Tipping in the United States: restaurants, service charges, and simple percentages

In the United States, restaurant tipping is part of the normal dining routine. It is also one of the places where travelers feel the most pressure, because the expected amount is usually a percentage rather than a small round-up.

The short version: for a sit-down restaurant with table service, many diners use 18–20% as a normal range. A lower tip may be read as a signal that something went wrong. A higher tip is common for excellent service, complicated orders, or a large group.

Quick answer

Situation	Practical amount
Full-service restaurant	18–20%
Excellent service	20%+
Poor service	Lower, but consider whether the issue was the server’s fault
Counter service	Optional; small amount or no tip depending on the setup
Automatic gratuity added	Usually no extra needed

If you want to avoid mental math, enter the bill and percentage in the tip calculator and adjust the number of people if you are splitting.

Should you tip before or after tax?

Many people calculate tips on the pre-tax amount. Others use the final total because it is simpler. If you are trying to be precise, use the pre-tax food and drink subtotal. If you are traveling and want a quick answer, using the final total is usually close enough.

Watch for automatic gratuity

Some restaurants add a service charge or automatic gratuity, especially for large parties. Read the bill before adding another tip. If the bill says 18% gratuity has already been included, you normally do not need to add more unless you want to.

Counter service and tablets

The United States has many payment screens that ask for tips at coffee shops, bakeries, takeout counters, food trucks, and casual restaurants. These prompts can feel awkward. For counter service, tipping is more optional than at a sit-down restaurant. A small amount is appreciated, but you are not using the same rule as table service.

Splitting a bill

If everyone ordered roughly the same amount, split the total after tip. If one person ordered much more, calculate that person’s share first and then divide the remaining amount. For groups, it is usually easier to agree on the percentage before calculating.

Bottom line

In the United States, assume that a sit-down restaurant tip is part of the bill unless a service charge is already included. If the service was normal and you are unsure, 18–20% is a safe modern range.

Common mistakes

The biggest mistake is treating every American payment screen like a restaurant bill. A tablet at a coffee counter may ask for 20%, but that does not mean the social expectation is the same as a server taking care of your table for an hour. Another mistake is tipping twice when an automatic gratuity has already been added for a group.

If service was genuinely bad, you can leave less, but try to separate slow food, kitchen problems, or understaffing from the server’s effort. If the server handled a difficult situation well, the tip often still reflects that.

Traveler note

For budgeting, add restaurant tips to your meal estimates before the trip. A $25 menu item can become noticeably more expensive once tax and tip are included, especially in cities with higher sales tax.
