Always decline conversion at a foreign ATM. Choose the local currency. The conversion offered by the machine is nearly always 5–10 percent worse than what your card network applies. On a $200 withdrawal, that's $10–$20 saved with one tap.

This page is written to solve a real travel-money decision quickly, then connect it to the supporting guides and kits that help the traveler act on it.
The screen that asks if you want to be charged in your home currency at a foreign ATM is the most common — and most expensive — single travel-money trap. It is presented as helpful. It is not.
The real cost of one wrong ATM withdrawal
You withdraw $200 abroad with the wrong card:
ATM operator fee: $5
FX markup (2.5%): $5
DCC home-currency trap (5%): $10
Total: about $20 on one withdrawal
With the right setup: $0–$1
What the DCC Prompt Looks Like
The exact wording varies by machine, but the choice is the same. The right answer is always: pay in local currency, decline the machine's conversion.
"Do you accept conversion at X.XX rate?"
"Pay in USD / Pay in [local currency]"
"Charge my home currency / Charge local"
"Locked rate: X.XX — accept or decline"
Why the Machine's Conversion Is Always Worse
When you let the ATM do the conversion, it uses a proprietary rate that includes a markup of typically 5–10 percent. When you decline, your card network (Visa or Mastercard) applies its near-interbank rate. The card network rate is almost always better.
Real Decline-Conversion Fee Math
One $200 withdrawal, two outcomes
Accept conversion: ~$10–$20 lost in DCC markup.
Decline conversion (choose local currency): $0 lost.
Time cost: 1 tap. Saved: equal to half a kit.
