• A perpetual loan is a pre-approved loan issued by a financial institution to a borrower that can be reused.

  • In the case of perpetual loans, such as credit cards, after the borrower has started to pay the balance, he can take the funds again - this means that this is a revolving loan.
  • An open loan differs from a closed loan in how credit is provided to the borrower and whether the borrower can borrow the funds again.
