US Tip Calculator

What Is the Tip Calculator?

The Tip Calculator is a free browser-based tool that computes the appropriate gratuity amount and splits the total bill among any number of people. Unlike generic calculators that apply a flat percentage, this tool incorporates regional tipping customs across the United States — from the typical 20% standard in New York City restaurants to the 18% baseline common in California — and lets you adjust for service quality. It handles edge cases like splitting unevenly across a party, rounding to whole dollar amounts, and adding separate tip lines for large groups where gratuity may or may not already be included. All processing runs locally in your browser; no bill data is ever transmitted to a server.

Who Should Use This Tool?

This tool is designed for diners splitting a restaurant check among friends or colleagues who need a quick, accurate tip and per-person total. Travelers visiting a new city use it to look up local tipping norms — whether 15% suffices at a casual diner or 25% is expected at an upscale establishment. Rideshare passengers use it to calculate driver tips based on fare amount. Event hosts organizing group dinners rely on it to pre-calculate gratuity for large parties where auto-gratuity policies vary by venue. Bartenders and service industry workers also use it to verify that split-tip pools are divided correctly at the end of a shift.

How to Use the Tip Calculator

Enter your pre-tax bill total into the input field and select your party size. The tool defaults to a region-appropriate tip percentage based on your selection (or you can enter a custom percentage). Results update instantly as you type, showing the tip amount, total bill including tip, and per-person share. Use the round buttons to round each person's share up or down to the nearest dollar — useful when splitting cash payments. For large groups, the tool flags whether the restaurant is likely to add an automatic gratuity (typically 18% for parties of 6 or more) so you avoid double-tipping. All calculations are performed in your browser; close the tab and your data is erased.
