Sending a Large Amount Abroad (Buying Property, Tuition, Salary)
By Today's Currency Rates · Updated June 20, 2026
When you send a large amount abroad — a deposit on a property, a year’s tuition, or a salary paid across borders — the exchange rate matters far more than the headline transfer fee. On a small transfer a fixed fee dominates; on a large one, even a tiny difference in the rate can dwarf any fee, often by a wide margin. Getting the rate right is where the real money is saved or lost.
Why the rate markup matters more on big sums
Most of the cost of an international transfer is hidden in the exchange rate, not the visible fee. The provider quotes you a rate that is a little worse than the true mid-market rate — the interbank midpoint — and pockets the difference. That difference is called the markup or spread, and because it’s a percentage, it scales with the size of your transfer.
Consider a transfer of 300,000 of your home currency:
| Markup on the rate | Approximate cost |
|---|---|
| 0.5% | ~1,500 |
| 1.5% | ~4,500 |
| 3.0% | ~9,000 |
The gap between a 0.5% markup and a 3% markup is around 7,500 on this single transfer — vastly more than any fixed fee of, say, 10 or 20. On large sums, a “free” transfer with a 3% markup is far more expensive than a transfer that charges a fee but uses a tight 0.5% markup.
Compare the all-in rate, not the advertised fee
To compare providers fairly, ignore the words “no fees” or “zero commission” and ask a single question: how many units of the destination currency will actually land in the account? That figure already includes both the fee and the markup. Divide it by the amount you send and compare it against the mid-market rate on the day. The provider that delivers the most is the cheapest, full stop. Our cheapest way to send money abroad guide walks through this comparison in more detail.
Forward contracts and rate locks, at a high level
For large transfers tied to a future date — a property completion months away, or tuition due next term — some providers let you fix today’s rate for a future payment, or lock a rate for a window of time. This is sometimes called a forward contract or rate lock.
The point isn’t to beat the market; it’s certainty. If your budget only works at a particular rate, locking it removes the risk of the rate moving against you before the money is due. The trade-off is that you also give up any benefit if the rate moves in your favour. Used as insurance rather than speculation, a lock can make sense for a payment you cannot afford to have grow.
Timing: don’t try to time the market
Exchange rates move constantly and unpredictably, and no one reliably forecasts them. Waiting for a “better” rate on a payment with a deadline is a gamble that can easily backfire. A calmer approach is to decide what rate makes your purchase work, act when you see a rate at or near it, and not agonise over small daily swings. Checking the live rate — for example GBP to USD — tells you where the mid-market sits today so you can judge a quote against it.
Paperwork and compliance to expect
Large transfers attract more scrutiny, and that’s normal. Expect to:
- Verify your identity with official documents.
- Show the source of funds — for example a property contract, sale proceeds, or savings history.
- Explain the purpose of the payment.
- Allow extra processing time, as large amounts may be reviewed before they’re released.
Having documents ready in advance prevents delays at exactly the moment a deadline is approaching.
Splitting to manage risk
For very large sums, some people split a transfer across more than one provider or across a few dates. This can reduce single-point-of-failure risk, spread timing exposure, and keep individual amounts within comfortable limits. The downside is more admin and potentially more total fees, so weigh it against the size and urgency of your payment.
