Thai Baht Currency Conversion Matrix
Compare 5 payment methods and find the cheapest FX to baht.
All 5 methods compared in one table.
What this solves
Five ways to convert to baht, five different effective rates. Cash at an airport counter loses 3–6% to spread + commission. ATM withdrawals charge a flat 220-baht foreign fee per transaction plus a 1.5–2% FX margin. Credit cards charge 0–1.5% FX margin. Travel cards (Wise, Revolut, Charles Schwab) usually win on FX margin but charge ATM fees.
How to read results
"Effective rate" is the implicit baht-per-unit-currency you actually receive. The headline market rate is the mid-rate; the difference between effective and market rate is your hidden cost. Travel cards that advertise "mid-market rate" can still lose 0.5–1% on round-trip conversion if your home currency isn't directly supported.
Limitations
- Bank-specific ATM fees vary. Thai banks charge 220 baht flat; your home bank may add another fee.
- Credit-card FX margins depend on issuer (Amex is typically 1.5%, Visa/MC 0.5–1%).
- Travel-card balance must be loaded in advance — they cannot convert at point of sale.
FAQ
Which method is cheapest?
For large purchases (hotels, tours), credit cards with no foreign-transaction-fee usually win. For daily spending, a travel card (Wise, Revolut) at a Thai ATM typically beats cash exchange. Cash exchange at airport kiosks is the most expensive.
Should I bring USD to exchange?
Yes, USD is widely accepted at Thai exchange counters (SuperRich, Vasu) and rates are best for USD. EUR and GBP work too but with slightly worse rates. AUD and smaller currencies often lose 2–3% in spread.
What is DCC and should I decline it?
DCC (Dynamic Currency Conversion) is when an ATM offers to charge you in your home currency instead of baht. The rate is typically 3–7% worse. Always decline DCC and choose to be charged in baht.
