Hi Wapiti,
From PostFinance to IB UK, I used to select “shared cost” and paid between 6 to 10 CHF depending on the amount.
This was taken from the amount transferred.
EDIT: I have been charged 20 CHF + 2 CHF with the “our cost” method. I will revert back to the “shared cost” method for the next transfers
One day I tried to select “our cost” and was happy to see that PostFinance charged 2 CHF for the transfer.
The 2 CHF are taken from your account and the full amount transferred reaches IB UK.

Fees that apply for international GIRO from PostFinance
It takes 1 or 2 business days to arrive at IB UK.
