APR vs Interest RatesAn APR is an annual cost you’ll pay on a loan including the origination fee. An interest rate is the cost of borrowing the principal loan amount and can be variable or fixed depending on the type of the loan. While both are expressed as percentage rates, the APR is the true cost of credit and includes applicable fees. Personal Loan APRWith a personal loan, the APR is a rate of interest expressed as a yearly percentage for the duration of the loan including the origination fee. A personal loan APR is fixed which means your interest rate won’t change over the term of the loan, and you pay the loan back in equal, monthly installments. This differs from credit card issuers that calculate APR using an index rate such as the prime rate, which can be variable or the London Interbank Offered Rate (LIBOR). A variable interest rate on a credit card could cause your interest rate to change — making your monthly payment harder to predict.
