Straight answer first. The five money mistakes in Poland that cost tourists the most: paying in euros, accepting the ATM’s “conversion offer”, exchanging cash at the airport, paying tourist-square prices, and traveling either cash-only or card-only. Fix those five and Poland becomes what it actually is - one of the best-value countries in Europe, where a dollar buys you about 4 złoty and a full lunch costs less than an airport sandwich back home.
I’ve spent 30 years here. None of this is theory - I watch these mistakes happen every single day, usually within 100 meters of a landmark.
In a hurry? The five mistakes, one line each:
- Paying in euros - the “rate” is invented by whoever’s holding your change.
- Pressing “accept conversion” at the ATM - you just paid extra for nothing.
- The airport kantor - the worst exchange rate you’ll see all trip, guaranteed.
- Eating and shopping on the main square - two to three times the price, every city.
- Cash-only or card-only - Poland needs a mix, heavier on the card.
Now the details, because the details are where your money is.
Mistake 1: paying in euros
Poland is in the EU but not in the eurozone. Our currency is the złoty (PLN), and it’s the only money that actually works here.
Some tourist-facing places will “helpfully” accept euros in cash. The catch is the rate: the price is set in złoty, and whoever is behind the till converts it at a rate of their choosing - typically 10 percent or more worse than the real one. On a single coffee you won’t notice. Across a week of meals, tickets and souvenirs, it adds up to real money. You won’t get a better deal by paying in euros or dollars anywhere in Poland. Not once. It’s a convenience fee where the convenience is also theirs.
Make sure your card has a good conversion rate, and pay in złoty. If you remember nothing else from this article, remember that one phrase.
Mistake 2: the ATM “conversion” button (DCC)
This one has a boring official name - dynamic currency conversion - and it’s the single most efficient money-losing button in Poland.
At some point an ATM in Poland will ask: “Would you like to be charged in your home currency?” It sounds helpful. It is not. Say yes, and the ATM - not your bank - picks the exchange rate, and it picks one that’s usually several percent worse, sometimes past ten. On a 500 zł withdrawal, that’s roughly a nice dinner handed to a machine. Card terminals in shops and restaurants play the same game with the same question.
Always choose to be charged in złoty (PLN) - at every ATM, every card terminal, every time. Your own bank will do the conversion at a far better rate.
One more layer: not all ATMs are equal. Bank-owned machines (attached to an actual bank branch) usually charge little or nothing to withdraw. The freestanding ones parked in tourist spots - the Euronet-style machines glowing near every attraction - tend to add their own fees, suggest suspiciously small withdrawal amounts, and push the conversion button hardest.
Mistake 3: the airport kantor
A kantor is a currency exchange office. Most Polish kantors are honest, competitive businesses - locals use them all the time. The airport kantor is a different animal: it exists because you’ve just landed, you’re tired, and you don’t yet know what a złoty should cost (and you most probably don’t need cash yet). That’s the whole business model. It’s the classic currency exchange mistake, and it’s completely avoidable.
The rule scales to train stations and anywhere with wheeled suitcases: the closer the exchange board is to a departures screen, the worse the number on it.
Mistake 4: paying tourist-square prices
This mistake is pure geography, not a scam. Restaurants, cafés and shops on the main squares charge two to three times more than the same quality ten minutes away. That’s true in Kraków, Warsaw, Gdańsk, Wrocław, Zakopane - everywhere. A plate of pierogi that costs 10-20 zł in a bar mleczny (milk bar) becomes 45+ zł with a view of the square.
I’m not telling you to avoid the squares - have your coffee there, it’s a beautiful view and a fair trade. Just don’t do your eating, drinking and souvenir shopping at landmark rents.
The one-line version: walk ten minutes, eat where the queue speaks Polish, and your food budget roughly doubles in value.
Mistake 5: going cash-only or card-only
Tourists tend to pick a side. Both sides are wrong.
Card-only almost works - Poland is one of the most card-friendly countries in Europe. We tap our phones at bakeries and on buses. But “almost” bites you exactly when you don’t want it to: some market stands, some public toilets (yes, really), the occasional mountain hut.
Cash-only is worse. You’ll be carrying too much of it (see Mistakes 2 and 3 for how you got it), you lose card fraud protection, and you’ll spend your trip hunting kantors instead of castles.
The most useful of all Poland money tips: card as default, plus 100-200 zł in cash as backup, refreshed from a bank ATM when it runs low. Keep a few 10s and 20s - the 200 zł note from the ATM is technically money, but try buying an obwarzanek (under 5 zł) with it and watch the seller’s face.
While we’re here - card fraud in shops or restaurants is not a thing you need to worry about in Poland. The payment scams that do exist target nightlife, strip clubs especially.
Poland money tips: quick FAQ
Should I bring euros to Poland?
No - bring your card. Poland uses the złoty (PLN), and euros are only accepted at bad, made-up rates in tourist spots. If you want cash in hand, withdraw złoty from a bank ATM after landing rather than bringing euros to exchange.
Do ATMs in Poland rip you off?
Bank-owned ATMs don’t - most charge little or nothing. The freestanding ATMs in tourist areas add their own fees and push dynamic currency conversion.
Cash or card in Poland?
Card for 95% of it - Poland is extremely card-friendly, and contactless works nearly everywhere. Keep 100-200 zł in cash for market stalls, public toilets and remote areas. Both extremes (cash-only, card-only) will cost you at some point.
Where should I NOT exchange money in Poland?
Airports and train stations - their kantors have the worst rates in the country, sometimes 10% or more off the real rate. Exchange at city-center kantors after checking the mid-market rate on your phone, or skip cash exchange entirely and use bank ATMs.
Do you tip in Poland?
Around 10% in restaurants for good table service - appreciated, not mandatory. Cafés and bars: round up if you feel like it.
The local bottom line
Add it up. Euros at a made-up rate, a conversion button, an airport kantor, a week of square prices - a couple can quietly burn a few hundred złoty on nothing. Not on pierogi, not on castles, not on a museum ticket. On nothing.
And the frustrating part? The money mistakes in Poland are all solved by one boring sentence: pay by card, in złoty, away from the landmarks, with a little cash for backup. That’s it. That’s the whole local wisdom, 30 years of it.
