Quick answer

Tip = bill × tip percentage / 100. Add it to the bill and divide by the number of people for an equal split. An 18% tip on 50 is 9, making a total of 59; two people each pay 29.50.

An 18% tip on $50 is $9, for a total of $59.

Units, assumptions, and limitations

  • Choose your own pre-tax or after-tax basis; the tool uses exactly the bill amount entered.
  • People must be a positive whole number. The split is equal and excludes separate items or an existing service charge.

Common mistake to avoid

Adding a second tip without checking whether the bill already includes a service charge.

Split a shared bill

Bill amount
50 $
Tip
18 %
Number of people
2

Result: 9

  1. 50 × 18 ÷ 100 = 9 tip
  2. 50 + 9 = 59 total
  3. 59 ÷ 2 = 29.5 per person

The tip is 9, while each person pays 29.50 including their share of the original bill. Do not confuse the tip output with the per-person total.

No extra tip

Bill amount
90 $
Tip
0 %
Number of people
3

Result: 0

  1. 90 × 0 ÷ 100 = 0 tip
  2. 90 + 0 = 90 total
  3. 90 ÷ 3 = 30 per person

A zero tip still allows an equal split of the entered bill. Check whether a service charge is already included before deciding what percentage to add.
