Currencies and converted amounts
Understand the original amount, the trip currency and why a converted total can differ from your bank statement.
Original currency and trip currency
The original amount is what the receipt or payment says. The trip currency is the common unit used to compare costs inside your trip. When these differ, OnePlan can keep the original amount and currency alongside the converted amount and the conversion rate.
| Field | Meaning | Illustrative example |
|---|---|---|
| Original amount | What the purchase cost in the receipt currency | 1,000 THB |
| Trip currency | The currency used for the trip’s totals | VND |
| Converted amount | Original amount × the recorded rate | 750,000 VND at an example rate of 750 VND/THB |
Supported expense currencies
The current expense system supports USD, EUR, VND, THB, KRW, JPY, CNY, TWD, SGD and MYR. This is an expense-recording list; it does not mean merchant payments or wallet transfers support every currency on this list.
Choose the currency before entering the amount
- Use the receipt currency
If a meal cost 1,000 THB, enter 1,000 with THB, not 1,000 with VND.
- Review the converted total
Check that the size of the result makes sense. An incorrect currency can create a very large error even when the digits are right.
- Compare like with like
Compare the trip’s converted costs using the same trip currency. Keep external bank fees separate when they are not included in the receipt total.
Why the bank statement may differ
An expense conversion is for record keeping. A bank, card issuer or payment provider may use a different rate, charge fees or settle on another date. Do not treat the rate attached to a saved expense as a guaranteed payment rate.
For a merchant payment, review the amount, currency, exchange rate and any fees shown in that payment’s confirmation screen. For the website plan form, always check the displayed budget currency; an automatically selected default is not evidence of your home currency.
