How do I calculate a tip?

Multiply the bill amount by the tip percentage to find the tip, then add that tip to the bill. For example, a 15% tip on 80 is 12, so the total becomes 92.

How much is a 15% tip?

A 15% tip is 15 out of every 100 of the bill. On a bill of 80, that works out to 12.

How do I split a bill with tip?

Calculate the total after adding the tip, then divide that total by the number of people paying. That gives you the per-person amount including tip.

How it works

Turn the tip percentage into a real total

A tip calculator starts with the bill amount, works out what the tip percentage is worth in money, and then adds that tip to the bill so you can see the full amount to pay.

Formula

total = bill + (tip % × bill)

First calculate the tip amount from the bill and tip percentage, then add that tip to the bill total. If you are splitting the bill, divide the final total by the number of people.

Worked example

1. Start with a bill of 80.
2. Find 15% of 80 to get 12.
3. Add 12 to 80 to get 92.
4. If 2 people split the bill, each pays 46.
