One thing to be aware of is that if you make a currency exchange on Revolut during the weekend, you’ll be charged a markup. That’s because the interbank rate is always fluctuating. Therefore, it may not be the same on a Monday as it was on the previous Friday. The markup is 0.5% for the 15 major currencies and 1% for the others. Also, remember that card payment, ATM withdrawals and money transfers abroad imply a currency exchange. Therefore, the weekend markup applies in all of these cases. The solution to this is to exchange one of the 29 currencies that Revolut supports in advance (i.e. on a weekday). Then you won't have to pay this fee.
