There is no universally correct settlement currency. The right choice is the currency that makes the final transfers easiest and fairest for this particular group.
Treat the settlement currency as a payment decision, not as permission to rewrite every earlier expense.
Choose the currency that
- Most people can send and receive
- Creates the fewest conversion fees
- Matches the currency in which balances are already understood
- Can be agreed before transfers begin
01
When the home currency is best
If nearly everyone lives in the same country and uses the same banking system, settling in the shared home currency is usually easiest. People understand the amounts and can use familiar bank transfers.
This is especially useful when the trip is over and nobody still holds much of the destination currency.
02
When the destination currency is best
The local currency can work well when the group is still travelling, members already hold it or a local organizer paid most of the costs. It may also avoid converting a large outstanding balance twice.
Check whether everybody can actually send that currency without expensive international-transfer fees.
03
When a third currency makes sense
International groups sometimes share a currency that is neither the payer’s home currency nor the destination currency. Euros may be practical for friends spread across several European countries, for example.
Use a third currency only when it makes transfers simpler. Choosing it merely because it feels neutral can introduce another conversion and another opportunity for disagreement.
04
Decide once, then document the result
Agree the settlement currency before anyone sends money. Convert every member’s final net position on the same basis, then keep that result fixed while payments are made.
If exchange rates move the next day, do not recalculate completed transfers unless the group agreed to do so. A clear and consistent cut-off is usually fairer than chasing a theoretically perfect rate.
05
Compare the actual transfer routes
List where each person banks and which currencies they can receive without conversion. A currency that looks natural may be expensive if half the group must pay an international transfer fee or cannot receive it directly.
Compare the whole route, not only the advertised exchange rate. Transfer charges, receiving fees and a second conversion can matter more than a small difference in the headline rate.
06
Use a simple decision table
For a group living in one country, the shared home currency usually wins. For travelers who still hold the destination currency, local settlement can be efficient. For an international group, use the currency supported cheaply by the greatest number of members.
If two choices are similar, prefer the currency already used for the group balance. It reduces explanation and makes the settlement amounts easier to compare with what everyone has watched throughout the trip.
- Can everyone send it?
- Can everyone receive it?
- How many conversions are required?
- Will the amounts remain easy to verify?
07
Work through an international example
Suppose friends from Britain, France and Canada finish a trip in Denmark. Settling in Danish kroner may sound authentic, but all three may need another conversion after travelling home. Euros could be cheaper for two members, while pounds might suit only one.
There is no answer based on nationality alone. Compare the available accounts and fees, then calculate every final position using one rate and one cut-off time. The best choice is the one that loses the least money and creates the least friction.
08
Fix the rate at a clear moment
Choose the conversion basis when the group approves the settlement: for example, the app’s rate at that moment or the rate used throughout the trip. Save the resulting amounts so they do not change while transfers are in progress.
For a very large balance, the payer and recipient may agree to use the transfer provider’s live quote. Record the amount both sides accept before sending, rather than comparing different rate websites afterwards.
09
Keep proof of completion
Mark each payment complete only when the recipient confirms it arrived. International payments can remain pending, arrive short because of fees or be returned. A sent screenshot is helpful evidence but not the same as receipt.
If a fee is deducted en route, follow the group’s agreed fee rule and record the small correction. Once all net positions are zero, archive the settlement with the original expense history intact.

Keep the trip fair while it is happening
Squario keeps the original amount, converts it into the group currency and shows everyone where they stand—without waiting for the end of the trip.
