Understanding Westpac Exchange Rates
Whether you are planning an overseas holiday, purchasing goods from international retailers, or sending money to family abroad, understanding how currency conversion works is essential. This Westpac Exchange Rates Calculator tool helps you estimate the value of your Australian Dollars (AUD) against major global currencies like the US Dollar (USD), Euro (EUR), and British Pound (GBP).
How Exchange Rates Work
Exchange rates fluctuate constantly based on global financial markets. Banks like Westpac generally offer different rates depending on the service you are using:
Telegraphic Transfer (TT) Rate: Used when sending money electronically to an overseas bank account. This is often the most common rate for International Money Transfers (IMT).
Cash Rate: Applied when you buy foreign cash over the counter at a branch. This rate usually has a higher margin to cover the cost of handling physical notes.
Card Rate: Used when you make a purchase overseas using your Westpac Debit or Credit card.
Factors That Cost You Money
When converting currency, the exchange rate is not the only factor determining how much foreign currency you receive. You must also consider:
The Spread: This is the difference between the wholesale "mid-market" rate and the "retail" rate the bank offers you. The bank buys currency at a wholesale price and sells it to you at a retail price.
Transfer Fees: Westpac may charge a flat fee for international transfers, though some online transfers via the app may have reduced or waived fees depending on the destination and account type.
Correspondent Bank Fees: When sending money via SWIFT, intermediary banks may deduct small fees from the total amount before it reaches the recipient.
Using This Calculator
To use the tool above, simply enter the amount you wish to convert. Select your source currency (usually AUD if you are sending money from Australia) and your target currency. If you know there is a fixed transaction fee (e.g., $10 AUD), enter that in the fee field to see exactly how much money will actually be converted after costs.
