Tip Calculator
Tipping in the U.S. is built into how service workers earn a living — 18%–22% in sit-down restaurants is standard, with 20% the default most people aim for. This calculator works out the tip, splits the total between any number of diners, and warns when an auto-gratuity has already been added (common for parties of six or more).
How is this calculated?
Tip = bill × tip percentage. Most diners tip on the pre-tax subtotal as a matter of math purity, but tipping on the post-tax total is also common and adds only a few cents per dollar of tax — your call. If an auto-gratuity is already on the bill (typically 18%–20% for parties of 6 or 8+), the calculator subtracts it from the subtotal before applying any additional tip you choose. The total is then divided evenly between diners. Rounding up to the nearest dollar is a common option.
Frequently Asked Questions
How much should I tip in U.S. restaurants?
18%–22% for sit-down service is the current standard, with 20% the default most diners use. 15% is increasingly seen as low. For exceptional service, 25%+. Counter service tipping is more discretionary — leaving the change or a few dollars is appreciated but not strictly expected.
Should I tip on the pre-tax or post-tax total?
Mathematically, pre-tax is the purist answer because tax isn't a service the server provided. Practically, most people tip on the post-tax total — the difference is usually a couple of dollars and the server doesn't mind. Either is acceptable; what matters is that you tip something fair on the food and drink portion.
What about delivery, ride-share, hairdressers, and bars?
Delivery: 15%–20% or $5 minimum. Ride-share: 15%–20% in the app. Hairdressers and barbers: 15%–20% to your stylist. Bars: $1–$2 per drink, or 20% on a tab. Hotel housekeeping: $3–$5 per night. Valet: $2–$5 on retrieval. Skycaps: $2 per bag.
Is auto-gratuity actually mandatory?
If it's clearly disclosed on the menu (typically for parties of 6 or 8 or more), it's contractually part of your bill and you owe it. You can ask for it to be adjusted in cases of genuinely poor service but most places enforce it as written. Always check the bill before adding an additional tip — double-tipping is common.
