How to Split a Restaurant Bill

Step 1: Enter the total bill amount (before tip)
Step 2: Choose your tip percentage — common options are 15%, 18%, or 20%
Step 3: Enter the number of people splitting the bill
Step 4: Add any discounts or extra charges (optional)
Step 5: Click "Split Bill" to see each person's share

US Restaurant Tipping Guide

In the United States, tipping is customary for good service. Here are standard tipping guidelines:

15-20%: Standard tip for good service at restaurants
18-20%: Common for parties of 6 or more (automatic gratuity)
20-25%: For exceptional service or fine dining
10%: For buffet-style or takeout orders
$1-2 per drink: For bartenders

When to Split Bills Evenly vs. Itemized

Even split: Best when everyone shares food family-style or orders similar priced items
Itemized split: Better when one person orders significantly more expensive items or alcohol
Pay separately: Many restaurants now offer individual checks — just ask your server!
