💱Currency Gain/Loss Calculator

Calculate currency gain or loss on overseas stock by exchange rate change

How Currency Moves Affect Foreign Stock Returns

When you invest in foreign stocks, your final return in home currency combines both the stock performance and the exchange rate movement. This calculator separates and combines both effects so you can see what each contributed to your overall result.

Total return (home currency) = (1 + stock return/100) × (current FX rate / purchase FX rate) − 1. If the foreign currency strengthens against your home currency, it amplifies your gains (and losses). If it weakens, it subtracts from your stock return.

To isolate the FX impact, enter 0 for stock return. To see combined returns, enter the actual stock gain or loss percentage.

Frequently Asked Questions

How do I use this for USD/EUR investments from the UK?

Enter the GBP/USD or GBP/EUR rate at purchase and the current rate. Your investment amount would be in GBP. The calculator works for any currency pair.

Can a stock go up but still lose money in my currency?

Yes. If your home currency strengthens significantly against the investment currency, the exchange loss can exceed the stock gain. For example, a 10% stock gain with a 15% currency loss results in roughly a -6% total return.
