You've got two options for your pay day. Head to your account settings page, then click "Payout preferences" and you can choose the option that works best for you.
If you'd like to have your payouts automatically sent to the payment method you supplied, check the "enable automatic monthly transfers" box. Enabling this will send the money in your account balance to your bank account on the 5th of the month.
If you'd like to manually pay out your account balance, you can do this at any time from this page as well. Just hit that blue button at the top of the page and you'll see that balance in your bank account in an average of 1-3 business days.
