Interest Rate vs APR

The interest rate (note rate) determines your monthly payment, but it ignores fees. The APR rolls origination fees, points, and closing costs into a single annualized rate so you can compare loans fairly. Because you pay the same monthly payment but receive less cash (loan minus fees), your effective borrowing cost — the APR — is higher than the note rate. Federal Truth in Lending law requires lenders to disclose APR for exactly this reason.

For example, a $250,000 loan at a 6.5% note rate over 30 years has a payment of about $1,580. With $5,000 in fees, you effectively borrowed only $245,000 but still pay as if you borrowed $250,000 — pushing the APR to about 6.69%. When shopping lenders, compare APRs, not just rates: a lower rate with high fees can have a higher APR than a slightly higher rate with none.

Note Rate

The stated interest rate that sets your monthly payment. It excludes fees, so it understates the true cost.

APR

The all-in annualized cost including fees. Always higher than the note rate when fees exist. Use it to compare offers.

A 6.25% rate with $8,000 fees may cost more than 6.5% with none. The APR reveals which loan is actually cheaper.

FAQ

The interest rate sets your monthly payment based on the loan balance. The APR adds in fees and closing costs and expresses the total as one annual rate. APR is always equal to or higher than the note rate, and it's the better number for comparing loan offers.
First compute the monthly payment using the note rate and full loan amount. Then find the rate that makes the present value of those payments equal to the net amount you actually receive (loan minus fees). That solved rate, annualized, is the APR. This calculator solves it iteratively for you.
Because you pay fees to get the loan, you effectively borrow less than the loan amount but make payments as if you borrowed the full amount. That gap raises your true annual cost above the note rate. With zero fees, the APR equals the interest rate.
