A complete playbook for handling money on a group holiday - what to agree before you go, how to track spending without spreadsheets, and how to settle up cleanly when you get home.
You and three friends are renting a place in Lisbon for a week. One of you books the flights. Another pays the deposit on the apartment. A third buys the groceries on day one and the wine every night. By day five, nobody can remember who paid for what, and the conversation about squaring up gets quietly postponed until you're home, by which point half of you have lost the receipts.
That's the shape of every group holiday money problem. Below is what we'd agree before the trip, what we'd track during it, and how we'd settle when it's done.
Pick a default split (usually equal), pick a tracker (a shared list, not memory), and settle in one transfer per person at the end using the smallest set of payments. Everything else is detail.
Almost every group holiday should default to equal split, across everything that benefits everyone. The Airbnb. The rental car. The shared groceries. The taxi from the airport. If most expenses are split equally, exceptions are easy to flag.
The exceptions are usually:
Someone has to put their card down for the apartment, and often a second person for the flights. Two rules that cut a lot of awkward later:
WhatsApp threads are not a tracker. Memory is not a tracker. A shared Google Doc that one person updates on day three is not a tracker.
A tracker is something every person in the group can add to in three seconds, that runs balances automatically. That's what an app like EvenRound is for. Open the group, hand the link around, every member adds their own expenses as they happen. No "I'll add it later". Later doesn't exist.
Add an expense within 30 seconds of paying for it. Use the receipt scanner if there's a paper receipt; just type if there isn't. Most expenses don't need a category, a note, or any thought at all. Description, amount, paid by, split equally, done.
Why 30 seconds? Because the alternative is an end-of-day "reconciling" ritual that one person has to do alone. Nobody wants to be that person.
On most trips, somebody hits an ATM, takes out €200, then pays cash for small things while the rest of the group taps cards. That's fine, but two pitfalls:
If you're abroad, set the group's default currency to the local one. EvenRound auto-detects from your country, but you can change it on the new-group form. Each person enters expenses in whatever currency they actually paid in - the app handles conversion at mid-market rates.
We have a whole explainer on mid-market rates without the jargon if you want to understand why the rate your bank gives you is worse than the one we use.
You went out for dinner. Some people had three courses, two had a main only. The bill comes back at €240 for six people. Equal split would make the salad-eaters subsidise the wine-pairers by €15 each.
Two options:
Our default rule: itemise dinners over £100 total. Equal-split anything below that. If you're itemising, the receipt scanner makes it nearly automatic.
Almost every group has one person who's being more careful. Maybe they just bought a flat. Maybe they're between jobs. Two things the rest of the group can do:
Money etiquette in friend groups is its own topic. We wrote a longer piece on the one conversation that fixes friend-group money if this is a recurring pattern with your crew.
On a week-long trip, somebody might get food poisoning and skip two days of activities, or have to fly home early. Default rule: the accommodation is still split equally (the room was held; the bed was kept). Activities they didn't attend aren't. Meals they weren't at aren't.
The right way to do this in a tracker: when you log an activity or meal, deselect the people who weren't there from that specific expense. Don't try to "fix it" at the end with manual adjustments.
At the end of the trip, the app should compute the smallest set of transfers that settles all balances. For four people, that's usually two or three transfers - not twelve. We wrote up the algorithm in detail in the greedy debt-minimisation algorithm, explained for non-coders.
The "Settle up" screen will tell each person exactly who to pay and how much. They tap a button, choose Wise / Revolut / PayPal, the app pre-fills the amount, and they're done. Nobody has to do mental arithmetic.
The single biggest reason group money goes weird isn't maths - it's delay. Settle within 48 hours of getting home. Two weeks later, the receipts are vague, the goodwill has faded, and someone starts a passive-aggressive WhatsApp message.
We send everyone a one-tap "Settle up" link within the app. Take the ten minutes on the train home from the airport.
After running this on a dozen group trips ourselves, the only thing we actively changed was settling more frequently on long trips. On a seven-day trip, we now settle on day four as well as day seven. It keeps individual exposure under £200 per person at any given moment, which removes the awkward "you're carrying a lot for everyone" feeling.
Set up a group, share the link in your trip WhatsApp, and have everyone add expenses as they happen. No accounts, no apps to download. If you want to see what it looks like with a real trip's worth of data, try the demo group- it's a worked example of a Lisbon trip with four people, twelve expenses, and a clean settle-up plan.
