The Complete World Guide to Tipping: Etiquette, Amounts, and How to Calculate

What Is a Tip?

A tip (gratuity) is an amount of money given voluntarily in addition to the base price as a thank-you for service. One folk etymology claims it stands for “To Insure Promptness,” though the true origin is uncertain.

Tipping norms vary dramatically by country. Not tipping in the US marks you as rude. Leaving a tip in Japan may actually offend the server. Before traveling internationally, understanding local tipping culture is a practical necessity.

2. Tipping Norms by Country

Countries Where Tipping Is Expected vs. Countries Where It Is Not

구분
	USA: Restaurants 15–20%, Hotels $2–5/night, Taxis 10–15%	Japan: Tips are often returned; service is considered included in the price
	Canada: Similar to US. 15–20% is standard	South Korea: No tipping culture. Service charge is built into pricing
	UK: Restaurants 10–15%. Check whether a 'service charge' is already added	China: No tipping except at some international luxury hotels
	Mexico: 10–15%. Expected at tourist areas	Singapore: 10% service charge + GST is added automatically — no additional tip needed
	Egypt, Turkey: $1–5 for guides, hotel staff is appreciated	Australia, New Zealand: No expectation. Occasionally 5–10% for exceptional service

3. How to Calculate a Tip in the US

Basic Formula

Tip Amount = Bill Total × Tip Percentage
Final Total = Bill Total + Tip Amount

Example: $85 bill, 18% tip

Tip: $85 × 0.18 =$ 15.30
Total: $85 +$ 15.30 = $100.30

Quick Mental Math Methods

Method	Approximate Tip	Calculation
Double the tax	~15–18%	Multiply your local sales tax line by 2
Divide total by 5	20%	Bill ÷ 5
10% + half	15%	(Bill × 10%) + half of that

Many US restaurants now print suggested tip amounts at 15%, 18%, and 20% at the bottom of the check. However, if the receipt already shows a “Service Charge” or “Gratuity” line, an additional tip is unnecessary and unexpected. Large groups (usually 6 or more) frequently have an 18–20% gratuity added automatically — always check before writing in a tip.

4. Situation-by-Situation US Tipping Guide

Situation	Suggested Tip	Notes
Sit-down restaurant	15–20%	Even poor service warrants 10%
Coffee shop (counter order)	$0–$ 2	Not obligatory; discretionary
Bar / bartender	$1–2 per drink, or 15–20% on a tab	Adjust upward for cocktails
Hotel housekeeping	$2–5 per night	Leave daily, not just at checkout
Hotel doorman / bellhop	$1–5	More for extra luggage or assistance
Taxi / Uber / Lyft	10–20%	In-app selection is the norm
Hair salon	15–20%	Consider an extra $5 for assistants
Pizza delivery	$3–5 or 15–20%	Tip more in bad weather or for long distances

5. The Tipping Debate

Tipping is increasingly controversial, even in the US.

Arguments for tipping:

Motivates servers to provide attentive service
Allows customers to reward quality directly
Can supplement wages for service workers who value flexibility

Arguments against tipping:

Income instability — workers depend on tips instead of a reliable wage
Research shows tips correlate with server appearance and perceived race, not service quality
Tip inflation: kiosks at fast-food counters and coffee shops now request tips, fueling tip fatigue
A growing number of restaurants are switching to a no-tipping model with higher base prices (a movement pioneered by Danny Meyer and others)

Since 2023, US consumers have pushed back against the rapid expansion of tip prompts to virtually every payment terminal. Surveys show significant “tip fatigue” — especially frustration at being asked to tip for counter-service transactions where traditionally no tip was expected. Some economists argue the shift reflects systemic wage issues that tipping alone cannot solve.
