# How to split $100 three ways (and the extra cent)

$100 split three ways is $33.33, $33.33 and $33.34. Three shares of $33.33 add to only $99.99, so one cent is left over and one person pays it. Work in cents: 10,000 divided by 3 is 3,333 with 1 left over, and the leftover is how many people pay a cent extra. The same method works for any total and any group.

Key points:
- $100 divided by 3 is $33.33 with one cent left over, so two people pay $33.33 and one pays $33.34.
- Turn the total into cents and divide. The remainder is the number of people who pay one cent more.
- $100 among 7 is four people at $14.29 and three at $14.28. $50 among 6 is two at $8.34 and four at $8.33.
- Add the shares to check. If they miss the total by a cent, one share is wrong.

## How do you split $100 three ways?

Two people pay $33.33 and one pays $33.34. $100 divided by 3 is 33.333 and on forever, and nobody can pay a third of a cent. Three shares of $33.33 add to $99.99, so one cent is missing, and one person covers it.

Everyone else can stop reading there. The rest of this page is for totals that do not divide so neatly, and for settling who pays the odd cent.

## How does the cents method work?

Turn the total into cents, divide, and keep the remainder.

1. **Convert to cents.** $100.00 is 10,000 cents.
2. **Divide by the number of people.** 10,000 divided by 3 is 3,333 with 1 left over.
3. **Give everyone the whole part.** Each person pays 3,333 cents, which is $33.33.
4. **Hand out the remainder.** The 1 leftover cent goes to one person, who pays 3,334 cents, or $33.34.

The remainder is the number of people who pay one cent extra. A remainder of 1 means one person. A remainder of 4 means four people. That holds for any total and any head count.

## Which awkward totals come up most?

A total divides evenly only when the head count divides it in cents. These do not:

| Total | People | Base share | Who pays one cent more |
|---|---|---|---|
| $10 | 3 | $3.33 | 1 person, who pays $3.34 |
| $50 | 6 | $8.33 | 2 people, who pay $8.34 |
| $100 | 3 | $33.33 | 1 person, who pays $33.34 |
| $100 | 6 | $16.66 | 4 people, who pay $16.67 |
| $100 | 7 | $14.28 | 4 people, who pay $14.29 |
| $200 | 3 | $66.66 | 2 people, who pay $66.67 |

Take $100 among 7. Four people pay $14.29, which is $57.16, and three pay $14.28, which is $42.84. Together that is $100.00. $100 among 4, 5 and 8 people needs no rounding at all: $25.00, $20.00 and $12.50.

## Who pays the extra cent?

Someone has to, and any of these three rules is fair if you agree it first.

1. **Rotate it.** The person who paid the extra cent last time pays the base share this time. Note it in the group chat if anyone cares.
2. **The payer absorbs it.** Say Ana pays the $100 bill. She takes the $33.34 share, and Ben and Cy each repay $33.33. They send $66.66 in all, and Ana is out of pocket $33.34.
3. **Round everyone up.** Ask Ben and Cy for $33.34 each. Ana receives $66.68, so her bill costs her $33.32, one cent under her base share.

The second rule needs the least bookkeeping, because there is nothing to remember. The third is the one to avoid if the same person always pays, because that person comes out a cent ahead every time.

## How do you check the shares add up?

Add the shares and compare them with the total. Three shares of $33.33 come to $99.99, which is one cent short, so a share is missing a cent. Three shares of $33.33, $33.33 and $33.34 come to $100.00, so the split is sound.

Percentages have the same trap one level up. Three people at 33.33 percent are assigned 99.99 percent of the bill. For percentages, use the [percentage split calculator](https://www.evenoutapp.com/tools/percentage-split-calculator), and see [the formulas for splitting bills](https://www.evenoutapp.com/guides/formula-for-splitting-bills) for each method. If the total includes tax and tip, add them first and then divide, as in [splitting a bill with tax and tip](https://www.evenoutapp.com/guides/split-bill-with-tax-and-tip).

In EvenOut, "Equally" splits to the cent. The odd cents are shared out, never lost, so the shares always add to the total.

## What if the three people should not pay the same?

Move to shares. If Ana had twice the portion of Ben and Cy, give her 2 shares and the others 1 each. That is 4 shares for $100, so one share is $25.00. Ana pays $50.00, and Ben and Cy pay $25.00 each. Four shares go into $100 evenly, so there is no odd cent to place.

## What to do next

Pick a rule for the odd cent before the first bill, so it never turns into a conversation. Then add the total once and let the app do the division.

## Frequently asked questions

### How do you split $200 three ways?

Two people pay $66.67 and one pays $66.66. In cents, 20,000 divided by 3 is 6,666 with 2 left over, so two people pay one cent extra. Check it: $66.67 twice is $133.34, plus $66.66 is $200.00.

### Can you split $100 three ways by percent?

Not with 33.33 percent each, because three of those add to 99.99 percent and one cent of the $100 is not assigned. Give one person 33.34 percent, or use an equal split, which sorts out the cents for you.

### Is it fine to ask everyone for $33 and let the payer cover the rest?

Between friends who do not mind, yes. Three people at $33 cover $99, so the person who paid absorbs $1.00 instead of one cent. If the same person pays every shared bill, those dollars add up, so rotate who absorbs the difference.
