Plenty of restaurants are busy and still lose money. The National Restaurant Association’s 2026 research, as reported by Restaurant Business, found that only 42% of US operators said they were profitable the previous year. Being full is not the same as being healthy.

The managers who stay ahead look at a small set of numbers every week, spot problems early and act before they grow. Here are the ones that matter most.

1. Sales against target

Compare this week’s sales with the same week last year and with your budget. Look at covers and average spend separately: falling covers is a marketing or reputation problem, while falling spend is a menu or service problem.

2. Food cost percentage

The cost of food used divided by food sales. A rise of a point or two is worth investigating immediately. Our earlier article on food cost percentage walks through the calculation.

3. Labour cost percentage

Wages and related costs divided by sales. Labour is usually your biggest controllable cost. Compare it with your roster: were you overstaffed on quiet shifts or understaffed on busy ones?

4. Average spend per head

Total sales divided by covers. This reflects menu design, pricing and how well your team recommends. It is the number most directly affected by service training.

5. Stock variance

The gap between what you should have used according to sales and what you actually used according to your count. This is where waste, theft and over-portioning show up. Our Inventory Management course sets out a practical counting system.

6. Guest feedback

Reviews, complaints and compliments. Not a financial number, but a leading indicator: service problems show up in reviews weeks before they show up in sales.

7. Staff turnover

How many people left this month? Each leaver costs you in recruitment, training and mistakes. A rising number is an early warning about management or morale.

Make it a routine

Pick the same day each week, use the same one-page report, and spend thirty minutes with it. Circle anything that has moved. For each circled number, write one action and one owner. Next week, check whether the action worked.

The discipline matters more than the spreadsheet. A simple report read every week beats a sophisticated one read every quarter.

Build the skills

Many managers were promoted for being good with guests, not good with numbers. That is a training gap, not a talent gap. Our Financial Management course teaches managers to calculate and act on these figures, and it is part of Executive Restaurant Management Programme alongside stock control and leadership.

Choose three of these numbers and check them this Friday. Then check them again next Friday.
