How to split costs on a group trip
One person books the house, another rents the car, and by the last night nobody’s sure who owes what. How to split a trip with friends fairly, and have it settled before you’re home.
Three ways groups split a trip
One person pays for everything, and everyone pays them back. Simple to start, but that person fronts hundreds or thousands of dollars, keeps every receipt, and does the math at the end.
A kitty. Everyone puts the same amount in a pot up front, in cash or to one person. It works for the small things, but it runs out, someone has to top it up, and the house and the flights never fit in it.
Everyone pays as it comes, and it evens out at the end. Whoever’s card is out pays and adds it to a shared list. At the end you add it all up and whoever spent less than their share pays whoever spent more. It’s the fairest of the three, and the one the card above does: Omar fronted the house, Nico sat out the kayaks, and it still comes out right. Change what the house cost and watch who pays whom.
What to keep track of
- Where you stay. The house, the hotel rooms, the campsite. Add the deposit the day it’s paid, months before the trip.
- Getting around. The rental car, gas, parking, tolls, the ride from the airport.
- Food and drink. The big grocery run, dinners out, the round someone bought.
- Things not everyone does. The boat, the tour, the show: split between the people who went.
- What isn’t shared. Flights, souvenirs, anything one person bought for themselves. Leave them out, unless one person paid for others.
Agree on it before you go
- What’s shared and what isn’t. One message in the group chat before anyone books saves an argument on the last night.
- That things are split evenly unless someone wasn’t there for them. Someone who stays fewer nights pays for fewer nights; the Airbnb calculator works it out.
- That you settle once, at the end, not after every meal.
How to do it without a spreadsheet
- Start a potluck for the trip and drop the link in the group chat. Your friends tap it and pick their name: no app to download, no account.
- Everyone adds what they pay as they go, from their own phone, while the receipt’s still in hand.
- At the end, it shows the fewest payments to square everyone up. Pay each other however you like; if you add your Venmo, PayPal or Cash App username, your friends get a link to pay you. Then mark it settled.
Some trips come with their own questions: who covers the groom on a bachelor party, the bride on a bachelorette, and the friend who flew down for spring break. And for the habits that keep money out of the group chat, see splitting a trip without keeping score.
Questions
What’s the fairest way to split costs on a group trip?
Everyone pays for things as they come up and adds them to one shared list, each split between the people it was for. At the end you add it all up and square up in as few payments as possible. Nobody fronts the whole trip, and nobody keeps a spreadsheet.
Should flights be split?
Usually not: everyone books and pays for their own. If one person booked them all, add the flights as one expense, split between the people flying.
What if someone skips an activity or a dinner?
Leave them out of it. Every expense is split only between the people you pick, so the others don’t pay for what they didn’t do.
What if someone stays fewer nights?
Split the place by nights: one share for each night a person stayed. Potluck’s Shares split does this; the ski trip page works an example through.
When should we settle up?
Once, at the end of the trip or within a few days of getting home. Settling after every dinner means far more payments than settling once.
We’re going abroad. What about the currency?
Each potluck has one currency, which you can change in its settings until the first expense is added. Potluck doesn’t convert between currencies yet, so pick the one you’ll spend most in.
Does everyone need to download an app or make an account?
No. They tap the link in the group chat, pick their name, and they’re in, in the browser they already have.
Is it free?
Yes, with no limit on how many expenses you add, so a week of dinners, gas stops and tickets doesn’t hit a cap.
