Tip Calculator

The Tip Calculator takes a bill amount and the tip percentage you choose, then works out the tip, the total including the tip, and how much each person pays if several people split it. It only multiplies and divides. It does not know the tipping customs where you are, does not break tax out separately, and cannot tell whether your bill already includes a service charge. The percentages commonly used when eating abroad, 10%, 15%, 18% and 20%, are available as one-tap buttons.

How to use it

1. Type the bill into "Bill amount". The default is 500.
2. Under "Tip / service charge (%)", tap 10%, 15%, 18% or 20%. The selected button is highlighted. Or type any percentage in the box below, such as 12.5.
3. Enter the headcount in "Number of people splitting" (default 1). A value of 0, a negative number or an empty box is treated as 1 person; decimals are cut to the whole number, with a red note under the box saying how many people were used.
4. Read "Tip amount", "Total incl. tip" and "Per person" in the result section.
5. If the bill already includes a service charge, set the percentage to 0.

Worked example

These numbers come from running the same formulas as the tool. A bill of 500 with a 15% tip gives a tip of 75.00 and a total of 575.00. One person pays 575.00, and three people splitting it pay 191.67 each. Another case: a bill of 328.5 at 18% split four ways gives a tip of 59.13, a total of 387.63 and 96.91 each. A bill of 100 at 20% split two ways gives a tip of 20.00, a total of 120.00 and 60.00 each.

Supported features and known limits

• One percentage applies to the whole bill. You cannot set different tip rates for different dishes.
• The tip is calculated on the bill amount you enter. If your bill includes tax and local custom is to tip on the pre-tax amount, enter the pre-tax figure yourself.
• The split is always equal. To divide by what each person ordered, calculate each person's share separately or use the Bill Split Calculator.
• The headcount uses the whole-number part and is never less than 1, so you cannot enter 0 people.
• The percentage is clamped to 0-100 (above 100 counts as 100, negatives as 0), a negative bill counts as 0, and an empty percentage is treated as 0.
• The Chinese interface labels amounts in yuan, but the arithmetic does not depend on currency, so you can use any currency.
• Results are rounded to two decimals, so per-person amounts multiplied back by the headcount may differ from the total by a cent or two. For example, 191.67 x 3 = 575.01.

How much should I tip in different countries?

Customs vary widely. In some countries restaurant bills include a service charge by default and nothing more is expected, in some places 15% to 20% is typical, and in others tipping is not a tradition at all. The tool has no country rules built in, so follow local custom and what the bill says.

Is the total just the bill plus the tip?

Yes: total = bill + bill x percentage / 100. The tool does not treat tax separately.

Why is 575 split three ways 191.67 each, when three of those do not add up to 575?

Each amount is shown to two decimals. 575 / 3 is 191.666..., which displays as 191.67, and three of those add up to a cent more. When paying, one person can simply pay a cent less.

Can I calculate the tip on the after-tax amount?

The tool only works from the bill amount you type in. Whether to use the pre-tax or after-tax figure depends on local custom. Enter whichever amount you want the tip based on.

Privacy and how your data is handled

The calculation runs entirely in your browser. The bill amount and other values are not sent to a server or stored. Refreshing the page restores the defaults.
