You’re standing in the middle of Prague’s Old Town Square, the astronomical clock is about to chime, and you realize your wallet is full of colorful bills that look like Monopoly money. You need to convert Czech koruna to US dollars—or maybe you're doing the opposite—and suddenly, the stress of getting ripped off hits. Honestly, the world of currency exchange is kinda murky. You see a sign that says "0% Commission," but the rate they’re offering is so bad it’s basically a legal mugging.
In early 2026, the Czech koruna (CZK) has been hovering around a specific range against the greenback. As of mid-January 2026, the mid-market exchange rate is roughly $1 for 20.82 CZK, or 1 CZK for about $0.048. But here is the thing: you will almost never get that "mid-market" rate at a physical booth. That’s the "wholesale" price banks use. You’re likely looking at a spread that eats 2% to 10% of your cash if you aren't careful.
The Brutal Truth About "Zero Commission"
Most people see "Zero Commission" and breathe a sigh of relief. Don't. It's a classic trap. If a booth isn't charging a fee, they are making their money by widening the gap between the "buy" and "sell" rates.
Imagine the official rate is 21 CZK to the dollar. A "no commission" booth might offer you 18 CZK. You just lost 15% of your money without paying a single "fee." It’s basically a magic trick where your money disappears in plain sight.
If you are physically in Prague and need to convert Czech koruna to US dollars, head to Exchange.cz on Kaprova Street. It’s a local legend for a reason. They actually follow the market and offer a "VIP rate" for larger amounts that is surprisingly fair. Another solid bet is XChange Grossmann near Wenceslas Square. These places are the gold standard in a city that, unfortunately, still has some shady operators lurking in tourist traps.

Banks vs. Apps: Who Wins in 2026?
If you're sitting at home in the US or a Czech apartment trying to move larger sums, forget the physical booths. You’ve probably heard of Wise (formerly TransferWise) or Revolut. They’ve changed the game.
Traditional banks like Česká spořitelna or Komerční banka are safe, sure, but they usually charge a flat fee plus a hidden markup on the rate. For a 100,000 CZK transfer, a bank might cost you $50 more than a fintech app.
- Wise: They use the real mid-market rate and show you the fee upfront. It’s transparent.
- Revolut: Often the cheapest on weekdays, but be careful on weekends when they add a small markup because the markets are closed.
- Paysend: A newer player that has been gaining traction in 2025 and 2026 for fixed-fee transfers directly to cards.
The "best" way to convert Czech koruna to US dollars really depends on your speed requirements. If you need it in minutes, Revolut-to-Revolut is king. If you’re moving a house deposit, a specialist broker like Key Currency or CurrencyTransfer might actually save you more by giving you a dedicated human to talk to.
Why the Koruna Is Volatile Right Now
Why does the rate keep jumping? The Czech Republic is a massive export economy. When Germany’s economy sneezes, the koruna catches a cold. Throughout 2025, we saw the CZK strengthen as the Czech National Bank kept interest rates higher than the Fed in the US.
But things shift. If you are watching the charts, keep an eye on the Czech National Bank (ČNB) announcements. They are famously interventionist. If the koruna gets too strong and starts hurting Czech exporters (like Škoda), the ČNB might step in to weaken it. This makes timing your conversion a bit of a gamble.
Practical Steps to Get the Most Dollars
Stop using airport exchanges. Just don't do it. The rates at Václav Havel Airport are consistently some of the worst in Europe. If you absolutely need cash for a taxi, take out the bare minimum from an ATM—but watch out for the "Dynamic Currency Conversion" (DCC) prompt.
When an ATM asks, "Would you like to be charged in your home currency?" always say NO. Choose "Charge in local currency" (CZK). If you let the ATM do the conversion, they’ll use their own terrible rate. Let your own bank at home handle the math; it’s almost always cheaper.
For those sending money back to the States, here is the move:
- Check the mid-market rate on a site like XE.com so you have a baseline.
- Compare Wise vs. Revolut for that specific day.
- Avoid the weekend. Rates are locked and usually padded with a "safety margin" by providers.
- Keep your receipt. In the Czech Republic, you actually have a legal right to cancel a currency exchange within 3 hours if you realize you got a bad deal (for amounts up to 1,000 EUR).
The koruna isn't a "major" currency like the Euro or Yen, which means it can be more expensive to trade. Being proactive saves you enough for a few extra rounds of Pilsner or a nice dinner in Manhattan.

To get started, download the Wise or Revolut app and verify your ID before you actually need to move the money. Verification can take 24 hours, and you don't want to be stuck waiting when the exchange rate is perfect. Check the current ČNB fixing rate on their official website to see exactly where the "official" price stands before you commit to any transaction.
