How to Split a Bill by Items: a Step-by-Step Guide

Splitting a large bill exactly by items sounds tedious, but it's five clear steps. Do it once by hand to understand it, then let an app do it in a few taps forever after.

The five steps

1. List the individual items and who ordered each. Your steak, her salad, his two beers.
2. Sum each person's own items. That's their base amount.
3. Split shared dishes equally. Appetizers "for the table," a carafe of water, dessert to share — divide across everyone and add to each base.
4. Distribute the service charge and tip proportionally to each person's running share, not equally — see the service-charge guide.
5. One person pays, the rest transfer their share. Faster for the waiter, no queue at the terminal.

A worked example

Bill of 6000: Anna's items 1500, Boris's 2500, Vera's 1000, plus a shared appetizer of 1000. The appetizer splits three ways (≈333 each), so bases become Anna 1833, Boris 2833, Vera 1333. Add a 10% service charge to each proportionally and you have exact, defensible numbers — nobody subsidizes the person who ordered the ribeye and two beers.

Why not just split equally?

Because of the "eater's dilemma": when the bill is split equally, people order more, and modest eaters lose out — the research is here. Splitting by items removes the incentive and the resentment.

Let the app do it

In DeliBabki, add each item to whoever ordered it, mark shared dishes as split-equally, and the app nets everything into one transfer per person. No mental math at the table.
