Understanding Cross Currency Exchange Rates
Cross currency exchange rates, often referred to as cross rates, are the exchange rates between two currencies that are not the US dollar (USD).
In most international financial markets, the USD serves as an intermediary currency for many transactions. This means that if you want to exchange
a currency like the Australian Dollar (AUD) directly for the Canadian Dollar (CAD), the market might not always provide a direct quote. Instead,
the exchange might happen indirectly through the USD.
The process involves two legs:
- Converting the base currency to the intermediary currency (usually USD).
- Converting the intermediary currency to the desired quote currency.
This calculator simplifies the process by assuming you have the direct exchange rate between your base currency and your desired quote currency.
How to Calculate:
The calculation is straightforward once you have the necessary exchange rate. The formula used here is:
Amount in Quote Currency = Amount in Base Currency * Exchange Rate (1 Base = X Quote)
For example, if you have 1,000 US Dollars (USD) and the exchange rate to Euros (EUR) is 1 USD = 0.92 EUR, then the calculation is:
1,000 USD * 0.92 EUR/USD = 920 EUR.
In this calculator, you provide the amount in your base currency, the codes for your base and quote currencies (for context), and the direct exchange rate.
The calculator then outputs the equivalent amount in the quote currency.
Key Terms:
- Base Currency: The first currency in a currency pair (e.g., USD in USD/EUR). This is the currency you are converting *from*.
- Quote Currency: The second currency in a currency pair (e.g., EUR in USD/EUR). This is the currency you are converting *to*.
- Exchange Rate: The value of one currency for the purpose of trading it for another. In this calculator, it's expressed as how many units of the quote currency you get for one unit of the base currency.
