About Online Tip Calculator

Online Tip Calculator is a free, browser based tool that helps you calculate tip, total and per person amounts in seconds. It was built to be fast, private and easy to use on any device, without signups or app installs.

Our purpose

We wanted a simple tip calculator that works for everyday situations, from restaurant bills to food delivery and group dinners. The goal is to reduce mental math, avoid rounding errors and make it simple to split the bill fairly. The tool does not track you or store your amounts. Everything runs locally in your browser.

Whether you want to calculate tip for a small cafe bill or split a larger group total, the calculator gives you clear results you can act on right away. Try it on the homepage tip calculator.

How the tool works

The calculator uses standard math: tip equals bill multiplied by tip percentage divided by 100, and total equals bill plus tip. When you enter a number of people, the tip and total are divided equally to show per person tip and per person total. The currency selector formats the numbers using Intl.NumberFormat, so symbols and decimals match your chosen currency.

An optional round up toggle rounds the total to the next whole unit and adjusts the tip so the numbers stay consistent. No data leaves your device. You can read more in our Privacy Policy.
