Well, i have just checked out the paypal personal fees policy as satyakam mentioned. Here is what i find out :

Purchase

Free

Get paid
2.4% to 3.4% + $0.30 USD

Personal Transfer

Free when the money comes from PayPal balance or bank account.
3.4% + $0.30 USD

when the money comes from a debit or credit card or PayPal Credit

(the sender decides who pays this fee).
