Terms of Use

Last updated: July 2026

Here are the terms for this tip calculator, kept plain. Use the site and you accept them; if not, please don't use it.

What it is

A free calculator for tips and splitting a bill. Use it whenever you are working out what to leave and who owes what, at no cost.

Tipping customs vary

The suggested percentages reflect common US restaurant practice. Tipping norms differ by country, by venue and by service, and in many places a service charge is already included. Treat the figures as a guide, not a rule.

Accuracy

The arithmetic is simple and we take care with it, but always glance at your actual bill, especially where tax or a service charge is already on it, before you pay.

Fair use

Everyday use has no limits. Please don't hammer the site with bots, copy it in full, overload it, or use it unlawfully, so it stays quick for the next diner.

Ownership

The design, the code and the copy are ours. The plain maths, that 18% of $50 is $9, is everyone's to use. Just don't lift the whole site as your own.

Links

We link to references. Follow one and you are on another operator's site under its rules, not ours.

Availability and liability

The site comes as it is and as available; features may change or pause without notice. Within what the law permits the site carries no warranties, and we take no liability for losses from using it or from any outage.

Updates

We may adjust these terms; the dated copy on this page is the one that counts.
