Exchange Rate Tool
Convert between currencies and see the impact on your net worth
Change one currency into another and see what you get
Free · No sign-up · Updates as you typeAn exchange rate is just a price: what one unit of the money you hold buys in the money you want. Type an amount and the rate, and you see what lands in the other currency, plus the same rate read backwards.
You bring the rate: this page never fetches rates, so no number on it can quietly go out of date. Copy today's rate from your banking app, your broker, or a neutral reference such as the European Central Bank, which publishes euro reference rates every working day. The rate filled in below is an illustration to show you how the tool works, not a quote for today.

The sum you hold today, e.g. 1,000.
Replace the example with today's rate.
What your 1,000.00 USD becomes, at the rate you typed
920.00 EUR
In plain terms: 1,000.00 USD at a rate of 0.92 gives you 920.00 EUR. Read the other way round, 1 EUR costs 1.086957 USD.
1 USD buys

If the rate moves before you convert
Rates drift every day, so it helps to see the size of the swing. Here is the same amount converted at rates a little above and below yours.
| Rate move | Rate | You get | Difference |
|---|---|---|---|
| -5% | 0.874 | 874.00 EUR | -46.00 EUR |
| -2% | 0.9016 | 901.60 EUR | -18.40 EUR |
| Your rate | 0.92 | 920.00 EUR | 0.00 EUR |
| +2% | 0.9384 | 938.40 EUR | +18.40 EUR |
| +5% | 0.966 | 966.00 EUR | +46.00 EUR |
Insight: This conversion uses the rate you entered. In practice the rate your bank or broker gives you is usually a little worse than the mid-market rate, because of the spread. When you hold assets in more than one currency, exchange rate moves change your net worth even when the underlying prices stay the same.
Check what your bank's rate really costs you
The rate you see in the news is the mid-market rate, the fair midpoint. Banks and transfer apps hand you a slightly worse one and often add a fixed fee on top. Type the rate you were quoted and any fee, and the gap turns into real money.
Same direction as above: EUR for 1 USD.

An exchange rate is simply the price of one currency expressed in terms of another. This tool converts an amount from a source currency into a target currency using a rate you supply, so you can model any rate you like, the mid-market rate, the rate your bank quoted, or a hypothetical future rate for scenario planning.
Converted = Amount × Rate
Step 1: Pick the currency you hold and the one you want, then type the amount you are changing.
Step 2: Replace the example rate with today's, taken from your bank or a rate source you trust. The answer updates as you type.
Step 3: Read the amount you get, the same rate turned around, and how the answer changes if the rate moves. Then add your bank's rate in the second card to see what converting really costs.
What Is an Exchange Rate?
An exchange rate is the price at which one currency can be exchanged for another. If the EUR/USD rate is 1.08, it means one euro buys 1.08 US dollars. Quoted the other way around, the USD/EUR rate would be roughly 0.93, the reciprocal. Exchange rates move constantly as supply and demand for each currency shift in response to interest rates, inflation, trade flows, central bank policy, and market sentiment.
For anyone who holds assets, earns income, or spends money in more than one currency, the exchange rate is not an abstraction, it directly determines how much your money is worth when you bring it home. That is why understanding rates, and the difference between the headline rate and the rate you actually receive, is a core part of managing wealth across borders.
Mid-Market Rate vs the Rate You Actually Pay
Your cost = (Mid-market − Quoted rate) + fees
The mid-market rate, also called the interbank rate, is the midpoint between the buy and sell prices of a currency pair in the wholesale market. It is the rate you see quoted on financial news sites and search engines, and it is the fairest reference point. However, it is rarely the rate you receive. Banks, brokers, and money-transfer services add a margin, the spread, on top of the mid-market rate, and may layer on a fixed fee as well.
A spread of one or two percent can sound small, but on large transfers or frequent transactions it compounds into a meaningful drag on returns. When you compare providers, do not just look at the advertised fee, compare the actual exchange rate offered against the mid-market rate for the same moment. The gap between the two is the true cost, and the second card above turns it into a figure in your own money: put the mid-market rate in the converter, the quoted rate and the fee in the comparison, and read what the conversion really takes from you.
How Exchange Rates Affect Your Net Worth
For an international investor, currency movements are a second source of return that sits on top of the performance of the underlying assets. Imagine a euro-based investor who buys US stocks. Even if those stocks rise in dollar terms, the investor can still end up worse off if the dollar weakens against the euro over the holding period. The reverse is also true: a falling home currency can boost the value of foreign holdings when translated back. This is currency exposure, and it can either amplify or erode your real wealth.
The disciplined way to handle this is base-currency thinking: pick a single currency, usually the one you live and spend in, and convert every asset and liability into it so that your net worth is measured on one consistent ruler. A portfolio that looks diversified across countries may carry concentrated currency risk once you translate it all into your base currency. Reviewing holdings in base-currency terms reveals that hidden risk and helps you decide whether to hedge it.

Measure your currency exposure to see how much of your net worth sits in each currency, and then use the FX impact calculator to model how a specific exchange rate move would change your wealth in base-currency terms.
Frequently Asked Questions About the Exchange Rate Tool
The mid-market rate (also called the interbank rate) is the midpoint between the buy and sell prices of two currencies in the global market. It is the rate you see on financial news and search engines. The rate you actually pay when exchanging money is almost always worse, because banks, brokers, and money-transfer services add a spread or margin on top of the mid-market rate and may also charge a fixed fee. The gap between the two is your real cost of converting.
If you hold assets in currencies other than your home currency, exchange rate movements change your net worth even when the underlying asset prices do not move. For example, a US stock can rise in dollar terms while a euro-based investor still loses money if the dollar weakens against the euro over the same period. Choosing a single base currency and converting all holdings into it gives you a true, consistent picture of your wealth.
Because a rate we stored yesterday would quietly be wrong today, and you would have no way of knowing. You type the rate, so you always know exactly how old it is and where it came from. It also lets you model the rate that actually matters to you: the one your bank quoted, not the headline one. Copy it from your banking app, from your broker, or from a neutral reference such as the European Central Bank, which publishes euro reference rates every working day. If you want rates fetched for you across a whole portfolio, that is what the Worthmap app and the currency exposure tool do.
Read it as a price: the rate is what one unit of the currency you hold buys in the currency you want. If you have dollars and want euros, a rate of 0.92 means one dollar buys 0.92 euros. The label above the rate field spells this out for the pair you picked, and the inverse rate underneath shows the same relationship the other way round. If you have the rate quoted the opposite way, use the swap button and the tool turns it around for you.
