Group trips almost never split evenly by accident: one person books the Airbnb upfront, another covers a group dinner, a third pays for the rental car deposit, and by the end of the trip nobody quite remembers who is owed what. Splitting every single expense in the moment is exhausting and usually ends with people just not bothering, which quietly means whoever paid the most upfront effectively lent the group money for free. This tool takes the opposite approach: log who paid for what as the trip goes, then work out the fair net position for everyone in one calculation at the end.
The calculation is based on equal-split logic: add up every expense entered, divide by the number of people to get each person's fair share of the total trip cost, then compare that fair share against what each person actually paid. Someone who paid more than their fair share is owed the difference by the group; someone who paid less than their fair share owes the difference. This method settles every debt in the fewest possible transactions in most cases, rather than requiring everyone to individually reimburse everyone else for every expense.
Splitting evenly assumes everyone benefited roughly equally from the group spending, which holds for most shared trip costs like a group dinner, a shared taxi or a jointly booked apartment. It doesn't automatically account for someone who skipped a meal, booked a separate cheaper room, or didn't join a paid activity — for those cases, either exclude that item from the shared pool and settle it privately between the people actually involved, or simply record it under only that person's name as an expense they "paid" and "owe" in full, which nets out to zero effect on the group split.
The most reliable way to use this tool is to add each expense shortly after it happens, while the amount and who paid are still fresh, rather than trying to reconstruct a week of spending from memory and receipts on the last night. A quick habit of opening this page and logging an expense right after paying for something removes the single biggest source of group-trip splitting disputes, which is disagreement over what was actually spent.
Once the calculation shows who is owed money and who owes it, the simplest way to settle is for whoever owes money to pay directly to whoever is owed, using whatever payment method the group already shares. If your trip spans more than one currency, run amounts through the Currency Converter first so every expense is logged in the same currency before splitting, since mixing currencies in one split will produce a meaningless total.
One more tip for smoother group trips: agree on the equal-split principle with your travel companions before the trip starts, not after costs have already piled up. Setting the expectation early avoids the awkward conversation of retroactively explaining why an equal split is the fairest default once everyone's already mentally tallied their own spending.
Not automatically — for a cost that only some people benefited from, either leave it out of this tool and settle it separately between those people, or log it as an expense where the same person is effectively both payer and sole beneficiary.
Log it as two separate expense entries, one per person, each for the amount they individually contributed, so the totals still add up correctly.
Yes, every expense row stays editable — just change the description, amount or payer directly in the fields before recalculating.
