How to split trip expenses with friends the easy way.

Someone books the apartment. Someone else pays for the rental car. Dinners land on whoever's card is closest to the waiter. By day four, nobody has any idea who is up and who is down, and one person is quietly keeping notes in their phone.

Trips are the hardest kind of shared money: lots of transactions, several payers, mixed currencies, and everyone in holiday mode. The good news is that trip splitting only needs four decisions, and you can make all of them before you leave.

Decide the rules before the first payment

Five minutes in the group chat before departure saves an hour of arguing on the last night. Agree on three things:

• What's shared. Accommodation, transport, and group meals are almost always shared. Souvenirs, extra drinks, and solo activities usually aren't.
• Who fronts what. Spreading the big prepayments across two or three people is fairer than one person floating the whole trip.
• When you settle. Once, at the end, is usually right — not per meal.

Track as you go, not at the airport

Reconstructing a week of spending from memory and receipts is the worst part of any trip. The alternative takes five seconds: whoever pays logs the amount and who it covered, right there at the table. If a payment isn't logged inside a minute, it will be argued about later.

Photos of receipts help for anything itemised — a restaurant bill where two people didn't drink, or a supermarket run that was half personal.

Handle uneven participation properly

Not everyone does everything. Two people skip the boat trip, one person arrives a day late, someone doesn't drink. Splitting every line equally feels efficient until someone realises they paid a third of a diving lesson they didn't take.

The rule that keeps friendships intact: split each expense across the people it actually covered, not the whole group by default. A tool that lets you tick who's in on each line makes this painless.

Settle in the fewest possible transfers

At the end of a five-person trip, you'll often have a tangle like: Ana owes Ben $120, Ben owes Chris $95, Chris owes Ana $60. Paid literally, that's three transfers and a lot of pointless money movement. Netted properly, it's usually one or two.

This is the part worth automating. A minimum-transaction settlement takes everyone's balance and works out the smallest set of payments that squares the whole group. It turns the last-night money conversation into a 30-second exercise.

A few things people forget

• Currency. Agree on one settlement currency up front so nobody argues about exchange rates on day six.
• Card fees. If one person's card charged 3% on every foreign transaction, decide whether that's shared or theirs.
• Deposits. Refundable deposits should be logged and then unlogged when they come back, or someone stays "owed" forever.
• The pre-trip spend. Flights booked three months earlier still count.

How Junto handles it

Junto's Track Only mode is built for trips. You create a group, everyone logs what they pay as it happens, and Junto keeps a running tally instead of nagging people for money mid-holiday. At the end, the settlement engine calculates the fewest transfers needed to square everyone up.

The difference from a pure splitting app: your share of the trip doesn't live in a separate universe from the rest of your money. Junto shows the trip alongside your own accounts and upcoming bills, so when the final number lands you can see what it actually does to your month.

Junto launches 1 October. The free plan covers full personal finance and up to 3 groups, so a trip group costs nothing. The waitlist is open now.
