What's the difference between equal, exact, share, and percent splits?

Equal divides the total evenly across selected members. Exact lets you type each person's amount. Shares lets you assign weights (e.g., 2 to one person, 1 to others). Percent splits by percentage. Pick whichever matches the situation.

Can I split by item from a restaurant receipt?

Yes. Snap the receipt, our AI extracts line items, and you assign each line to who ordered it. Tax and tip are split proportionally. It's the cleanest way to handle mixed-order restaurant bills.

How is the settlement plan calculated?

We use a greedy debt-minimization algorithm: repeatedly settle the largest debtor against the largest creditor. The result is a payment plan with at most n−1 transfers (where n is the number of members with non-zero balances). It's also called 'simplified debts' in some apps.

How does multi-currency work?

Each group has a default currency. You can record an expense in any currency - at write-time we snapshot the FX rate so balances stay stable even when rates move later.

How are FX rates determined?

We pull daily mid-market rates from the European Central Bank where available, falling back to OpenExchangeRates for currencies the ECB doesn't cover. The rate used is the one published on the date of the expense.

What happens when a member leaves mid-trip?

Their existing shares stay attached to past expenses. They're just excluded from future ones. We don't retroactively rebalance - that'd silently change history.

Why group travel turns into a money problem

Travel is the single most reliable way to make a friendship go quietly weird. Someone books the Airbnb on their card. Someone else covers the rental car deposit. The third person pays for groceries because they happen to be at the supermarket when the others are unpacking. By day three, there are six open tabs in three different apps and nobody remembers who paid for the airport transfer.

The math itself is simple - you owe the person who paid for you, they owe the person who paid for them - but the social layer is where it falls apart. People feel weird asking for €40 back. People feel weirder still typing in "€11.50 for that round of coffees" on day six of a holiday. So expenses go unrecorded, balances drift, and someone ends up silently subsidising the trip.

Multi-currency adds a second layer of confusion. You paid €240 in Lisbon for an apartment, your friend put $90 USD on a dinner in Porto on a card with a 3% FX fee, and a third person paid 12,000 yen for a taxi share weeks later. What rate do you use? Whose bank's? When?

The fix is not a spreadsheet. It is a system that captures every expense in five seconds, holds the FX rate at the moment of the expense, and at the end of the trip tells every person exactly one number: who they owe, and how much. That is what this guide is about.

The ideal split mode for trips

Most trip expenses split evenly. Hotel room, rental car, shared groceries, gas: divide by the number of people, move on. Equal split is the right default and you should resist the urge to overthink it.

Equal stops being right when one person genuinely did not use a thing. The classic case is splitting a bar tab when one person doesn't drink: if four of you spent €120 on wine and one person had sparkling water, equal-splitting punishes the non-drinker for being polite. Use Exact mode and assign €0 to that person. Same logic for activities - if two of you went parasailing and four of you went to the beach, the parasailing line item belongs to the two, not the six.

Shares mode is for the bedroom-size problem. If one couple is in the master suite and the others are in twin singles, splitting the rent equally feels off, but splitting it exactly is awkward to negotiate. Shares lets you say "the master pays 2, every other room pays 1" and the math falls out cleanly. Same trick works for car-rental fuel where one driver did most of the long highway legs.

The default rule of thumb: Equal for nights and shared logistics, Exact for restaurants and activities, Shares for sleeping arrangements.Mixing modes per expense is fine - it's actually a sign you're being honest about what got used.

Multi-currency: pay local, settle home

When a group has a default currency (say, EUR) but expenses occur in different currencies, every expense should be recorded in the currency it was actually paid in. That preserves the fact: you spent ¥12,000 on a taxi in Tokyo, not "about €75". The €-equivalent only matters at settlement time.

The catch is FX. The mid-market rate (the one Google shows) is not what your bank gave you. Most cards apply a 1-3% spread, sometimes worse. Snapshotting an FX rate at the time the expense is logged is the only way to keep the group's math stable - if you re-fetch the rate at settlement, balances will drift every day for reasons unrelated to the trip.

We dive deeper on the trade-offs in splitting expenses across multiple currencies and the difference between bank rate and market rate. The short version: snapshot the market rate at write time, accept the small drift versus the actual bank receipt, and call it close enough. The alternative - every member adjusting their card statement against the group ledger - is a recipe for nobody ever settling up.

City-specific guides

Every destination has its own quirks: tipping etiquette, card vs cash density, expensive transit, surprise tourist taxes. We've written a per-city guide for the 25 destinations groups ask about most often, each with a budget breakdown, three real-world scenarios, and a recommended split mode.

Common scenarios

A few patterns come up over and over. Each has its own answer and its own walkthrough.

Roommates extending into a trip.Your flatmates decide to do a weekend in Berlin together. The rent group continues, but the trip is a different cost pool. Don't mix them - create a second group so the monthly recurring expenses don't pollute trip balances. See the group trip abroad use case.

Weddings abroad.One person paid the villa, the bride's side covered catering, the groom's side covered transport. Track contributions early so the post-wedding settlement isn't a spreadsheet. Tagging expenses by category makes the final summary easier.

Long international trip with a side group.Five of you fly out together; two stay an extra week. Don't retroactively split the extra-week expenses across all five. Use a separate group for the extension.

Mixed group sizes per activity.Three surfed, four hiked, one stayed at the hostel. Each activity is its own line item with its own participant list. Don't average it out.

Settle up: the math that minimizes transfers

At the end of a trip with seven people, the naive answer is everyone pays everyone else: up to 7 × 6 = 42 potential transfers. Almost none of those are needed.

A greedy debt-minimization algorithm sorts members into "owes" and "is owed", then matches the largest debtor with the largest creditor and resolves them in one transfer (the smaller of the two amounts). Repeat until everyone is at zero. For a group of 7 the answer is almost always 4 to 6 transfers, never 42.

Worked example: A is owed €120, B is owed €40, C owes €70, D owes €90. The algorithm sends D → A for €90 (D is now zero, A is owed €30 still), then C → A for €30 (A zero, C owes €40 still), then C → B for €40 (both zero). Three transfers settle the whole group. We unpack the algorithm in detail in smart settlement: the math that saves you transfers.

What can go wrong (and how to fix it)

Someone drops out mid-trip

Their existing shares stay attached to past expenses. They're excluded from future ones. Don't retroactively rebalance - that silently rewrites history. Walk through it in how to deal with a dropout mid-trip.

The split feels uneven

Almost always a mismatch between the split mode and the situation. The fix is per-expense, not per-trip - see how to handle an uneven split gracefully.

Someone forgot to log expenses

Three days later, the receipts surface. Add them with their original date - the order they're entered doesn't matter, the date they occurred does. More in how to handle late expenses.

One person isn't paying back

Tools we recommend (yes, including others)

We make EvenRound. We also know it's not the only option, and pretending otherwise insults your judgment. Here's the honest read.

EvenRoundis built around the no-signup, magic-link model. You create a group, share a link, and people are in. Multi-currency is first-class. AI receipt scanning splits restaurant bills by item. Free forever. The trade-off: no app store presence and no "all my groups across years" profile, because there's no account to attach them to.

Splitwiseis the incumbent. Its strength is the long-running tab between roommates and friends - it's fine for that. The trade-off is the freemium model that gates basic features (currency conversion, multiple expenses per day on free) behind a subscription. See our full EvenRound vs Splitwise comparison.

Tricount is the European favourite for travel specifically. No-signup, clean, fast. It does what it does well. We compare side-by-side in EvenRound vs Tricount. If you've already adopted Tricount and your group is happy, switching for the sake of switching makes no sense.
