Weighing FX Hedge Cost Against Currency Risk
When you invest in foreign assets, currency swings can matter just as much as the price of the asset itself. Hedging with forwards or currency swaps removes that exchange-rate risk — but it isn't free. You pay a cost roughly equal to the interest rate differential between your home currency and the foreign currency, so the real question isn't "should I hedge," it's "does the expected currency move justify what the hedge costs?"
This calculator takes your foreign investment principal, the annual hedge cost rate, and your holding period, and converts them into a total dollar hedge cost and a breakeven currency move — the percentage move you'd need to see, working against an unhedged position, before hedging would have been worth it. If you also enter how much you expect the currency to move against you, the calculator compares that estimate to the breakeven point and flags whether hedging or staying unhedged looks more favorable.
Currency movements are notoriously hard to predict, and real hedge costs vary by instrument, maturity, and financial institution. Treat this result as a simplified planning estimate, and confirm the actual forward points and fees with your broker before committing to a hedge.
Frequently Asked Questions
Hedging with forwards or currency swaps removes exchange-rate risk, but you pay a cost roughly equal to the interest rate differential between the two currencies — the higher your home country's rates are relative to the foreign currency, the more the hedge typically costs.
A large breakeven percentage means the exchange rate has to move a lot against an unhedged position before that cost would outweigh the hedge. If you don't expect the currency to move that much, staying unhedged may make more sense.
No. This is a simplified estimate. Actual hedge costs vary by product, maturity, and provider, so confirm the real forward points and fees with your broker or bank before making a decision.
