When to Tip and How Much
The short version: US vs. UK/EU, services beyond restaurants, and split-bill math.
Tip norms vary wildly by country and service — knowing the local default saves awkward math.
Tipping is one of those everyday calculations where the rules differ by country, service, and sometimes by city. The mental-math is easy once you know the expected percentage.

Quick answer
Tip norms vary wildly by country and service — knowing the local default saves awkward math.
Key points
- ▸ US: 18–20% is standard at sit-down restaurants. 15% is low. 10% in some countries is normal.
- ▸ UK / EU: 10–12.5% or a "service charge already added" line — check the bill first.
- ▸ Rideshare (Uber, Lyft): 10–15% in the US; typically none in UK/EU unless you want to round up.
- ▸ Hairdresser, barber, massage: 15–20% in the US; rounding up is common elsewhere.
- ▸ Split bills: calculate tip on the pre-split total, then divide — not the other way around.
Examples
- US restaurant, $80 bill20% tip = $16. Total $96. For 18%, subtract about 10% of the tip ($1.60).
- UK restaurant, £65 billCheck for service charge first. If none, 10% = £6.50 is a normal tip. 12.5% = £8.13.
- Split 4 ways$100 bill, 20% tip = $20, total $120. Divide by 4 = $30 each. Do NOT split first and tip per person — harder math, same answer.

Frequently asked questions
› Do I tip on tax?
Common practice in the US: tip on pre-tax total. But many people tip on the total bill (including tax) because it is easier — the difference is usually a dollar or two.
› What if service was bad?
In the US, 15% is the traditional "I'm signalling unhappy" tip; under 10% is a strong statement. Outside the US, reducing or removing the tip is more acceptable.
› How should I use this guide with a Kefiw tool? How-to
Use the guide as the plan and the linked Kefiw tool as the check. Read the steps first, try the move manually, then use the tool to compare outputs, catch edge cases, and decide whether the result actually fits your task.
› What mistake do tool guides help avoid? Troubleshooting
Tool guides help avoid using a utility mechanically without understanding what you are trying to accomplish. Most word, writing, and text utilities are fast, but speed can hide context mistakes. Know whether you are solving a puzzle, cleaning copy, drafting a line, or checking a rule.
› Can a tool guide help me learn the skill? How-to
A tool guide can help you learn if you pause before accepting the output and ask why it worked. Compare your first guess with the tool result, look for the rule or pattern, and repeat that review. Passive copying solves one task; active review builds the skill.
