How to save money with currency exchange (my tips and tricks)

Tips for Currency Exchange

I've travelled to enough countries, and changed enough currencies, to say this honestly: almost every time, I walked away feeling like I'd been quietly ripped off somewhere along the way.

Most travel money advice doesn't help with that. It's either sponsored by whatever card it's pushing, or stuck comparing the same three options that were current a decade ago.

The real picture has genuinely changed since then, and pretending otherwise costs you money.

Here's an honest, current comparison of exchanging travel money, and what I'd actually use myself.

Credit cards

A standard credit card is probably the easiest option because you're already carrying one. The problem is that the card you use every day at home may not be the best one to take overseas.

Foreign transaction fees are the big one to watch. Even a small percentage added to every purchase can add up quickly over two weeks of hotels, meals, transport, and sightseeing.

Check these three things before you fly

  • Foreign transaction fees: Some credit cards charge a percentage every time you make a purchase in another currency. Look for a card with no foreign transaction fee if you plan to use it regularly overseas.
  • ATM and cash advance fees: Withdrawing cash using a credit card can trigger additional fees and interest, so check the terms before using one at an overseas ATM.
  • Points and rewards: If your card earns frequent flyer points or other rewards on overseas purchases, factor that into the comparison too. Just don't let the points distract you from higher fees.

I've been caught out by this myself. I once travelled with a card I thought was fee-free, only to discover a smaller charge buried in the terms that I'd never noticed on my domestic statements.

  • My rule now:

I check the actual fee schedule before travelling rather than assuming the card that's good at home will also be good overseas.


Bank travel money cards

Bank travel money cards let you load foreign currency before you leave, usually locking in the exchange rate at the time you convert.

They were once one of the obvious alternatives to travelling with cash, but newer multi-currency cards have made the choice less straightforward.

Where they still work well

  • You can lock in your exchange rate. If you're happy with the current rate, you know exactly how much foreign currency you have available before you travel.
  • They're separate from your everyday bank account. I like the added separation when travelling, particularly if a card is lost or compromised.
  • Spending is easy to track. Preloading a set amount can also help if you're trying to stick to a travel budget.

What I'd check first

  • The exchange rate margin. A card can advertise low or no transaction fees while giving you a less competitive exchange rate.
  • Loading and withdrawal fees. Check what it costs to add money, withdraw cash, or use currencies you haven't preloaded.
  • How it compares with newer alternatives. This is the big one for me. Traditional bank travel cards made much more sense before modern multi-currency accounts became widely available.

Modern multi-currency cards

Multi-currency cards are the biggest change I've seen in travel money since I first started writing about this topic.

Providers such as Wise and Revolut allow you to manage multiple currencies through one account and spend overseas using a linked card. For most travellers, this is now one of the first options I'd compare before reaching for a traditional travel money card.

How they work

The basic process is simple:

  1. 1
    Add money to your account in your country’s format.
  2. 2
    Convert it into another currency through the app, or let the provider handle the conversion when you spend, depending on the service and your setup.
  3. 3
    See the rate and applicable fees before confirming a conversion.
  4. 4
    Spend with the linked card anywhere that supports the card network you're using.

That transparency is the part I find most useful. Instead of looking only at a headline like "no transaction fees," you can see what your dollars are actually converting into and compare your options.

Why I'd consider one for travel

  • Multiple currencies live in one place. That's particularly useful if you're visiting several countries on the same trip.
  • You can convert money from your phone. There's no need to visit an exchange counter every time you need another currency.
  • Fees and rates are easier to compare. You can see the details of a conversion before committing rather than judging an option by its advertised fees alone.
  • You don't have to carry your entire travel budget in cash. I still take some local currency, but I no longer want a wallet full of it.

The catch: check the ATM rules

Don't assume every transaction will be cheap simply because you're using a multi-currency card. ATM withdrawal allowances, conversion fees, weekend pricing, and other charges can vary by provider, account type, currency, and how you use the card.

  • My Travel Tip:

Set everything up before you leave and make a small test transaction at home. I'd much rather discover a card, PIN, or app isn't working while I'm still at home than when I'm standing at an ATM overseas.


Cash

I still take cash on almost every trip, but these days I treat it as a backup rather than my main way of paying.

Plenty of situations still make life easier with local currency, especially once you get away from major hotels, restaurants, and tourist attractions.

When I still reach for cash

  • Markets and street food: Small vendors don't always accept cards, and even when they do, cash can be quicker and simpler.
  • Local transport: Taxis, buses, ticket machines, and other forms of transport can still require cash in some destinations.
  • Smaller towns and rural areas: Card acceptance can become less reliable once you move away from major cities.
  • Emergencies: A payment terminal goes down, your bank blocks a transaction, or your phone dies. A small amount of cash gives you another way to pay when technology doesn't cooperate.

If I need to exchange money, I check the current rate on my phone first, so I have a rough idea of what I should be getting.

In Australia, I'll compare several exchange providers rather than automatically using the most convenient one. Overseas, I stick to established, licensed exchange counters and avoid anywhere advertising a rate that looks suspiciously good.

  • My approach:

I carry enough local currency to get me through a few basic expenses, but not enough that losing my wallet would derail the trip.


Cash hasn't disappeared from my travel routine. I just find myself needing much less of it than I used to.


Bringing money home

One tip that's genuinely served me well over the years: if you land home with leftover foreign cash, don't lose money converting it back at an airport kiosk. The rates there are consistently poor.

Instead, if you know someone heading to that country soon, trade it directly with them at a fair mid-market rate. Everyone comes out ahead compared to what either of you would get exchanging through a kiosk.

It's a small thing, but it's saved me more money over the years than most of the bigger decisions on this list. Worth remembering the next time you land home with a pocket full of coins and notes you're not sure what to do with.


What about travellers cheques?

Travellers cheques are essentially obsolete for the vast majority of travellers now. Most banks have stopped issuing them, and few places still accept them. Unless you have a specific reason to use them, they're not worth factoring into a modern travel money plan.


Save money on more than just the exchange rate

The right method genuinely depends on the trip and the traveller, a mix of a fee-free card, a multi-currency account, and a modest amount of cash covers most situations well.

None of this needs to be complicated, and it doesn't need a specific product pushed on you to get right. It just needs a few minutes of setup before you leave, rather than sorting it out at the airport with whatever's already in your wallet.

Avoiding unnecessary fees really comes down to a bit of planning before you leave, rather than sorting it out at the airport on the way out.

If working out the right setup for your specific trip feels like one more thing to research, that's exactly the kind of avoidable cost our personalised travel planning service helps you sidestep.

We fold this into the planning conversation rather than leaving you to figure it out at the last minute.


Frequently asked questions

Is it better to exchange money before you travel or after you arrive?

Generally after you arrive or via a multi-currency card, since exchange counters at your home airport typically offer the worst rates available.

How much cash should you carry when travelling overseas?

You should carry enough to cover a day or two as a backup, rather than your full trip budget. Most spending is safer and more convenient on a card these days.

Do multi-currency cards work everywhere?

Mostly, though not universally. They work anywhere card payments are accepted, but very cash-reliant destinations or situations still benefit from carrying some local currency.

Is it safe to carry large amounts of cash while travelling?

No, it's generally best avoided. Carrying only what you need for a day or two reduces the impact if cash is lost or stolen.

Can you still use traveller's cheques?

Technically in some places, though it's increasingly difficult. Most banks have stopped issuing them and few merchants still accept them, so they're not a practical option for most trips.
