Understanding APR vs interest rate can help you better evaluate the cost of borrowing when comparing credit offers. Although the two figures are related, they do not always represent the same costs. Understanding what each one includes can help you compare credit offers more carefully and see how interest and certain fees may affect the overall cost of borrowing.
Quick Answer
Here’s the difference in one breath:
• Interest rate is the percentage charged for borrowing money. It generally does not reflect certain fees or other charges associated with the credit.
• APR (Annual Percentage Rate) is a broader measure of borrowing cost. For many loans, APR reflects the interest rate plus certain fees and charges, expressed as a yearly rate.
Because APR can include costs beyond the interest rate, it can be useful when comparing similar loan offers. However, APR and the costs included in it can work differently depending on the type of credit.
A Closer Look at Each
Interest rate
The interest rate is the percentage a lender charges for borrowing money. It is generally applied to the outstanding balance according to the terms of the loan or credit agreement. The interest rate itself generally does not include certain fees or other charges associated with the credit.
APR
APR is a broader measure of borrowing cost. For many loans, it reflects the interest rate plus certain fees and charges associated with the credit, expressed as a yearly rate. Because APR can include costs beyond the interest rate, it can provide additional information when comparing similar loan offers.
APR vs Interest Rate at a Glance
| Interest Rate | APR | |
|---|---|---|
| What it measures | Cost of borrowing the money | Broader measure of borrowing cost |
| Includes fees? | Generally no | Includes certain fees and charges |
| Which is bigger? | Often lower than the APR | Often higher than the interest rate |
| Best for | Understanding base cost | Comparing similar loan offers |
A Real Example
Imagine two lenders offer similar $10,000 loans with the same 6% interest rate. At first glance, the offers may look similar. However, differences in fees and other loan terms can result in different APRs.
- Lender A: 6% interest rate, with no additional fees included in this simplified example
- Lender B: 6% interest rate, plus a $500 fee that is included in the APR calculation
Even though the two loans have the same interest rate, their APRs may differ because APR can reflect certain fees and charges in addition to interest. Looking at both the interest rate and APR can give you a more complete picture of borrowing costs when comparing similar loan offers.
Why APR Matters Even More for Mortgages
APR can be especially useful when comparing mortgage offers because certain loan costs, such as points and some fees, may be reflected in the APR. Consider two mortgage offers with similar terms:
| Loan | Interest Rate | APR |
|---|---|---|
| Mortgage A | 6.5% | Reflects the rate plus applicable APR costs |
| Mortgage B | 6.25% | Reflects the rate plus applicable APR costs |
Mortgage B has the lower interest rate in this simplified comparison, but the interest rate alone does not show all of the borrowing costs that may be reflected in the APR. When comparing similar mortgage offers, reviewing both the interest rate and APR can help you see how certain fees and other applicable costs affect the overall cost of borrowing.
Important: APR is most useful when comparing mortgage offers with similar loan terms and features. A 15-year mortgage and a 30-year mortgage, for example, have different repayment periods and payment structures, so APR should not be the only factor used to compare them.
Why This Matters for You
Understanding the difference helps you in three big ways:
- You can compare borrowing costs more carefully. Two similar loans with the same interest rate can have different APRs when certain fees and charges differ. Reviewing both figures can give you more information about the cost of each offer.
- You can identify additional borrowing costs. A difference between the interest rate and APR may indicate that certain fees or other finance charges are included in the APR. Reviewing the loan disclosures can help you understand what those costs are.
- You can make a more informed comparison. When loan terms and features are similar, APR can help you compare borrowing costs. Consider the APR along with the interest rate, fees, monthly payment, loan term, and total amount you expect to pay.

What About Credit Cards?
Credit cards work a little differently from many installment loans. A credit card’s APR expresses the cost of borrowing as a yearly rate. Credit cards can have different APRs for different types of transactions, and some cards may also charge fees that are separate from the APR.
Credit cards may have several APRs, including an APR for purchases and different APRs for transactions such as cash advances or balance transfers. The applicable APR can vary by transaction type and by the terms of the card. If you carry a balance, interest charges can increase the cost of the debt over time.

Fixed vs. Variable Rates (A Quick Bonus)
You’ll also hear rates described as fixed or variable:
- Fixed rate: generally remains unchanged for the period specified in the loan or credit agreement, making the interest rate more predictable.
- Variable rate: can increase or decrease over time based on the index or benchmark and other terms specified in the loan or credit agreement. Because the rate can change, future interest costs or payments may also change.
Knowing whether an interest rate is fixed or variable can help you understand how the rate may behave over time and whether changes in the rate could affect your borrowing costs or payments.
Common Mistakes People Make
- Comparing only interest rates. Two similar loans with the same interest rate can have different APRs when certain fees or other borrowing costs differ. Reviewing both the interest rate and APR can give you a more complete comparison.
- Ignoring fees and other costs. A loan with a relatively low interest rate may still include fees or other charges. APR can reflect certain costs beyond the interest rate, so reviewing the APR and loan disclosures can provide a more complete picture of the borrowing costs.
- Assuming an introductory rate will continue indefinitely. Promotional or introductory rates may apply only for a limited period. Review the credit terms to understand how long the introductory rate lasts and what rate may apply afterward.
- Not reviewing the details. If you do not understand why an APR differs from the interest rate, review the loan disclosures and ask the lender to explain which costs are reflected in the APR.
Frequently Asked Questions
Is APR the same as interest rate?
Not necessarily. The interest rate generally represents the percentage charged for borrowing money, while APR is a broader measure that may include the interest rate plus certain fees and other finance charges, depending on the type of credit.
Why is my APR higher than my interest rate?
An APR may be higher than the interest rate because it can reflect certain fees and other finance charges in addition to interest. Which costs are included in the APR depends on the type of credit and the applicable terms.
Which number should I use to compare loans?
APR can be useful when comparing similar loan offers because it may reflect certain borrowing costs beyond the interest rate. Review the APR along with the interest rate, fees, loan term, monthly payment, and other important terms before comparing offers.
Are APR and interest rate the same on credit cards?
Credit card APR expresses the cost of borrowing as a yearly rate. A credit card may have different APRs for purchases, cash advances, balance transfers, or other transactions, depending on the card’s terms. Some fees may also be charged separately from the APR.
Is a lower APR always better?
A lower APR can indicate lower borrowing costs when you are comparing similar loan offers, but APR should not be considered by itself. Compare the loan term, monthly payment, fees, prepayment terms, and other features that may affect the overall cost of borrowing.
The Bottom Line
The interest rate and APR provide different information about borrowing costs. The interest rate generally shows the percentage charged for borrowing money, while APR can provide a broader measure by reflecting certain fees and finance charges in addition to interest. When comparing similar loan offers, reviewing both numbers can help you better understand how the costs differ.
