Best Ways to Save on Currency Exchange: Cash, Cards and Transfers
Compare the total cost of foreign cash, cards, ATMs and international transfers, and avoid common currency-exchange mark-ups.
Currency exchange guide · Reviewed July 2026
The cheapest method depends on what the money is for
Foreign cash, card purchases, ATM withdrawals and international transfers use different pricing. A useful comparison starts with the same currencies, amount and time, then checks the final foreign-currency amount after the retail exchange rate and every fee.
The most reliable saving
Compare the total price instead of choosing a “fee-free” offer. A provider can charge no separate commission while building its cost into the customer exchange rate.
Choose by use case
Four ways to obtain or spend foreign currency
Cash
Pre-ordered foreign cash
Useful for arrival, tips and cash-led destinations. Compare how much foreign currency is supplied for the same home-currency spend, including commission, delivery or collection.
Card
Debit, credit or travel card
Convenient for purchases, but pricing can include an issuer international transaction fee, a conversion fee, a card-network rate or a provider exchange-rate margin.
ATM
Cash withdrawn overseas
Can reduce the need to carry cash from home. Check the card issuer’s conversion and withdrawal charges plus any separate ATM-operator surcharge.
Send
International transfer
Appropriate for a bank-account payment, property purchase or family support—not ordinary holiday spending. Compare the final recipient amount and possible bank deductions.
| Method | Compare this result | Common hidden cost |
|---|---|---|
| Foreign cash | Foreign notes received | Retail-rate margin, commission, delivery or airport pricing |
| Card purchase | Home-currency amount debited | Issuer fee, conversion cost or dynamic currency conversion |
| ATM withdrawal | Total home-currency cost of cash received | Issuer fee plus ATM-owner fee and DCC |
| Money transfer | Amount the recipient gets | Rate margin, transfer fee and intermediary or receiving-bank deductions |
Foreign notes
Order before reaching the airport
The ACCC advises travellers to shop around and buy foreign cash before getting to the airport. Airport exchange is convenient but can be more expensive than non-airport alternatives. That does not make one non-airport supplier universally cheapest: rates vary by currency, amount, location and time.
Compare simultaneously
Use the same amount and time
Retail rates move. Compare suppliers on the same day at approximately the same time and look at the foreign notes received, not just the displayed rate.
Avoid excess cash
Estimate a practical amount
Too little may force an expensive last-minute exchange; too much creates theft risk and another conversion cost when changing leftovers back.
Live cash comparison
Compare current foreign-cash rates
Use the same home-currency amount and destination currency. Review rate timestamps, provider fees and delivery or collection conditions before ordering.
Purchases abroad
A waived card fee is only one part of the price
Issuer
International transaction fee
Some issuers add a percentage fee for overseas or foreign-currency transactions. It may apply even when an overseas merchant displays your home currency.
Rate
Conversion method
A bank card may use the applicable card-network rate. A multi-currency provider may use a reference rate plus a disclosed fee, while a prepaid card may use a retail load rate.
DCC
Merchant conversion
Dynamic currency conversion lets a merchant convert the purchase into your home currency. The displayed certainty can include a mark-up.
At checkout
Choose the destination’s local currency unless you have compared and deliberately accepted the merchant’s home-currency conversion. Your own issuer’s usual fees can still apply.
Compare card types in Travel Money: Cash, Debit, Credit or Multi-Currency Card? and use the travel-card checklist.
Cash overseas
Treat ATM cost as three layers
Card conversion
The withdrawal may require conversion under the card’s exchange-rate and fee rules.
Issuer withdrawal fee
The card provider may charge a fixed fee, percentage, or a fee after an allowance is exceeded.
ATM operator fee
The machine owner can add a separate surcharge. Check the screen before confirming and cancel if the cost is unacceptable.
Fewer, sensibly sized withdrawals can reduce repeated fixed charges, but avoid carrying more cash than can be stored safely. Do not use a credit card for cash without checking cash-advance fees and when interest starts.
Bank-account payments
Compare the recipient amount
For an international money transfer, the advertised fee alone does not show value. Match the sending amount, currencies, payment method, recipient country and quote time. Then compare what arrives and whether that amount is guaranteed or could be reduced by another bank.
Live transfer comparison
Compare exchange rate, fee and delivery
Confirm transfer limits, funding charges, delivery estimates and possible correspondent or recipient-bank fees before paying.

Before converting
Seven ways to avoid unnecessary cost
Decision checklist
Compare before confirming
- Define whether you need cash, a purchase, an ATM withdrawal or a bank transfer.
- Compare identical currencies and amounts at approximately the same time.
- Use the final foreign amount or home-currency debit—not “zero fee”—as the result.
- Include card, funding, delivery, ATM and receiving-bank charges.
- Order necessary cash before the airport rather than relying on departure-gate exchange.
- Choose local currency at merchants and ATMs unless intentionally accepting DCC.
- Keep a separate backup payment method; the lowest-cost option is not useful if it fails.
Bottom line
Compare the complete transaction
There is no permanent best currency-exchange provider or method. Match the product to the purpose, compare the total result, and recheck live pricing immediately before exchanging.
