Interest Rate Defined
The interest rate is the percentage charged on the principal balance. On a $300,000 mortgage at 6.5%, you pay interest on the outstanding balance each month.
The rate alone does not include origination fees, points, or mortgage insurance.
APR Defined
APR (Annual Percentage Rate) spreads fees over the loan term and expresses total borrowing cost as a yearly rate. A 6.5% rate with $5,000 in fees might have a 6.8% APR.
For credit cards, APR is the yearly rate applied to carried balances. See our mortgage comparison guide for home loans.
Which to Use When
Loans: compare APR across lenders on the same day. Credit cards: know your APR but aim to pay in full monthly.
