Annual percentage rate (APR): What is it and how it works

Q: Can you compare APR between a fixed-rate loan and an ARM?

Not reliably. An ARM's APR is calculated using assumptions about future index movement that may not hold. Comparing a fixed-rate APR against an adjustable-rate APR mixes a known cost with a projected one. Compare fixed to fixed and ARM to ARM, and for ARMs focus on the initial rate, the caps, the margin and the index instead.

Borrower comparing two mortgage offers side by side at his kitchen table to weigh interest rate against APR

Your annual percentage rate (APR) is the yearly cost of a mortgage expressed as a percentage that folds your interest rate together with the charges you pay to get the loan, origination fees, discount points, mortgage broker compensation and mortgage insurance. Because it absorbs those upfront costs, APR is almost always higher than the note rate: on a $300,000 30-year loan at a 6.5% interest rate, one discount point plus $2,000 in lender fees leaves the monthly principal-and-interest payment at $1,896 but lifts the disclosed APR to roughly 6.66%.

APR is not a marketing number. Regulation Z sets the math in Appendix J and, as of August 2026, treats a disclosed APR as accurate on a regular transaction only within 1/8 of 1 percentage point of the true figure. It sits in the Comparisons box on page 3 of the Loan Estimate you receive within three business days of applying, described in wording the regulation dictates: “Your costs over the loan term expressed as a rate. This is not your interest rate.”

Here’s what APR includes and leaves out, how much points and fees move it, when a lower APR is genuinely the cheaper loan, and why you should never lay a fixed-rate APR next to an adjustable-rate one.

Key takeaways:

APR bundles your rate with the cost of getting the loan: Regulation Z folds origination fees, points, broker compensation and mortgage insurance into one yearly percentage, so a 6.5% loan carrying $5,000 in lender charges discloses an APR near 6.66%.
Your payment comes from the interest rate, never the APR: Two $300,000 loans at the same 6.5% rate both cost $1,896 a month even when one carries an APR 0.16 of a percentage point higher. The gap is $5,000 in fees, not a bigger payment.
APR assumes you keep the loan all 30 years: Paying one point to move a rate from 6.50% to 6.25% saves about $49 a month and takes roughly 61 months to break even, so the lower APR wins only if you stay past year five.

What’s the difference between APR and your interest rate?

The interest rate is the price of borrowing the money; the APR is that price plus the cost of getting the loan, restated as a single yearly rate. Your interest rate sets your payment. Your APR sets nothing. It is a comparison yardstick, and the Loan Estimate says so in those words.

The mechanics explain everything else on this page. To compute APR, the lender subtracts the prepaid finance charges from the loan amount to get the amount financed, then solves for the rate that makes your actual payments equal that smaller number. You make a $300,000 payment on what is functionally a $295,000 loan once $5,000 of charges come off the top, so the effective yearly cost lands above 6.5%.

That’s how two lenders quote an identical rate and cost thousands of dollars apart. For how the rate half of the equation gets set, see our How Rates Work explainer and the broader Mortgage Rates & Market guide. On the disclosure side, the CFPB on interest rate versus APR puts it plainly: APR reflects the interest rate, any points, mortgage broker fees and other charges you pay to get the loan, and “for that reason, your APR is usually higher than your interest rate.”

What’s included in APR, and what isn’t?

APR includes only what Regulation Z calls a finance charge: the cost of credit imposed by the creditor as a condition of the loan. That’s a narrower list than “closing costs,” which is exactly why a loan’s APR and its cash-to-close never match.

Generally included in APR:

Interest and prepaid interest: The note rate plus any per-diem interest collected at closing, which is why a loan with no lender fees can still disclose an APR slightly above its rate depending on your closing date.
Discount points and origination fees: Points, loan fees, assumption fees and similar charges are finance charges by name in the regulation.
Mortgage broker compensation: A finance charge even when the lender doesn’t require a broker and keeps none of the money.
Mortgage insurance: Premiums for any guarantee or insurance protecting the creditor against your default, private and government alike.

Generally excluded from APR:

Third-party real-estate fees, when bona fide and reasonable: Title examination, title insurance, survey, notary, credit report and document preparation sit outside the finance charge under 12 CFR 1026.4(c)(7).
The appraisal: Appraisal and property-condition inspection fees are excluded by that same provision, so what you pay an appraiser never shows up in your APR.
Escrow deposits: Money placed in escrow for taxes and insurance is your reserve, not a cost of credit.
Homeowners insurance: Excluded when you may choose the insurer and the condition is disclosed. A cost of owning, not of borrowing.

The consequence: a loan can carry the lowest APR on your desk and still cost the most at the closing table. Read the APR next to the itemized costs, not instead of them, our guide to mortgage closing costs walks the full list line by line.

How much do points and fees actually move your APR?

Roughly one-tenth of a percentage point of APR for every 1% of the loan amount you pay in finance charges on a 30-year loan. Here are two $300,000 offers at an identical 6.5% rate, one carrying $5,000 in lender charges and one carrying none.¹

30-year fixed, $300,000	Offer A	Offer B
Interest rate	6.50%	6.50%
Lender charges in the finance charge	$0	$5,000 (1 point + $2,000 in fees)
Monthly principal and interest	$1,896	$1,896
Disclosed APR	6.50%	About 6.66%
Paid in the first 5 years	$113,772	$118,772
Principal paid off in 5 years	$19,167	$19,167

Same rate, same payment, same balance after five years, and $5,000 more out of pocket. Nothing on the payment side of the form flags that gap. The APR does, and so does the “In 5 Years” line sitting directly above it in the same Comparisons box, which totals what you’ll have paid in principal, interest, mortgage insurance and loan costs by year five. That box is the most useful part of the form, and it’s the reason to know where APR appears on your Loan Estimate before you collect quotes.

When is the lower APR not the better deal?

When you won’t own the loan long enough to earn back the cash that bought the lower APR. APR is calculated over the full term, so it silently assumes you make all 360 payments, an assumption most borrowers break.

Take the same $300,000 loan. Paying one discount point, $3,000, to move the rate from 6.50% to 6.25% drops the payment from $1,896 to $1,847 and the APR from 6.50% to about 6.35%. The lower APR is real: held all 30 years, that loan pays roughly $17,700 less in interest. But the monthly saving is $49, so it takes about 61 months, a shade over five years, just to recover the $3,000. Sell or refinance in year four and the better APR was the worse decision.

CFPB guidance points the same direction: ask for the numbers “with and without points or credits” and price them over the shortest, longest and most likely time you’d hold the loan. How much rate a point buys is not fixed at a quarter point, it moves with the lender, the loan type and the market on the day you lock. Our guide to mortgage rate buydowns compares permanent points against temporary buydowns and where each breaks even.

Does APR change when mortgage rates move?

The rate half of your APR moves with the market every day until you lock; the fee half doesn’t move at all. Falling rates shrink the rate component but leave a lender’s origination fee at exactly the same dollar amount.

Be precise about what moves that rate component. The Federal Reserve sets the federal funds rate, an overnight bank-to-bank rate; it does not set mortgage rates. Long-term mortgage pricing tracks the 10-year Treasury yield and the spread investors demand on mortgage-backed securities, which is why mortgage rates sometimes rise on a day the Fed cuts. Our explainer on the Federal Reserve and mortgage rates walks that chain step by step.

Four APR myths worth unlearning

Four beliefs about APR account for most of the bad comparisons borrowers make.

Myth: APR is what your payment is based on. Reality: your principal and interest payment comes from the note rate, the loan amount and the term. Change the APR without changing those three and your payment doesn’t move a cent.
Myth: APR captures your total closing costs. Reality: appraisal, title, survey, notary, credit report and escrow deposits are excluded by regulation. Two loans with the same APR can differ by thousands at the table.
Myth: The lowest APR always wins. Reality: it wins over the full term. Over five years, the loan with the higher APR and lower upfront cash frequently costs less. A broker who runs both scenarios, one of the practical benefits of working with a mortgage broker, can show you the crossover month.
Myth: APR is only a shopping tool. Reality: it’s a legal trigger. Under 12 CFR 1026.35, a first-lien loan whose APR exceeds the average prime offer rate by 1.5 percentage points or more is a higher-priced mortgage loan, which carries mandatory escrow and appraisal requirements. The thresholds are 2.5 points on jumbo first liens and 3.5 points on subordinate liens.

How Align shops your rate

Your rate depends on you and on the lender. The same file can price differently from one wholesale lender to the next, which is why one application with Align goes to multiple lenders.

In late 2022, Freddie Mac found borrowers who got two quotes could have saved as much as $600 a year, and four or more quotes more than $1,200 a year.

Align is paid by the lender, not by a fee you pay us, and federal rules bar a broker's pay from changing with your rate or fees.

FAQ: APR on a mortgage

Here are answers to common questions about annual percentage rate.

Why is APR higher than the interest rate?

Because APR adds the cost of getting the loan to the cost of borrowing the money. Origination fees, points, broker compensation and mortgage insurance premiums get spread across the loan term and re-expressed as a rate. A loan with no points and no lender fees shows an APR nearly identical to its rate; one carrying heavy upfront costs shows a noticeably higher one. Mortgage insurance is often the largest single contributor, so read our guide to mortgage insurance alongside your quote.

Does APR affect my monthly mortgage payment?

No. Your principal and interest payment is calculated from the note rate, the loan amount and the term, nothing else. APR is a disclosure figure that expresses total borrowing cost, not a payment input. Use the payment to build your budget and use APR to compare two offers quoting the same rate with different fees. Our walkthrough of amortization schedules shows exactly which three inputs build the payment.

Should I choose the loan with the lower APR?

Usually, but not always. APR assumes you hold the loan for the full term, so a low APR bought with discount points only wins if you stay long enough to recover the cash on a $300,000 loan, paying one point to save $49 a month takes about 61 months. If you expect to move or refinance inside five years, compare total cash paid over five years instead. Our guide to mortgage rate buydowns runs that math.

Can you compare APR between a fixed-rate loan and an ARM?

Not reliably. An adjustable-rate loan’s APR is built on the index value at closing with no assumption that the rate rises, so it does not reflect the loan’s maximum interest rate, a caution the CFPB gives directly. Comparing a fixed APR to an ARM APR mixes a known cost with a projected one. Compare fixed to fixed and ARM to ARM, judging ARMs on the initial rate, caps, margin and index, as our fixed vs. adjustable-rate mortgage comparison explains.

The bottom line on APR

APR is the yearly cost of your mortgage with the financed cost of obtaining it folded in, computed under Regulation Z and disclosed on page 3 of every Loan Estimate within 1/8 of 1 percentage point of the true figure. It answers a different question than your interest rate: the rate sets your $1,896 payment, while the APR tells you the same 6.5% loan carrying $5,000 in lender charges really costs about 6.66% a year. Use APR to compare offers at the same rate, use five-year totals when you won’t keep the loan 30 years, and never compare a fixed-rate APR against an ARM’s.
