The hidden cost in school fee payments

If you are paid in pounds and the school invoices in dirhams, somewhere between the two figures there is a foreign exchange spread, a wire fee, and a receiving bank fee. On a $40,000 annual bill, the difference between a poor setup and a good one is around $1,400 per child per year. Spread that across two children and six years of school, and you are looking at $17,000. The number is not life-changing, but it is the equivalent of a small saloon car, and most families pay it without ever noticing.

The reason it stays hidden is that high street banks bury their FX margin inside the headline exchange rate, then charge a flat wire fee that looks reasonable on its own. A 1.8 per cent FX margin on a $40,000 transfer is $720. The wire fee on top might be $30. Most parents look at the $30 and conclude the transfer was cheap. It was not.

The four accounts we tested

We chose four accounts that international families most frequently hold: Wise (formerly TransferWise), Revolut Premium, HSBC Expat (Channel Islands or Jersey-based), and Citigold International. Between them they cover three different propositions. Wise and Revolut are fintech wallets that hold balances in multiple currencies and convert at close to the mid-market rate. HSBC Expat is a traditional offshore bank with multi-currency sub-accounts and human relationship management. Citigold International is the premium tier of Citibank's global private banking, with the lowest FX margins for high balances but with eligibility thresholds.

We ignored crypto-based and stablecoin-based transfers. They can be cheaper for the FX leg, but school bursars do not accept them at the receiving end, and the cost of converting back into local fiat usually erases the saving. We also ignored international transfer services targeted at small businesses (OFX, Currencies Direct, Wise Business) because for a parent paying personal school fees, the personal accounts at Wise and Revolut deliver effectively the same FX rate with simpler tax reporting.

Use our fee planner first

Before you optimise the FX leg, make sure you know the total bill. Our fee comparison tool shows the all-in cost of any international school in our database, including the loading factors that the headline tuition does not capture. The right currency account matters far less than the right school.

What each one costs on a real payment

We modelled a single payment of GBP 32,000 into AED for a Dubai school invoice, then ran the same scenario for GBP into SGD, USD into EUR, and EUR into CHF. The table below shows the all-in cost for the GBP to AED leg. The pattern is similar across the other pairs.

The numbers move slightly with the currency pair and the day, but the ranking is stable. Wise and Revolut are within 10 per cent of each other and meaningfully cheaper than the traditional offshore banks. Citigold sits in the middle. The high street current account is the floor of the market in cost terms.

Which to choose for your situation

For most international parents, the right setup is a Wise account holding the salary currency, with the recipient currency (AED, SGD, USD, HKD, EUR) added as a sub-balance. Bursars accept local wire transfers from Wise balances, and the FX leg costs around 0.4 per cent rather than the 1.5 per cent that an HSBC Expat wire would cost. Wise does have monthly transfer ceilings that you may need to verify yourself on for school-fee-sized payments, and the verification adds two to three working days the first time. After that, transfers are same day for the major pairs.

Revolut Premium is broadly equivalent. The wrinkle is the FX allowance. Within the included monthly allowance, conversions are at the mid-market rate. Above the allowance, a 0.5 per cent fee applies. For a school fee of GBP 30,000 to 40,000, you will breach the included allowance in a single transaction unless you are on a higher tier. That is fine in absolute terms because the 0.5 per cent fee is still cheaper than a bank, but it eliminates Revolut's headline advantage.

HSBC Expat is the right choice when the relationship value (offshore mortgage eligibility, premium banking access, multi-jurisdiction tax reporting) outweighs the FX cost. For a family with offshore real estate, an income stream in two or more currencies, and an underlying mortgage relationship with HSBC, paying 0.8 to 1.2 per cent more on the FX is rational. For a family with one income, one currency and one bill to pay, it is not.

Citigold International is the right choice for clients who clear the USD 200,000 minimum balance threshold and value the global private banker relationship. If you are not at that level of assets, Wise plus a normal bank account is structurally cheaper and operationally simpler.

Two workarounds the schools rarely advertise

First, a number of international schools (notably in Dubai, Singapore and Hong Kong) accept payment in multiple currencies and will quote a USD or EUR fee on request even when their published price is in local currency. If you ask the bursar, the school sometimes pays the FX cost itself rather than charging you. This is most common at boarding schools with international parent populations and at fee tiers above USD 25,000. It is rare in the Gulf day schools where the published AED price is the only price.

Second, the international schools that accept termly direct debits (rather than wire transfers) usually offer a 0.5 to 1 per cent discount for that payment method. Wise, Revolut and the offshore banks all support termly direct debits in the major currencies. The discount more than pays for the entire FX margin in many cases.
