Last reviewed: November 2026 · Educational information, not financial advice.

Key points

  • With an installment loan you get a lump sum and repay it in fixed amounts, called installments, over a set period.
  • Terms can range from a few months to several years, and amounts from a few hundred to several thousand dollars or more.
  • Check whether the rate is fixed or adjustable, the APR, and every fee before you sign.
  • Add-on products such as credit insurance are generally optional. You can say no.

How installment loans work

A personal installment loan gives you money up front that you repay in equal scheduled payments until the loan is paid off. Each payment covers part of the amount you borrowed plus interest. Because the payment usually stays the same, it is easier to budget for than a balance that changes from month to month.

Lenders typically look at your credit reports and scores, income, existing debts, and the amount and length of the loan. State laws also limit the rates some lenders can charge, so offers can differ from state to state.

Fees to ask about

Fee or productWhat it is
Origination feeA fee for making the loan, which adds to the total cost and may be deducted from the amount you receive.
Documentation feeA charge to process the loan paperwork.
Late feeCharged when a payment is late.
Credit or disability insuranceAdd-on coverage that is generally optional. It increases what you pay.

Short-term loans: be careful

Some lenders offer short-term loans with very high APRs. Short-term loans are not a long-term financial solution. Before you borrow, compare the APR and the total amount you will repay, and make sure the payments fit your budget for the whole term. If a payment would be hard to make, talk to the lender before the due date, or contact a nonprofit credit counselor.
