International Money Transfer Cost Calculator

What this calculator does and who it's for

This tool estimates how much of your money actually arrives when you send it abroad — and how that figure changes depending on who moves it. It compares three types of provider side by side: a high street bank, a dedicated foreign exchange specialist, and a transparent transfer app such as Wise. Enter an amount, choose what you are sending (GBP, USD or EUR) and the destination currency (from sterling and the US dollar and euro through to the UAE dirham, Thai baht, Singapore dollar, Australian dollar, Swiss franc, Hong Kong dollar and Japanese yen), and it shows the amount received under each, the saving versus the bank, and the sterling equivalent of that saving. It is built for expats, cross-border property buyers, and anyone moving pension, rental or business income between currencies — the people for whom a hidden margin quietly repeats on every transfer. It sits alongside the rest of our financial tools and our international transfers hub.

Why the exchange rate you see isn't the rate you get

Most people look at the mid-market rate — the interbank rate quoted on Google or a currency site — and assume that is what they will receive. In practice every provider adds a spread: they buy and sell currency at slightly worse rates than the interbank rate and keep the difference. Because the spread is a percentage of the whole amount, it is the single biggest driver of cost on larger transfers, and it is far less visible than a flat fee. A bank can advertise “no transfer fee” while still earning several hundred pounds on the spread alone. This calculator is designed to make that invisible cost visible.

How the calculation works

The tool takes the indicative mid-market rate for your chosen currency pair and applies each provider profile in the same way a real transfer works. For every provider it first deducts any flat fee from your send amount, converts the remainder at the mid-market rate, and then reduces the result by that provider's spread. In other words:

• Amount received = (send amount − flat fee) × mid-market rate × (1 − spread)
• Saving vs bank = specialist (or app) amount received − bank amount received
• Sterling equivalent = that saving converted back to GBP at the mid-market rate

The three profiles it compares are deliberately representative rather than tied to any one brand. The high street bank is modelled at around a 2.5% spread plus a £25 flat fee; the FX specialist at around 0.4% with no flat fee; and the transfer app at around 0.5% with a transparent charge and no hidden markup. When your transfer reaches roughly £50,000 in sterling terms, the tool flags it as a large transfer and points to services — forward contracts, limit orders, a named dealer — that only become available at that scale.

Reading your result — a worked example

Suppose you are sending £20,000 to euros. At an indicative mid-market rate, the bank profile deducts its £25 fee, converts the rest, and shaves off roughly 2.5% — so a meaningful slice of the transfer never reaches the recipient. The specialist profile takes no flat fee and shaves off only about 0.4%, and the app profile about 0.5%. The panel shows each amount received in euros, then the extra euros the specialist and app deliver over the bank, and finally that advantage expressed back in pounds. On a £20,000 transfer the difference between a ~2.5% bank spread and a ~0.4% specialist spread is in the region of £400 — on a single transfer. The headline you should take away is not the exact figure, which depends on live rates, but the size and direction of the gap, and the fact that it repeats every time you move money.

Assumptions and limitations

Treat the output as an illustration, not a quote. The exchange rates are static approximations of mid-2026 levels rather than a live feed, so they will drift away from the market over time; the spread and fee figures are typical estimates for each provider type, not the terms of any specific provider, and real pricing varies with the amount, the currency pair, the payment method and the day. The tool prices spot transfers only — it does not model forward contracts, limit orders, receiving-bank charges, or the correspondent-bank fees that can be deducted mid-route on some payments. It also assumes you are comparing like-for-like delivery speed. Use it to understand the shape of the cost, then confirm the real numbers with a live quote before you transfer.

Why it matters — and what to do next

For a one-off transfer the spread is a nuisance; for a life lived across currencies it is a recurring leak. Expats receiving a UK pension, landlords repatriating rental income, and families supporting relatives abroad face the same margin on every single payment, and small percentages compound into serious money over the years. That is why managing the rate — and, for larger or scheduled amounts, the timing — is worth doing deliberately. Our guide on reducing international transfer fees covers the practical steps, and managing currency risk as an expat looks at protecting yourself from adverse rate moves. If you are also budgeting for a move, the cost of living calculator helps you work out how much you genuinely need in the destination currency, and if a UK asset sale is funding the transfer, check the tax first with the CGT calculator for non-residents.
