The Correct Math (with Food Cost Included)
Many examples online simply divide monthly costs by the ticket price. That’s wrong because ingredients (food cost) come out of every sale.
The right way is to use contribution margin per customer:
Food Cost % (f) — benchmark ≈ 35%
Contribution per customer = P × (1 − f)
Fixed Costs (F) = staff + general expenses
Profit Goal (G) = what the owner plans to earn this month (set first)Math for Restaurants
Customers needed = (F + G) ÷ [ P × (1 − f ) ]
