How to Calculate Tips and Split Bills

Calculating tips is a routine part of dining out in the United States and many other countries. While tipping customs vary around the world, in the US, a tip of 15-20% of the pre-tax bill is standard for restaurant service, with 18% being the most common baseline. Knowing how to quickly calculate the right tip amount — and split it among a group — eliminates awkward moments and ensures you leave an appropriate gratuity.

The tip calculation is straightforward: multiply the bill amount by the tip percentage divided by 100. For example, an 18% tip on a $50 bill is $50 times 0.18, which equals $9, making the total bill $59. When splitting among multiple people, simply divide the total by the number of diners. Our calculator handles all of this instantly, so you can focus on enjoying the meal instead of doing math on your phone.

Tipping customs extend beyond restaurants. In the US, it is customary to tip hairdressers (15-20%), taxi and rideshare drivers (15-20%), hotel housekeeping ($2-5 per night), and food delivery drivers (15-20%). Some establishments include a service charge automatically for large groups, typically 18-20%. Always check your bill before adding a tip to avoid double-tipping. This calculator works for any tipping scenario where you need to compute a percentage of a total.
