When you sign up for a paypal business account, you are essentially having a "virtual bank account". Your money will be stored in your paypal account if you do not withdraw the money from your paypal account. Unfortunately, Paypal do not pay you any interest like the bank.

To withdraw money from your paypal account, you can simply log in to your paypal account, click on withdraw. Then indicate the bank account that you wish to withdraw to. [You need to add a bank account first]

There is no service charge for withdrawal of more than SGD$200. But if the withdrawal amount is less than SGD$200, there will be a SGD1.00 charge.

Withdrawal takes about 5 to 7 business days.
