Frequently Asked Questions

First, calculate the tip amount by multiplying the bill by the tip percentage. Add the tip to the bill to get the total. Then divide the total by the number of people. For example: $100 bill, 18% tip, 4 people. Tip = $18, Total = $118, Each person pays $29.50.

It's standard to calculate the tip on the total bill before splitting. This ensures everyone pays an equal share of the tip. This calculator follows that approach — tip is applied to the full bill, then the total is divided evenly.

In the United States, standard tip percentages are 15% for average service, 18% for good service, and 20% or more for excellent service. In many other countries, tipping is not expected or is lower (5-10%). This calculator lets you set any tip percentage.

This calculator splits the bill evenly among all people. For uneven splits (where some people ordered more), you would need to calculate each person's share of the subtotal separately, then divide the tip proportionally. For a quick even split, this tool is perfect.
