There are several differences between a loan and credit:
A loan provides access to all the requested money at once (when the loan is granted). However, credit lets you request the money according to your needs.
With a loan, you pay interest on all the amount borrowed from the bank, whereas with a credit, you only pay interest on the money you use (rather than on the total amount the bank makes available to you).
Once the entire loan principal has been repaid, the transaction is concluded, and you will not be able to access more money (unless you take out a new loan). The credit is renewed every year, allowing you to use this line of financing as needed.
