The total cost of an international money transfer is made up of three layers: the transfer fee (usually £15–£40 at high-street banks), correspondent or intermediary bank fees on SWIFT transfers (£10–£25 per intermediary), and the FX margin applied to the exchange rate (typically 2–4% at banks, 0.3–0.5% at specialist brokers). For most transfers above a few thousand pounds, the FX margin is by far the largest cost — and it’s the one most consumers don’t see.
This guide breaks down each cost layer with real figures, shows how the same £50,000 transfer can cost £1,800 at a bank versus £230 at a specialist broker, and explains what to check before sending.
The three layers of an international transfer fee
Most people think of an international transfer fee as a single line item. In practice, it’s three separate costs that compound on the same transaction:
| Cost layer | What it covers | Typical range | Visible to sender? |
|---|---|---|---|
| Transfer fee | Flat fee for processing the payment | £0–£40 | Yes — shown upfront |
| Correspondent/intermediary bank fees | Charges from banks in the SWIFT chain between sender and recipient | £10–£25 per intermediary | Often invisible until recipient confirms what arrived |
| FX margin | Markup added to the exchange rate during currency conversion | 0.3%–4% above mid-market | Hidden in the rate — most consumers never see it |
On a £500 transfer, the £15 transfer fee dominates. On a £50,000 transfer, the transfer fee is rounding error — the FX margin is everything. This is why the same provider can look cheap for small payments and expensive for large ones, depending entirely on which layer matters most for the transfer size.
Layer 1: Transfer fees
The transfer fee is the flat amount your provider charges to initiate the payment. It’s the visible cost on every quote and the figure most providers compete on publicly.
Typical transfer fees in 2026:
| Provider type | Domestic GBP (Faster Payments) | International SWIFT | SEPA (EUR within Europe) |
|---|---|---|---|
| High-street bank | Free | £15–£40 | Free–£15 |
| Challenger bank (Monzo, Starling) | Free | Free–£20 | Free |
| Multi-currency app (Wise, Revolut) | Free | £1–£15 | Free |
| Specialist currency broker | Free | £0–£15 | Free |
The transfer fee is usually the same regardless of amount — it costs a bank the same to send £500 or £500,000 as a single transaction. This is why focusing on transfer fees alone is misleading for larger payments.
Layer 2: Correspondent and intermediary bank fees
For SWIFT-based international transfers, payments often pass through one or more correspondent banks between the sender’s bank and the recipient’s bank. Each correspondent typically takes a fee — usually £10–£25 — from the transferred amount.
These fees are not always disclosed in advance because the sender’s bank doesn’t always know which correspondents the payment will route through. The recipient sees the shortfall when the funds land — sometimes £30, £40, or £50 less than the sender expected, with no clear breakdown.
Three SWIFT charging options determine who absorbs these fees:
- OUR — the sender pays all charges, including any correspondent fees. The recipient receives the full amount
- BEN — the beneficiary pays all charges. The amount deducted from the transfer along the way is borne by the recipient
- SHA — the sender pays their own bank’s fees; correspondent fees are deducted from the transfer. Most common default
For payments where the recipient must receive a specific amount — invoices, tax payments, school fees — using OUR rather than SHA avoids the recipient receiving an unexpected shortfall. The trade-off is higher upfront cost to the sender.
SEPA payments within Europe don’t incur correspondent fees because SEPA settles directly between participating banks without an intermediary chain. This is one reason a euro transfer within the SEPA zone is materially cheaper than a SWIFT transfer to the same recipient.
Layer 3: FX margin — the largest hidden cost
The FX margin is the markup your provider applies to the exchange rate when converting currencies. It’s the difference between the mid-market rate (the rate banks use to trade with each other, available on Reuters or Bloomberg) and the rate you actually receive.
FX margin is the largest hidden cost in international transfers because:
- It’s not shown as a separate fee — it’s baked into the exchange rate
- It scales with the transfer size, unlike the flat transfer fee
- Banks rarely disclose it, and most consumers don’t know the mid-market rate to compare against
Typical FX margins in 2026:
| Provider type | Typical FX margin above mid-market | Cost on £50,000 GBP/EUR conversion |
|---|---|---|
| High-street bank | 2.5%–4% | £1,250–£2,000 |
| Challenger bank | 0.5%–1.5% | £250–£750 |
| Multi-currency app | 0.3%–1% | £150–£500 |
| Specialist currency broker | 0.3%–0.5% | £150–£250 |
The gap between a high-street bank and a specialist broker on a single £50,000 transfer is £1,000–£1,850. Multiplied across termly school fees, quarterly business payments, or repeated property completions, it adds up quickly.
As Anthony Bull, CEO of Cambridge Currencies, puts it: “Clients arrive focused on the £25 SWIFT fee and miss that their bank is charging a 3% margin on the conversion. On a £100,000 property transfer, that’s £3,000 hidden in the rate — bigger than every other fee on the transaction combined. The transfer fee matters; the conversion cost matters far more.”
Worked example: £50,000 GBP to EUR
Same transfer amount, same recipient, four different providers. Mid-market rate assumed at €1.1850 (illustrative — verify with a live source). The figures below show the all-in cost difference:
| Provider | Transfer fee | FX margin | Effective rate | EUR received | Total cost vs mid-market |
|---|---|---|---|---|---|
| High-street bank (SWIFT, 3% margin) | £25 | 3.00% | €1.1495 | €57,475 | £1,800 |
| Challenger bank (SEPA, 1% margin) | £0 | 1.00% | €1.1732 | €58,660 | £600 |
| Multi-currency app (SEPA, 0.5% margin) | £5 | 0.50% | €1.1791 | €58,955 | £305 |
| Specialist currency broker (SEPA, 0.4% margin) | £0 | 0.40% | €1.1803 | €59,015 | £230 |
The difference between the bank and the broker on this single transfer is £1,570 — almost twice the average UK weekly wage, on a one-off transaction. The bank’s £25 transfer fee is essentially irrelevant in the context of the 3% margin.
Other fees to watch for
Receiving fees
Some banks charge a fee to receive an inbound international transfer. UK high-street banks typically charge £6–£10 for an incoming SWIFT transfer to a personal account; business accounts can be more. Recipients can avoid this by using a multi-currency account or a bank that doesn’t charge for incoming transfers.
Card payment surcharges
Funding a transfer with a credit or debit card usually costs 1–3% extra. Most specialist brokers don’t accept card funding for this reason — bank transfer is the only funding method.
Same-day or urgent fees
For payments where same-day settlement matters — property completions, contractual deadlines — banks charge an additional £20–£30 for CHAPS or urgent SWIFT. Most specialist brokers include same-day settlement at no extra cost.
Dynamic Currency Conversion (DCC)
If you’re paying abroad with a card and the merchant offers to convert to your home currency at checkout, that’s Dynamic Currency Conversion. The merchant’s rate is almost always worse than your card network’s rate — typically 3–7% worse. Always decline DCC and pay in the local currency.
How to compare providers properly
Comparing providers on transfer fee alone is the most common mistake. To compare like for like:
- Get a live mid-market rate from a neutral source (Reuters, Bloomberg, or a currency converter that uses interbank rates)
- Request a live quote from each provider for the exact amount you intend to send. Quotes are firm only for short windows — usually under 30 seconds for live broker quotes
- Calculate the FX margin as the percentage difference between the provider’s rate and the mid-market rate
- Add the transfer fee in the source currency
- Check for correspondent bank fees if the provider uses SWIFT. Ask whether OUR, BEN, or SHA charging is being used
- Compare the final amount the recipient will receive — this is the single number that matters most
If a provider won’t quote a live rate before you fund the transfer, treat that as a warning sign. Reputable providers quote firmly and lock the rate at the point of agreement.
How to reduce international transfer fees
- Use the right rail for the destination. SEPA for euros within Europe is free and instant; SWIFT is for everywhere else. Routing a euro payment to a French account through SWIFT when SEPA would settle it for free is a common, expensive mistake
- For transfers above £3,000, use a specialist broker. The FX margin difference outweighs any other consideration at this size
- Consider a forward contract for predictable future payments. If you know you’ll need to pay tuition, rent, or invoices in a specific currency over the next 6–12 months, a forward contract locks today’s rate against a small deposit — protecting against currency moves
- Avoid card-funded transfers. The 1–3% card surcharge typically wipes out any FX advantage
- Decline Dynamic Currency Conversion at point-of-sale. The merchant’s rate is almost always worse than your card’s
- Don’t pay for “premium” or “concierge” transfer services unless they include specific FX advantages. Many premium account features are unrelated to international transfer cost
- Time larger conversions when you can. Exchange rates move daily, and a 1% favourable swing on a £100,000 transfer is £1,000. For non-urgent transfers, watching the rate for a few days can pay back the effort
When the transfer fee matters more than the FX margin
For small or domestic-currency transfers, the FX margin doesn’t exist or is negligible. In these cases, the flat transfer fee dominates:
- Small transfers (under £500): a £20 bank fee is 4% of the transfer. A challenger bank or multi-currency app’s near-zero transfer fee almost always wins
- Same-currency transfers (e.g., GBP to a UK-held GBP account from overseas): no FX conversion happens, so the only cost is the SWIFT or wire fee
- High-frequency small payments: a multi-currency account that holds balances in EUR or USD can avoid converting each transaction individually
The rule of thumb: below £3,000, optimise for transfer fee. Above £3,000, optimise for FX margin.
Frequently asked questions
An international transfer has three main cost layers: the transfer fee (typically £15–£40 at high-street banks), correspondent or intermediary bank fees on SWIFT transfers (£10–£25 per intermediary), and the FX margin applied to the exchange rate (2–4% at banks, 0.3–0.5% at specialist brokers). For transfers above a few thousand pounds, the FX margin is by far the largest cost.
The FX margin is the markup a provider adds to the mid-market exchange rate when converting currencies. It’s the difference between the interbank rate (the rate banks use with each other) and the rate you actually receive. UK high-street banks typically charge 2–4% above mid-market; specialist brokers typically charge 0.3–0.5%.
UK high-street banks typically charge £15–£40 as a transfer fee, plus an FX margin of 2–4% on currency conversion. On a £50,000 transfer to euros, total bank costs typically come to £1,300–£2,000, with the FX margin accounting for most of it. Specialist currency brokers usually charge no transfer fee and around 0.4% FX margin.
OUR means the sender pays all charges including correspondent fees, and the recipient receives the full amount. BEN means the beneficiary pays all charges through deductions from the transfer. SHA means the sender pays their own bank’s fees, with correspondent fees deducted from the transfer along the way. SHA is the most common default; OUR is used when the recipient must receive a specific amount.
Yes. The FX margin is the largest hidden cost — it’s built into the exchange rate rather than shown as a separate fee. Correspondent bank fees on SWIFT transfers are also often invisible until the recipient sees the shortfall. To compare providers properly, always compare the final amount the recipient receives, not just the transfer fee.
For transfers above £3,000, use a specialist currency broker rather than a bank — the FX margin difference outweighs every other consideration at this size. Use SEPA rather than SWIFT for euro payments within Europe. Consider a forward contract to lock in today’s rate for known future payments. Avoid card-funded transfers and decline Dynamic Currency Conversion at point of sale.
For small transfers (under £500), a multi-currency app or challenger bank usually has the lowest combined cost. For larger transfers (£3,000+), a specialist currency broker is almost always cheapest because the tight FX margin outweighs everything else. For euro payments within the SEPA zone, SEPA is free at most providers regardless of size.
The shortfall is usually correspondent bank fees on a SWIFT transfer. When the transfer is sent under SHA charging, each correspondent bank in the chain deducts £10–£25 before passing the payment on. Using OUR charging instead means the sender pays these fees upfront and the recipient receives the full amount — useful for invoices and contractual payments where the amount must be exact.
