How Do You Calculate Tax and Tip?
Work out the tax and the tip separately, then add both to the bill. Most people tip on the pre-tax subtotal: on a $50 bill with 8% tax, a 20% tip is $10 and the total is $64. Tipping on the after-tax total makes the tip $10.80 instead. For US table service, 18-20% is standard, 15% for average service and 22-25% for excellent service.

In the United States, 18-20% is standard for restaurant service. Use 15% for average service and 22-25% for excellent service.
