How the Bill Splitter Works

Splitting the restaurant bill is one of the most common (and sometimes most complicated) tasks of social life. This calculator makes it instant: enter the total, number of people, and optional tip.

The Formula

The calculation is simple:

Per person = Total x (1 + Tip% / 100) / Number of people

Tipping Etiquette

Tipping culture varies enormously across countries:

  • USA: Expected at 15-20%, servers depend on tips for their income
  • Canada: 15-20% is standard
  • UK: 10-15% if "service charge" is not included
  • Japan: Considered offensive, never leave a tip
  • France: "Service compris" is included, extra tip optional
  • Australia: Not expected, 10% for excellent service

Tips for Splitting the Bill Without Awkwardness

  1. Agree beforehand: establish if you are splitting evenly or each paying their own
  2. Use an app: this calculator or apps like Splitwise simplify everything
  3. Round up: avoid calculating to the penny, it is more gracious
  4. Whoever ordered more pays more: if there is a big disparity, it is fair to differentiate
  5. Electronic payment: many restaurants accept multiple card payments

The "Host Pays" Rule

In traditional etiquette, whoever explicitly invites ("Let me take you to dinner") should pay the entire bill. If the outing is mutually agreed ("Want to grab dinner?"), an even split is the accepted social norm.

Frequently Asked Questions

How do you split a restaurant bill?▼
The simplest method is dividing the total by the number of people (even split). Alternatively, you can do a proportional split based on what each person ordered. Among friends, the even split is most common, while in formal settings people tend to pay for their own items.
How much should you tip in the US?▼
In the US, the standard tip is 15-20% of the pre-tax bill. For excellent service, 20-25% is common. For poor service, 10-15% is still expected. At a bar, $1-2 per drink is standard.
Should you tip on the pre-tax or post-tax amount?▼
Traditionally, the tip is calculated on the pre-tax subtotal. However, many people tip on the total including tax for simplicity. Either approach is acceptable -- the difference is usually small.
