Travel costs money. That part is obvious. What is less obvious is how much of that money never actually reaches the thing you were paying for. It gets skimmed off at cash machines, at card terminals, at exchange counters, and in the quiet gap between the rate you see online and the rate you actually get.
Nobody hands you a receipt for this. The charges are small, scattered and easy to shrug off in the moment. Add them up over months of travel, though, and you are looking at real money. Flights. Nights in hotels. Weeks of extra time on the road.
Over the years I have built a system that keeps those losses close to zero. It is not clever and it is not complicated. It is mostly about knowing where the leaks are and refusing to pay for things that should be free.
Where the Money Actually Disappears
Before you can fix the problem, you have to be able to name it. There are four main ways travellers lose money, and most people are hit by all four on the same trip without noticing.
The foreign transaction fee
This is the flat percentage your card issuer adds every time you spend in a currency that is not your own. It usually sits somewhere between 1% and 3%. It applies whether you are buying a coffee or paying for a week of accommodation.
Three percent sounds like nothing. On a £6,000 year of travel spending, it is £180 you handed over for no service whatsoever.
The cash machine double-charge
Withdrawing cash abroad often triggers two separate fees. Your own bank charges you for using a machine outside its network. Then the machine’s operator charges you a second time, usually a fixed amount that hurts most on small withdrawals.
Take out the equivalent of £30 and pay £8 in combined fees, and you have lost more than a quarter of that money before you have spent a penny of it.
Dynamic currency conversion
This is the one that catches almost everybody. The card terminal asks whether you would like to be charged in your home currency instead of the local one. It looks like a courtesy. It is not.
Saying yes hands the conversion to the merchant’s payment processor, which sets its own rate and keeps the margin. The US Consumer Financial Protection Bureau and consumer groups across Europe have flagged this practice repeatedly, and the advice never changes: always choose the local currency. Always.
The exchange rate itself
Airport bureaux and hotel desks quote a rate that is nowhere near the real one. The gap is the profit. You can check what the genuine mid-market rate looks like on a tool like Visa’s exchange rate calculator before you agree to anything, and it takes about fifteen seconds.
Why Online Banking Changed the Maths
For a long time, the honest answer to “how do I avoid these fees?” was that you mostly could not. High street banks had no real competition and no reason to drop charges that customers barely noticed. Travellers just absorbed it.
That changed when banking moved onto phones. Providers running without branch networks carry a fraction of the overhead, and a lot of them passed that saving on in the form of no foreign transaction fees, fee-free cash withdrawals up to a monthly cap, and rates that sit far closer to the mid-market number. Because online only banks are built around an app rather than a counter, they also tend to do the practical things well — instant spending notifications, the ability to freeze a card the second it goes missing, and transfers you can move at two in the morning from a bus station in the middle of nowhere.
The traditional banks have responded, slowly, with their own travel-friendly accounts. Competition helped everyone. But the baseline expectation shifted, and it is now entirely reasonable to refuse to pay a percentage simply for spending money in another country.
A word of caution. Check what protection your deposits carry before you commit, whether that is FDIC coverage in the US or the equivalent scheme where you live. Convenience is not a substitute for security.
My Actual Setup
I do not use one account. I use several, and each one has a job.
A main account for income and bills. Nothing exotic. It holds the money I have already committed to rent, insurance and standing costs. I do not travel with the card for it, and it never touches a foreign cash machine.
A travel account for daily spending. This is the one that funds the trip. I move a set amount into it at the start of each month, which means my day-to-day card cannot expose everything I own. It is also a natural budget: when it runs low, I have overspent, and I do not need a spreadsheet to tell me so.
A second card from a different provider. Kept somewhere separate from the first. Cards get blocked, cloned, swallowed by machines and left behind in cafés. A backup turns a disaster into an inconvenience.
A savings account I deliberately make awkward to reach. No card attached. Two taps and a delay to move anything out of it. That small amount of friction has saved me more money than any deal-hunting ever has.
Cash, and how much of it
Some countries run almost entirely on cards. Others still expect notes for taxis, markets, small guesthouses and anything outside a city. Assuming either extreme will cost you.
My rule is to withdraw larger amounts less often, because most cash machine fees are fixed rather than proportional. One withdrawal of 400 units beats four withdrawals of 100 every single time. I keep a small emergency reserve in a widely accepted currency, tucked somewhere that is not my wallet, and I top up local cash only when I can see I will need it.
I also decline the machine’s offer to convert for me. Same trap as the card terminal, different screen.
The Habits That Save More Than Any Product
Choosing the right account gets you most of the way there. The rest is behaviour, and it is unglamorous.
- Tell your bank where you are going, or make sure the app is tracking your location properly. A frozen card in a country where you know nobody is a genuinely bad afternoon.
- Check statements weekly. Not monthly. Small fraudulent charges are often tested before large ones, and catching the first one saves you the second.
- Pay in local currency. Every time. No exceptions, no matter how helpfully the terminal phrases the question.
- Keep screenshots of card numbers and support lines somewhere you can reach without your phone.
- Watch the timing of big transfers. Rates move. If you are moving a large sum and it is not urgent, waiting a few days occasionally matters.
None of this is difficult. It is just a set of small decisions, made consistently, in situations where the easy option is usually the expensive one.
The Bottom Line
Managing money well on the road is not about being frugal. It is about refusing to pay for things that carry no value, and being deliberate with a handful of choices that most travellers make on autopilot.
Set the structure up once, at home, before you go. Separate what you spend from what you keep. Carry a backup. Learn to recognise the moment you are being quietly charged for convenience, and say no.
Do that, and the money you save stops being an abstraction on a statement. It becomes another country, another month, another trip you did not think you could afford.
