How to Calculate a Tip
Tipping is customary in many countries, especially the United States, where service workers often depend on gratuities as a major portion of their income. This calculator makes it easy to determine the right tip amount for any situation.
The Tip Formula
Tip Amount = Bill × (Tip Percentage / 100)
Total = Bill + Tip
Per Person = Total / Number of People
Standard Tip Percentages
- 15% -- Acceptable for adequate service
- 18% -- Good for standard service
- 20% -- Standard for good service (most common)
- 25%+ -- For exceptional service
- 10% -- Buffet or counter service
Quick Tip Estimation Tricks
To quickly estimate a 20% tip: find 10% by moving the decimal point one place left, then double it. For an $85 bill: 10% = $8.50, doubled = $17.00 tip. For 15%, find 10% and add half of it: $8.50 + $4.25 = $12.75.
When to Tip More
Consider tipping above 20% for large groups, holidays, bad weather (delivery), complex orders, or when your server provided extraordinary service. Many restaurants automatically add 18-20% gratuity for parties of 6 or more.
