APR vs interest rate: what's the difference on a loan?
Edited by Moe Ameen · Published
The interest rate is what you pay each year to borrow the money, and it leaves fees out. The APR is the yearly cost of the credit under the Truth in Lending Act's Regulation Z, so it adds finance charges like points and loan fees. That's why two loans at the same rate can carry different APRs. At 12% over three years, a $10,000 loan has a 12.00% APR with no fee and 15.61% with a 5% fee.
Key takeaways
- The rate prices the money. The APR prices the money plus the fees the lender charges to make the loan.
- Regulation Z counts points, loan fees and lender-required insurance in the APR. Late fees don't count.
- On a mortgage, the rate is on page 1 of the Loan Estimate and the APR is on page 3.
- Same rate, bigger fee, higher APR. Compare APRs on loans of the same type and length.
What is the difference between APR and interest rate?
The interest rate is the yearly cost of borrowing the money alone. The APR adds the lender's fees and other finance charges, so it's usually higher.
The CFPB puts it plainly: the interest rate "does not reflect fees or any other charges you may have to pay for the loan," while the APR reflects the rate plus points, broker fees and other charges you pay to get the loan [1]. Regulation Z defines the APR as "a measure of the cost of credit, expressed as a yearly rate" [3]. Bankrate describes the two the same way [4].
| Interest rate | APR | |
|---|---|---|
| What it measures | Yearly cost of the money borrowed | Yearly cost of the credit, fees included |
| Includes interest | Yes | Yes |
| Includes points and loan fees | No | Yes |
| Includes lender-required insurance | No | Yes, when the lender requires it |
| Includes late fees | No | No |
| Sets your monthly payment | Yes | No |

What does APR include under Regulation Z?
Every finance charge: interest, points, loan and finder's fees, service charges, appraisal and credit report fees, and insurance the lender requires.
Regulation Z calls the finance charge "the cost of consumer credit as a dollar amount," meaning charges you pay that the lender imposes as a condition of the credit [2]. The APR turns that dollar figure into a yearly rate. Its list of examples includes [2]:
- Interest, and any add-on or discount charges.
- Service, transaction and carrying charges.
- Points, loan fees, assumption fees and finder's fees.
- Appraisal, investigation and credit report fees.
- Premiums for insurance that protects the lender if you default.
- Premiums for credit life, accident, health or loss-of-income insurance written with the loan.
- Charges for debt cancellation or debt suspension coverage.
Insurance is where this bites on car loans. The CFPB says that if a lender truly requires GAP insurance to get the financing, its cost must be in the finance charge and the disclosed APR. If it's optional, you can say no [7].
What does APR leave out?
Late and over-limit fees, application fees charged to every applicant, seller's points, and on mortgages, title, appraisal, notary and credit report fees.
Regulation Z excludes these from the finance charge [2]:
- Application fees charged to all applicants, whether or not they get the credit.
- Charges for late payment, going over a credit limit, or default.
- Fees for taking part in a credit plan, such as a yearly fee.
- Seller's points.
- On loans secured by real estate, bona fide and reasonable fees for title work, document preparation, notary and credit reports, appraisals and inspections done before closing, and escrow deposits.
So a mortgage APR doesn't hold every closing cost. Bankrate makes the same point about credit report and appraisal fees [4]. The CFPB adds two more limits: an adjustable-rate mortgage's APR doesn't show the highest rate the loan can reach, and a home equity line's APR doesn't include fees at all, so you can't fairly compare it with a closed-end loan's APR [1].
Why is a mortgage APR higher than the note rate?
Because the APR spreads the points and origination charges over the loan. On a $300,000 loan at 6.5%, $4,500 in fees lifts the APR to about 6.65%.
The note rate is the interest rate written into the loan, the one that sets your payment. On a Loan Estimate the CFPB says you'll find it on page 1 under Loan Terms, with the APR on page 3 under Comparisons [1]. The gap between the two is the fees.
| Points and origination charges | Note rate | APR |
|---|---|---|
| $0 | 6.500% | 6.500% |
| $4,500 (1 point plus a $1,500 origination fee) | 6.500% | 6.646% |
| $9,000 | 6.500% | 6.795% |
Bankrate's own example lands in the same place: a 7% rate with a 1% origination fee shows a 7.099% APR, and adding one point raises it to 7.197% [4].
How can two loans with the same rate have different APRs?
The fees differ. Same rate means the same payment, but a fee taken out of the loan means you get less cash, and the APR counts that.
Most personal loan fees come out of the money you receive. Happen Bank's published example is $15,262 at 13.99% over 36 months with a 6% fee of $916: you receive $14,346, pay $522 a month, and the APR is 18.40% [5]. Prosper's is a three-year $10,000 loan at 17.29% with an 8.99% fee, which comes to a 24.19% APR on $9,101 received [6].
Regulation Z also gives lenders a little room. On a regular loan, a disclosed APR counts as accurate if it's within 1/8 of a percentage point of the true figure, or 1/4 of a point on irregular loans [3]. So two quotes 0.1 point apart may really be the same price.
When is the APR not enough to compare loans?
When the loans differ in type or length, when one rate can change, or when you plan to pay early. The CFPB says not to judge on APR alone.
The CFPB warns against comparing fixed-rate and adjustable-rate APRs, or a closed-end loan with a home equity line, and says "Don't look at the APR alone" [1]. Term matters too. The same fee spread over fewer years produces a higher APR, even though the dollars are identical.
Paying a loan off early works against you when there's a big up-front fee. The APR assumes you keep the loan for the full term. Pay it off in a year and you've paid the whole fee for one year of borrowing. If you might do that, compare the total fees in dollars as well as the APR.
Glisten math
One rate, four fees, four APRs
| Origination fee | Cash you receive | Total cost of the loan | APR |
|---|---|---|---|
| None | $10,000 | $1,957.15 | 12.00% |
| 3% ($300) | $9,700 | $2,257.15 | 14.13% |
| 5% ($500) | $9,500 | $2,457.15 | 15.61% |
| 8% ($800) | $9,200 | $2,757.15 | 17.90% |
We checked the method against lenders' own disclosures. Run the same way, Happen Bank's example gives 18.40% and Prosper's gives 24.19%, the APRs each lender prints [5][6]. If the 5% fee is added to the balance instead (you borrow $10,500 and get $10,000), the payment rises to $348.75 and the APR is 15.43%.
Is this right for you?
Best for
- Comparing two quotes for the same kind of loan over the same term.
- Spotting how much of a loan's cost is fees rather than interest.
Not ideal for
- Comparing a fixed-rate loan with an adjustable one, or a loan with a home equity line.
- Working out your monthly payment. That comes from the interest rate.
Frequently asked questions
Is APR always higher than the interest rate?
Usually, says the CFPB, because it adds points and fees [1]. With no finance charges beyond interest, the two match: our no-fee example is 12% and 12.00% APR.
Does APR include late fees?
No. Regulation Z leaves charges for late payment, going over a limit and default out of the finance charge [2].
Is an application fee part of the APR?
Not if the lender charges it to every applicant, whether or not they get the loan. Regulation Z excludes that kind of fee [2].
How accurate does a lender's APR have to be?
Within 1/8 of a percentage point on a regular loan, and 1/4 of a point on irregular ones, such as loans with multiple advances [3].
Where do I find the APR on a mortgage offer?
On page 3 of the Loan Estimate, under Comparisons. The interest rate is on page 1 under Loan Terms [1].
How we know this
On November 2, 2026 we read Regulation Z's finance charge and APR sections on the CFPB's site, the CFPB's explainer on rates and APRs, and the personal loan pages of Happen Bank and Prosper. We checked the general definitions against Bankrate. Every APR in our tables is our own arithmetic, and it reproduces both lenders' published examples.
