Tip Calculator for Restaurants and Group Dinners

By Express Services Group Editorial TeamPublished May 8, 2026Reviewed September 2026

Math at a restaurant is harder than it should be: 4 people, one tipsy person paying with a different card, a service-charge surprise. The Tip Calculator handles the percentages; this guide handles the etiquette.

Step-by-step

  1. 1

    Tip on pre-tax or post-tax?

    Pre-tax is the original "20% of the meal" convention. Post-tax adds maybe $1-2 more on a typical bill. Either is acceptable; consistency matters more.

  2. 2

    Standard percentages

    15% poor service, 18% adequate, 20% good, 22-25% great. Below 15% sends a message you may not intend; above 25% is generous, not required.

  3. 3

    Split evenly with the calculator

    Enter the bill, tip percentage, and number of people. The Tip Calculator returns per-person total — easiest when everyone shared similar dishes.

  4. 4

    Itemize when ordering varies wildly

    If one person had soup and one had steak + cocktails, even split feels unfair. Use a separate split-by-item app, or have each person pay their items + their share of tax/tip.

  5. 5

    Watch for already-included service charge

    Many restaurants auto-add 18-20% gratuity for parties of 6+. Read the bill — adding tip on top is double-tipping.

FAQ

Do I tip on the alcohol portion?

Yes. Bartenders and servers split tip pools, and pouring a $14 cocktail is real work.

What about international tipping?

Varies wildly. Japan: no tip ever (insulting). Europe: 5-10% if not included. Australia: optional. Stick to local norms; US 20% defaults can offend.

Tip on delivery?

10-15% or $3-5 minimum. Drivers bear gas, vehicle wear, and weather. Bad tippers get bad service over time.
