Calculators

Tip Calculator

Enter the bill and the percentage you want to leave. If you are splitting it, set the number of people and the calculator shows what each person owes — including the rounding most groups end up doing at the table anyway.

Number of people sharing the bill

Round up

Enter the bill amount and a tip percentage to see the total.

Tipping norms vary by country

The preset percentages reflect common practice in the United States. In much of Europe, Australia and Japan a service charge is already included or tipping is not expected at all. Check local custom rather than defaulting to a number.

How to use this tool

  1. Enter the bill amount before the tip.
  2. Choose the currency you want the figures displayed in.
  3. Set the tip percentage, either by typing it or using one of the preset buttons.
  4. If you are splitting the bill, enter how many people are sharing it.
  5. Optionally round the total, or each person's share, up to a whole unit of currency.

Formula and method

Tip and total

tip = bill × (percent ÷ 100)
total = bill + tip

The tip is a straight percentage of the bill. Whether that bill should include tax before the tip is a matter of local custom, not arithmetic.

Splitting the bill

each person = total ÷ number of people

When rounding is switched on, the rounded figure is calculated first and the tip is worked back from it, so the numbers shown always add up to what actually gets paid.

Worked examples

A $84 bill with an 18% tip

  1. Tip: 84 × 0.18 = 15.12
  2. Total: 84 + 15.12 = 99.12

Leave a $15.12 tip, paying $99.12 in total.

A $200 bill, 20% tip, split four ways with each share rounded up

  1. Tip: 200 × 0.20 = 40
  2. Total: 200 + 40 = 240
  3. Each share: 240 ÷ 4 = 60 — already a whole amount

Each person pays $60, of which $10 is the tip.

Notes and limitations

  • The preset percentages follow United States practice. In much of Europe, Australia, New Zealand and Japan a service charge is either included by law or tipping is not customary — in some places it is actively discouraged.
  • Check whether the bill already includes a service charge before adding a tip, particularly for larger groups, where many restaurants add one automatically.
  • Whether to tip on the pre-tax or post-tax amount is a matter of custom. This calculator applies the percentage to whatever figure you enter, so enter the base you want to tip on.
  • Rounding up increases the effective tip percentage. The calculator shows the effective figure so you can see what you actually left.

Frequently asked questions

How much should I tip?

It depends entirely on where you are. In the United States 15–20% is standard for table service. In the United Kingdom 10–12.5% is common and often already added. In Japan tipping is not expected and can cause confusion. There is no universal answer, which is why this tool lets you set the percentage rather than choosing one for you.

How do I calculate a 20% tip quickly in my head?

Move the decimal point one place left to get 10%, then double it. For an $84 bill: 10% is $8.40, so 20% is $16.80.

Should I tip on the total including tax?

Custom varies and neither is wrong. Tipping on the pre-tax amount is slightly more common advice in the US, but many people simply use the final total. Enter whichever figure you want to tip on.

How do I split a bill with a tip between friends?

Add the tip to the bill first, then divide the total by the number of people. Dividing first and adding tips separately gives the same answer but is easier to get wrong.

Is a service charge the same as a tip?

No. A service charge is added by the restaurant and appears on the bill; a tip is discretionary. If a service charge is already there, an additional tip is optional — and worth checking, since policies on who receives a service charge differ.
