APR vs Interest Rate: What’s the Difference and Which Matters?
The interest rate is the menu price; the APR is closer to the final bill. Here is what APR includes, why it is higher, and how to use it to compare mortgage offers.
- Interest rate: The yearly cost of borrowing the money itself. It sets your monthly principal and interest payment.
- APR: The interest rate plus many of the lender’s upfront charges (like points and origination fees), shown as a yearly rate.
- Why APR is higher: It spreads those extra costs over the loan, so it is almost always above the interest rate.
- How to use it: Compare APRs on loans with the same type and term, and look at how long you plan to keep the loan.
- Points: Paying points lowers your rate but raises your upfront cost. The APR helps show whether that trade is worth it.
You get two mortgage quotes. One says 7.125%. The other says 7.375%. Easy choice, right? Then you spot a second number on each one: the APR. Suddenly the cheaper-looking loan might not be the cheaper loan.
Interest rate vs APR is like the menu price vs the final bill at a restaurant. The menu price is what you notice. The final bill, with the service fee and that “small” bread basket charge, is what you actually pay.
What is the interest rate?
Your interest rate is the percentage the lender charges you each year to borrow the money. It is the number used to calculate your monthly principal and interest payment.
It does not include any of the fees you pay to get the loan. Two lenders could offer the same rate but charge very different upfront costs. That is where APR helps.

What is APR?
APR stands for annual percentage rate. It is a broader measure of what the loan costs you per year. Federal law requires lenders to show it, so you can compare offers in a more apples-to-apples way.
APR rolls the interest rate together with certain upfront costs, then expresses the total as a yearly rate over the life of the loan.
What APR includes (and what it doesn’t)
| Usually included in APR | Usually not included in APR |
|---|---|
| Interest rate | Appraisal fee |
| Discount points | Title insurance and title fees |
| Origination and underwriting fees | Credit report fee |
| Mortgage broker fees | Homeowners insurance |
| Mortgage insurance premiums (PMI or MIP) | Property taxes and escrow deposits |
| Prepaid interest | Recording fees and transfer taxes |
The exact list follows federal rules under the Truth in Lending Act, but the big idea is simple: APR includes costs tied to getting the credit, not costs you would pay anyway in a cash deal, like title work and taxes.
Why APR is almost always higher
Because APR adds fees on top of the interest rate, it nearly always comes out higher. The bigger the fees, the bigger the gap.
- Small gap: Low fees and no points. APR sits just a little above the rate.
- Big gap: Lots of points, high fees or mortgage insurance. APR climbs well above the rate.
A large gap is a clue to look closer at the fees. Your Loan Estimate shows the APR on page 3, in the “Comparisons” section.
How to compare offers using APR
Offer A: 7.125% rate, 1 discount point ($3,000) plus $1,500 in lender fees. Payment about $2,021. APR about 7.28%.
Offer B: 7.375% rate, no points, $1,500 in lender fees. Payment about $2,072. APR about 7.43%.
Offer C: 7.25% rate, no points, but $6,000 in lender fees. Payment about $2,047. APR about 7.45%.
Offer C has a lower rate than B, but its higher fees give it the highest APR. Offer A wins on APR, but you pay $3,000 more upfront than B.
| Offer | Rate | Upfront lender costs | Monthly P&I | APR |
|---|---|---|---|---|
| A | 7.125% | $4,500 | $2,021 | 7.28% |
| B | 7.375% | $1,500 | $2,072 | 7.43% |
| C | 7.25% | $6,000 | $2,047 | 7.45% |
The time factor: points and break-even
APR assumes you keep the loan for its full term. Most people don’t. They sell or refinance first. That is why you should also figure your break-even point on any points.
In our example, Offer A costs $3,000 more upfront than Offer B and saves about $51 a month. Divide $3,000 by $51 and you get about 59 months, or roughly five years. Keep the loan longer than that and A comes out ahead. Sell or refinance sooner and B is cheaper. Our mortgage points guide walks through this trade in more detail.

Smart rules for comparing offers
- Compare the same kind of loan. A 15-year fixed APR vs a 30-year fixed APR tells you little. See 15 vs 30-year mortgage for that comparison.
- Get quotes on the same day. Rates move daily, so same-day quotes are fairer.
- Match the points. Ask each lender to quote with zero points and with one point so you are comparing like with like.
- Be careful with ARMs. The APR on an adjustable-rate mortgage is based on assumptions about future rates, so it is less reliable.
- Read the fees too. APR is a summary. Section A of the Loan Estimate shows the actual lender charges.
FAQ
Is APR or interest rate more important?
Both matter. The interest rate sets your monthly payment. APR shows the overall cost including fees. Look at both, plus how long you will keep the loan.
Can APR ever be lower than the interest rate?
It is rare. It can happen if a lender gives you a credit that covers more than the finance charges, but for most mortgages APR is equal to or higher than the rate.
Does APR include closing costs?
Some of them. Lender fees, points and mortgage insurance are included. Third-party costs like title insurance, appraisal and taxes generally are not.
Why did my APR change on my Closing Disclosure?
Fees or the rate may have changed. If the APR rises by more than 1/8 of a percentage point on a fixed-rate loan, the lender must give you a new three-business-day review period before closing.
Does locking my rate lock my APR?
A rate lock locks the interest rate and usually the points. APR can still move a bit if other fees in the calculation change.
