The Tip Calculation Formula

Tip Amount = Bill × Tip Percentage

Amount Per Person = (Bill + Tip) ÷ Number of People

Common Tipping Guidelines (US)

15%: Considered acceptable for average service at a sit-down restaurant
18-20%: Standard for good service, commonly the default suggestion
20%+: For excellent service

Tipping norms vary significantly by country — many places outside the US either don't have a tipping culture or tip much more modestly, so adjust the percentage based on local customs when traveling.

Splitting the Bill Fairly

This calculator splits the total bill evenly among all people, which is simplest for groups that ordered similar amounts. For uneven splits based on individual orders, each person would calculate their own item total plus a proportional share of tax and tip.
