How to split group expenses fairly

There’s no single fair way to split costs: it depends on the group and the expense. These are the most common methods, when to use each one and how to settle up without fuss.

Equally

The simplest method: the total is divided by the number of people. It works well when everyone benefits equally, such as a trip’s accommodation or a flat’s shared shopping.

Only among those involved

If someone skipped dinner or doesn’t use the car, it makes no sense for them to pay. Split that expense only among those who took part; everything else stays equal.

By consumption or exact amounts

When people had different amounts, as in a restaurant, each person gets their exact amount. What’s shared (the wine, the bread) can be split separately.

Proportionally (by shares)

Useful for couples with different incomes or flats with rooms of different sizes: each person has a number of shares and pays in proportion. With 3 and 2 shares, one pays 60 % and the other 40 %.

How to settle up

In the end each person has a balance: what they paid minus their share. The balances of the whole group always add up to zero.

Example: mixing methods

Four friends on a trip: the flat split equally, an excursion Olivia skipped and fuel split between the two who use the car.

Payments to settle up

Everyone pays only their part, and three payments settle everything.

How it works

  1. Create a group with everyone’s name.
  2. Share the link: anyone who has it can see the group and add expenses.
  3. Add each expense and who paid it. Pa-ga-me works out the balances and the payments to settle up.

Frequently asked questions

Which method is the fairest?

Whichever the group agrees on before starting. Splitting equally is simplest; by consumption or proportionally is more precise when there are big differences.

Do we need to settle after every expense?

No. It’s easier to keep recording and settle at the end or now and then: debts cancel each other out.

What about cents that can’t be divided?

They’re assigned one by one to some people, so the shares always add up to the total.
