How to tip appropriately
Tipping is a social convention rather than a legal obligation, but knowing the right figure makes paying easier. This guide explains how a tip is computed from the bill, how it is split within a group, and gives a worked example matching Klar’s tip calculator.
The tip is a percentage of the bill
A tip is computed as a percentage of the bill and added to it: tip = bill × percentage ÷ 100, and total = bill + tip. There is no mandatory rate; choose the percentage by service quality and local norms (for example 10% is common in many places).
A worked example
Using the calculator’s values: bill 120, tip 10%, for 4 people. The result: tip 12, total 132, and each person pays 33.
Splitting the bill
If you leave the number of people empty, it defaults to one. When splitting, the total (bill + tip) is divided by the number of people — not the bill alone with the tip added after the split.
Common mistakes
Among the mistakes: computing the tip on a discounted price and then adding it to the original bill, working out the per-person share before the tip and adding it again after the split (which doubles it), and assuming changing the currency converts the amount — the currency only formats it.
Key takeaways
- Tip = bill × percentage ÷ 100, and total = bill + tip.
- The number of people defaults to 1 when left empty.
- Per person = total (with tip) ÷ number of people.
- The currency is display-only; there is no conversion between currencies.
Frequently asked questions
Is the split based on the total with tip?
Yes. The total (bill + tip) is divided by the number of people.
Can I tip in a different currency?
No. The currency only sets the display format and performs no conversion.
