How to split a group trip without a row about money

The fair version of “we will settle up later” is a list, not a feeling. Write down who paid, what it was for, and who should share it. This group trip cost splitter does the arithmetic: it totals what each person paid, subtracts their share, and then tells you who should pay whom so everyone ends up even. Inputs stay in your browser; nothing is uploaded.

Start with the names of the people on the trip — not “the couple” as one unit unless they really do share one wallet. If two people pay from different cards, they need two names, or you will never know who is owed the last train ticket. You can add or remove people at any time. If you remove someone, they are taken out of future splits and you should also remove or reassign expenses they paid.

Equal shares, and the exceptions

Most group costs should be split equally: the apartment, the hire car, a city pass you all use. The important exceptions are meals that only some of you ate, optional activities, and anything one person chose as a gift or a personal extra. For those, uncheck the names who should not share the line. The amount is then divided only among the people who remain.

The person who paid does not have to be in the split. That covers the case where you put a friend’s museum ticket on your card, or you bought groceries for the apartment and will be paid back in full. The calculator still credits you with the payment and assigns the share to the people you ticked.

Rounding and settlement

Amounts that do not divide cleanly — a €10 pizza among three people — are handled in cents. Two people get €3.33 and one gets €3.34, so the shares add up to €10.00 exactly. The leftover cent goes to the first names in the split list. That is ordinary rounding, not a judgment about who ate more pizza.

Settlement is the last step. Instead of paying back every receipt, the tool nets all of the balances and matches debtors with creditors, largest first. If one person is owed €80 and the other two each owe €40, you will see two payments, not a loop of smaller IOUs. Pay those amounts (and note them) and the group is settled.

If you would rather keep the list in a spreadsheet you can share with the group — with bookings, cancelled rows left out of totals, and a running budget in five currencies — move the same names into the Kotlets Travel Planner (opens in a new tab). The Group Split tab uses the travellers from Trip Overview so you do not type the names twice.

Frequently asked questions

How do you split a group trip fairly?

Add up what each person paid, then give each person an equal share of the expenses they actually took part in. The difference is the balance: a positive balance means they are owed money, a negative balance means they owe. This splitter then settles those balances with as few payments as possible.

What if someone paid for a dinner that only two people ate?

Uncheck the people who should not share that expense. The amount is divided only among the names that remain. The person who paid can be in the split, or not — for example if they paid for two friends and were not eating themselves.

How do you settle who owes whom without extra transfers?

The tool nets everything first, then matches the people who owe with the people who are owed, largest balances first. In a typical three-person trip you get one or two payments, not a web of IOUs for every receipt.

Should we split as we go or at the end of the trip?

Either works. Logging receipts as you go is easier than reconstructing a week from memory. You can still make one settlement on the last morning, or when you are home and the last card payment has landed.

Does the splitter handle different currencies?

Enter every amount in one currency. If a lunch was in zloty and the apartment was in euros, convert the lunch first. The Travel Planner (opens in a new tab) can store each expense in its own currency and convert with rates you type in.
