How the Calculation Works

Multiplies bill by tip rate and splits total equally.

Formula: Total = Bill × (1 + Tip%) | Per Person = Total / Diners

Practical Worked Example

Given Inputs: 85 Bill | 18% Tip | 2 People

Calculated Output: 50.15 per person (15.30 tip total)

  1. 85 + 15.30 = 100.30 total / 2 = 50.15.
Pro Tip: Check if the bill already includes a service charge before calculating your tip to avoid tipping twice.
