You pay $300 for the hotel

Your balance: +$110
(Gie) my balance: -$40

Ava owes you $70

How do I manually calculate shared expenses?

If you want to calculate split expenses manually here is how to do it:

1. Make a list of your group

First write down everyone that is part of the group.

They can be the people you travel with, your friends, the people in your apartment, or the family members.

You need a complete list of all the participants.

2. Write down everything that was spent

Don’t forget any expenses, like hotel bookings, dinner, or taxi fares.

For each item, you need to write three things:

How much the item or the activity cost.
Who paid for it.
Who benefits from that cost (sometimes only three out of four people went to that museum or stays in the hotel)

Note: you can’t sum up everything now, unless all the activities and items are shared by all the participants.

3. Calculate each person’s fair share

For every single bill, you need to divide the total cost by the number of people sharing it.

This gives you the exact amount that everyone owes for that one thing.

Example: If you are four people and the dinner cost $60 but only 3 people shared it, then everyone needs to pay $20.

4. Keep track of the expenses

As you go, keep track of two things:

How much they have paid out of their own pocket.
How much they owe in total.

A basic spreadsheet or the expense split calculator above will work perfectly for this.

5. The total

When your trip or the event is over it is the moment of truth.

See what each person should have paid (all their shares added up) to what they actually paid.
The difference tells you who needs to send money and who needs to get a refund. This makes the final payment clear and easy, so everyone walks away feeling like the split was fair.
