# How to split a bill unevenly when orders differ

Take the one-off cost out first, then split the rest equally. On a $186 dinner where one person's two cocktails cost $24, she pays $24 plus a quarter of the other $162, which is $64.50. The other three pay $40.50 each. The amounts add back to $186.00. Use exact amounts or a by-item split to record it.

Key points:
- Carve out the outlier: a $24 drink is hers alone, and the other $162 is split four ways at $40.50 each, so she pays $64.50.
- Match the method to why the bill is uneven: orders (by item), usage (shares), income (percent) or a one-off (leave someone out).
- Whatever you enter has to add back to the total. EvenOut shows how much is left to assign until it does.
- Methods can be mixed per expense in one group, so an uneven dinner does not change how the rest of the group splits.

## Which method fits which kind of uneven split?

A bill is uneven for one of four reasons, and each has a method that fits it. Find your reason in the table, then use the matching method.

| Why it is uneven | Method | Example |
|---|---|---|
| People ordered different things | By item, or carve out the outlier | A $24 cocktail tab inside a $186 dinner |
| People used different amounts | Shares | A $210 power bill at 3, 2 and 2 shares is $90, $60 and $60 |
| People earn different amounts | Percent | A $250 grocery run at 60/40 is $150 and $100 |
| One person was not part of it | Equal, leaving them out | A $135 gift shared by three of four people is $45 each |

The shares row works because 3 + 2 + 2 is 7 shares and $210 divided by 7 is $30 a share. Each of these methods is explained in full elsewhere, so the rest of this page works through the first row, because it is the one people get stuck on.

## How do you split a dinner when one person ordered more?

Take the extra amount out, give it to the person who had it, and split what is left. Say four people share a $186 dinner, and one of them also had two cocktails that cost $24 in total.

1. **Carve out the outlier.** The cocktails, $24, belong to her alone.
2. **Split the rest.** $186 minus $24 is $162. Divided four ways, that is $40.50 each.
3. **Add her carve-out to her share.** $24 + $40.50 is $64.50.
4. **Check the total.** Three people at $40.50 is $121.50, and $121.50 + $64.50 is $186.00.

She pays $64.50, and the other three pay $40.50. The same trick works for a dessert one person had or a bottle of wine two people shared. The carve-out goes only to the people who had it, and the rest is split equally.

## How do you enter an uneven split in EvenOut?

There are two routes, and both are free.

**Exact amounts.** Choose "Exact amounts" in the "How to split" sheet and type $64.50 for her and $40.50 for each of the others. A status pill reads "All assigned" once the amounts add up. If you type $40.00 for one of the three by mistake, the pill reads "$0.50 left to assign" and the chip on the main page shows "Split · $0.50 left" until you fix it. If you go over, it says "$X over the total".

**By item.** Choose "By item" and add two lines: "Cocktails" at $24 with only her chosen, and "Everything else" at $162 with all four chosen. Each line splits evenly among the people on it, and the lines must add up to the expense total. EvenOut does not show per-person totals while you build the split, so run the sums above first.

To leave someone out of an equal split altogether, tap them in the "Equally" step. That gives the $135 gift shared by three of the four people at $45 each.

Methods can be mixed per expense in one group. A group can keep an equal dinner, a percent rent and a by-item grocery run side by side.

## What if someone leaves before the bill is over?

Split the bill in stages, so the early leaver pays only for the part they were there for. Say five friends run a $240 bar tab. The first round is $100, and one person leaves before the second round, which is $140.

- The first round is shared by all five: $100 divided by 5 is $20 each.
- The second round is shared by the four who stayed: $140 divided by 4 is $35 each.

The person who left pays $20. The other four pay $20 + $35, which is $55 each. Check: $20 + 4 times $55 is $240. In EvenOut this is a By item split with two lines, "First round" at $100 for all five and "Later rounds" at $140 for the four who stayed.

## How do you split unevenly in Splitwise?

Open the add expense form, enter a description and the amount, and tap "equally" in the "Paid by [you] and split [equally]" line. Choose one of the options shown, or tap "More options" to split the expense unequally. As of October 2026, Splitwise lists exact amounts, percentage, shares, adjustment, reimbursement and itemized splits.

## What if the amounts do not add up?

The total is always the test. Add what you entered and compare it with the bill, because a mismatch of even a few cents means someone owes the wrong amount. Common causes are a forgotten person and a tax line that was left off.

Cents can also be the cause. A $162 split four ways is exact at $40.50, but a $100 bill split three ways is $33.33 with a leftover cent. EvenOut shares leftover cents out so a split always adds to the total. For other situations see [how to split a bill by what each person ordered](https://www.evenoutapp.com/guides/split-receipt-by-item), and for splits based on what people earn, see [splitting by percentage](https://www.evenoutapp.com/guides/split-by-percentage). Tax and tip add their own wrinkle, covered in [how to split a bill with tax and tip](https://www.evenoutapp.com/guides/split-bill-with-tax-and-tip).

## What to do next

Decide why the bill is uneven, pick the matching method and check that the amounts add back to the total. If you want to try numbers before you enter them, the [unequal split calculator](https://www.evenoutapp.com/tools/unequal-split-calculator) does the carve-out for you. If the debate is whether to carve out at all, [split evenly or pay for what you ordered](https://www.evenoutapp.com/guides/split-evenly-or-pay-for-what-you-ordered) covers that choice, and the [split by shares calculator](https://www.evenoutapp.com/tools/split-by-shares-calculator) covers uneven use.

## Frequently asked questions

### Should the person with the cocktails also share the food equally?

That is the usual approach. Her $24 is hers alone, and the shared food and tax are divided across everyone, including her, because everyone ate. The carve-out only moves the part that was not shared.

### What if the uneven part is the tax and tip?

Tax and tip are normally in proportion to what each person ordered, so a bigger order carries more of both. Step-by-step arithmetic is in the guide on splitting a bill with tax and tip.

### Is there a way to split unevenly without typing every amount?

Yes. Use a percent split when you know the ratio or shares when the difference is a count such as nights, and EvenOut shows each person's dollar amount as you type. By item suits different dishes, but it does not show per-person totals while you build it, so you type each price and do the sums yourself.

### Does the person who paid have to be the one who ordered more?

No. The payer is whoever put the card down. The split decides each person's share, and the payer is owed everyone else's.
