Should a tip be calculated before or after tax?

Tipping on the pre-tax subtotal is the more traditional convention, since tax is not part of what the server provided. Many people simply tip on the full receipt total including tax for simplicity.

Q: What's a standard tip percentage?

In the United States, 15 to 20 percent is typical for full-service restaurants, with 18 to 20 percent common for good service. Tipping norms vary significantly outside the US.

Yes, entering a number of people divides the total, bill plus tip, evenly across everyone. It does not account for people ordering different amounts.

Calculate the tip

Tip amount
Total (bill + tip)
Per person

How this is calculated

The tip is your bill multiplied by the tip percentage, and the total is the bill plus that tip. When splitting between multiple people, the total is divided evenly — this tool doesn't currently support splitting unevenly by what each person ordered, just a straight even split.

Tip on pre-tax or post-tax?

Common etiquette in the US is to tip on the pre-tax subtotal, though many people simply tip on whatever total is printed on the receipt (which usually includes tax) for simplicity. Enter whichever bill amount you intend to tip on — this tool doesn't assume one or the other.

Frequently asked questions

What's a standard tip percentage?

In the US, 15-20% is typical for full-service restaurants, with 18-20% common for good service. 15% or less is sometimes used for below-average service, and 20-25% for exceptional service or large groups. Tipping norms vary significantly outside the US.

Should I tip before or after tax?

Tipping on the pre-tax subtotal is the more traditional convention, since tax isn't part of what the server actually provided. In practice, many people just tip a round percentage on the full receipt total, including tax, since the difference is usually small.

Does splitting the bill divide it evenly?

Yes — entering a number of people divides the total (bill plus tip) evenly across everyone. It doesn't account for people ordering different amounts; for that, split the bill by item first, then use this tool per person's own subtotal.
