Why Is My Exchange Rate Worse Than Google’s?

The Rate Google Shows You

The rate on Google, and in the news, is the mid-market rate, sometimes called the interbank or spot rate.

It’s the midpoint between what buyers are bidding and what sellers are asking for a currency on the global market where banks trade with each other. As a reference, it’s the fairest single number for what a currency is worth at that moment. But it’s a wholesale rate for large transactions between financial institutions, not a retail rate offered to individuals. Think of it like the wholesale price of a product: it tells you the underlying value, but it’s not the price you pay at the shop. That’s why the mid-market rate is the right benchmark to judge an offer against, but not a rate you’ll actually receive.

The Spread: How Providers Get Paid

When a bank, app, or bureau converts your money, they give you a rate slightly worse than mid-market. That difference is the spread, and it’s the main way they earn from the transaction.

The spread is often invisible, which is exactly why it catches people out. A provider can advertise “no fees” and still make good money by handing you a rate a few percent away from mid-market. There’s no separate charge to see; the cost is baked into the rate itself. The size of the spread varies hugely: some providers sit very close to mid-market, while airport bureaux, hotels, and some card conversions can be several percent away. Because it’s hidden in the rate, the only way to compare providers fairly is on the total amount you actually receive, not on advertised fees.

What the Spread Costs

Suppose the mid-market rate is 1 unit of your currency to 1.27 of another, and you’re converting 2,000.

• At the mid-market rate, 2,000 would give you 2,540.
• A provider offering a 2.4% spread gives you a rate of about 1.24, so you receive 2,480.
• The difference, 60, is the cost of the spread, even though no fee was itemised.

On a larger sum the same percentage costs proportionally more, which is why the spread matters most on big transfers like paying for a property, tuition, or a car abroad. A 2 to 4 percent spread sounds small until it’s applied to a large amount, where it can quietly cost hundreds. Our guide on how exchange rates work covers the conversion arithmetic in more detail.

Fees on Top of the Spread

Some providers add an explicit fee as well as the spread, and this is actually the more honest arrangement.

A transparent provider might give you a rate at or very near mid-market and charge a clear, separate fee, so you can see exactly what the conversion costs. That’s often cheaper overall than a “no fee” service hiding a wide spread, because the visible fee is smaller than the invisible margin. The lesson is that “no fees” is not the same as “no cost,” and a headline fee of zero can be the most expensive option once the spread is included. Always compare on the bottom line: how much of the target currency actually lands, for a given amount sent.

The Dynamic Currency Conversion Trap

One situation deserves a specific warning, because it’s where people lose money without realising they had a choice.

When you pay by card abroad or withdraw from a foreign cash machine, the terminal sometimes offers to charge you in your home currency instead of the local one. This is dynamic currency conversion, and it almost always uses a worse rate than your own bank would. It’s presented as a convenience, letting you “see the amount in your own money,” but that convenience carries a markup that can be several percent. The right choice is nearly always to pay in the local currency and let your own bank handle the conversion, which is usually closer to mid-market. If a terminal asks which currency to charge in, choose the local one.

How to Keep More of Your Money

• Compare providers on the total amount received, not on advertised fees, since the spread is where the real cost usually hides.
• Treat the mid-market rate as your benchmark and judge how far each offer sits from it.
• Be wary of “no fee” claims, which often mean a wide, invisible spread rather than genuinely free conversion.
• Avoid airport and hotel currency exchange, which tend to have the widest spreads.
• When paying by card abroad, always choose the local currency to sidestep dynamic currency conversion.
• For large transfers, shop around harder, since a small percentage difference on a big sum is real money.

Frequently Asked Questions

Why is the exchange rate I get worse than Google’s?

Because Google shows the mid-market rate, a wholesale reference figure banks trade at, while providers give you a retail rate slightly worse than that. The difference, called the spread, is how they earn from the conversion. It’s usually built into the rate rather than shown as a separate fee.

What is the mid-market rate?

The midpoint between the buying and selling prices for a currency on the global interbank market, and the fairest single benchmark for what a currency is worth. It’s the rate Google and news outlets display, but it’s a wholesale rate for large institutional trades, not one offered to individuals.

What is a currency exchange spread?

The gap between the mid-market rate and the rate a provider offers you. It’s the main way banks, apps, and bureaux make money on currency, and it’s often invisible because it’s baked into the rate. Spreads range from a fraction of a percent to several percent depending on the provider.

Does “no fees” mean free currency exchange?

No. A provider can advertise no fees and still profit from a wide spread hidden in the rate. Often a service with a small visible fee but a near-mid-market rate is cheaper overall. Always compare on how much you actually receive, not on the advertised fee.

Should I pay in local currency or my home currency abroad?

Local currency, almost always. When a card terminal offers to charge in your home currency, that’s dynamic currency conversion, which uses a worse rate set by the merchant’s processor and can cost several percent. Choosing the local currency lets your own bank convert at a rate usually closer to mid-market.

Why does the spread matter more on large amounts?

Because it’s a percentage of the amount converted, so the same spread costs proportionally more on a bigger sum. A 2 to 4 percent spread is minor on a small holiday exchange but can cost hundreds on a large transfer for tuition, a property, or a vehicle, where shopping around pays off most.

How do I find the cheapest way to convert currency?

Benchmark against the mid-market rate, then compare providers on the total amount received for the same amount sent, counting both the spread and any fee. Avoid airport and hotel exchange, choose local currency on card terminals abroad, and for large sums compare several specialist providers rather than defaulting to your bank.

The Bottom Line

The rate Google shows is the mid-market rate, a wholesale benchmark you won’t actually receive; the worse rate you’re offered reflects the provider’s spread, which is how they make money and is usually hidden in the rate rather than shown as a fee. Judge every offer against the mid-market rate, compare on the amount you actually receive, be sceptical of “no fees,” and always pay in local currency abroad. Get a clean benchmark conversion from the currency converter, and shop around hardest on large transfers, where a small percentage is real money.
