What’s the Difference Between Interest Rate and APR?

The question: What is the difference between interest rate and APR on a mortgage, and which number should you trust when two Loan Estimates point different ways?

The short answer: The interest rate sets your monthly principal and interest payment. The annual percentage rate (APR) adds most of the lender’s charges, such as points, origination fees and mortgage insurance, and expresses the total as one yearly rate over the full loan term. So APR is the better tool for comparing offers of the same loan type and term. However, it assumes you keep the loan its full term, so it can mislead if you sell or refinance early.

How are the interest rate and APR different on a mortgage?

The interest rate is the yearly cost of borrowing the money itself. The Consumer Financial Protection Bureau (CFPB) notes that it “does not reflect fees or any other charges.” The rate, loan amount and term set the monthly principal and interest payment.

The APR measures the cost of credit as a yearly rate. Under federal Regulation Z, it relates the money you receive, and when, to the payments you make, and when (12 CFR 1026.22(a)(1)). In practice, it starts with the interest rate and adds the other finance charges, the costs of credit beyond the interest. Charges paid at closing mean you effectively receive less than the loan amount. Meanwhile, monthly charges such as mortgage insurance add to what you pay. As a result, the APR is usually higher than the rate.

Every lender must calculate the APR under the same federal rules. So a mortgage APR shows which offer of the same loan type and term costs more once lender fees count.

What goes into the APR, and what stays out?

Regulation Z defines the finance charge as any charge the borrower pays, directly or indirectly, that the lender imposes as a condition of, or an incident to, the loan (12 CFR 1026.4(a)). Here is how common mortgage costs sort out:

The first five items on the right stay out only if they are “bona fide and reasonable in amount.” Recording fees and mortgage taxes stay out only if they are itemized and disclosed. Also, a lender that keeps part of a third-party fee must count that part.

So APR captures the main costs a lender sets or passes through: points, the loan origination fee, broker pay and mortgage insurance. Much of the title and settlement bill stays outside it, though. Our guide to home loan closing costs covers those fees.

A worked example: two offers that point different ways

The CFPB publishes an example of how points and lender credits trade against the rate. Say you borrow $180,000 on a 30-year fixed-rate loan at a zero-point rate of 5.000%. These are the CFPB’s example rates, not today’s rates. Monthly figures cover principal and interest only, with no taxes, homeowners insurance or mortgage insurance.

Between the two offers, the gap is $1,350 at closing ($675 paid plus $675 received). Monthly, it is about $28 ($13.70 plus $13.80, which the CFPB rounds to $14 each).

Which one wins depends on how long you keep the loan

Over the full 30-year term, Offer A saves about $27.50 a month (the CFPB rounds each side to $14) for 360 months. That comes to about $9,900, for $1,350 more at closing. APR math assumes you keep the loan that long. Therefore, Offer A would usually show the lower APR even though it costs more on day one.

Now divide the extra cash by the monthly saving: $1,350 ÷ $27.50 is about 49 months, or a little over four years, counting payments alone. However, the lower rate also pays down slightly more principal, so the true break-even is somewhat sooner, a bit over three years here. If you expect to sell or refinance sooner than that, Offer B costs less despite its higher APR. Our guide to mortgage discount points covers this break-even test.

The same logic applies when two lenders disagree. If one Loan Estimate has the lower rate and the other the lower APR, the lower-rate offer is carrying more of the costs that count in the APR, usually points and lender fees paid at closing. Check Section A on page 2 for origination charges and points, and Section J for lender credits.

Where do you find the rate and APR on your Loan Estimate?

The Loan Estimate puts the two numbers on different pages (12 CFR 1026.37):

• Interest rate: page 1, under “Loan Terms,” next to the monthly principal and interest payment.
• APR: page 3, under “Comparisons,” labeled “Your costs over the loan term expressed as a rate.”
• “In 5 Years”: also on page 3, the principal, interest, mortgage insurance and loan costs paid after 60 months.
• Total Interest Percentage (TIP): total interest over the term as a percentage of the loan amount.

The CFPB’s Loan Estimate explainer walks through each page. For two competing offers, “In 5 Years” is a useful companion to APR because it shows what each offer costs over a shorter period.

What changes on the Closing Disclosure

The Closing Disclosure repeats the APR and TIP in its “Loan Calculations” table. You must receive it at least three business days before closing (1026.19(f)(1)(ii)).

The disclosed APR has a tolerance: 1/8 of a percentage point for a regular loan, and 1/4 point for an irregular one, such as a loan with uneven payments (1026.22(a)(2)–(3)). If the APR moves beyond that tolerance before closing, the lender must give you a corrected Closing Disclosure. Then a new three-business-day wait begins (1026.19(f)(2)(ii)).

For example, say the Closing Disclosure shows a 7.00% APR on a regular loan. If the APR at closing will be 7.10%, closing goes ahead with corrected figures. At 7.15%, however, the lender must delay. An APR that falls because your costs fell generally counts as accurate, so a rising APR is what triggers the delay (1026.22(a)(4), 1026.38(o)(2)).

When does the APR mislead?

APR rests on fixed assumptions, and these cases break them.

You sell or refinance within a few years

The APR spreads upfront costs over the full term, often 360 months. If you move or refinance well before then, a high-points offer looks better on APR than it performs. For a short holding period, compare the “In 5 Years” totals instead.

Adjustable-rate mortgages

For an ARM mortgage with a discounted start rate, the APR blends the start rate with the fully indexed rate at closing (index plus margin). It does not assume the index will rise (Regulation Z comments 17(c)(1)-8 and -10). As the CFPB warns, an ARM’s APR “does not reflect the maximum interest rate of the loan.” So don’t use APR alone to choose between an ARM and a fixed rate.

Different loan types

Mortgage insurance counts in the APR only for as long as the lender requires it (Regulation Z comment 4(b)(5)-1). So APRs across programs with different insurance structures don’t compare cleanly:

• FHA loans charge a 1.75% upfront premium plus an annual premium. In 2026, with a base loan of $726,200 or less and a term over 15 years, the annual premium is 0.55% above 95% loan-to-value (LTV) and 0.50% at or below it (HUD Handbook 4000.1, Appendix 1.0, from Mortgagee Letter 2023-05). Above 90% LTV, it lasts the full term, which lifts the APR.
• VA loans have no monthly mortgage insurance. However, unless exempt (for example, a veteran who receives VA disability compensation), a borrower pays an upfront funding fee: 2.15% in 2026 for a first-use purchase with less than 5% down.

So compare APRs within one program, not across programs. Similarly, a HELOC’s APR excludes fees, according to the CFPB, so don’t set it against a cash-out refinance APR.

Can the APR be lower than the interest rate?

Usually it isn’t, because the charges that count toward the APR only add to its cost. A lender credit works the other way. It lowers what you pay at closing in exchange for a higher interest rate, and that higher rate still means a higher payment every month. If an offer ever shows an APR below its interest rate, ask the lender which charges and credits it counted.

How to use APR vs interest rate when shopping

APR comparisons work only when the offers are built the same way. Before you compare, line up these details:

1. Quote date. Rates move daily, so get every quote on the same day.
2. Loan type and term. Compare a 30-year fixed with a 30-year fixed, and FHA with FHA.
3. Rate lock period. Ask what a shorter or longer lock costs.
4. Points or credits. The CFPB suggests asking each lender for the same amount.
5. All three measures. The rate sets the payment, while the APR shows full-term cost and “In 5 Years” a shorter horizon.

FAQ

Is APR or interest rate more important?

They answer different questions. The rate sets your monthly principal and interest payment. The APR shows which same-type offer costs less over the full term, so use both.

Why is my APR higher than my interest rate?

Your APR adds the other finance charges: points, origination and broker fees, prepaid interest and required mortgage insurance. Charges paid at closing shrink the money you effectively receive, and monthly charges add to your payments. So the loan’s yearly cost lands above the note rate.

Can APR be lower than the interest rate?

Not from fees, because the charges that count toward the APR only add to it. A lender credit lowers your closing costs but comes with a higher rate and payment. If an offer shows an APR below its rate, ask the lender which charges and credits it counted.

Does APR include mortgage insurance?

Yes, for the period the lender requires it. Private mortgage insurance and FHA premiums both count as finance charges. Homeowners insurance generally doesn’t, as long as you can choose your insurer.

Is a lower APR always better?

No. A lower APR often reflects paid points, which pay off only after the break-even point. If you may move or refinance within a few years, a higher-APR offer with lower upfront costs can cost less.

What is a good APR on a mortgage?

No single APR is “good,” since it depends on your credit, down payment, loan type and costs. For context, the Freddie Mac Primary Mortgage Market Survey put the average 30-year fixed rate at 7.18% on November 5, 2026, up from 6.22% a year earlier. That figure is an interest rate, not an APR. Instead, judge how far each offer’s APR sits above its rate, and compare quotes for the same loan.

What to do with your two Loan Estimates

Put both Loan Estimates side by side and confirm they match on loan type, term, lock period and quote date. Then compare the rates, APRs and “In 5 Years” totals. If the lower-rate offer has the higher APR, divide its extra upfront cost by its monthly saving to see how long you must keep the loan.

If the offers still don’t line up, ask each lender to requote with the same points or credits.
