FX Gain/Loss

The FX Gain/Loss Calculator decomposes the total return on a foreign-currency investment into two components: the underlying asset return and the currency return. A stock that gained 15% in its local currency may show 20% or 10% returns in your home currency depending on FX movements. Enter the asset purchase and current values in the foreign currency, along with the exchange rates at purchase and now. The calculator shows the asset return, currency return, and total return in your home currency, making it clear how much of your gain or loss comes from each source. This decomposition is critical for international investors. Understanding FX contribution helps you decide whether to hedge currency risk, overweight or underweight foreign assets, and set realistic return expectations for your globally diversified portfolio.
