What is Tipping?

Tipping is the practice of giving a gratuity to service workers, typically in restaurants, hotels, and other service industries. It's a way to show appreciation for good service and supplement the income of service workers who often rely on tips as a significant portion of their earnings.

Key Aspects of Tipping:

  • Gratuity: Voluntary payment for service
  • Service Recognition: Acknowledgment of good service
  • Income Supplement: Additional earnings for service workers
  • Cultural Practice: Varies by country and culture

Understanding tipping culture and proper etiquette helps ensure you're being fair to service workers while following social norms in different situations and locations.

Calculation Methods

Basic Tip Calculation

Standard formula for calculating tips:

Tip Amount:
Tip = Bill Amount × (Tip % ÷ 100)
Example: $50 × (20 ÷ 100) = $10
Total Amount:
Total = Bill Amount + Tip
Example: $50 + $10 = $60
Per Person (if splitting):
Per Person = Total ÷ Number of People
Pre-Tax vs Post-Tax

Whether to tip on pre-tax or post-tax amount:

Pre-Tax (Recommended)
Tip on the subtotal before taxes
More fair to service workers
Post-Tax (Common)
Tip on the total including taxes
Easier to calculate from receipt
