What is Tip Calculator?

A tip calculator evaluates gratuity for service personnel based on the bill total and evenly divides obligations among dining guests.

How to Use This Calculator

  1. Enter check amount from receipt.
  2. Select tip percentage.
  3. Specify number of people sharing the check.

The Mathematical Formula & Variables

Tip = Bill * (Tip% / 100); Total = Bill + Tip; Per Person = Total / People

Step-by-Step Worked Example

Scenario: $85.00 bill tipped at 18% split between 2 people.

  1. Tip = $85 * 0.18 = $15.30.
  2. Total = $85 + $15.30 = $100.30.
  3. Per person = $100.30 / 2 = $50.15.

Result: Tip: $15.30 | Each: $50.15
