10 formulas for targets, expansion, and decisions

1. Weekly sales target = monthly target / operating weeks.
2. Daily target = weekly target / operating days.
3. Gap to target = target - actual.
4. Recovery needed = gap / remaining days.
5. Promotion ROI = incremental profit / promotion cost.
6. Equipment ROI = savings or incremental profit / investment.
7. Payback period = investment / incremental monthly cash flow.
8. Channel profitability = channel margin / channel sales.
9. Unit economics = average guest revenue - average variable cost.
10. Profitable capacity = max volume without breaking quality or margin.

Formulas do not replace judgment. They make judgment repeatable. That is the difference between a busy restaurant and a durable one.
