Open toolCalculators
Enter the bill, pick a tip percentage, and split the total fairly between any number of people.
Good to know
Tip amount = bill × tip percentage ÷ 100. The total is the bill plus the tip, and the per-person amount divides the total by the group size.
Customs vary. Enter whichever bill amount you prefer to tip on — the calculator works with exactly the number you type.
It increases the tip slightly so the final total is a whole number, which is convenient when paying in cash.
