Quick Answer
Tip amount is calculated as Tip = Bill Amount × (tip percentage ÷ 100), and the total bill including tip is the original amount plus the tip; to split among multiple people, divide the total by the number of people.
What Is a Tip?
A tip calculator quickly works out how much gratuity to leave at a restaurant or for a service, and — when dining with others — how to split the total bill fairly among a group. Tipping norms vary significantly by country: in the United States, 15-20% is a common standard for restaurant service, while in many other countries, a smaller tip (or none, where service charges are already included) is customary.
Bill splitting introduces its own small complexities: splitting evenly is simplest, but groups often want to account for who ordered what, or whether to split based on the pre-tax or post-tax amount. Some calculators also handle uneven splits, where one person covers a different share than others.
Tip calculators remove the mental math and potential awkwardness of calculating percentages or per-person amounts at the table, especially for larger groups or unusual percentages.
How to Use This Tip
- 1Enter the total bill amount.
- 2Select or enter your desired tip percentage.
- 3Enter the number of people splitting the bill, if applicable.
- 4The calculator shows the tip amount, the total bill including tip, and the per-person amount if split.
The Formula Explained
Tip = Bill Amount × (tip% ÷ 100)Total = Bill Amount + TipPer Person = Total ÷ Number of PeopleExample: $86 bill, 18% tip, split between 4 people
- Bill Amount = $86, Tip % = 18%
- Tip = 86 × 0.18 = $15.48
- Total = 86 + 15.48 = $101.48
- Per Person = 101.48 ÷ 4
Tips & Things to Know
- Tipping customs vary widely by country — what's considered generous in one country may be unusual or even unnecessary in another, so it's worth knowing local norms when traveling.
- Some venues automatically add a service charge to the bill — check carefully before adding an additional tip on top, to avoid effectively double-tipping.
- For uneven group orders, splitting based on what each person actually ordered (rather than a flat even split) is fairer but requires itemizing — decide as a group which approach to use before calculating.
- Rounding the final per-person amount up slightly (e.g. to the nearest convenient note or coin) can make settling up in cash simpler for everyone.
