As provided by Bobo, here is a useful link to calculate any fees by using Paypal.
[Only registered and activated users can see links. ]
It is also worth noting that if the money is sent as a 'gift' there are no fees applied.
Edited and changed link after the report below. . .there may be better, I'll leave it to gunner to alter it if he knows of any, this was just chosen at random..seems clean.
