APR vs. Interest Rate: What's the Difference?
October 20, 2026
The interest rate is what you pay each year to borrow the principal, and it sets your monthly principal-and-interest payment. The APR (annual percentage rate) is a broader yearly cost that combines the interest rate with most lender charges, such as points, origination fees and mortgage insurance. APR is usually higher than the interest rate, and the bigger the gap between the two, the more fees are built into the loan. On a Loan Estimate, the interest rate is on page 1 under Loan Terms and the APR is on page 3 under Comparisons.
What each number includes. The interest rate covers only the cost of borrowing the principal. It doesn't include points, lender fees or third-party costs, and it's the number that drives your monthly principal-and-interest payment. APR spreads certain finance charges over the life of the loan and states the result as a yearly rate. Under Regulation Z, finance charges on a mortgage typically include interest, discount points, origination charges, mortgage broker fees, mortgage insurance premiums and certain other lender-required charges. Some costs are excluded for loans secured by real estate, including title fees, appraisal and credit report fees, and taxes and government recording fees. So APR doesn't capture every closing cost. Use the interest rate to budget your payment, and use APR to compare the overall cost of offers.
When APR can mislead. APR assumes you keep the loan for its full term. If you expect to sell or refinance within a few years, upfront fees cost more per year than the APR shows, so also look at the In 5 Years row on page 3. On an adjustable-rate mortgage, APR relies on assumptions about future rates, and your actual cost may differ. And APR comparisons only work for the same loan amount, term, loan type and lock date. A smaller APR isn't automatically the right choice either. It can come from fewer upfront fees or from a smaller rate, and which matters more depends on how long you'll keep the loan and how much cash you have for closing. Check Section A for origination charges and points, Section J for lender credits, and the In 5 Years totals. APR can also change before closing. If the APR on your Closing Disclosure rises beyond a small tolerance (generally more than one-eighth of a percentage point on most fixed-rate loans), the lender must give you a corrected disclosure and a new three-business-day waiting period.
Quick answers. Why is APR higher than the rate? Because it adds lender finance charges such as points, origination fees and mortgage insurance to the interest cost. Can APR be lower than the rate? It's uncommon, but it can happen, for example when a lender credit covers finance charges. Is APR the same as the Total Interest Percentage (TIP)? No. TIP is the total interest you'd pay over the term as a percentage of the loan amount, while APR is a yearly rate that includes fees. Do ads have to show APR? Under Regulation Z, an ad that states a rate of finance charge must also state the APR, at least as prominently. Which number should you negotiate? Both. Ask for the rate you want and an itemized list of the points and fees you'd pay at that rate, then compare the full Loan Estimates.
The interest rate sets your monthly principal and interest. APR adds most lender finance charges to show a yearly cost, which makes it a useful, but not complete, comparison tool. Compare both numbers, plus Sections A and J and the In 5 Years totals, on same-day offers for the same loan.
