How much should I tip in the US?
- Sit-down restaurants: 15–20% is standard; 20%+ for excellent service.
- Delivery: often 10–20%, more for long distances or bad weather.
- Hair and beauty: commonly 15–20%.
- Counter service and takeout: optional; many people leave 10% or round up.
These are customs, not rules — tipping norms vary by region and service.
Should I tip on the pre-tax or post-tax amount?
Tipping on the pre-tax subtotal is the traditional approach and slightly lower; tipping on the total is simpler and a little more generous. Enter whichever amount you prefer as the bill.
How to calculate a tip
- 1Take the bill amount (many people use the pre-tax subtotal).
- 2Multiply by the tip percent as a decimal: 20% → 0.20.
- 3Add the tip to the bill for the total.
- 4To split, divide the total by the number of people.

Frequently asked questions
What is 20% of a $50 bill?
$10. Move the decimal one place left for 10% ($5) and double it.
How do I split a bill with a tip?
Add the tip to the bill and divide by the number of people. With rounding on, each share is rounded up to a whole dollar, and the extra goes to the tip.
Is the service charge the same as a tip?
Not always. Some restaurants add a service charge or automatic gratuity for large groups. Check the bill before adding another tip.
