So, you’re heading to Warsaw or maybe scouting out a flat in Kraków. You’ve got a wallet full of Greenbacks and a head full of questions about how to actually spend them without getting fleeced. Honestly, the world of currency exchange is a bit of a minefield if you don't know the lingo.
Most people just walk up to the first booth they see at the airport. Big mistake.
Converting your hard-earned cash shouldn't feel like a shakedown, yet travelers regularly lose 10% to 15% of their money to "convenience" fees and "zero commission" traps. If you want to convert dollars to polish zloty the smart way, you need to understand how the system actually works in 2026.
The "Kantor" Culture: Poland’s Secret Weapon
In Poland, you don't go to a "currency exchange." You go to a Kantor. These are small, independent booths that have been the backbone of Polish money-changing since the fall of communism. They are everywhere—malls, train stations, and tucked away on side streets.
But here’s the thing: not all Kantors are created equal.
If you see a Kantor in the middle of Warsaw’s Old Town with neon signs screaming "No Commission," keep walking. You’ll get a terrible rate. They aren't lying about the commission; they just bake a massive profit into the "spread"—the difference between the buy and sell price.

Pro Tip: Look for Kantors located near business districts or inside shopping malls like Złote Tarasy in Warsaw. They usually have tighter spreads because they compete for local business, not just one-off tourists. As of mid-January 2026, the mid-market rate is sitting around $1 to 3.64 PLN. If a Kantor offers you 3.10, they’re basically taking you for a very expensive lunch.
The ATM Trap: Why "Dynamic Currency Conversion" Is a Scam
You’re at a bankomat (that’s Polish for ATM). You stick your US debit card in. The screen asks a very polite question: "Would you like to be charged in USD or PLN?"
It sounds helpful. It’s a trap.
This is called Dynamic Currency Conversion (DCC). If you choose USD, the ATM owner gets to choose the exchange rate. Predictably, they choose a rate that is garbage for you. Always, always, always choose PLN.
When you choose the local currency, your home bank in the States handles the conversion. Even with a small foreign transaction fee, your bank’s rate will almost certainly beat the ATM’s "guaranteed" rate.

Digital Disruptors: Wise vs. Revolut in 2026
If you’re still carrying around a wad of paper hundreds, you’re living in 2010. Most savvy travelers now use "neobanks."
I personally use Wise (formerly TransferWise) or Revolut. Here is why:
- The Real Rate: They use the "mid-market" rate—the same one you see on Google.
- Instant Conversion: You can move $500 into a PLN sub-account in three seconds while standing in line at a pierogarnia.
- Apple/Google Pay: Poland is incredibly digital. I’ve gone weeks in Warsaw without touching a physical coin. You can tap your phone for everything from a tram ticket to a head of cabbage at a street market.
Wait, do you actually need cash? Sort of. While cards are king, you’ll want a few zlotys for:
- Tipping your tour guide.
- Using a public restroom (usually costs 2-5 PLN).
- Buying a souvenir from a grandma on a rural roadside.
The "Weekend Markup" and Other Weirdness
Here is a nuance most guides miss: Revolut charges a markup on weekends. Since the global currency markets are closed, they add a small percentage (usually around 1%) to protect themselves against price swings.
If you know you’re going to be partying in Kazimierz on a Saturday night, convert your dollars to polish zloty on Friday morning. It’s a tiny optimization, but over a two-week trip, those single percentages add up to a few extra rounds of Polish craft beer.

Can You Just Use Dollars?
Nope.
In some countries, the US Dollar is a parallel currency. In Poland, it’s just fancy paper. You cannot pay for your hotel or your dinner with USD. Some high-end hotels might "accept" them as a courtesy, but they will give you a rate so bad it borders on a crime.
Actionable Steps for Your Money
Don't overthink it, but don't be lazy either. Here is exactly what I would do if I were landing in Poland tomorrow:
- Before you leave: Download the Revolut or Wise app and move some money there. It takes a few days to verify your ID, so don't wait until you're at the gate.
- At the airport: Ignore the exchange booths. If you absolutely need cash, find a bank-owned ATM (look for names like PKO BP, Pekao, or ING) and withdraw 200 PLN. Remember: Choose PLN, not USD on the screen.
- In the city: Use your phone or card for 95% of transactions.
- The "Big" Swap: If you have a lot of physical cash, go to a Kantor on a street like Świętokrzyska in Warsaw. Check the rate on your phone first. If they’re within 0.05 of the Google rate, you’re doing great.
Poland is surprisingly affordable compared to Western Europe, but that’s no reason to give away your money to a middleman. Stick to the local currency, keep your eyes open for the DCC trap, and you’ll have plenty of zlotys left over for an extra plate of gołąbki.
To stay ahead of the game, check the current interbank rate on a site like XE.com or the Mastercard Currency Converter right before you make a big purchase. This gives you a baseline so you know if a merchant's "deal" is actually a dud.
