How to split a restaurant bill by item, not by head
How to split a restaurant bill by item so the person who had a salad is not paying for the steak - by hand, and with a receipt scanner that reads it.
Learning to split a restaurant bill by item rather than by head is the difference between a fair evening and a quietly annoying one. Divide by six and the person who had a salad and tap water pays for someone else's steak and two cocktails. Everyone notices. Almost nobody says anything. And on a group trip it happens every single night.
This is how to do it properly - by hand when you have to, and with a receipt scanner when you do not.
When splitting evenly is fine
Being honest about this first, because item-by-item is not always worth it. Split evenly when everyone ordered roughly the same amount, the total is small enough that the difference is a couple of euros, or the group has an explicit "it evens out over the trip" agreement and actually means it.
Split by item when someone ordered significantly more or less, someone is not drinking, someone is on a much tighter budget than the rest of the group, or the bill is large enough that a proportional difference is real money. On a two-week trip the "it evens out" theory is usually false, and it is always false in the same direction: it evens out in favour of whoever orders the most.
How to split a restaurant bill by item, by hand
Four steps, in this order. The order matters.
1. Assign every line to a person
Go down the receipt. Each line goes to whoever ordered it. Do this before anyone starts calculating anything, and do it while people can still remember what they ate.
2. Split the shared lines between the people who shared them
The bottle of wine, the bread, the two starters that went in the middle. Split each one between the people who actually had it, not across the whole table. If three of five people shared the wine, it is a three-way split on that line.
3. Total each person's items
You now have a subtotal per person. These should add up to the bill's subtotal.
4. Divide tax and service proportionally, not equally
This is the step people get wrong. If service is 12%, it is 12% of each person's subtotal - not the service charge divided by the number of people. The same for tax. Splitting the service charge equally quietly re-introduces exactly the unfairness you just did the work to remove.
In practice: each person pays their subtotal multiplied by (bill total ÷ bill subtotal). One multiplication each, and it handles tax, service and any rounding at once.
The faster way: scan the receipt
All of the above takes about four minutes and nobody wants to do it at the table. A receipt scanner does the tedious half: photograph the bill, it reads the lines out into a list, and you tap the people who ordered each thing. Tax and service are apportioned for you.
In Deline that is built into the trip rather than sitting in a separate app - photograph the receipt, tap who ordered what, mark the shared plates, and the split lands on the dinner it belongs to on the timeline. It is in the free tier at 5 scans per trip, with higher limits on premium.
Other apps do it too. Splitwise has receipt scanning behind Splitwise Pro, and there are single-purpose scanners that do only this. The alternatives post covers who has what.
Things that make it go wrong
- Waiting until you get back. The receipt is in a pocket, the memory is gone, and now it is a guess. Do it at the table or in the first ten minutes after.
- One person paying and saying "sort it later". Later never has better information than now.
- Rounding in the wrong direction repeatedly. Rounding to the nearest euro is fine once. Across thirty meals it is not, because everyone rounds in their own favour without noticing.
- Forgetting the tip. Agree whether the tip is proportional or a flat split before it is added, not after.
The etiquette bit
Splitting by item has a reputation for being fussy, and it is worth handling that directly. It is only fussy if you make it a performance. Do the assigning quietly on a phone while the coffee arrives, and nobody at the table experiences it as anything at all.
What is genuinely rude is the opposite: insisting on an even split when you ordered the most. Whoever ordered the expensive thing should be the one suggesting the itemised split, not the person who had soup.
And once the split exists, it should not need chasing. On a trip, it goes into the running total and gets settled at the end with everything else - in as few payments as possible.
Questions people ask
How do you split a restaurant bill by item?
Assign each line on the receipt to whoever ordered it, split shared dishes between only the people who shared them, total each person’s items, then add tax and service in proportion to each person’s subtotal rather than dividing them equally.
Should tax and tip be split equally or proportionally?
Proportionally. Tax and service are percentages of what was ordered, so splitting them equally reintroduces the unfairness that itemising removes. Multiply each person’s subtotal by the bill total divided by the bill subtotal.
What is the best app to split a restaurant bill by item?
Any app with receipt scanning saves the most time, because the itemising is the slow part. Deline includes receipt scanning free at five scans per trip and attaches the split to the meal on your trip timeline; Splitwise offers scanning on its Pro tier.
How do you split shared plates fairly?
Split each shared line only between the people who actually ate it. A bottle of wine shared by three people out of five is a three-way split on that line, not a five-way one.
Is it rude to ask to split the bill by item?
No, particularly if you are the one who ordered more. It becomes awkward only when it is made into a performance at the table. Sort it quietly on a phone while coffee arrives and nobody experiences it as anything.
