APR vs nominal interest rate
The nominal interest rate is the stated rate applied to your balance. APR extends that by adding certain required financing costs, giving a more realistic borrowing metric. Two loans with the same nominal rate can have different APR values if fees differ.
That is why APR is commonly used in consumer finance comparisons. It helps reduce confusion created by low advertised rates paired with large origination or processing charges.
Using APR for better loan comparisons
Compare offers using the same loan amount and term assumptions. A lower APR generally indicates a cheaper loan, but also review flexibility terms such as prepayment policy, late fees, and rate reset clauses.
