Work out how much to tip, your total bill with tip, or how to split it among a group — pick what you're solving for below.
Quick answers to the questions people ask most about tipping.
Multiply the bill amount by the tip percentage as a decimal. A 20% tip on a $50 bill is $50 × 0.20 = $10.
Add the tip to the bill to get the total, then divide that total by the number of people. A $50 bill with a 20% tip is $60 total, split 4 ways is $15 each.
In the US, 15-20% is typical for restaurant table service, with 20% common for good service. Tipping norms vary significantly by country and by service type, so check local customs when traveling.
Tipping on the pre-tax amount is generally considered standard etiquette, though tipping on the post-tax total is also common and not considered wrong — it usually only changes the tip by a small amount.
