A restaurant receipt may say €120 while the card statement says $134.67. Another traveller paid with cash withdrawn from an ATM that charged two separate fees. When a group mixes currencies, cards and cash, “split the receipt” may not fully describe the real cost.
Choose one group currency
Use the currency in which the group wants to understand and settle balances. Every original expense can remain visible in its local currency while the comparison uses one common base.
Choose a consistent conversion rule
Options include the transaction's final card-statement amount, a trusted reference rate on the expense date, or an agreed custom rate. Consistency matters more than chasing the theoretically perfect rate.
If one person's card rate is used, include the real settled amount only after it is known. Do not mix that method with mid-market rates for other people without telling the group.
Decide which fees are shared
- Mandatory merchant surcharge: usually part of the shared purchase.
- Foreign transaction fee: often personal to the card choice unless agreed otherwise.
- ATM fee for shared cash: reasonable to divide among users of that cash.
- Dynamic currency conversion markup: document the actual charged amount.
Track shared cash as it is spent
Do not treat an ATM withdrawal as an expense if the cash is still held. Record the actual meals, taxis and tickets paid from it, or treat the withdrawal as a shared cash pot with a clear final balance.
Handle refunds in the same currency logic
A refund may arrive at a different exchange rate. Use the actual returned amount or the same agreed reference method, and document any unavoidable difference rather than hiding it in another expense.
How Splitwin handles the record
Splitwin supports multi-currency expenses, live conversion and custom exchange rates. Original amounts remain available for reference while group calculations and charts can be normalised to the chosen currency.
Frequently asked questions
Which exchange rate should friends use?
Use one transparent rule consistently: the actual card amount, a trusted reference rate, or an agreed custom rate.
Should foreign transaction fees be shared?
Usually they remain with the cardholder unless using that card was a group decision or the fee was unavoidable.
Is an ATM withdrawal itself an expense?
Not necessarily. It converts money into cash; record what the cash ultimately buys or reconcile the cash pot.
Why can a refund differ from the original converted amount?
Exchange rates and provider fees may change between the purchase and refund dates.
