Money Mistakes Most Global Travellers Make

You have researched the destination, booked the flights, packed the bags,  and then you land and quietly hemorrhage money in ways you never saw coming. It happens to first-timers and seasoned travellers alike. The difference is that experienced travellers learn to spot the traps before they fall into them.

This guide covers the most common travel money mistakes made by travellers worldwide, and exactly what to do instead.

‍

1. Exchanging currency at the airport

Airport currency exchange booths are among the most expensive places in the world to convert money. They rely on one thing: urgency. You have just landed, you need local cash, and you have no time to shop around.

The result is exchange rates that can be 10 to 15 percent worse than the mid-market rate, often with additional service fees on top. The same applies to exchange booths in hotel lobbies and busy tourist areas.

‍

2. Not notifying your bank before you travel

Banks and card providers monitor your spending for unusual activity. Charges in a foreign country,  especially if you have never transacted there before, can trigger an automatic fraud alert, resulting in your card being frozen at the worst possible moment.

‍

3. Paying in your home currency abroad 

This is one of the most widely misunderstood travel money traps. When paying by card at a foreign shop, restaurant, or ATM, you may be asked: "Would you like to pay in your home currency or local currency?"

Always choose local currency. The option to pay in your home currency is called Dynamic Currency Conversion (DCC), and it uses the merchant's exchange rate rather than your bank's,  which is almost always significantly worse. The convenience sounds appealing; the cost is not.

4. Relying on a single card or payment method

Cards get lost. Cards get swallowed by foreign ATMs. Cards get frozen. Arriving in a new country with a single card and no backup is a risk that can completely derail a trip.

What to do instead: Top up your Pesa wallet(s) with enough funds.  Carry a modest amount of local cash as a backup for situations where cards are not accepted, or a bank transfer might not be possible.

5. Using a card with high foreign transaction fees

Many standard bank cards charge a foreign transaction fee of 1.5 to 3 percent on every purchase made abroad. On a two-week trip with regular card spending, these fees add up quickly and often go unnoticed until you review your statement at home.

What to do instead: Before you travel, check whether your card charges foreign transaction fees. If it does, consider opening a dedicated travel card or account that waives these fees. Many digital banks and travel-focused financial products now offer fee-free international spending, which can save a meaningful amount over the course of a trip.

6. Moving around with more cash than you need

Carrying large amounts of cash is a security risk in any destination. Cash that is lost or stolen cannot be recovered, and walking around with a visibly full wallet makes you a target in busy tourist areas, public transport, and markets.

What to do instead: Withdraw enough cash for the day, not the entire trip. Use hotel safes or secure accommodation storage for any surplus. Split cash between different locations on your person,  a main wallet, and a secondary, hidden spot,  so that losing one does not mean losing everything.

‍

7. Failing to budget for hidden costs

Many travellers budget well for flights and accommodation but underestimate the ongoing costs that accumulate daily: local transport, meals, entrance fees, tips, visas on arrival, departure taxes, and those spontaneous purchases that are hard to say no to.

In many cultures, tipping is expected and effectively mandatory in service industries. In others, it is uncommon or even considered rude. Not knowing the local norm can leave you either underpaying or overpaying.

What to do instead: Research the true daily cost of your destination before you go, including tipping culture, common transport costs, and typical meal prices at different budget levels. Build a daily spending estimate and track against it using a budgeting app or a simple note on your phone. Always leave a buffer of 10 to 20 percent above your estimated total for unexpected expenses.

8. Not researching haggling culture

In many parts of the world, across Asia, Africa, the Middle East, and Latin America, the first price quoted to a tourist is rarely the final price. Vendors expect negotiation, and paying the asking price without question can mean significantly overpaying by local standards.

Conversely, aggressive or disrespectful haggling in a culture that values politeness can cause genuine offence.

‍

9. Ignoring atm fees

Foreign ATMs often charge their own fees on top of any fees from your home bank. Withdrawing small amounts frequently is one of the most expensive ways to access cash abroad, as each transaction incurs a fixed fee regardless of the amount withdrawn.

What to do instead: Withdraw larger amounts less frequently to minimise the number of transactions and therefore the total fees paid. Check in advance whether your card provider reimburses ATM fees, as some travel accounts do. Use ATMs that are attached to reputable banks rather than standalone machines in tourist areas, which are more likely to apply inflated rates.

‍

10. Not buying travel insurance

It is estimated that a significant share of international travellers depart without adequate travel insurance. Medical emergencies abroad can result in bills that run into the tens of thousands, and in some countries, hospitals require proof of insurance or upfront payment before providing treatment.

Beyond medical cover, travel insurance also protects against trip cancellations, lost or stolen baggage, flight delays, and emergency repatriation — risks that no traveller is immune to.

What to do instead: Purchase comprehensive travel insurance before every trip. Read the policy carefully, paying attention to what is excluded. If you travel frequently, an annual multi-trip policy is often more cost-effective than buying per trip.

‍

11. Overpacking and paying unnecessary baggage Fees

Low-cost and budget airlines in particular have made baggage fees a significant revenue stream. Many travellers book a cheap base fare only to find that checked luggage, cabin bag upgrades, and even seat selection push the total cost well above what a full-service airline would have charged.

Overpacking also limits your transport options. A heavy suitcase makes public transit harder and often pushes travellers toward more expensive taxis or rideshares.

What to do instead: Check the baggage policy in detail before booking and factor it into the true cost comparison. Pack light enough to manage public transport and avoid checked bag fees. If your trip involves multiple flights, weigh your bag before each departure — especially on the way home when souvenirs and purchases add up.

‍

12. Not keeping digital copies of important documents

Lost or stolen passports, insurance documents, and booking confirmations can cause serious disruption. Embassies and consulates can often issue emergency travel documents more quickly if you can provide a copy of the original passport.

What to do instead: Before departure, scan or photograph your passport, insurance policy, travel itinerary, and any visas. Store copies securely in a cloud service you can access from any device, and email copies to yourself and a trusted person at home.

Things to keep in mind when travelling internationally.

What is the cheapest way to access money abroad?

Using a fee-free international debit or travel card at a reputable local bank ATM is generally the most cost-effective method. Avoid airport exchange booths, hotel desks, and standalone ATMs in tourist areas.

Should I use cash or a card when travelling internationally?

Ideally both. Cards are convenient and offer competitive exchange rates, but cash remains essential in many destinations for small vendors, markets, taxis, and rural areas. Carry enough local cash for day-to-day needs and use a card for larger transactions where possible.

Is it better to exchange currency before travelling or at my destination?

It depends on the destination. For major currencies and well-serviced destinations, local ATMs often offer the best rates. For less common currencies or destinations with limited ATM access, exchanging a portion of the funds before departure through a reputable currency exchange service (not the airport) can be sensible.

How much travel money should I take?

Research your destination's daily cost of living and multiply by the number of days, then add a buffer of 15 to 20 percent. Factor in one-off costs like visas, tours, and souvenirs separately from daily spending.

What should I do if my card is lost or stolen abroad?

Contact your bank immediately to cancel the card and request an emergency replacement. This is why travelling with a backup card is essential. Your bank may also be able to arrange emergency access to cash in some circumstances.
