Currency Exchange Fee Calculator

Airport exchange booths can quietly take 10–15% of every dollar you convert. See exactly how much you're losing — and which method costs almost nothing.

Mid-market rate ≈ $1.0870 per EUR. Rates are approximate and for comparison only.

Converting $500 at an airport booth costs you approximately $50.00 in hidden fees (10%). Using Wise instead saves you $47.50 on this transaction.

Converting to Euro (EUR)

✈️Airport Exchange Booth

€414

you receive for $500

Worst option−$50.00 (10%)

Airport bureaux de change and hotel desks typically offer 8–12% worse than mid-market rate. The rate displayed never includes their spread.

🏦Bank Branch / High Street Bureau

€435

you receive for $500

Poor for small amounts−$32.50 (6.5%)

High-street banks and exchange shops typically offer 4–7% spread plus a flat commission. Better than airports but not by much.

💳Credit Card with Foreign Transaction Fee

€460

you receive for $500

Avoid if possible−$15.00 (3%)

Standard credit cards (most US and UK cards) charge a 3% foreign transaction fee on every purchase. You get mid-market rate minus 3%.

🏧Local ATM (home card, no DCC)

€460

you receive for $500

Decent for large withdrawals−$4.00 (0.8%)

Withdrawing cash at a local ATM using your home debit card gives mid-market rate. The flat ATM fee ($3–5) is the only cost — so take larger amounts less often.

💚Wise (formerly TransferWise)

€458

you receive for $500

Best for most travelers−$2.50 (0.5%)

Wise uses the real mid-market exchange rate and charges only ~0.5% conversion fee. Excellent for large purchases or sending money abroad.

5 exchange traps — and the truth

Each one sounds reasonable. None of them are.

The 3-step currency strategy

1

Get a no-fee travel card before you go

Wise, Revolut, Monzo (UK), Charles Schwab (US), or a travel credit card with no foreign transaction fee. This alone saves you 3–12% on every transaction.

2

Use your card for most purchases — always in local currency

Decline DCC every single time. Pay local currency. Your card's exchange rate is far better than any merchant conversion.

3

Withdraw cash strategically from local ATMs

Take $200–300 at a time from local ATMs (not airport ATMs) to cover vendors who don't take cards. Always decline their conversion offer.
