When you spend Australian dollars overseas, the exchange rate is only part of the cost. A card with a favorable conversion rate can still be more expensive once international transaction fees, ATM charges or a merchant’s currency conversion are included.
The most useful comparison is the total amount in Australian dollars you expect to pay for the same foreign-currency purchase. Rates can change between a purchase and processing, so treat an estimate as a guide unless the provider guarantees the rate.
Destaques
- Compare the total Australian-dollar cost, including both the exchange rate and applicable fees.
- Check which way a rate is quoted before multiplying or dividing.
- When offered a choice at a terminal or ATM, compare the merchant’s Australian-dollar conversion with the expected cost of paying in local currency.
- Budget for rate changes and check the final amount when the transaction settles.
How do you compare exchange rates for an overseas purchase?
Start with one specific purchase amount, such as a €100 hotel bill. Obtain a quote from each payment option for that same amount at roughly the same time. Include any percentage or fixed fees, and compare the final cost in Australian dollars.
Read the direction of each rate carefully. If the rate is expressed as 1 Australian dollar = 0.60 euros, divide the euro price by 0.60 to estimate the Australian-dollar cost before fees. If it is expressed as 1 euro = 1.6667 Australian dollars, multiply the euro price by 1.6667 instead.
For a rate quoted as foreign currency per Australian dollar, a higher number generally means you receive more foreign currency for each Australian dollar before fees. The reverse applies when the rate is quoted as Australian dollars per unit of foreign currency. A search engine’s reference rate can be a useful benchmark, but it is not necessarily the rate available to you.
What does a rate difference cost in practice?
These hypothetical figures illustrate how to compare two options; they are not current quotes:
- Option A: At €0.60 per A$1, a €100 purchase costs approximately A$166.67. With a hypothetical 3% international transaction fee on that converted amount, the total is A$171.67.
- Option B: At €0.59 per A$1, the same purchase costs approximately A$169.49. With no additional transaction fee in this example, the total is A$169.49.
Option B has the less favorable quoted rate but costs about A$2.18 less after the stated fee. Actual providers can calculate fees differently, so check the terms and avoid adding a fee twice if a quote already includes it. For cash or prepaid currency, ask how much foreign currency you will receive after all fees for the Australian dollars you pay.
Which fees should Australian travelers check?
Look at the product’s fee schedule and the quote for the exact transaction. A rate margin may already be built into the conversion rate, while a separate international transaction fee may appear on your statement. A cash exchange or prepaid card may also have loading, withdrawal, account or inactivity fees. Calculate costs for the way you expect to use the product, including how often you plan to withdraw cash.
An overseas ATM operator may charge its own fee in addition to any charge from your card provider. With a credit card, a cash withdrawal can also be treated as a cash advance: Moneysmart says a transaction fee usually applies and interest is usually charged from the withdrawal date. Check your card’s terms before relying on it for cash.
Even a purchase shown in Australian dollars can attract an international transaction fee, depending on the card and how the payment is processed. Moneysmart’s definition notes that the fee may apply to some overseas transactions denominated in Australian dollars. This can matter when shopping online as well as traveling.
Should you pay in Australian dollars or the local currency?
A foreign merchant or ATM may offer to convert the transaction into Australian dollars immediately. This is called dynamic currency conversion, or DCC. Its appeal is that you can see an Australian-dollar amount before accepting, but the offer can include a markup or other fees.
Choosing the local currency generally leaves conversion to your card’s usual arrangements and avoids the merchant’s conversion markup. It does not necessarily remove your card issuer’s international transaction fee, and the final rate may not be known at the terminal. Compare the displayed Australian-dollar DCC amount with your best estimate of the local-currency option, including your issuer’s fees; the cheaper choice depends on the terms.
Visa’s DCC guidance says its merchants and ATMs should display the amounts in both currencies, the conversion rate and any additional fees or markup, and allow the cardholder to accept or decline conversion. Check the screen and receipt before confirming.
What happens if the Australian dollar changes before a payment settles?
If the Australian dollar buys less of the foreign currency when your transaction is converted, the Australian-dollar cost will generally rise; if it buys more, the cost will generally fall. The rate applicable to your transaction can depend on the provider and processing date, so a pending amount can differ from the final posted amount. A prepaid foreign-currency balance may instead reflect the rate accepted when you loaded it, subject to the product’s terms and sufficient balance.
For a trip or a large overseas purchase, estimate costs using today’s available quotes, leave a buffer for exchange-rate movement and fees, and check whether a quoted rate is guaranteed and for how long. If you need to exchange cash, compare the actual amount you will receive rather than a headline rate alone. Moneysmart recommends checking both the rate and fees when comparing currency transfers; the same total-cost discipline is useful for purchases.
After paying, review the settled transaction and any separate fees against your estimate. If you chose local currency but the merchant converted the charge anyway, contact your card issuer and retain the receipt. No one can reliably predict the exchange rate you will receive on a future, unguaranteed transaction, so revisit the comparison when you are ready to pay.
Frequently asked questions
Is the best exchange rate always the cheapest option?
No. A better rate can be outweighed by transaction, ATM or other fees. Compare the total Australian-dollar cost for the same purchase.
Can I be charged an international fee on an Australian-dollar purchase?
Yes. Depending on your provider’s terms and how the transaction is processed, an international fee may apply even when the charge is in Australian dollars.
Should I accept an ATM’s Australian-dollar conversion?
Check the displayed rate, markup and total first. Declining conversion and choosing the local currency avoids the ATM’s conversion, but your card’s own rate and fees may still apply.
