A loan is a type of debt. Like all debt instruments, a loan entails the redistribution of financial assets over time, between the lender and the borrower.

The borrower initially receives an amount of money from the lender,

which they pay back, usually but not always in regular installments, to the lender. This service is generally provided at a cost, referred to as interest on the debt. A loan is of the annuity type if the amount paid periodically (for paying off and interest together) is fixed.

A borrower may be subject to certain restrictions known as loan covenants under the terms of the loan.

Legally, a loan is a contractual promise between two parties where one party, the creditor, agrees to provide a sum of money to a debtor, who promises to return the money to the creditor either in one lump sum or in parts over a fixed period in time. This agreement may include providing additional payments of rental charges on the funds advanced to the debtor for the time the funds are in the hands of the debtor (interest).
