It depends on a single number: what the recipient ends up with. A provider can advertise low international money transfer fees and still cost you more than a competitor, because the advertised fee and the exchange rate are two separate charges and only one of them is usually on the banner. Compare the rate applied, every fee charged on both ends, and the amount that actually lands — for the exact sum you are sending, to the exact country.
What are international money transfer fees actually made of?
Two charges, set independently. Under ASIC's Moneysmart guidance on sending money overseas, providers choose the exchange rate they use and also charge fees, and the costs depend on how much you send, where you send it and how you send it. The same guidance recommends shopping around, because different companies can charge very different prices and you save by comparing exchange rates and fees rather than either one alone.
That framing matters because the two halves behave differently when you shop. The fee is usually quoted up front in your own currency. The exchange rate is the part that is easy to gloss over, since a rate that looks like a decimal detail is in practice a percentage shaved off your money. Comparing only the fee is what makes an expensive transfer look cheap.
Moneysmart breaks the fee side into three things worth asking about directly: whether the conversion fee is a flat rate, a percentage or both, whether the receiver pays any fees, and the "margin" fee to convert your currency. Ask those three questions of any provider before you compare, because a flat fee and a percentage fee scale in opposite directions as your transfer grows.
Is the mid-market rate the rate you get?
Not necessarily, and this is where official guidance stops short. No regulator source reached for this answer gives a single agreed definition of the "mid-market rate"; the term is used widely in comparisons but is not settled by the official material covered here. If you need a definition for a dispute or a disclosure, ask the provider in writing which benchmark it prices against, and if you are sending from the UK, the Financial Conduct Authority is the regulator whose pricing-transparency expectations apply.
What the UK regulator does define is the "reference rate", described as a benchmark rate a firm uses to calculate its pricing. That gives you a workable way to compare without arguing over vocabulary: instead of asking whether a provider offers the mid-market rate, ask what benchmark it measures its own rate against and whether it shows you the gap in money terms, not just a percentage.
Moneysmart makes the same point from the consumer side: check how much your money is worth in the other currency, whether the advertised rate is the rate you actually get, and whether the rate is guaranteed or can still change before the money moves. An unguaranteed rate turns a quoted comparison into an estimate.
How do you read the margin? A worked example
The FCA's good-practice examples use the same starting point throughout — £100 in, with a reference rate of 1 GBP to 1.30 USD — which is exactly why they are useful for learning the mechanics. Read them as two different shapes of cost, not as a ranking of providers.
| What you see | Example A (markup only) | Example B (fixed fee only) |
|---|---|---|
| Amount you convert | £100.00 | £100.00 |
| Exchange rate applied | 1.26 (includes a 3% markup charge) | 1.30 |
| Fixed fee | £0.00 | £5.00 |
| Total you pay | £100.00 | £105.00 |
| Total fees shown | £3.00 | — |
| Recipient receives | $126.10 | $130.00 |
Both rows come from the FCA's good and poor practice examples on international payment pricing transparency. The first is the case worth studying: the fixed fee is £0.00, yet the firm still presents £3.00 in total fees, because the markup in the exchange rate is being communicated as a cost. The recipient receives $126.10 rather than the $130.00 the reference rate would have produced.
That is the whole trick of margin maths. A transfer with no fixed fee is not free; the cost has simply moved into the rate. The FCA lists as poor practice the mirror image — highlighting the absence of a fixed fee as a "zero cost transaction" while charging a markup — and says firms should communicate markups above their reference rate as a cost to the consumer. So if a provider's page shows you a fee of zero and nothing else, you are looking at half a price.
The second row shows the other shape: a £5.00 fixed fee charged on top, at the untouched 1.30 reference rate, so you pay £105.00 and the recipient gets $130.00. Which shape costs you less depends on your amount and your corridor, and no regulator source here publishes figures that let anyone declare a winner for a given transfer.
Do receiving-bank fees change the amount that arrives?
Yes, and they sit outside the comparison you just did. The FCA's own worked example carries the note that intermediary bank and/or recipient bank fees may apply and might reduce the recipient's amount below $130.00. In other words, the amount shown at checkout is a figure the sending firm controls up to a point, and the rest is deducted further along the chain.
The practical check is boring but decisive: ask your recipient what actually landed, and compare it to what you were shown. If the two differ, the gap is either a receiving-bank deduction or an intermediary deduction, and the recipient's bank is the authority that can tell you which. Moneysmart folds this into the comparison stage by telling you to check whether the receiver pays any fees before you send.
This is also the reason a comparison that only looks at the sender's screen can mislead you on remittance corridors where intermediary banks are routine. Two providers can quote identical rates and fees and still deliver different amounts.
Do transfer limits and speed matter to the cost?
They change which comparison is valid. Moneysmart lists transfer time — instant, a few minutes, or up to five business days — and the transfer amount, meaning the smallest or largest amount you can send, among the features to compare alongside rate and fees.
Limits matter because a cap can push a large transfer into two or three separate transactions, and each transaction carries its own fee structure. Speed matters because of the guarantee question above: a rate that can move during a five-business-day window is not the same product as a locked rate, however similar the two look side by side.
How do you compare providers without picking a winner?
Use the regulator checklists rather than a headline number. The FCA's review looked at whether firms provided the amount to be remitted in GBP, the exchange rate that will be applied, the amount a recipient receives in local currency, the markup above the reference rate, any variable fees, any fixed fees per transaction, and the total remittance fees. That list is a usable personal checklist: if a quote is missing two or three of those lines, you cannot fully price it yet.
For the shopping itself, Moneysmart points to independent comparison sites — SaverAsia for money sent from Australia to countries in Asia, and the World Bank's Remittance Prices Worldwide for other international transfers. Neither is a recommendation of any individual company, and neither settles what your own bank or provider will charge you on the day; they are starting points for a corridor, after which you still check the seven items above against the actual quote.
What the official guidance does not settle
Two gaps are worth stating plainly rather than guessing around. First, US remittance disclosure and cancellation rights are not covered here: the Consumer Financial Protection Bureau's remittance-transfer pages could not be retrieved for this answer, so any statement about US-specific cancellation or disclosure rules would be invention. If you are sending from the United States, ask the CFPB directly about disclosure and cancellation rights for your transfer.
Second, as noted above, no regulator source reached here defines the "mid-market rate". The closest official anchor is the FCA's "reference rate", and the practical move is to ask the firm what benchmark it uses. Beyond that, no regulator in this material publishes a ranking of cheapest providers for a given corridor, so any claim about the cheapest way to send money internationally for your specific pair of countries is a claim this answer cannot source for you.
