What Is a Loan?

A loan is an agreement in which a lender provides money or property to a borrower, who agrees to return it under defined conditions. Those conditions usually cover how much is borrowed, how long repayment will take, and what the borrower pays for using the funds. That cost is typically expressed as an interest rate applied to the outstanding balance. Individuals use loans to buy homes and vehicles or to pay for education, while businesses use them to fund equipment, inventory, and expansion.

How Loans Work

Most loans begin with the principal, the original amount borrowed. Repayment usually happens in regular installments that combine interest with a portion of the principal. Because each payment reduces the balance, the share going toward principal tends to grow over time, a process called amortization.

Loans may be secured or unsecured. A secured loan is backed by collateral, an asset the lender can claim if the borrower stops paying. An unsecured loan has no such backing, so lenders typically weigh the borrower's income and credit history more heavily when deciding whether to lend and on what terms.

If a borrower fails to meet the agreed terms, the loan is said to be in default, which can lead to penalties, collection efforts, or the loss of pledged assets.

Why Loans Matter to Investors

Loans are a central part of how the economy moves money from savers to borrowers. For investors, the most visible loans are those held by companies and governments. A company's borrowings appear as liabilities on its balance sheet, and the interest it pays reduces its profits. Analysts often compare debt levels with earnings and cash flow to judge how comfortably a company can meet its obligations. Loans can also be packaged and traded, as with some mortgage-backed securities, so their performance can affect bond markets and the broader financial system.
