A personal loan is an unsecured installment loan: you borrow a fixed amount and repay it in equal monthly payments over a set term, typically two to seven years. Because it's unsecured — not backed by a house or car — rates are higher than a mortgage or auto loan but usually far lower than a credit card, which makes personal loans a common tool for consolidating high-interest debt.
Two numbers determine the cost: the APR and any origination fee. The origination fee, often 1–8%, is deducted from the amount you receive, so on a $15,000 loan with a 3% fee you'd get $14,550 but repay the full $15,000 plus interest. That's why the effective cost is higher than the note rate, and why comparing by APR and total cost matters.
