The rate on this page is the mid-market rate: the midpoint between what buyers and sellers of USD and STN are paying on the wholesale market. Banks and money transfer providers rarely give you that rate. Most build their profit into the exchange rate itself, quoting you a rate some way below mid-market and often advertising the transfer as "fee free". High-street banks commonly take 2-4% this way; specialist transfer services and brokers usually take much less. The gap matters most on large amounts: on a 50,000 USD transfer, the difference between a 3% and a 0.5% margin is 1,250 USD. Before you send, compare the rate you're offered against the mid-market rate here, and ask for the total amount that will arrive rather than the fee alone.
