
The metrics that reveal efficiency
Food and labor percentages tell you about cost. Average check, sales per labor hour, and revenue per seat tell you about how hard your restaurant is working.
- Average check shows whether upselling and menu design are lifting spend. A rising check on flat traffic means your menu is selling harder.
- Sales per labor hour shows whether you're scheduled to demand. Low numbers mean overstaffing; painfully high numbers mean guests are waiting.
- Revenue per seat shows how well you're using your physical space, tying together pricing, turnover, and traffic.
Where the data comes from
You can't track what you can't see, and metrics are only as fresh as your reporting. Pulling COGS from invoices, labor from your time clock, and average check from sales by hand is slow enough that most owners give up. A POS that reports daily does the collecting for you. Cobblestone POS surfaces sales, average check, labor cost, and sales-per-labor-hour on a live dashboard — and its AI assistant, Daisy, can hand you a morning briefing on yesterday's numbers — so you read your metrics with coffee instead of reconstructing them at month-end. Compared with paying $470+/month for a legacy system that still nickel-and-dimes reporting as an add-on, it's free.
Turn metrics into decisions
Numbers you look at but never act on are just decoration. Set a target for each metric, review the actuals on a fixed schedule, and when one drifts, trace it to a cause. Food cost up? Check waste, portioning, and vendor prices. Labor up? Check the schedule against your sales forecast. Average check down? Look at menu mix and server upselling. Pair these metrics with your P&L and a budget, and you have a complete instrument panel — one that tells you where you are, where you're headed, and which lever to pull next.
