For each expense, divide the amount among only the people who took part, add up each person's shares, and subtract that from what they paid. Positive balances are owed money, negative balances owe it. In a five person trip with 960 of shared costs, Mira is owed 292 and the other four pay her 148, 98, 28 and 18. Private items, such as a gift, are left out. In Here & Home you pick just me, everyone or specific members on each entry.
When an equal split is unfair
Splitting everything equally by the number of people only works if everyone did everything. On real trips they do not. Some people skip the boat trip, one person is picked up from the airport in a different car, and someone buys a gift only for themselves. If every cost is divided by everyone, people end up subsidising things they did not use, and arguments follow.
The fix is to record who shared each expense, and split each one only among those people.
The method
- For each expense, note who paid, the amount and who shared it.
- Divide the amount by the number of people who shared it. That is each sharer's cut.
- Add up each person's cuts across all expenses. That is their total share.
- Net balance = paid − share. Positive means they are owed. Negative means they owe.
- Match payers and owers until every balance is zero.
Worked example, five people
Mira, Noah, Ola, Pia and Raj share a holiday flat. These are the shared costs.
| Expense | Paid by | Amount | Each sharer pays |
|---|---|---|---|
| Apartment, 5 nights | Mira | 500 | 100 each |
| Groceries | Noah | 90 | 18 each |
| Harbour dinner | Ola | 150 | 30 each |
| Boat trip (4 went) | Pia | 160 | 40 each (Mira, Noah, Pia, Raj) |
| Airport taxi (3 shared) | Raj | 60 | 20 each (Mira, Ola, Raj) |
| Total shared | 960 | ||
Mira's share is 100 + 18 + 30 + 40 + 20 = 208. Noah took part in everything except the taxi, so his share is 100 + 18 + 30 + 40 = 188. Ola missed the boat trip, so her share is 100 + 18 + 30 + 20 = 168. Pia skipped the taxi, so hers is 188, and Raj did everything, so his is 208.
| Person | Paid | Share | Net balance |
|---|---|---|---|
| Mira | 500 | 208 | +292 (is owed) |
| Noah | 90 | 188 | −98 (owes) |
| Ola | 150 | 168 | −18 (owes) |
| Pia | 160 | 188 | −28 (owes) |
| Raj | 60 | 208 | −148 (owes) |
The balances add up to zero, which is the check that nothing is missing: 292 − 98 − 18 − 28 − 148 = 0.
Settle up: only Mira is owed money, so the other four pay her directly: Raj pays 148, Noah pays 98, Pia pays 28 and Ola pays 18. That is four payments, one fewer than the number of people.
Private items
Noah also bought a 30 souvenir for his mother. It is not part of the group's costs, so it is left out of every balance. If you included it in an equal split, everyone would owe a share of a gift they did not choose. Mark it private, and it stays on your phone and out of the settlement.
Doing it in Here & Home
- Save each expense as you spend it, in the local currency.
- For every entry choose just me (private), everyone, or specific members.
- Open Settle up. The app shows each person's spent and share, the net result and the fewest payments needed.
- The owner marks the trip Settled, and you can export a PDF for everyone.

Checking your numbers
- All balances should add up to zero.
- The total of everyone's shares should equal the total of shared costs (here, 208 + 188 + 168 + 188 + 208 = 960).
- The number of payments should never exceed the number of people minus one.
- If an exchange rate is involved, agree on one rate, or use each expense's saved value, so the group is working from the same numbers.
Questions people ask
How do I split expenses when not everyone shares everything?
Divide each expense only among the people who took part, add up each person's shares, and subtract that from what they paid.
What happens to private purchases?
They are left out of the group balance. Mark them private, or just me, and only you pay for them.
How do I know the split is right?
All net balances add up to zero, and total shares equal total shared costs.
How many payments will it take to settle?
No more than one fewer than the number of people.
Can I choose specific people for an expense in Here & Home?
Yes. Each entry can be just me, everyone or specific members.
Do amounts in different currencies cause problems?
Agree a single settle-up currency before you start, and use saved values so everyone works from the same numbers.
