We calculate your savings by comparing a panel of banks to work out the average FX fees they charge cardholders when spending abroad. The banks used for this panel are:
- Lloyds Bank
- HSBC
- RBS
- Barclays
We calculate the cost of your transaction with each of the four popular current accounts. We then take the average of those and remove the amount it actually cost you by using Currensea, giving you the displayed savings figure.
