Bill and tip
  • Bill$84.00
  • Tip$15.12

What this means

  • The tip is $15.12 at 18.0%, so the bill plus tip is $99.12.
  • Split 3 ways, each person pays $33.04.

What if

Tip at 20% Keep the bill and the group, and use a 20% tip. Each person pays $33.60 instead of $33.04.
Tip at 15% Use a 15% tip. Each person pays $32.20.
One more person Split the same total across a larger group. Each person pays $24.78.
Round shares up Round each share up to the next dollar. Each person pays $34.00, and the group pays $102.00.

About this calculator

What this calculator does

It adds a tip to a bill and divides the total by the number of people. An optional round-up sends each share to the next whole dollar.

How it is calculated

Tip is the bill times the tip percent. The total is the bill plus the tip. Each share is the total divided by the number of people:

tip = bill * tip percent / 100

share = (bill + tip) / people

With round up on, each share becomes the next whole dollar. The group may then pay a little more than the exact total. That extra is the difference between the collected amount and the bill plus tip.

How to read the result

The large number is what each person pays. Bill plus tip is the exact check. Collected from the group matches that total unless round up is on.

What is left out

Tax is included only if it is already in the bill you enter. The calculator does not add sales tax, and it does not split items by what each person ordered.

Sources and method

Standard arithmetic with no outside data. The formula is shown under How it is calculated, and unit tests check worked examples, including edge cases.

This page uses arithmetic only, with no outside data.

Questions

Does this add sales tax?

No. Enter the bill you want to split. If tax should be included, add it to the bill first.

What does round up do?

It raises each person's share to the next whole dollar. A share of 33.04 becomes 34. The group total can be higher than the exact check.

Can I use a tip other than 15, 18, or 20?

Yes. Type any percent from 0 to 100. The what-if buttons only preview 15% and 20%.

Why must the people count be a whole number?

The split is per person. A fraction of a person is rejected so the share stays meaningful.

Is the tip calculated before or after a round up?

The tip is calculated from the bill first. Round up happens after the total is divided.
