Costs split evenly between the people sharing them; odd cents go to the first names on the list, so it always adds up exactly. For planning only, not financial advice.
No names ticked means everyone shares it. Tick names to split between only them. Your trip stays on this device.
How it works
Fair shares, even when plans differ
Not everyone does everything on a group trip. The splitter handles that with one rule:
- Nobody ticked: the cost is shared by everyone on the trip
- Some names ticked: only those people share it
- Settle up: whoever owes the most pays whoever is owed the most, until everyone is square
In the example, the boat tour is split between the three who went and dinner between two, so Alex pays nothing toward the boat.

FAQ
Good to know
How do I split costs when not everyone joins in?
Tick the names of the people who share that expense. If nobody is ticked, it's split between everyone on the trip. So the house can be shared by all four of you while the boat tour is split between only the three who went.
How is each person's balance worked out?
Paid is everything that person put on their card. Fair share is their part of every expense they share in: the amount divided evenly between the people sharing it. Balance = paid − fair share. A negative balance means they owe money; a positive one means they get money back. All balances always add up to zero.
How does 'who pays whom' keep payments to a minimum?
It matches the person who owes the most with the person who's owed the most, settles the smaller of the two amounts, and repeats. That way a group of 4 never needs more than 3 payments, and usually everyone owes one person.
What happens with odd cents?
Everything is worked out in whole cents. If $100 is split three ways, shares are $33.34, $33.33 and $33.33, with the extra cent going to whoever is first on the people list. That keeps the totals and the payments exact to the cent.
What do the colors mean?
In the balance column, a pink 'Owes' pill means that person needs to pay money in, a green 'Gets back' pill means they're owed money, and a gray 'All square' pill means they're even. Next to each expense, a gray 'Everyone' chip means it's split between the whole group and a pink 'Only 2 of 4' chip means just the ticked people share it. A pink 'Pick who paid' note appears when an expense has no payer (for example after you remove a person), and that expense is left out until you choose one.
