What Are Restaurant KPIs? The Numbers That Actually Run Your Business

You're losing money somewhere in your restaurant right now. Maybe it's $340 a week in food waste. Maybe it's $1,100 a month in labor creep from late clock-outs. If you're not tracking KPIs, you won't know which one, and you can't fix what you can't see.

A restaurant KPI (key performance indicator) is a specific number, tracked on a set schedule, that tells you whether a part of your operation is healthy or bleeding. Not a vibe. Not "the shift felt busy." A number, compared against a target, checked often enough to catch a problem before it shows up as a bad month on the P&L.

The Six KPIs That Actually Run a Restaurant

Most lists online give you twenty or more metrics and call it thorough. That's not useful, it's noise. Here are the six that catch the failures that actually sink independent restaurants, in the order to build the habit of checking them.

1. Prime Cost

Your cost of goods sold plus your labor cost, as a percentage of sales. This is the single number that tells you whether the business can survive. Target range: 55 to 60 percent for full-service, tighter for QSR, looser for bar-forward concepts. Full breakdown, formulas, and concept-specific benchmarks: the Prime Cost Guide.

2. Food Cost Percentage

What you paid for the ingredients on a plate, divided by what you sold that plate for. Track it weekly, not monthly, a monthly number is already four weeks stale by the time you see it. See the Food Cost Percentage Formula for why most operators calculate this wrong.

3. Labor Cost Percentage

Total labor spend, divided by sales, for the same period. A restaurant running 3 points over its labor target on $45,000 in weekly sales is bleeding $1,350 a week, every week, until someone catches it. The Restaurant Labor Cost Playbook covers the full breakdown by role and shift.

4. Comp and Void Rate

Total dollar value of comps and voids, divided by gross sales. A rate creeping past 2 percent without a documented reason on each ticket is either a training gap or a theft signal, and you won't know which until you're actually tracking it line by line.

5. Covers Per Labor Hour

Total guests served, divided by total labor hours worked that shift. This is your speed-of-service and staffing-efficiency number in one metric, and it's concept-specific: a bar-forward room and a fast-casual counter should never be compared against the same target.

6. Table Turn Time (FSR) or Ticket Time (QSR/Bar)

How long a table or ticket occupies capacity you could be reselling. A 15-minute drag on turn time across a 120-seat dining room on a Friday night is real revenue you never got a chance to make, not just a service complaint.

The Math That Makes This Real

Say your labor is running 34 percent against a 31 percent target, on $40,000 in weekly sales. That's 3 points of variance. Three points of $40,000 is $1,200 a week, every week, until it's caught and fixed, $62,400 a year. That's not a rounding error. That's the difference between a restaurant that survives a slow season and one that doesn't.

How Often to Check Each One

Prime cost and food cost: weekly, minimum. Labor cost: daily, ideally at the end of every shift, before the numbers go cold. Comps and voids: nightly. Covers per labor hour and turn time: per shift, especially on your highest-volume nights. Waiting for the monthly P&L to catch a labor problem means you've already lost a month of margin before you even see it.

Run the numbers before you set the price, and run them before the month ends, not after.

What to Do Next

If you're tracking these six by hand in a notebook or a spreadsheet you rebuild every week, you already know how much time that costs and how easy it is to fall behind. The Daily KPI Tracker builds all six into one weekly workbook with the formulas already correct, no rebuilding required.
