Before you leave or at least before you exchange too much money, plan ahead on what you’ll be doing and how much money you’ll need. Exchange on the low side of how much you think you’re going to use. This way, you won’t risk over-exchanging and wasting money on having to exchange the money back once you return. This will also help you incur the minimum number of fees, if the exchange fee with your chosen method is a one-time fee (such as at an ATM or bank). Look up the most current exchange rate before you exchange money using a service, especially if you’re using a currency exchange service specifically. Businesses that specialize in exchanging currency and some small businesses that exchange currency will both often give you an outdated exchange rate that works in their favor, so that they can make more money off of you. Download an app before you leave so that you can easily check the exchange rate on your phone. Just be careful to only leave data on when you’re actively checking the rate, so that you don’t go over on your data plan while you’re abroad. Don’t be afraid to find out what you can get at a different location. Banks may be less of an issue, although some banks might have less fees than others, but currency exchange businesses will definitely have very variable rates. This will also give you the added bonus of possibly being able to haggle with the business, since a small currency exchange will be more willing to fight for your business. If you are in an area where you have the option to pay in your own currency, do that. Usually, if a business allows this they will tell you or the price will be marked. Make sure you’re informed about the exchange rate before paying, however. You can expect a small markup, so that they can pay the exchange fees on their end, but it should only be small. This is most common in areas and countries where your currency is very highly valued or is used frequently. Most of the time, your best bet is to exchange your money in the country you travel to.
