How to Handle Money When You Travel

The single biggest hidden cost on most international trips isn't food, lodging, or activities — it's the cumulative bleed from terrible exchange rates and foreign transaction fees. A few simple decisions before you leave can easily save 5–10% of your total trip budget.

Never exchange cash at the airport

Airport currency exchange counters offer some of the worst rates available anywhere — often 8–12% above the mid-market rate, sometimes more, and frequently with additional flat fees on top. They get away with it because they have a captive audience of arriving travelers who feel they need cash immediately. They almost always don't.

If you absolutely need a small amount of local cash on arrival, exchange $50–100 at your home bank before you leave (better rates than airports), or use an ATM in the airport's main concourse rather than the currency counter — ATM rates are typically much closer to the mid-market rate, even after withdrawal fees.

Use a card with no foreign transaction fees

Most credit cards charge 3% on every foreign purchase — this is usually buried in the cardholder agreement and never shown on the receipt. On a $5,000 trip, that's $150 in fees you'll never see itemized. Many travel-focused credit cards (Capital One Venture, Chase Sapphire Preferred, almost any Amex) have no foreign transaction fees. Check your wallet before you leave — if your daily card charges 3% abroad, it's worth applying for a no-fee card before your trip.

Watch for "dynamic currency conversion"

When you pay with a foreign card abroad, some merchants and ATMs ask if you'd like to be charged in your home currency instead of the local one — they'll show you the converted amount and a "convenient" exchange rate. Always decline this and pay in the local currency. Dynamic currency conversion uses an exchange rate set by the merchant's payment processor, typically 4–7% worse than your card's actual conversion rate. Always pay in euros in Paris, yen in Tokyo, baht in Bangkok — never in dollars.

Use ATMs, but pick the right ones

Bank-owned ATMs at your destination are usually the best way to get local cash — exchange rates are very close to mid-market, and many U.S. banks have global ATM networks that waive fees (Charles Schwab Bank's checking account famously refunds all ATM fees worldwide). Avoid standalone ATMs in tourist areas, hotel lobbies, and convenience stores — these often charge $5+ withdrawal fees and offer dynamic currency conversion.

Carry some cash, but not too much

Most countries are increasingly card-friendly, but cash is still essential for tipping, small vendors, taxis, public transit in some cities, and emergencies. A reasonable rule of thumb: bring enough cash for one to two days of basic spending (around $100 USD equivalent), then withdraw more from local ATMs as needed. Carrying large amounts of cash invites theft and gives you nothing in exchange — most international travelers spend the bulk of their trip budget on cards.
