Is the exchange-rate markup a hidden fee?

Effectively, yes. Because it is built into the exchange rate rather than shown as a separate charge, most people never see it. A provider can advertise zero fees and still make money on the rate, which is why you should compare the amount actually delivered, not the headline fee.

How can I avoid paying the bank's exchange-rate markup?

Use a provider that passes on the real mid-market rate, such as Wise, and charges a small transparent fee instead of hiding a margin. Always check the mid-market rate first and compare the amount your recipient receives across providers.

How much do banks charge on the exchange rate?

It varies, but banks commonly add a markup of 2 to 4 percent on the exchange rate, and sometimes more for less common currencies. On a 1,000 dollar transfer, a 3 percent markup quietly costs about 30 dollars.

How Do Banks Make Money on Exchange Rates?

Q: How do banks make money on exchange rates?

Banks make money by giving you a worse exchange rate than the real mid-market rate and keeping the difference. This gap is called the markup or spread. Instead of charging a visible fee, they build their profit into the rate itself, which is why a currency exchange can look free but still cost you a few percent.

Q: What is the exchange-rate spread?

The spread is the difference between the rate at which a bank buys a currency and the rate at which it sells it. The mid-market rate sits in the middle. When you exchange money, you get the less favorable side of the spread, and the bank pockets the difference.

When you exchange currency or send money abroad through a bank, you are often told there is “no fee.” So how does the bank make money? The answer is one of the most important things to understand about foreign exchange — and once you see it, you will never look at an exchange rate the same way again. Here is exactly how banks profit on exchange rates, and how to stop paying more than you should.

The short version

Banks give you a worse exchange rate than the real mid-market rate and keep the difference.
This gap is the markup or spread — a hidden fee built into the rate.
It is why an exchange can look free but still cost 2–4%.
Avoid it by using a provider that passes on the real rate, like Wise.

How banks make money on exchange rates

Every currency has one true value at any moment: the mid-market rate, the midpoint of what the currency is trading at on the global market. Banks know this rate — they trade at it with each other. But when they sell currency to you, they quote a slightly worse rate and keep the difference. That difference is their profit. Because it is baked into the rate rather than shown as a line-item fee, most customers never notice it.

The spread, explained

Banks quote two rates for a currency: a buy rate (what they will pay you for it) and a sell rate (what they will charge you for it). The mid-market rate sits exactly between them, and the distance between the two is called the spread. Whichever way you are transacting, you get the less favorable side of the spread, and the bank pockets the gap. The wider the spread, the more the bank makes — and the less you get.

Why it stays hidden

A visible fee is easy to compare and easy to resent. A markup buried in the exchange rate is neither. This is exactly why so many services advertise “zero fees” or “no commission” — they are telling the truth about the fee while making their money on the rate instead. It is also why two providers can both claim to be free yet deliver very different amounts.

A worked example

Say the mid-market rate is 1 USD = 0.90 EUR. Your bank offers you 0.87 EUR and charges “no fee.” On a $1,000 exchange, you receive €870 instead of the €900 the real rate would give — a hidden cost of about €30, or roughly 3.3%. A provider charging a visible $5 fee at the real rate would leave you far better off.

How much do banks charge?

It varies by bank and currency, but a markup of 2% to 4% on the exchange rate is common, and it can be higher for less common currencies or for cash exchanges at airports and bureaux de change. On a $1,000 transfer, a 3% markup quietly costs about $30 — every single time.

How to avoid paying the markup

Use a mid-market provider. Services like Wise pass on the real mid-market rate and charge a small, transparent fee instead of hiding a margin.
Check the real rate first. Look up the mid-market rate on our converter so you have a benchmark.
Compare the amount delivered, not the advertised fee.
Avoid airport and hotel exchange desks, which usually have the widest spreads.
