What is it?
The Split Bill Calculator divides a restaurant or group bill evenly among any number of diners, automatically computing the tip and adding it to each person's share. It removes the awkward mental math at the table and ensures everyone pays their fair share.
How to use
Enter the total pre-tip bill amount, drag the tip slider to your desired percentage (15%, 18%, and 20% are the most common in the US), and enter the number of people splitting the bill. The calculator instantly shows the tip, the full total, and each person's share.
Example scenario
A group of 4 friends has a $120 dinner. With an 18% tip ($21.60), the total is $141.60, so each person pays $35.40. The calculator confirms this in seconds — no phone calculator fumbling required.
Pro tip
In the US, tipping norms are: 15% for adequate service, 18% for good service, 20% for excellent service, and 25%+ for outstanding. Some restaurants automatically add a "service charge" for large parties (usually 6+) — always check your bill before adding a second tip. The convention of rounding up to the nearest dollar keeps cash transactions simple and leaves a slightly larger tip.
