Restaurant KPIs: The Numbers Every Operator Should Track Weekly
The difference between restaurant operators who always know where they stand and those who get surprised by their monthly P&L comes down to one habit: weekly measurement. Track the right numbers every week and problems are caught while they're still small. Don't track, and you find out when it's already expensive to fix.
Here are the six numbers every restaurant should track every single week.
1. Weekly revenue
Pull total revenue from your POS every week, broken down by day and ideally by category — food, beverages, and any other revenue streams. You're looking for trends: is Tuesday lunch weaker than it was two months ago? Has the Friday dinner period been growing? Revenue by day and category tells you where your trading patterns are shifting before they show up in a monthly summary.
Compare each week to the same week last year if you have the data. Seasonality is real and context matters — a 10% drop in the second week of January may be normal; the same drop in mid-October may not be.
2. Food and beverage cost percentage
Total food and beverage costs for the week divided by total food and beverage revenue. This is your most important product cost metric and the one most directly within your control.
Target: 28–35% of revenue. Above 35% means your menu isn't priced correctly, your portions aren't controlled, or you have a waste problem — possibly all three.
Calculate it from your actual supplier invoices for the week, not from a theoretical percentage. The difference between your theoretical and actual food cost is one of the most useful numbers in restaurant management — it reveals waste, theft, and portioning errors that would otherwise be invisible.
3. Labour cost percentage
Total wages paid in the week divided by total revenue. Include all staff — kitchen, front of house, management — and if you're working in the business, include a market-rate salary for your role even if you're not drawing it formally.
Target: 28–35% of revenue. Break it down by department — kitchen vs front of house — so problems are visible at the source rather than hidden in a blended number.
Labour is the easiest cost to overspend and the hardest to cut once staff are rostered and accustomed to their hours. Catching a 2% drift above benchmark in week three is fixable. Finding out in the month-end P&L that labour has been running at 38% for six weeks is a much harder conversation.
4. Prime cost
Food and beverage cost plus labour cost as a percentage of revenue. This single number tells you more about your restaurant's financial health than any other metric. It's the combined cost of your two largest and most controllable expenses.
Target: Under 65% of revenue. The best-run restaurants keep prime cost under 60%. Above 70% means profitability is structurally very difficult regardless of how well you manage everything else.
Prime cost is the number experienced operators look at first, every week, without exception. If it's on target, the business is likely healthy. If it's drifting, that drift needs an explanation and a correction before the next week starts.
5. Covers and average spend per head
How many customers did you serve, and what did they spend on average? These two numbers explain your revenue. If revenue dropped, was it because you served fewer people, or because each person spent less? The answer points to different solutions.
Declining covers suggests a traffic or loyalty problem — something is keeping customers away or not bringing them back. Declining average spend suggests customers are ordering less — fewer starters, fewer desserts, fewer drinks. Both are worth tracking and both require different responses.
Your POS system can provide both numbers. If it doesn't, it's worth configuring — covers and average spend are among the most actionable metrics in the business.
6. Labour hours vs covers ratio
Total hours worked divided by total covers served. This is a more granular way to understand labour efficiency than the cost percentage alone, because it separates the volume question from the wage rate question.
If your labour cost percentage is rising but your hours-per-cover ratio is stable, the problem is wage rates — award increases, penalty rates, or a shift in your staff mix toward more expensive positions. If your hours-per-cover ratio is rising, you're using more labour per customer — overstaffing, slower service, or a change in your menu complexity.
Knowing which problem you have is the first step to fixing it.
How to track these without spending hours
A simple weekly spreadsheet with six rows — updated every Monday morning using your POS and payroll data — takes 15 minutes. That 15 minutes is the highest-return financial habit in restaurant management. It turns month-end surprises into weekly early warnings, and early warnings are fixable. Month-end surprises often aren't.
| KPI | Target | Warning sign | Source |
|---|---|---|---|
| Weekly revenue | Growing or stable | Declining trend | POS system |
| Food & bev cost % | 28–35% | Above 35% | Supplier invoices |
| Labour cost % | 28–35% | Above 35% | Payroll system |
| Prime cost | Under 65% | Above 70% | Calculated |
| Average spend per head | Stable or growing | Declining trend | POS system |
| Labour hours per cover | Stable | Rising trend | Roster + POS |
The operators who know these numbers cold — who can tell you their prime cost for the past three weeks without looking it up — are almost universally the ones running profitable businesses. It's not a coincidence. Financial awareness creates financial discipline, and financial discipline creates margin.
