In the United States, the standard tip at a sit-down restaurant is 15–20% of the pre-tax bill. 15% is acceptable for average service, 18–20% for good service, and 20–25% or more for exceptional service. For takeout, tipping is optional but 10% is appreciated.

It is generally more common in the US to tip on the pre-tax amount, though many people tip on the total bill for simplicity. The difference is usually small. This calculator uses the bill amount you enter, so simply type in whichever amount you prefer to tip on.

This calculator splits the total bill (including tip) equally among all people. Set the number of people using the + and − buttons, and the “each person pays” amount will update automatically. Note that this assumes an equal split — it does not account for individual item differences.

In most countries, tipping is voluntary and based on your satisfaction with the service. However, in some US restaurants, an automatic gratuity (usually 18–20%) may be added to large group bills. Always check your bill before adding an additional tip to avoid double-tipping.

Yes. The calculator shows the $ symbol by default but the math works for any currency. Simply enter your bill amount in your local currency and interpret the results in that same currency. The percentage-based calculation is universal regardless of currency.
