A payday loan (also called a payday advance, salary loan, payroll loan, small dollar loan, short term, or cash advance loan) is a small, short-term unsecured loan, "regardless of whether repayment of loans is linked to a borrower's payday." The loans are also sometimes referred to as "cash advances," though that term can also refer to cash provided against a prearranged line of credit such as a credit card. Payday advance loans rely on the consumer having previous payroll and employment records. Legislation regarding payday loans varies widely between different countries, and in federal systems, between different states or provinces.
In calculating finance charges under this subsection, when the first installment period is longer than the remaining installment periods, the amount of the finance charges applicable to the extra days shall not be greater than $15.50 per $100 of the original principal balance divided by the number of days in a regularly scheduled installment period and multiplied by the number of extra days determined by subtracting the number of days in a regularly scheduled installment period from the number of days in the first installment period.
To prevent usury (unreasonable and excessive rates of interest), some jurisdictions limit the annual percentage rate (APR) that any lender, including payday lenders, can charge. Some jurisdictions outlaw payday lending entirely, and some have very few restrictions on payday lenders. In the United States, the rates of these loans were formerly restricted in most states by the Uniform Small Loan Laws (USLL), with 36%-40% APR generally the norm.
