How to use this calculator
Enter the amount you want to use as the tip base. Check whether the bill already includes a service charge.
The rate is your choice; the calculator does not assume local customs. Rounded shares may leave a cent to allocate when paying the bill.
The formula
Tip = bill × tip percentage ÷ 100. Total = bill + tip. Per person = total ÷ people.
A worked example
A bill of 75 with a 15% tip adds 11.25, totaling 86.25. Split three ways, each share is 28.75.
