APR vs Interest Rate on a Personal Loan

Quick answer: The interest rate describes the rate charged on the loan balance; APR can also reflect required fees. A loan with a fee can have an APR higher than its interest rate. Compare both figures with payment, term, and the cash you actually receive.

How can the same interest rate produce different APRs?

Suppose two hypothetical loans both have a $10,000 balance, a 15% annual interest rate, and 36 monthly payments of $346.65. One has no origination fee; the other deducts a $500 required fee from the proceeds. The payment on the balance is unchanged, but the second borrower receives less money.

How is the fee-adjusted APR example calculated?

The estimate solves for the monthly rate that makes the present value of 36 equal payments match the $9,500 received, then multiplies that monthly rate by 12. It assumes equal monthly periods and no other fees. This simplified cash-flow estimate is not a substitute for the lender’s regulated APR disclosure.

Which number belongs in a monthly payment formula?

A contractual interest-rate amortization uses the periodic interest rate on the balance. An APR that includes separate fees should not automatically be substituted for that rate. BYL’s fee-free comparison tables explicitly assume APR equals the annual interest rate.

What should you compare next?

Check both the interest rate and APR, then review the fee, cash received, term, payment, and total repayment.
