How this works

The trip expense splitter treats every shared cost as two things: who paid it upfront and who should ultimately share it. For a simple group trip, each included expense is split evenly between the travellers. Where the group agrees a different arrangement, custom weights can represent different shares, such as one couple taking a larger room or one traveller opting out of an activity.

After every expense is entered, the calculator totals the trip cost, works out each person's fair share, and compares that with what each person has paid. Someone who paid more than their share is owed money; someone who paid less needs to pay in. Rounding is kept to pounds and pence, with any odd penny absorbed by the rounded balances so the group total remains consistent. The optimisation step then nets everything off and suggests fewer repayments than everyone paying everyone else separately.

Assumptions behind this estimate

Assumes all expenses entered are shared by the group unless adjusted with custom weights.
Uses GBP for display but works with any consistent currency.
Does not handle live collaboration or bank transfers.

Worked examples

Four-person weekend trip

Four friends spend GBP640 in total: Maya pays GBP360 for accommodation, Theo pays GBP120 for fuel, Lena pays GBP100 for groceries and Omar pays GBP60 for parking and taxis.
The equal share is GBP640 divided by 4, so each person should end up paying GBP160.
Maya paid GBP200 more than her share, Theo paid GBP40 less, Lena paid GBP60 less and Omar paid GBP100 less. The optimised settlement is Theo pays Maya GBP40, Lena pays Maya GBP60 and Omar pays Maya GBP100.

Activity skipped by one traveller

Three people share a cottage and fuel equally, but only two go on a GBP90 activity.
The shared costs are split three ways, while the activity is split only between the two people who attended.
That avoids charging the person who skipped the activity, while still balancing the rest of the trip fairly.

Several small payments

One traveller pays GBP18 for breakfast, another pays GBP42 for train snacks, and another pays GBP75 for a taxi.
Rather than settling each receipt separately, the calculator adds every payment to each person's balance.
The final settlement list shows the smallest set of repayments needed to square up the whole trip.

FAQ

How do you split trip expenses between friends?

Add each traveller, enter each shared expense with the person who paid, then split expenses equally or by custom shares. The calculator shows who owes whom at the end.

What if one person paid for most of the holiday?

That person will show as being owed money if their upfront payments are higher than their fair share. Others repay them until everyone has contributed correctly.

Can I split some trip costs differently?

Yes. Use custom shares or include only the people who should pay for that expense, such as an activity, room upgrade or private taxi.

Why are settlement suggestions different from the receipts?

The suggestions are netted balances. They are designed to reduce the number of transfers, not recreate every individual receipt.
