Tip Calculator

Add the tip, split the bill, and settle up without passing a phone around the table.

What this calculator does

It turns a bill and a tip percentage into four numbers you can act on: the tip itself, the total to pay, each person's share of that total, and each person's share of the tip. The split field is optional — leave it blank and you get the single-diner version.

Everything runs inside your browser, so it works on a phone with a weak signal, which is precisely when you tend to need it.

How to use it

  1. Enter the bill total as printed on the receipt.
  2. Enter the tip percentage you want to leave.
  3. Optionally enter how many people are splitting the bill.
  4. Read the total and the per-person figures.

The formulas

Tip amountTip = Bill × (Tip % ÷ 100)
Total to payTotal = Bill + Tip
Each person paysShare = Total ÷ Number of people

Worked example

A 1,450 dinner bill, 15% tip, four people

  1. Tip: 1,450 × 0.15 = 217.50
  2. Total: 1,450 + 217.50 = 1,667.50
  3. Each person: 1,667.50 ÷ 4 = 416.88

Doing it in your head

Find 10% by shifting the decimal point one place left. Half of that is 5%. From those two pieces you can build most common tips: 15% is 10% plus 5%, 20% is 10% doubled, and 12.5% is 10% plus a quarter of it. On a 1,450 bill, 10% is 145, so 15% is 145 + 72.50 = 217.50 — the same figure the calculator produced.

Tipping customs vary widely What counts as a normal tip depends entirely on the country, the venue and whether service is already included. In some places tipping is expected on every bill; in others it is unusual or built into the price. This calculator does the arithmetic; the local convention is yours to judge.

Common mistakes

Tipping on a bill that already includes service. Many restaurants add a service charge automatically. Check the itemised lines before adding a further percentage.

Rounding each share up separately. Four people each rounding up to the nearest note can leave a surprisingly large surplus. Round the total once, then divide.

Splitting evenly when the orders were not. An even split is only fair when everyone ordered similarly. Where they did not, work out each share of the bill first and apply the tip percentage to each.

Frequently asked questions

How much should I tip?
It depends entirely on where you are and what kind of venue it is. This calculator works with whatever percentage you decide is appropriate — it does not assume a local custom.
How do I work out a 15% tip in my head?
Find 10% by moving the decimal point one place left, halve it to get 5%, and add them together. For a 800 bill: 80 plus 40 equals 120.
Should I tip on the pre-tax or post-tax amount?
Both practices exist and neither is universal. Tipping on the pre-tax amount gives a slightly smaller tip; enter whichever figure you have decided to use as the bill.
Can I split a bill between an odd number of people?
Yes, any whole number works. Shares that do not divide evenly are shown to two decimal places, so you can see exactly where the rounding falls.
What if service is already included?
Then the service charge is already in your bill total. Enter 0 as the tip percentage to see the split of what you already owe.
