Tipping Guide
- Restaurants: 15-20% of the pre-tax bill
- Delivery: 15-20% (minimum $3-5)
- Bartender: $1-2 per drink or 15-20% of tab
- Hair stylist: 15-20%

Formula
Tip = bill × tip percentage. Total = bill + tip. Split = total ÷ number of people. Tax is typically calculated on the pre-tip subtotal, and tip on the pre-tax amount, though customs vary.
Worked Example
A $60 bill, a 20% tip, split 3 ways.
- Bill
- $60
- Tip %
- 20%
- People
- 3
- Result
- $24 per person
Tip = $60 × 0.20 = $12. Total = $72. Split 3 ways = $24 each.
