APR vs. Interest Rate: What's the Difference on a Mortgage?
In this article
Your interest rate is what the lender charges each year just to borrow the money. Your APR (annual percentage rate) is a bigger number that adds in points, lender fees and some other loan costs, so it shows more of what the loan really costs. The Consumer Financial Protection Bureau (CFPB) says that is why your APR is usually higher than your interest rate.
When you compare two mortgage offers, look at both numbers side by side. The gap between them tells you how much you are paying in upfront loan costs.
What is the difference between APR and interest rate?
Think of the interest rate as the price tag on the money itself. It sets your monthly principal and interest payment.
The APR is a wider measure. The CFPB explains it this way: ""The APR reflects the interest rate, any points, mortgage broker fees, and other charges that you pay to get the loan.""
Here is the simple version:
Interest rate: the yearly cost of borrowing, shown as a percent. It does not include fees.
APR: the interest rate plus certain loan costs, spread over the life of the loan and shown as one yearly percent.
If a loan has almost no fees, the APR and the rate will be very close. If a loan has big fees or points, the APR will be noticeably higher than the rate.
Where do I find the APR on my Loan Estimate?
Every lender has to give you the same three-page form, called a Loan Estimate, after you apply. According to the CFPB, you can find the interest rate on page 1 under ""Loan Terms,"" and the APR on page 3 under ""Comparisons.""
Page 3 also has a line called ""In 5 Years."" The CFPB says the first number there is the total you will pay over five years, including principal. That line is handy if you think you might sell or refinance within a few years.
What costs are included in the APR, and what is left out?
Federal rules decide what goes into the APR. Under Regulation Z, the ""finance charge"" is ""the cost of consumer credit as a dollar amount."" Costs that count as part of the finance charge raise your APR.
Things that usually push the APR up:
Discount points you pay to get a lower rate
Lender origination or underwriting fees
Mortgage broker fees
Some real estate costs are left out, as long as they are ""bona fide and reasonable in amount."" The rule (12 CFR 1026.4(c)(7)) lists fees for title examination and title insurance, document preparation, notary and credit-report fees, and appraisal or inspection fees done before closing.
So the APR is a better measure of cost than the rate alone, but it is not every dollar you will pay at closing. Your total closing costs are a separate line on the Loan Estimate.
How much can points change the APR? An example
Here is a side-by-side look at two offers on the same loan. This is an EXAMPLE with made-up pricing, not a quote. Real offers change daily. For reference, the 30-year fixed averaged 7.40% in Freddie Mac's weekly survey as of Oct. 8, 2026, so Offer A uses that rate.
EXAMPLE: $360,000 loan, 30-year fixed
Offer A | Offer B | |
|---|---|---|
Interest rate | 7.40% | 7.00% |
Points paid | none | 1.5 points ($5,400) |
Other lender fees in the APR | $3,000 | $3,000 |
Monthly principal and interest | $2,492.57 | $2,395.09 |
APR (calculated) | 7.485% | 7.236% |
Offer B has the lower APR and a payment that is $97.48 lower each month. But you pay $5,400 more up front for those points.
How long until the lower payment pays back the points? Divide $5,400 by $97.48 and you get about 55 months, or a little over four and a half years.
This is where buyers get tripped up. The APR spreads the upfront costs over the full 30-year term. If you sell or refinance before the break-even point, Offer A may actually cost you less, even though its APR is higher.
Is a lower APR always the better deal?
Not always. The CFPB warns, ""Don't look at the APR alone in determining what loan makes the most sense for your circumstances.""
A lower APR is usually a good sign when:
You plan to keep the loan for many years
You are comparing the same loan type (for example, two 30-year fixed loans)
The Loan Estimates were issued close to the same day
Be more careful when:
You may move or refinance soon. Points take years to pay back.
You are comparing fixed to adjustable. The CFPB says that for adjustable-rate mortgages, ""the APR does not reflect the maximum interest rate of the loan."" It also says to ""be careful when comparing the APRs of fixed-rate loans with the APRs of adjustable-rate loans.""
The offers came on different days. The CFPB notes that ""interest rates can change daily,"" so a rate gap can come from market moves, not a better lender.
Can my APR change before closing?
Yes, it can. Your final numbers show up on the Closing Disclosure, which you must receive at least three business days before you close (12 CFR 1026.19(f)).
If the APR changes by more than the allowed amount, the lender has to give you corrected disclosures, and a new three-business-day waiting period starts. For most fixed-rate loans, the APR is considered accurate if it is within 1/8 of 1 percentage point of the correct figure (12 CFR 1026.22). For ""irregular"" loans, the limit is 1/4 of 1 percentage point.
A change bigger than that can push your closing date back. That matters a lot when you are buying a new home with a set move-in date.
What this means for new-construction buyers
Buying a brand-new home adds a few twists to the APR story.
Builder-paid points. Many builders offer to pay toward points or closing costs. Under Regulation Z, ""seller's points"" are left out of the finance charge (12 CFR 1026.4(c)(5)). Ask your lender to show you exactly how any builder credit appears on your Loan Estimate, so you are comparing offers the same way.
Builder lender vs. your own lender. If a builder's preferred lender offers an incentive, get a Loan Estimate from at least one other lender too. The CFPB says your ""best bargaining chip is usually having Loan Estimates from other lenders in hand."" Compare the rate, the APR, the points and the ""In 5 Years"" line.
Long build times. A new home can take months to finish. If your rate lock runs out and you relock at a different rate, your APR changes too. Plan your lock around the build schedule.
Temporary buydowns. A 2-1 buydown lowers your payment for the first two years only. Ask your lender how it shows up on your disclosures, and make sure you can afford the full payment that starts later.
Common Questions
Is APR or interest rate more important when buying a house?
Both matter. The interest rate sets your monthly payment, and the APR shows the cost of the loan once points and lender fees are added in. Use the APR to compare offers for the same loan type, then check the upfront costs and how long you plan to keep the loan.
Why is my APR higher than my interest rate?
Your APR includes points, lender fees and some other charges you pay to get the loan, while the interest rate does not. The CFPB says that is why the APR is usually higher. A big gap between the two means you are paying more in upfront loan costs.
Where is the APR on a Loan Estimate?
The CFPB says the interest rate is on page 1 under ""Loan Terms,"" and the APR is on page 3 under ""Comparisons."" Page 3 also shows the ""In 5 Years"" line, which is helpful if you might sell or refinance within a few years.
Does the APR include closing costs?
It includes some of them, like points and lender fees, but not all. Federal rules leave out fees such as title insurance, appraisal, credit report and notary fees when they are reasonable. Check the closing costs section of your Loan Estimate for the full picture.
Can my APR change after I get my Loan Estimate?
Yes. If the APR on your Closing Disclosure changes by more than the allowed amount, your lender must give you corrected disclosures and a new three-business-day waiting period begins. For most fixed-rate loans, that limit is 1/8 of 1 percentage point.
Should I pick the loan with the lowest APR?
Often, but not always. The APR assumes you keep the loan for its full term, so a low-APR offer with expensive points may cost more if you sell or refinance early. Work out how many months it takes for the lower payment to pay back the points.
