Currency Exchange Fees: How They Work & How to Avoid Them
The exchange rate you see on Google is not the rate you get. Between markups, ATM fees, and one sneaky terminal trick, travelers routinely overpay 3–8% on every foreign purchase. Here's where the money goes — and how to keep it.
Key takeaways
- The rate on Google is not the rate you get: travelers routinely overpay 3–8% per foreign purchase.
- The guide ranks payment methods from cheapest to most expensive.
- Never choose “pay in your home currency” at a terminal — that conversion is the priciest option.
- Five rules for cheap travel money, plus how much cash you actually need.
The markup: the fee you never see
Every currency exchange builds in a margin between the mid-market rate (the "real" rate) and the rate they offer you. A 3% markup on $2,000 of trip spending costs $60 — with no receipt line showing it. Airport kiosks and hotel desks often mark up 8–12%; they're the worst deal in travel money.
Cheapest to most expensive: how to pay abroad
| Method | Typical total cost | Notes |
|---|---|---|
| No-foreign-fee credit card | ~0–1% | Best default; Visa/Mastercard wholesale rate |
| Low-fee debit at local ATM | ~1–2% | Withdraw larger sums, fewer times |
| Prepaid travel cards (Wise etc.) | ~0.5–2% | Good for budgeting in the local currency |
| Your bank's foreign ATM | ~3–5% | $5 flat fee + 3% conversion adds up fast |
| Airport/hotel exchange | ~8–12% | Only for emergencies |
Five rules for cheap travel money
- Get a no-foreign-transaction-fee card before you go. The 3% fee most cards charge applies to every purchase abroad.
- Pay in local currency. Every time. ATMs and terminals will ask — decline the "convenience" conversion.
- Use ATMs, not exchange counters. Withdraw local cash on arrival; take out larger amounts less often to dilute flat fees.
- Warn your bank (or check the app) so a foreign transaction doesn't trigger a fraud block.
- Carry two cards from different networks. If one is lost, blocked, or not accepted, you're not stranded.
How much cash do you actually need?
Less every year. In most of Europe and East Asia, cards work essentially everywhere — transit, restaurants, even street markets. Carry local cash for tips, tiny vendors, and rural areas: the equivalent of $100–200 withdrawn from an ATM on arrival covers most trips.

Open the Currency ConverterFrequently asked questions
Should I exchange money before my trip?
Usually no — you'll get a worse rate than a no-fee card or local ATM abroad. Just land with a card that doesn't charge foreign fees.
Is it better to pay in local currency or USD?
Local currency, always. "Pay in USD" is dynamic currency conversion at a marked-up rate.
How do I avoid ATM fees abroad?
Use a bank account that reimburses foreign ATM fees (several online banks do), and withdraw larger amounts less frequently.
Are travel money cards worth it?
Services like Wise offer near-mid-market rates and are great for holding foreign currency — a solid backup to a no-fee credit card.
Does Google show the real exchange rate?
Google shows the mid-market rate — what banks trade at. You'll never get exactly that as a consumer; the gap is the markup.
