Equal vs Item-Based Split (Tax & Tip)

Method How It Works Best For
Equal Split Total bill (including tax & tip) divided equally When everyone ordered similar items
Item-Based Split Each person pays their share + proportional tax & tip When orders are uneven

Real-Life Scenarios: How to Split Tax & Tip

1. When Everyone Orders Different Items

This is the most common situation. Each person should pay for what they ordered plus their share of tax and tip.

Splitting equally in this case is unfair. Instead, calculate based on individual orders to ensure fairness.
