Why More Metrics Usually Means Less Control
It's tempting to track everything a modern POS and accounting system can produce. In practice, this produces the opposite of control: a report so dense that nobody reviews it consistently, and a business that finds out about a problem a quarter after it started rather than a week after. The operators with the best-run venues we've worked with typically track five to seven numbers closely, and everything else occasionally.
The Core Numbers That Actually Matter
| KPI | What it measures | Review cadence |
|---|---|---|
| Food cost % | COGS as a % of food revenue | Monthly deep-dive |
| Labour cost % | Total wage cost (incl. on-costs) as a % of revenue | Monthly deep-dive |
| Prime cost | Food cost % + labour cost % combined | Weekly |
| Average spend per head | Revenue ÷ covers served | Weekly |
| Seat turn / covers per seat hour | How efficiently the space is used | Weekly |
1. Food Cost Percentage
Cost of goods sold as a percentage of food revenue. Useful as a trend indicator against your own history rather than a fixed external target — see our detailed breakdown of food cost benchmarks by concept type for the ranges that apply to different venue types.
2. Labour Cost Percentage
Total wage cost (including on-costs) as a percentage of revenue. Like food cost, the right number depends heavily on concept and service model — our labour cost benchmark guide covers this in detail, including the metrics that matter more than the headline percentage, such as sales per rostered hour.
3. Prime Cost
Food cost plus labour cost, combined, as a percentage of revenue. This is the single most useful number in the entire report, because it captures the interaction between the two biggest controllable costs in the business. A well-run casual restaurant typically sits between 55% and 65% prime cost; above 68–70% signals structural pressure that needs attention beyond simple cost-cutting.
4. Average Spend Per Head
Total revenue divided by covers served. Tracked weekly, this is often the earliest indicator that something in the menu mix, upselling discipline or guest experience has shifted — well before it shows up in the bottom line.
5. Seat Turn / Covers Per Available Seat Hour
How efficiently the physical space is being used across a trading period. For venues with a fixed number of seats, this number — not just total covers — reveals whether the business is capacity-constrained or demand-constrained, which changes what should be done about slow growth.
The Reporting Rhythm That Makes These Numbers Useful
A KPI is only useful if it's reviewed on a rhythm that allows action before the problem compounds. In practice: prime cost and average spend should be reviewed weekly, ideally against the same day of the prior week rather than the prior month, to account for trading pattern differences. Food cost and labour cost in more granular detail — down to individual recipe or roster line — deserve a monthly deep-dive rather than a weekly one, since daily and weekly noise can obscure real signal at that level of detail.
The reporting cadence itself is often more important than the software used to produce it. A simple spreadsheet reviewed consistently every Monday morning outperforms a sophisticated dashboard that gets opened once a month.
Common KPI Mistakes We See
The most common mistake is benchmarking against industry averages instead of your own trend. An industry benchmark tells you whether you're in a reasonable range; your own history tells you whether something has actually changed in your business, which is the more actionable question. The second most common mistake is tracking a metric without a corresponding action threshold — knowing your food cost is 32% is not useful unless you also know at what number you would actually intervene, and what that intervention would be.
Our food cost calculator, labour cost benchmark tool and contribution margin calculator are built to make these specific numbers easy to check accurately and consistently, without needing a full reporting system to get a reliable read.
Building This Into a Reporting Habit
If your business doesn't currently have a consistent weekly numbers review, that's a more valuable first step than adding new metrics to an existing dashboard nobody checks. Our profit systems work is built around exactly this — establishing the small number of KPIs that actually matter for your specific concept, and the reporting rhythm that keeps them in front of the right person at the right time.
