Currency Exposure Calculator
How much is currency movement costing your net worth?
Your money, by currency
Free · No sign-up · Updates as you type
The currency you live and spend in. Everything is converted into this so you see your wealth the way you actually experience it.
How much you hold in each currency
Type what you own, in the currency each thing is priced in. Leave out what you owe.
What to count, and what is left out
Count cash, investments, property and pensions. Use the currency the asset is priced in, not the one you paid with: a US-listed fund counts as USD even if you bought it in euros. A loan in another currency is not counted here, yet it moves with exchange rates too: if that currency rises against yours, the loan costs you more.
53.7% of your money, USD 57,925, moves when exchange rates move
Your money adds up to USD 107,925. USD 50,000 of it is in USD and stays put. The other USD 57,925 is spread over 2 currencies, the biggest being EUR with USD 32,609. If EUR alone falls 10% against USD, you lose USD 3,261; if it rises 10%, you gain the same.
The numbers behind that
What your money adds up to
Every amount above, converted into USD at today's rates.
USD 107,925
Money in your home currency
46.3% of the total. It is already in USD, so exchange rates do not change what it is worth to you.
USD 50,000
Money that moves with exchange rates
53.7% of the total, held in 2 other currencies. In USD it is worth more when they rise and less when they fall.
USD 57,925
The biggest part of it: EUR
30.2% of the total. A 10% move in EUR changes your total by USD 3,261, up or down.
USD 32,609
What changes it
Every USD 1,000 you move from another currency into USD lowers the share that moves by 1.0 percentage points. That is arithmetic, not a recommendation: money held in other currencies also spreads your risk.

What a currency move does to your total
Each row shows the gain or loss to your total wealth, in USD, if that one currency moves against your home currency while the others stay put. Your largest exposure is highlighted.
| Currency | -15% | -10% | -5% | +5% | +10% | +15% |
|---|---|---|---|---|---|---|
| EUR (30.2%) | -USD 4,891 | -USD 3,261 | -USD 1,630 | +USD 1,630 | +USD 3,261 | +USD 4,891 |
| GBP (23.5%) | -USD 3,797 | -USD 2,532 | -USD 1,266 | +USD 1,266 | +USD 2,532 | +USD 3,797 |
A real market often moves several currencies at once, so treat each row as one isolated what-if.
What happens if one currency moves
If EUR drops 10% against USD:
Your EUR holdings would change by:
-USD 3,261
Your EUR 30,000 would be worth USD 29,348 instead of USD 32,609, and your total USD 104,664 instead of USD 107,925.

Currency exposure, sometimes called FX exposure or foreign exchange risk, refers to the potential for your wealth to gain or lose value because of changes in exchange rates between currencies. If you hold assets, earn income, or have liabilities in more than one currency, you have currency exposure whether you realise it or not.
For international investors, expats, and digital nomads, currency exposure is one of the most overlooked risks in wealth management. You might see your portfolio gaining value in one currency while simultaneously losing purchasing power in another. A stock portfolio that is up 12% in US dollars might only be up 4% when converted back to Australian dollars if the AUD strengthened during that same period, or it might be up 20% if the AUD weakened.
The challenge is that most financial tools only show your wealth in a single currency, hiding the real effect of exchange rate movements. This calculator is designed to make that hidden risk visible, so you can make informed decisions about how much of your wealth is exposed to foreign currency fluctuations and what that means in practical terms.
How Currency Exposure Affects Your Net Worth
The impact of currency movements on your net worth depends on two factors: how much of your wealth is denominated in foreign currencies, and how much those exchange rates move.
Consider a simple example. An investor based in New Zealand holds NZ$100,000 in a US stock index fund. At the time of purchase, 1 NZD buys 0.62 USD, so the fund is worth US$62,000. A year later the fund has risen 10 percent to US$68,200, but the New Zealand dollar has strengthened: 1 NZD now buys 0.70 USD. Converted back, the holding is worth NZ$97,429. The fund gained 10 percent in US dollars, yet counted in New Zealand dollars the investor is down 2.6 percent.
This is not a rare or extreme situation. Movements of 5-15% in major currency pairs within a single year are common. For anyone with significant wealth outside their home currency, understanding this exposure is not optional, it is essential to accurate financial planning.
Who Needs a Currency Exposure Calculator?
This tool is designed for anyone whose financial life spans more than one currency. That includes expats living in one country while holding investments or pensions in another, digital nomads earning income in one currency while spending in several others, international investors with portfolios across US, European, Asian, or Australian markets, business owners who invoice or pay costs in foreign currencies, and retirees drawing from pensions denominated in a different currency to their cost of living.
How to Use This Calculator
Start by entering what you hold in each currency. The calculator loads daily reference rates itself when you open the page and converts everything into your home currency, then shows the split and how much is in other currencies.
The slider under the result tests one currency at a time. What happens to your total if the US dollar falls 10% against your home currency? What if the euro rises 5%? The table above the slider shows the same for every currency you hold. Both show what exchange rates alone would do to your money, separate from how the investments themselves perform.
Strategies for Managing Currency Exposure
Once you understand your exposure, there are several approaches to managing it. The right strategy depends on your time horizon, risk tolerance, and financial goals.
One common approach is natural hedging, which involves matching the currency of your assets to the currency of your future expenses. If you plan to retire in Europe, holding a portion of your portfolio in EUR-denominated assets reduces the risk that a weakening EUR would hurt your purchasing power at retirement.
Another option is using currency-hedged investment funds. Many ETF providers offer hedged versions of their international funds that aim to neutralise the impact of exchange rate movements. These come with a small cost (typically 0.3-1.0% per year depending on interest rate differentials), but they remove the uncertainty of currency swings.
Regardless of which approach you take, the first step is always understanding your current exposure, which is exactly what this calculator helps you do.
Frequently Asked Questions
Currency exposure risk for expats is the possibility that changes in exchange rates between your home currency and the currencies of the countries where you live, work, or invest will reduce your purchasing power or total wealth. For example, if you earn income in Thai baht but your long-term savings target is in euros, a strengthening euro reduces the real value of every baht you save. The risk is not just about losing money on investments, it affects your salary, your savings, your pension, and your cost of living simultaneously. Most expats underestimate this risk because they mentally account in one currency while actually living across several.
List everything you own in currencies other than your base currency: bank accounts, investments, property, pensions and any money owed to you. Convert each to your base currency at today's exchange rates, then add them up. The share of the total that sits outside your home currency is your foreign exposure. This calculator does that for you: enter what you hold in each currency, pick your base, and it shows the split and what a given exchange rate move would do to your total. It counts only what you own. A debt in a foreign currency is exposure too, in the other direction: if that currency rises against yours, the debt grows in your money. So if you have a foreign mortgage or loan, keep it in mind next to the result.
There is no single safe share, and no rule that fits everyone. It depends on three things: where you will spend the money, when you will need it, and which currency your bills and debts are in. Money you will need soon in your home currency is where a move in exchange rates hurts most, because you may have to convert it at whatever the rate is that day. Money you will spend abroad, or that pays bills and debts in another currency, is better held in that currency. So the same split can suit one person and not another.
Currency exposure affects your net worth every day, even when you are not buying or selling anything. If you hold $50,000 in US stocks and your home currency is GBP, the GBP value of those stocks changes with every movement in the USD/GBP rate, even if the dollar price of the stocks stays flat. Most net worth trackers show assets in a single currency and update the converted value using current rates, meaning your net worth can fluctuate significantly without any change in your investment performance. Understanding your exposure lets you separate real investment performance from currency effects, which is essential for accurate financial planning.
Currency exposure is the degree to which your wealth is subject to exchange rate movements, it is the risk itself. Currency hedging is a strategy to reduce or neutralise that risk, typically through financial instruments such as forward contracts, currency ETFs, or hedged fund share classes that offset gains or losses from exchange rate movements. A hedged position means that if the currency your assets are in falls 10%, your hedging instrument gains approximately 10%, keeping the net value stable. However, hedging comes at a cost (typically 0.3-1.5% per year depending on interest rate differentials) and is not always appropriate for long investment horizons. This calculator helps you understand your current exposure, whether to hedge any portion of it is a separate decision.
For most investors, reviewing currency exposure quarterly or when major exchange rate movements occur (5%+ shifts) is sufficient. If you actively trade currencies or have very large foreign-denominated holdings, more frequent monitoring may be appropriate.
You do not type any rate. When you open the page, the calculator loads reference rates from exchangerate-api.com, which publishes them once a day. They are not live market prices, and the rate a bank or a card gives you will differ, because each adds its own margin. If the rates cannot be loaded, a notice at the top of the page says so and the calculator uses estimated rates instead. To see what a different rate would do to your total, use the slider under the result.
No. This tool focuses specifically on currency exposure, how exchange rate changes affect the value of your existing holdings. It does not factor in the underlying investment performance of your assets.
The calculator is built for personal savings and investments, but the same idea works for a small business. Enter what the business holds or is owed in each currency, such as cash and unpaid customer invoices. Money the business owes in a foreign currency, like supplier bills, is not counted here, so look at it separately.
