How to settle up a group trip in the fewest payments

Published October 28, 2026

At the end of a trip, everyone owes a bit to everyone who paid for something, and the group chat fills up with transfers. Work out each person’s balance (what they paid minus their share), then have the people who owe pay the people who are owed. A group of five never needs more than four payments. Below is how, with numbers, and why your money may go to someone you never owed directly.

What is the fewest number of payments to settle a group?

At most one fewer than the number of people: four payments for five people, seven for eight. It can be fewer when someone ends up exactly even, or when a few people inside the group cancel out among themselves.

How do you work out who owes who after a trip?

Stop tracking who paid for what, and look only at each person’s balance.

• Balance = what you paid − your share of everything.
• Positive means you’re owed money; negative means you owe it.
• The balances always add up to zero. If yours don’t, a number is wrong: that’s a 30-second check before anyone sends a cent.

Then match them: the person who owes most pays the person who is owed most, as much as either can take, and you repeat. Each payment clears at least one person, which is why five people never need more than four.

Wait two or three days after the trip before anyone pays. Someone always finds a receipt in a jacket pocket, and it’s easier to add it before the transfers go out than after.

Worked example: five friends, three receipts

Ana, Ben, Carla, Dev and Elena spend a weekend away. Three of them paid for something, and everything is shared equally. The total is €1,050, so each share is €1,050 ÷ 5 = €210.

Receipt by receipt, that’s 12 transfers. Everyone pays back their fifth of each receipt (€90 to Ana, €60 to Ben, €60 to Carla): four people per receipt, three receipts. Netting out each pair still leaves 8. Dev and Elena each pay Ana €90, Ben €60 and Carla €60; Ben and Carla each pay Ana €30 (€90 for the house against €60 she owes them); and Ben’s and Carla’s €60s to each other cancel.

Balance by balance, it’s 4.

To check it: Dev pays €210, and Elena pays €30 + €90 + €90 = €210. Ana receives €210 + €30 = €240, and Ben and Carla receive €90 each. Every balance is now zero. Dev and Elena owe the same amount, so an app may list them the other way round, with Elena paying Ana €210 and Dev the rest. The count stays four.

Why am I paying someone I don’t owe?

Because a debt can pass through a third person. On paper, Dev owes Ben €60 for the car. In the four-payment plan Dev pays only Ana, and all of Ben’s €90 comes from Elena. Ben and Carla pay nobody at all, even though each “owed” Ana €30.

Nobody pays more than their balance and nobody receives more than theirs, so everyone ends up in the same place. The only thing that changes is how many transfers go through the chat.

The exception: if two people would rather settle directly (“I’ll pay Ben for the car myself”), let them. The count goes up by one, and nobody’s total changes.

How many Bizums can I receive?

60 a month, at most €1,000 per Bizum and €2,000 a day received, and banks can set lower limits. Sending has no monthly count limit. The 60-a-month cap is on the Banco de España’s customer site, and Genbeta reported Bizum confirming the 60 and the €2,000 a day still stand.

For a trip, the per-Bizum and daily caps are the ones you hit. Someone who fronted a €1,200 villa can’t be paid back in one Bizum, and someone owed €2,400 can’t receive it all in one day by Bizum. Use a bank transfer for the big ones. Netting helps here too: Ana receives two payments instead of four.

Does Hacienda see Bizums between friends? No. Since 2026, banks report Bizum payments received by the self-employed and businesses, not by private individuals splitting a dinner, as Hacienda clarified in December 2025 (El Independiente, El Español). This isn’t tax advice: if you charge people for something, ask a gestor.

How do I settle up in CabuTally?

The app nets the debts into a short list, never more payments than people minus one, and each person sees only their own lines. Someone who owes one payment sees one line; someone who owes three sees three. Nobody sees the whole table unless the group turns on public balances, which shows who owes whom across the shared expenses.

• Tap an amount to copy it, then paste it into Bizum, Revolut or your bank’s app. The app never moves money itself.
• Whoever receives the money marks the line “received”. The payer can tap “I paid” so the other person knows to check.
• Send your lines to the group chat as plain text, with the direction spelled out on each line. A payment reminder is free on every event.
• Wait for settling, if you like. A co-host or admin can turn on “Wait for settling to record payments”, so nobody records a payment against a total that’s still changing.

If a receipt turns up after people have paid, reopen the event and add it: the new lines cover only what’s left. For closing the books at the end, see wrap up and close the event.

When doesn’t netting help?

When the group can’t agree on the numbers. Four transfers of a wrong total are still wrong. Agree on the expenses before anyone pays: that’s what a wrap-up review is for.

It also doesn’t fit a running balance between flatmates, which never ends and suits an app built for recurring bills: see where Splitwise is still better.
