What prime cost should include
For most independent restaurants, weekly prime cost should include food COGS, beverage COGS, and total labor. Keep the definition stable so period-over-period movement is trustworthy.
Labor should include wages, overtime, and usually salaried management allocated to the week. If tips or service charges change your labor picture, document the rule and keep it consistent.
- Food purchases adjusted for beginning and ending inventory
- Beverage purchases adjusted for inventory when material
- Hourly labor + overtime for the same sales week
- Manager salaries allocated to the operating week
A weekly operating cadence that works
Pick one close day — many operators use Monday or Tuesday for the prior week. Pull sales, purchases, inventory counts, and timecards into one review package.
Do not wait for a perfect accountant-ready P&L. The point of weekly prime cost is operator speed: see movement, ask why, assign a fix.
- Lock the sales week and export POS totals
- Enter or import purchases and waste
- Post inventory counts for high-variance categories
- Compare scheduled versus actual labor hours and dollars
- Write three notes: what moved, why, and next action
Targets and red flags
Targets vary by concept, but independents usually watch prime cost as a band, not a single magic number. Full-service concepts often live in a different range than fast casual or high-volume beverage programs.
Red flags are sudden jumps without a sales explanation, rising labor with flat covers, food cost climbing while menu mix is stable, or one location drifting while peers stay flat.
When spreadsheets stop being enough
A Google Sheet can run the first version of this process. It breaks when counts, permissions, multi-location rollups, and manager accountability become fragile.
That is the point where a custom prime cost dashboard or owned P&L system pays for itself: controlled inputs, clearer ownership, and AI-assisted notes on what moved.
