Tipping Etiquette in the US: What's Actually Expected
In the US, 15–20% is the standard tip range for restaurant table service, with 18–20% typical for good service — tipping below 15% is generally read as a signal of dissatisfaction. Delivery, bartending, and personal services each have their own norms, usually in the 10–20% range or a flat per-service amount.
Tipping norms in the US aren't written down anywhere official, which is exactly why they cause so much quiet uncertainty — at the table, on a delivery app, and especially when a group is splitting a bill unevenly.
Restaurant tipping: what the range actually means
15% is broadly understood as acceptable for standard service, 18–20% signals good service, and 20%+ is for service that went noticeably above expectations. Because many US service workers are paid a lower base wage on the assumption that tips make up the difference, tipping below 15% is generally read as dissatisfaction rather than a neutral choice.
Some restaurants now add an automatic service charge or gratuity, especially for large parties — check the receipt before tipping on top, since tipping again on an already-included gratuity is a common and easy mistake to make.
Delivery, bars, and other common situations
Food delivery typically runs 15–20% of the order, or a $3–5 flat minimum for smaller orders, especially in bad weather or for longer distances. Bartenders are commonly tipped $1–2 per drink or 15–20% of the tab. Hair stylists, cab and rideshare drivers, and hotel staff each have their own softer norms, generally in the 10–20% range or a small flat amount per service.
Splitting a tip fairly in a group
The simplest approach — splitting the total bill and tip evenly — works well when everyone ordered similarly. It breaks down when one person had an appetizer, a drink, and dessert while another had a side salad, which is where a fair split needs to weight each person's actual order rather than dividing everything equally.
The Bill & Rent Splitter and Tip Calculator handle both cases: an even split for simple situations, or a weighted split when contributions genuinely differ.
