How to split trip costs with friends without the awkward part

Group trips rarely go wrong over the big costs like the flat. The arguments start over the taxi nobody wrote down, the dinner where one person only had soup, and the forty euros someone has been meaning to mention since Tuesday.

Most of that is avoidable with a few decisions before you leave and a habit while you’re away.

Agree on three things before you go

What’s shared. Accommodation, transport between places and group dinners are almost always shared. Souvenirs and the second cocktail usually aren’t. Say it out loud before the trip so nobody has to argue about it during.

How uneven costs work. Someone doesn’t drink, someone is vegetarian, someone skips the museum. Decide now that people only pay for what they took part in. It costs a few extra taps when you add an expense and saves the conversation later.

When you’ll settle. Pick the last evening or the day after. Settling months later means reconstructing receipts nobody kept.

Kitty or pay as you go

A kitty, where everyone puts in the same cash and spends from it, works well for small daily costs: coffee, snacks, a round of drinks. It falls apart for bigger costs, because someone has to hold everyone’s money and keep topping it up.

For anything bigger than a coffee, it’s easier to let whoever’s card is closest pay, and record it straight away.

Record costs as they happen

The habit that makes the biggest difference is adding each cost when it’s paid, from the phone of the person who paid. Costs left for the end of the day are the ones that go missing, like that taxi.

In split-cash, one person makes a group for the trip and sends the invite link to the group chat. Everyone can then add what they pay from their own phone, and the balances update for all of you. Friends who haven’t signed up yet can be added by name, and their costs are waiting when they join.

Costs that aren’t even

Three common cases, and how to handle them:

• Someone wasn’t there. Untick them on that expense. The cost is split between the people who were.
• Someone had more. Use shares. If Ana had the wine and Ben and Caro didn’t, give Ana two shares of the dinner and the others one each.
• Someone paid for their own part. Record only the shared part, or split it by exact amounts.

Each of these takes a few seconds when you add the expense, and a long conversation if you try to sort it out at the end.

Two currencies

Each split-cash group has one currency, and it never converts amounts behind your back. If most of the trip is in euros and one day is in pounds, convert those few costs yourself when you add them, using the rate your bank charged. If the trip is evenly split between two currencies, keep one group per currency and settle each separately.

Settle on the last day

Here’s what settling looks like for four friends after a weekend in Lisbon. Ana paid 240.00 for the flat, Ben paid 80.00 for dinner and Caro paid 40.00 for the taxi. Everything was split four ways, so each person’s share is 90.00.

Paying back each cost separately would take nine transfers. split-cash nets everything out instead: Ana is owed 150.00, and the others owe her. So it suggests three transfers, all to Ana. Dan sends 90.00, Caro sends 50.00 and Ben sends 10.00. Each person ends up paying exactly 90.00.

Make the transfers the way you usually pay each other, and mark each one as paid. When the balances reach zero, the trip is done.

Questions people ask

Should we use a shared kitty or pay as we go? A kitty works for small daily costs like coffee and snacks. For bigger things, paying as you go and recording each cost is easier, because nobody has to hold everyone’s cash or top it up.

How do you split costs when someone doesn’t drink or leaves early? Leave them out of the costs that weren’t theirs. In split-cash you untick them on that expense, or give the person who had more a bigger share.

How do you split costs in two currencies? Each split-cash group has one currency. For a trip across two currencies, either convert the odd cost yourself when you add it, or keep one group per currency and settle each separately.

When should you settle up after a trip? On the last day or the day after, while everyone still remembers the costs. split-cash suggests the fewest transfers, so settling a whole trip usually takes two or three payments.
