About the Tip & Bill Split Calculator
Split a restaurant bill, service tip or shared cost across a group with a transparent per-person total.
Formula or method
Round the bill to cents, calculate and round the tip, then split the total. If cents are left over, assign one extra cent to each of that many people.
Worked example
A 100.00 bill with a 20% tip totals 120.00. Four people pay 30.00 each. Splitting 100.00 with no tip three ways gives two shares of 33.33 and one of 33.34.

Assumptions and limitations
This tool assumes equal shares and calculates tips on the bill entered. Some venues calculate tips before tax; split individual items separately.
Frequently asked questions
Should a tip be calculated before or after tax?
Conventions vary. Enter the amount on which you want to apply the tip, and check the venue's policy.
