FAQ

What is the standard tip percentage in the US?

In the United States, the standard tip for sit-down restaurant service is 15-20% of the pre-tax bill. 15% is considered acceptable for adequate service, 18% for good service, and 20% or more for excellent service. Tipping customs vary by country, so check local norms when traveling.

Should I tip on the pre-tax or post-tax amount?

Traditionally, tips are calculated on the pre-tax bill amount. However, many people tip on the post-tax total for simplicity. The difference is usually small. For a more generous tip, calculate on the post-tax amount.

Is it okay to tip less than 15%?

While tipping is technically optional in the US, it's important to know that many service workers rely on tips as a significant portion of their income. Tipping less than 15% is generally reserved for notably poor service. If service was truly unsatisfactory, consider speaking with management.

How do I calculate tip quickly in my head?

Quick mental math tricks:

  • 10%: Move the decimal one place left ($45.00 → $4.50)
  • 20%: Calculate 10% and double it ($4.50 × 2 = $9.00)
  • 15%: Calculate 10% plus half of that ($4.50 + $2.25 = $6.75)
  • 18%: Calculate 20% minus a little (roughly $9.00 - $0.90 = $8.10)
Should I tip on alcohol at restaurants?

Yes, alcohol is typically included in the tip calculation at restaurants where drinks are served as part of your meal. At bars, it's common to tip $1-2 per drink or 15-20% of the bar tab.

What if service was included in the bill?

Some restaurants add a service charge (often 18-20%) automatically, especially for large groups. Check your bill carefully - if gratuity is already included, you don't need to tip additional unless you want to reward exceptional service.

Methodology

The tip calculation is straightforward:

Basic Formula:

  • Tip Amount = Bill Amount × (Tip Percentage / 100)
  • Total = Bill Amount + Tip Amount

Per Person:

  • Total Per Person = Total / Number of People
  • Tip Per Person = Tip Amount / Number of People

Round Up:
When enabled, the total is rounded up to the nearest whole dollar, and the tip amount is recalculated as the difference between the rounded total and the original bill.
