How to use (weekly, 10 minutes)

Fill in the Inputs table (sales, COGS, labour).
Review the Results table (food %, labour %, prime %).
If any Flags trigger, follow the Diagnosis prompts.
Write one decision for next week.

Inputs (fill-in)

Week start	Total revenue	Total COGS	Total labour cost	Labour hours (optional)	Notes (events/promos/closures)

Results (auto-calc)

Food cost %	Labour %	Prime cost %	Revenue per labour hour (optional)

Formulas (for spreadsheet)

Food cost % = COGS ÷ revenue
Labour % = labour cost ÷ revenue
Prime cost % = (COGS + labour cost) ÷ revenue
Revenue per labour hour = revenue ÷ labour hours

Flags (what to investigate first)

🚦

Trigger a deep check if ANY of these happen:

Prime cost % up > 3 points week-on-week
Labour % up while revenue is flat/down
COGS up while revenue is flat

Diagnosis prompts (copy/paste)

If FOOD COST % is up

Did supplier prices change this week?
Any portioning drift (new staff / no scale / “extra” scoops)?
More waste/spoilage? What items?
Delivery mix increased (commissions/packaging affecting margin)?
Any promo/discount affecting perceived cost %?

If LABOUR % is up

Roster mismatch vs demand (slow periods overstaffed)?
Overtime or last-minute coverage?
Slow service causing fewer covers (sales down, labour constant)?
Training gaps causing rework / ticket time delays?
