How to Use the Exchange Rate Change Calculator
When traveling abroad, holding a foreign currency deposit, or investing in foreign assets, exchange rate swings create gains and losses. Enter the rate at the time you exchanged or bought the currency and the current rate, and this tool instantly shows the change rate along with the FX gain or loss based on the amount you're holding.
Change rate (%) = (current rate − past rate) ÷ past rate × 100, and FX gain = foreign currency amount × (current rate − past rate). For example, if you bought $1,000 at a rate of 1.05 and it's now 1.10, the change rate is about 4.76% and your gain is $50. If the rate falls, the same formula shows a loss instead.
