You’ve just finished a misty morning walk across the Charles Bridge, the smell of trdelník is still clinging to your jacket, and you realize you have a pocket full of colorful banknotes. The Czech Republic is beautiful, but those koruny (CZK) won't buy you much once you land back in JFK or LAX. You need to convert Czech crowns to dollars, and honestly, how you do it matters more than you might think.
I’ve seen travelers lose nearly 20% of their money just by picking the wrong window at the airport. It's a classic trap. The math seems simple on a calculator, but the "real world" exchange rate is a moving target. As of mid-January 2026, the rate is hovering around 0.048 USD for 1 CZK. That means for every 1,000 Czech crowns, you’re looking at roughly $48. But wait. If you walk into a generic "Change" booth in Old Town Square, they might only hand you $35 and call it a day.
Why the Mid-Market Rate is Your Only Friend
Most people Google the exchange rate and assume that's what they'll get. That’s the mid-market rate—the "true" price banks use to trade with each other. Retail exchange offices almost never give you this. They take that rate and shave off a percentage for themselves. This is called "the spread."
If you want to convert Czech crowns to dollars without getting fleeced, you have to compare the offered rate against the live mid-market data from a source like the Czech National Bank (CNB) or a reliable live tracker. In Prague, the difference between a "tourist rate" and a "VIP rate" (often given for larger amounts or at reputable spots) can be massive.

Where to Actually Go in Prague
If you’re still in the city, don't just go anywhere.
- Exchange.cz (Kaprova street): This is basically the gold standard for locals and savvy expats. They have a blue storefront near Old Town Square and are famous for being honest.
- Štefánikova 203/23 (Smíchov): Often cited by experts like Janek Rubeš (the Honest Guide guy) as a place that won't rip you off.
- Avoid Euronet ATMs: You'll see these everywhere. They are bright, blue, and yellow. They are also notorious for aggressive "Dynamic Currency Conversion" (DCC) which offers you a guaranteed rate that is actually terrible.
Converting Your Cash Back in the States
Let’s say you already flew home and found 5,000 CZK tucked in your passport. Now you're in the US and need to convert Czech crowns to dollars. This is where it gets tricky. Most local US bank branches don't just keep Czech koruna in the drawer.
If you go to a major player like Bank of America or Chase, they might require you to be an account holder. Even then, they often have to "buy" the currency from you at a rate that covers their shipping and handling costs. For a few hundred crowns, it might not even be worth the gas to drive there.
Check the physical currency first. The Czech Republic recently phased out older banknotes with thin silver strips. If you have those, most US banks will refuse them entirely. You’d have to go to a Czech bank branch in person to exchange those old notes, which is a major headache if you're already back in Ohio.

Digital Alternatives: The Revolut and Wise Factor
Honestly, the best way to convert Czech crowns to dollars in 2026 isn't with paper money at all. If you have your funds in a Czech bank account (maybe you were working there or have a local friend), use a service like Wise or Revolut.
These apps use the mid-market rate. They charge a transparent fee—usually a fraction of a percent. For example, moving 20,000 CZK to a US bank account via Wise might cost you about 150 CZK in fees, whereas a traditional wire transfer could eat up 500 CZK plus a bad exchange rate.
- Open the app.
- Select CZK to USD.
- Check the live rate.
- Hit send.
It’s almost always cheaper than holding physical cash.

Common Pitfalls to Avoid
The biggest mistake? The "No Commission" sign. It's a total lie. If a booth says "0% Commission," it just means they've hidden their profit in a terrible exchange rate. Always ask: "How many dollars will I get in my hand for X crowns?" Do the math yourself.
Another weird one is the "Street Money Changer." People will approach you near the Astronomical Clock offering a "great rate." They will hand you a stack of notes that look right, but they’re often Belarusian Rubles or discontinued Hungarian Forint. Both are worthless in Prague. Never, ever exchange money on the sidewalk.
Actionable Next Steps
If you are sitting on Czech crowns right now, here is exactly what you should do to get the most value:
- Check the Date: Ensure your notes are the "new" versions with the wide 100, 200, or 500 CZK strips.
- Use the Airport as a Last Resort: Only exchange enough for a coffee. Wait until you hit a reputable city-center exchange or use a "Big Bank" ATM.
- Always Choose CZK on the Screen: If an ATM or card reader asks if you want to be charged in "USD (with conversion)" or "CZK (local currency)," always choose CZK. Your home bank's conversion rate is almost certainly better than the ATM's.
- Check Online First: Before walking into a physical office in the US, call ahead. Many branches need 24-48 hours' notice to process "exotic" currencies like the koruna.
Converting your money doesn't have to be a loss. By staying away from the shiny tourist booths and sticking to verified offices or digital transfers, you keep your hard-earned money where it belongs—in your own pocket.
