You’re standing in the middle of Old Town Square in Prague. The astronomical clock is about to chime, the smell of trdelník is everywhere, and you realize your wallet is full of Benjamins but zero koruna. You need to convert USD to Czech crown, and you need to do it fast. But here is the thing: Prague is beautiful, but it's also a minefield for the unsuspecting tourist trying to swap currency.
Honestly, it’s easy to mess this up.
Most people just walk into the first place with a big "0% Commission" sign. That is mistake number one. In the world of foreign exchange, "zero commission" usually just means "we hide our profit in a terrible exchange rate." If the mid-market rate—the one you see on Google or Reuters—says 1 dollar equals 24 CZK, and the shop is offering you 18 CZK, they aren't doing you a favor. They are taking a massive cut.
The Reality of the Czech Koruna (CZK)
The Czech Republic joined the EU way back in 2004, but they haven't adopted the Euro. They love their koruna. While some shops in the heavy tourist zones will take your Euros or even Dollars, they’ll give you change in crowns at a rate that would make a banker blush. You've gotta have local cash.
The Czech National Bank (Česká národní banka) manages the currency, and it's actually been one of the more stable performers in Central Europe lately. But stability doesn't mean it's cheap to get your hands on.

Why bother with cash anyway? Because while Prague is very digital-friendly, those tiny hospodas (pubs) in the Vinohrady district or the small crystal shops in Kutná Hora often have "cash only" signs tucked away near the register. You don't want to be the person awkwardly trying to pay for a 60-koruna Pilsner with a credit card that the machine won't read.
Where Most People Go Wrong
Let's talk about the airport. Václav Havel Airport is modern and efficient. It is also, arguably, one of the worst places on the planet to convert USD to Czech crown. The kiosks there rely on your desperation. You just landed, you're jet-lagged, and you need money for a taxi. They know this.
I’ve seen spreads at the airport as wide as 20%. That means if you exchange $500, you’re essentially handing $100 to the booth operator just for the privilege of standing there.
Then there are the street scammers. You might get approached by a guy—usually near a busy exchange office—offering a "better rate" than the shop. He’ll show you a roll of bills. They look like Czech crowns. They aren't. Usually, they are old Belarusian rubles or some other worthless currency that looks vaguely similar to the untrained eye. Never, under any circumstances, exchange money with a person on the street. It’s a classic Prague scam that Janek Rubeš from the "Honest Guide" YouTube channel has spent years documenting.
The Best Way to Get Crowns Today
If you want the most bang for your buck, your best bet is actually an ATM. But—and this is a huge "but"—you have to avoid the "tourist ATMs."
You’ll see them everywhere. They are bright blue and yellow, often branded as Euronet. These machines are designed to drain your account through dynamic currency conversion (DCC). When the machine asks if you want to be "charged in your home currency" or "continue with conversion," always say NO.
You want the machine to charge you in CZK.
By choosing to be charged in the local currency, you let your own bank back home handle the conversion. Since your bank actually wants to keep you as a customer, they’ll usually give you a rate much closer to the actual market value. Even with a small foreign transaction fee, it’s almost always cheaper than the "convenience" rate offered by the ATM.
Local Bank ATMs to Look For:
- Česká spořitelna (the big blue one)
- ČSOB
- Komerční banka (KB)
- Air Bank (usually has a very modern interface)
- Raiffeisenbank
These are "real" banks. Their fees are transparent, and their machines won't try to trick you with flashy screens as much as the independent ones do.
Understanding the "Mid-Market" Rate
To convert USD to Czech crown effectively, you need to know what the money is actually worth. Use an app like XE or just type "USD to CZK" into Google. That number you see? That’s the mid-market rate.
No exchange office will give you that exact number because they have to pay rent and staff. However, a "fair" office in Prague should be within 1-2% of that rate.

For example, if the rate is 23.50 CZK to $1, a good exchange office will give you around 23.10 or 23.20. If they are offering 20.00, walk away. There is a famous place called "Exchange" on the corner of Kaprova and Maiselova streets. It’s legendary among expats. They usually have the best rates in the city, and they don't do the "VIP rate" trick where you only get the good rate if you trade $1,000 or more.
A Quick Word on Credit Cards
Cards are great. Use your Visa or Mastercard for dinner, for your hotel, and for shopping at malls like Palladium. Most US cards now have zero foreign transaction fees.
But watch out for the "DCC" trap again. When the waiter brings the card terminal and it asks if you want to pay in USD or CZK, pick CZK.
I cannot stress this enough. If you pick USD, the Czech merchant's bank chooses the exchange rate. They will not be kind. They will pick a rate that favors them, often adding a 5% or 7% markup. Always pay in the local currency of the country you are standing in. It sounds counterintuitive to choose the currency you don't understand as well, but it’s the golden rule of international travel.
The 3-Hour Law You Need to Know
The Czech government actually stepped in a few years ago to stop the predatory exchange offices. There is now a law that allows you to cancel an exchange transaction within three hours, provided the amount was under 1,000 Euros (about $1,100).
If you realize you’ve been ripped off right after walking out the door, go back in. Show them the receipt. Tell them you want to cancel the transaction under the law. They might grumble, they might pretend they don't understand, but they are legally required to give you your dollars back.
This was a huge win for consumer rights in Prague, but many tourists have no idea it exists.
Practical Tips for Your Trip
Don't carry massive amounts of cash. Prague is generally very safe, but pickpockets love a tourist with a bulging wallet near the Charles Bridge.
- Carry a mix. Have about 1,000 to 2,000 CZK (roughly $45-$90) in your pocket for small things. Use your card for everything else.
- Check the bills. Czech banknotes are beautiful. They feature famous figures like Emmy Destinn and Tomáš Garrigue Masaryk. Make sure you aren't being handed old bills that are no longer in circulation. The Czech National Bank periodically retires older designs.
- Coins matter. The 50 CZK coin is large, bi-metallic, and actually worth about two dollars. Don't let them accumulate in your bag thinking they are just "pennies." They add up fast.
If you are planning to head out of Prague to places like Český Krumlov or the Pilsner Urquell brewery in Plzeň, cash becomes even more vital. The further you get from the capital, the less likely a small family-run penzion is to accept a flashy American Express card.
Final Steps for a Fair Exchange
When you are ready to convert USD to Czech crown, follow this mental checklist to ensure you aren't losing money.
First, check the current rate on your phone so you have a baseline. Second, look for a reputable bank ATM or a high-rated exchange office like the one on Kaprova street. Third, if you are at an exchange window, always ask, "How many crowns will I get for 100 dollars total?" Wait for them to show you the number on a calculator. Don't just look at the board.
Finally, if you use an ATM, always decline the conversion. Let your bank do the math.
Once you have your crowns, go grab a "Smažený sýr" (fried cheese) sandwich from a street cart. It’s the ultimate Czech comfort food, it costs about 100-120 CZK, and it’s the perfect way to celebrate your newfound currency expertise.
Your Action Plan:
- Download an offline currency converter so you don't need Wi-Fi to check rates.
- Contact your bank before you leave the US to ensure your card is active for international use and to check their foreign ATM fees.
- Locate a "real" bank ATM at the airport for your initial 500 CZK to get you to your hotel, rather than using the currency desks.
- Always carry a backup card kept in a separate place from your primary wallet, just in case.
