How to Calculate a Tip
To calculate a tip, multiply the total bill by the tip percentage (expressed as a decimal). For example, an 18% tip on a $50 bill is $50 × 0.18 = $9.00.
Tipping Etiquette
- Standard service: 15% - 18%
- Excellent service: 20% - 25%
- Large groups: Many restaurants add a 18% gratuity automatically.
