# How to split expenses: five methods, one worked example

Match the method to what differed between people. Split equally when everyone had the same thing, by percent for an agreed ratio, by shares when use is a count, by exact amounts when each price is known, and by item when people had different things. A $480 bill for four is $120 each equally. EvenOut has all five methods on its free plan.

Key points:
- EvenOut has all five methods on its free plan and lets you pick a different one for each expense in the same group, so rent can be by percent and dinner equal.
- EvenOut shares leftover cents out, so splits add to the total exactly, and a status pill shows what is left to assign for exact amounts, percent and by item.
- Equal split of $480 for four people is $120 each. Percent 40/30/20/10 gives $192, $144, $96 and $48 from the same bill.
- Shares turn a count such as nights stayed into money: 7, 5, 3 and 1 nights make 16 shares of $30, so $210, $150, $90 and $30.
- Every method has one check: the amounts, percents or items must add back to the total before you save.

## What is a fair way to split an expense?

A fair split follows whatever differed between people: nothing (equal), an agreed ratio (percent), a count of how much each used (shares), a price each person already knows (exact amounts) or what each person had (by item). Fair is also what the group agrees before the money moves, so choose the method before the bill arrives where you can.

This page runs one bill through all five methods. Say four friends pay $480 for a cabin, and what differed between them changes from one method to the next.

## The same $480, run through all five methods

### Equally: $120 each

Use it when everyone had the same thing. Divide the total by the number of people: $480 divided by 4 is $120 each. As of October 2026, Splitwise starts every expense as an equal split. In EvenOut, "Equally" shows each person's share, for example "$20.00 each · 3 people", and tapping a name leaves that person out.

### Percent: 40, 30, 20 and 10

Use it when the split is a ratio you can say out loud. The formula is total times percent, divided by 100.

- $480 times 40 divided by 100 is **$192**
- $480 times 30 divided by 100 is **$144**
- $480 times 20 divided by 100 is **$96**
- $480 times 10 divided by 100 is **$48**

The four amounts add to $480, and the percents add to 100. If either check fails, fix the percents first.

### Shares: when use is a count

Use it when people used the same thing for different lengths of time or amounts. Say the cabin was booked for a week and the four friends stayed 7, 5, 3 and 1 nights. Count each night as a share.

1. Add the shares: 7 + 5 + 3 + 1 is 16.
2. Divide the total by the shares: $480 divided by 16 is $30 a share.
3. Multiply by each person's shares: **$210, $150, $90 and $30**.

### Exact amounts: when each price is known

Use it when you already know what each person owes, from a price list or a calculation done elsewhere. Say the master bedroom is $175, the second bedroom is $125 and the two bunk beds are $90 each. The amounts are **$175, $125, $90 and $90**, and they must add to $480.

### By item: when people had different things

Use it when one bill holds charges that not everyone shared. Say the same $480 is made of the cabin at $300, groceries at $120 and a boat rental at $60 that only two people took.

- The cabin, $300 across four people, is $75 each.
- The groceries, $120 across four people, is $30 each.
- The boat, $60 across two people, is $30 each for those two.

The two boat riders pay $75 + $30 + $30 = **$135** each. The other two pay $75 + $30 = **$105** each. Check: $135 times 2 plus $105 times 2 is $480.

## Which method fits which situation?

Equal fits one-off bills where people had the same thing, and the other four exist for when they did not. As of October 2026, EvenOut and Splitwise both offer these five methods under slightly different names, and EvenOut's exact, percent and by-item screens show what is left to assign as you type.

| Method | Use it when | EvenOut | Splitwise |
|---|---|---|---|
| Equal | Everyone had or used the same thing | Equally, with "Not in" to leave someone out | Equally |
| Exact amounts | Each person's amount is already known | Exact amounts, with a "$X left to assign" pill | By exact amounts |
| Percent | The split is a ratio the group agreed | Percent, with each person's dollar share under their name | By percentage |
| Shares | Use differs by a count (nights, days, people) | Shares, with each person's dollar share under their name | By shares |
| By item | People had different things on one bill | By item, free, with tax and tip entered as items | Itemized |

## Does who paid change the split?

No. The split decides what each person's share is, and the payer is whoever fronted the money and is owed the rest. Say Maya paid the $480 and the split is 40/30/20/10 with Maya at 40 percent. Her own share is $192, so the other three owe her the remaining $288: $144, $96 and $48. With an equal split, the other three owe her $120 each, $360 in all.

When two people paid parts of one bill, record two expenses, one per payer, and split each the way it was shared. EvenOut takes one payer per expense when you add by hand.

## How do you check that the split adds up?

Each method has one test, and all of them end at the total.

- **Equal:** shares times the number of people equals the total, give or take cents.
- **Percent:** the percents add to 100.
- **Shares:** the share value times the share count equals the total ($30 times 16 is $480).
- **Exact amounts:** the amounts add to the total.
- **By item:** the items, including tax and tip, add to the total.

Cents are the usual snag. $480 split 7 ways is $68.5714, so six people pay $68.57 and one pays $68.58 ($411.42 plus $68.58 is $480.00). EvenOut shares the leftover cents out for you, and [how to split $100 three ways](https://www.evenoutapp.com/guides/split-100-three-ways) walks through the same problem with a smaller number.

## How do you split expenses in EvenOut?

Tap "Add expense", type the amount, and tap the split chip, which starts as "Split equally". The "How to split" sheet offers Equally, Exact amounts, Percent, Shares and By item, each with a worked example. A status pill tells you what is left to assign ("$X left to assign" for exact amounts, "N% left to assign" for percent), and the chip on the main page reads "Split" with the leftover amount until the numbers add up. The method is chosen per expense, so a group's rent can be by percent and its dinners equal.

## What to do next

Pick the method that matches what was different, run the one check for it and save. For uneven bills see [how to split a bill unevenly](https://www.evenoutapp.com/guides/split-bill-unevenly), and for a ratio the page on [splitting by percentage](https://www.evenoutapp.com/guides/split-by-percentage) has more examples. If you are weighing shares, the [split by shares calculator](https://www.evenoutapp.com/tools/split-by-shares-calculator) runs the numbers, and the [formulas for splitting bills](https://www.evenoutapp.com/guides/formula-for-splitting-bills) page puts every method's arithmetic in one place.

## Frequently asked questions

### Can you use different methods in one group?

Yes. In EvenOut the method is chosen per expense, so one group can hold an equal dinner, a by-percent rent and a by-item grocery run. Nothing about the group has to change when you switch.

### What happens when the total does not divide evenly?

In EvenOut the leftover cents are shared out, so the shares always add to the total exactly. For example, $500 split 3 ways is $166.666, so two people pay $166.67 and one pays $166.66.

### Do I need an app to split expenses?

No. Every sum on this page works with a pencil. An app helps when the same group has many expenses over weeks, because it keeps a running balance instead of making you redo the arithmetic.

### How do you leave someone out of one expense?

In EvenOut's equal split, tap the person's name to leave them out and the rest divide the total among themselves. They stay in the group and in the other expenses.
