Currency and exchange: timing and tactics that actually save money

A few bad exchange decisions can cost you 5–10% of your entire trip — money that could be weeks of travel. Most of it is avoidable.

The quiet tax on your travel budget

Currency isn't glamorous, but a few bad exchange decisions can cost you 5–10% of your entire trip — money that could be weeks of travel. The good news: most of it is avoidable.

The rules that hold up

  • Never change money at the airport. The worst rates, every time. Change a tiny amount to land, then use ATMs or local exchanges.
  • Use a low-fee card. Travel cards and good debit accounts refund ATM fees and use the mid-market rate. A 3% foreign-transaction card is a slow leak.
  • Pull local cash, in bigger pulls. A flat ATM fee hurts more on a small withdrawal. Take out what you'll spend in a week, not a day.
  • Carry a backup. Cards get eaten. Keep a second card and a little USD cash in a separate place.

Timing matters more than you think
