The annual percentage rate (APR) on a mortgage represents the total yearly cost of borrowing, expressed as a percentage that includes not just the interest you pay on the loan balance but also the fees and charges that come with getting the loan. Your APR will almost always be higher than your interest rate because it rolls in costs like origination fees, discount points, and mortgage insurance premiums. For a typical 30-year fixed mortgage, the spread between the two might be small, sometimes just a fraction of a percentage point, but over a 30-year repayment period that gap can translate into thousands of dollars.
Interest Rate vs. APR
Your interest rate is the cost of borrowing the principal balance each year, nothing more. If you borrow $300,000 at a 6.13% interest rate, that percentage determines how much interest accrues on your balance every month. It does not account for the lender fees, broker charges, or insurance premiums you paid to secure that loan.
The APR folds those extra costs into a single number so you can compare the true price of one loan against another. The Consumer Financial Protection Bureau describes it as “a broader measure of the cost of borrowing money than the interest rate.” On a Loan Estimate, which every lender must provide after you apply, you’ll find the interest rate on page 1 under “Loan Terms” and the APR on page 3 under “Comparisons.” That placement is deliberate: the APR exists specifically to help you compare offers side by side.
As a real-world reference point, NerdWallet’s rate survey in late April 2026 showed the average 30-year fixed mortgage carrying a 6.13% interest rate alongside a 6.15% APR. That narrow 0.02 percentage point gap suggests relatively modest upfront fees on the average loan. But individual offers can vary widely depending on the lender, the loan program, and how many upfront fees are baked in.
What Fees Are Included in the APR
Federal lending rules require lenders to count specific charges as “finance charges” when calculating the APR. The major ones you’ll encounter on most mortgage transactions include:
- Origination fee: the lender’s charge for processing and creating the loan, often 0.5% to 1% of the loan amount.
- Discount points: optional upfront payments to lower your interest rate. One point equals 1% of the loan amount, so one point on a $400,000 loan costs $4,000.
- Broker fee: compensation paid to a mortgage broker if one arranged the loan on your behalf.
- Underwriting and processing fees: charges for evaluating your creditworthiness and preparing the file for approval.
- Mortgage insurance premiums (MIP) or funding fees: upfront insurance charges on FHA loans, VA funding fees, and USDA guarantee fees all get folded into the APR.
- Other required charges: flood certification fees, tax service fees, wire and courier fees, escrow waiver fees, and MERS registration fees.
Some costs are specifically excluded. Homeowner’s insurance and flood insurance premiums can be left out of the APR calculation as long as the lender discloses that you’re free to shop for coverage from any provider you choose. Similarly, optional insurance products like credit life insurance or disability coverage stay out of the APR as long as the lender tells you in writing that the coverage isn’t required and you affirmatively request it. Title insurance, recording fees, and appraisal charges are also generally excluded.
The result is that the APR captures most lender-side costs but not every dollar you’ll spend at closing. You can still face expenses like the appraisal, a home inspection, or prepaid property taxes that don’t appear in the APR figure.
How Discount Points Affect the APR
Discount points are one of the biggest reasons two loan offers from the same lender can show very different APR and interest rate combinations. When you pay points upfront, your interest rate drops, which lowers your monthly payment for the life of the loan. But because the points themselves are a finance charge, they push your APR higher relative to the reduced interest rate.
Consider two offers on a $350,000 loan. Offer A has a 6.25% rate with zero points. Offer B has a 5.875% rate but costs two points ($7,000 upfront). Offer B gives you a lower monthly payment, but the APR on Offer B might actually be higher than Offer A’s APR if you only keep the loan for a few years, because you’re spreading that $7,000 cost over a short period. If you hold the loan for 10 or 15 years, the monthly savings add up and the effective cost drops well below the zero-point option.
The CFPB recommends asking your loan officer to run the numbers across at least three timeframes: the shortest time you might keep the loan, the longest, and the most likely. That comparison shows you the break-even point, the moment when the savings from the lower rate finally recoup what you paid in points.
Using the APR to Compare Loan Offers
The APR is most useful when you’re comparing loans of the same type and the same term. Two 30-year fixed-rate offers are easy to stack up by APR: the lower APR generally means the lower total cost over the full loan term. But comparing a 30-year fixed APR against a 15-year fixed APR is misleading because the shorter loan has a different repayment structure and a different total interest cost regardless of fees.
Adjustable-rate mortgages (ARMs) complicate things further. An ARM’s APR is calculated using the initial rate for the fixed period and then projections based on the rate index and caps built into the loan. Those projections may not reflect what actually happens to rates in the future, so the APR on an ARM is more of an estimate than a guarantee. When comparing an ARM to a fixed-rate loan, pay attention to the initial rate, the adjustment caps, and the worst-case monthly payment, not just the APR.
When two loans are truly comparable, though, even small APR differences matter over time. On a $350,000 loan, the difference between a 6.15% APR and a 6.40% APR works out to roughly $60 more per month, or about $21,600 over a 30-year term. That’s why the APR exists: to surface cost differences that the interest rate alone would hide.
Limits of the APR
The APR assumes you’ll keep the loan for its full term. If you sell the house or refinance after five or seven years, the upfront costs that were spread across 30 years in the APR calculation actually hit your wallet much harder on a per-year basis. A loan with higher closing costs but a slightly lower rate might look better by APR, yet cost you more if you move before the break-even point.
The APR also doesn’t capture every closing cost. Appraisal fees, title search charges, recording fees, and prepaid expenses like homeowner’s insurance or property tax escrow sit outside the calculation. Two loans with the same APR could still have different total cash-to-close figures. Always review the full Loan Estimate, not just the APR line, before choosing a lender.
