Kos Currency: Euros, ATMs and Money Tips

Kos uses the Euro, so if you're travelling from another eurozone country you can step off the ferry or plane without giving currency a second thought. For British, Scandinavian, and other non-euro visitors, a small amount of preparation goes a long way. Kos is one of the most popular Greek islands in the Dodecanese, drawing hundreds of thousands of British and Scandinavian tourists every summer, and the island's infrastructure is well set up for foreign visitors. Understanding how money in Kos works will save you from unexpected fees and the mild panic of being cashless at a beachside taverna.

Using Euros in Kos

The currency in Kos is the Euro (EUR, €). Greece has been part of the eurozone since 2002, and the Euro is the only official currency accepted across the island. You will not be able to pay with British pounds, Swedish kronor, Danish krone, or any other foreign currency at shops, restaurants, or transport services. Some tourist-facing businesses may quote prices in pounds or other currencies as a courtesy, but payment will always be taken in euros.

If you are travelling from the UK, the exchange rate fluctuates but has generally sat in the range of 1.10–1.20 EUR per GBP in recent years. Check a live rate before you travel so you have a realistic sense of what things cost. For Scandinavian visitors, the euro is well understood and widely used across the region, so you will find the island straightforward to navigate financially.

Cash vs Cards in Kos

Cards are widely accepted in Kos, particularly at hotels, larger restaurants, supermarkets, and established tourist shops. Visa and Mastercard are standard. American Express is hit and miss -- do not rely on it.

That said, cash still matters here. Smaller beach bars, street food vendors, local bakeries, and village tavernas away from the main tourist strips often prefer or require cash. Tipping -- which is appreciated but not obligatory in Greece -- is also almost always done in cash. Leaving a few euros on the table after a meal is the norm.

Local buses operated by KTEL are cash only. If you plan to use public transport to get around the island -- from Kos Town to Tigaki, Mastichari, or Kefalos -- make sure you have coins and small notes. The same applies to some beach sunbed rentals and smaller water sports operators.

A practical rule of thumb: carry 30–50 EUR in cash at all times during your stay. It covers buses, tips, and those small roadside purchases where a card machine is not available.

ATMs and Banks in Kos

ATMs are readily available in the main tourist areas. You will find multiple cash machines in Kos Town, which has the highest concentration, as well as in Kardamena, Tigaki, and Kefalos. In smaller villages and remote beach areas, ATMs are rare or non-existent, so withdraw before you venture out.

Greek ATMs are operated by banks including Piraeus Bank, Alpha Bank, Eurobank, and the National Bank of Greece. Most machines accept foreign debit and credit cards on the Visa, Mastercard, and Maestro networks.

Foreign card fees are worth understanding before you queue up. Greek ATMs typically charge a fixed withdrawal fee of around 2.60 EUR per transaction, regardless of how much you take out. Your own bank may also charge a foreign transaction fee on top of that. To minimise the impact, withdraw larger amounts less frequently rather than making small withdrawals every day. Taking out 150–200 EUR at a time is more economical than taking out 40 EUR four times.

Always choose to be charged in euros rather than your home currency when the ATM offers you a choice -- this is called Dynamic Currency Conversion, and the rate offered by the ATM is almost always worse than your own bank's rate.

Currency Exchange in Kos

If you arrive with non-euro currency and want to exchange it, there are a handful of currency exchange offices in Kos Town. They are convenient but their rates and commission structures vary. Banks generally offer more competitive rates than standalone exchange bureaus, though bank opening hours are limited (typically 08:00–14:30, Monday to Friday).

The most straightforward approach for most visitors is to arrive with euros already in hand, or to use an ATM on arrival. If you are travelling from the UK, exchanging at a reputable exchange service before you leave (such as the Post Office or a specialist travel money service) will often get you a better rate than exchanging on the island.

For regular travellers, a Wise or Revolut card is worth considering. Both offer near-interbank exchange rates with low fees, and they work at Greek ATMs. Revolut in particular has become popular with frequent Greek island visitors. Just be aware that Revolut's free plan has monthly ATM withdrawal limits before fees kick in.

Avoid exchanging money at hotels. The convenience comes at a significant cost -- hotel exchange rates are typically the worst available.

Tips for Managing Money in Kos

• Bring euros from home if possible. Exchanging before you travel usually gives you a better rate than changing money on the island.
• Withdraw larger amounts to reduce ATM fees. At 2.60 EUR per transaction, frequent small withdrawals add up quickly.
• Always decline Dynamic Currency Conversion. When an ATM or card machine offers to charge you in your home currency, say no. Pay in euros and let your bank handle the conversion.
• Keep small notes and coins for buses and tips. KTEL buses are cash only, and tips are always appreciated in cash.
• Tell your bank you are travelling. Some banks still block foreign transactions as a fraud precaution. A quick call or app notification before you leave avoids your card being declined.
• Consider a Wise or Revolut card if you travel frequently. The savings on exchange rates and fees over a two-week holiday can be meaningful.

Money in Kos FAQ

What currency does Kos use?

Kos uses the Euro (€). Greece is a member of the eurozone, and the Euro has been the official currency since 2002. No other currency is accepted for payment on the island.

Can you pay by card in Kos?

Yes, cards are accepted at most hotels, restaurants, and larger shops in tourist areas. However, smaller establishments -- village tavernas, beach bars, local markets, and public transport -- often require cash. It is worth carrying some euros in cash even if you primarily use a card.

Are there ATMs in Kos?

Yes. ATMs are available in Kos Town, Kardamena, Tigaki, and Kefalos. They accept Visa, Mastercard, and Maestro cards. A withdrawal fee of approximately 2.60 EUR per transaction applies to foreign cards. Withdraw larger amounts to reduce the per-transaction cost.

Is Kos expensive?

Kos sits roughly in the middle of the range for Greek islands. It is cheaper than Mykonos or Santorini, but not as budget-friendly as some lesser-known destinations. A sit-down meal in a local taverna might cost 12–18 EUR per person including a drink. Tourist-facing restaurants in the main resorts charge more. Supermarkets and local bakeries are good value for self-catering or snacks.

Do I need to exchange money before visiting Kos?

If you are already in the eurozone, no. If you are travelling from outside the eurozone -- particularly from the UK or Scandinavia -- it is sensible to arrive with at least some euros. Exchange before you travel for a better rate, or plan to use an ATM shortly after arrival. Do not rely on exchanging money at the airport or at your hotel, where rates are least favourable.
