What APR really tells you

APR folds upfront fees into a single yearly rate, so two loans can be compared fairly.

The interest rate (or "note rate") on a loan only describes the cost of the money you borrow. APR — annual percentage rate — goes further by including upfront fees, points, and other charges, expressed as a single yearly rate. That makes APR the best apples-to-apples way to compare loan offers.

How APR is calculated

APR is the interest rate that makes the present value of all your payments equal to the amount you actually receive after fees. Because fees are paid up front but spread across the loan's life, a loan with fees always has an APR higher than its note rate. This calculator solves for that rate numerically.

Tip: APR assumes you keep the loan for its full term. If you'll pay off or refinance early, fees are spread over fewer years, so your effective rate is even higher than the quoted APR.

APR vs note rate when shopping

Two loans can advertise the same interest rate but have very different APRs once fees are counted. Lenders are legally required to disclose APR, so use it — not the headline rate — when comparing mortgages, auto loans, and personal loans.

Frequently asked questions

What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal. APR adds in fees, points, and certain closing costs, expressed as an annual rate. APR is always equal to or higher than the interest rate and is the better number for comparing loans.
Why is my APR higher than my interest rate?
Because fees paid up front are spread across the loan term and counted as part of the cost. The more fees you pay relative to the loan amount, the larger the gap between your note rate and your APR.
Does a lower APR always mean a better loan?
Usually, but not always. APR assumes you keep the loan for the full term. If you plan to sell or refinance soon, a loan with a higher APR but lower fees might cost you less, because you won't be around long enough to benefit from the lower rate.
Are all fees included in APR?
Lenders must include most finance charges — origination fees, points, and some closing costs — but rules vary by loan type and some third-party costs are excluded. Always ask for an itemized fee list in addition to the APR.
How accurate is this APR estimate?
It uses the same present-value method lenders use and is accurate for fixed-rate loans. Real disclosures may differ slightly depending on which specific fees a lender includes under the law.
