How Soon After an Instant Payment Does PayPal Deduct From Your Bank Account?

Setup Checking Account
In order to send an instant transfer from your PayPal account, you need to link a bank account and a credit card to your PayPal account. Log on to your PayPal account by going to PayPal.com and entering your PayPal e-mail address and password. Click the 'Sign In' button. Click the 'Profile' tab and select the 'Bank Accounts' option. Click the 'Add' button. Enter the routing number and account number for your bank account. Select the option to instantly confirm your account.
Setup Credit Card
In addition to linking a bank account, PayPal also requires you to link a credit card to use as a backup payment method should your bank account decline the instant transfer. Log on to your PayPal account by going to PayPal.com and entering your PayPal e-mail address and password. Click the 'Sign In' button. Click the 'Profile' tab and select the 'Credit Cards' option. Click the 'Add' button. Enter your credit card number, security ID from the back of the credit card, the credit card expiration date and your billing address. Select the option to instantly confirm your account.
How to Use Instant Transfer
Log on to your PayPal account by going to PayPal.com and entering your PayPal e-mail address and password. Click the 'Sign In' button. Click the 'Send Money' tab. Enter the PayPal e-mail address of the person you want to send instant money to and enter the amount of money you want to send. Click the 'Continue' button. Click the 'Change' button under the 'Payment Method' subsection. Select a bank account that says 'Instant Transfer.' Click the 'Continue' button. Review your information and click the 'Send Money' button to complete the instant payment.
How It Works
PayPal's instant transfer sends funds instantaneously to the designated recipient as soon as you click 'Send Money.' Once you complete the transaction, PayPal initiates an electronics fund transfer (EFT) from your bank account. This process typically takes three to five business days but ultimately depends on how quickly your bank processes EFT transfers. PayPal requires a credit card to backup the instant transfer in case your bank declines the EFT transaction. Typically, banks decline EFT transactions if insufficient funds exist in the account. If your bank declines the EFT transaction, PayPal will automatically bill the credit card linked to your account.
