When comparing mortgage offers, most buyers immediately look at one number:
The interest rate.
While the interest rate is extremely important, it doesn’t always tell you the complete cost of a mortgage.
That’s where APR comes in.
APR, which stands for Annual Percentage Rate, is designed to give borrowers a broader picture of the cost of borrowing money.
Two mortgage loans can have the same interest rate but different APRs. This can happen because the loans have different fees and costs associated with them.
For first-time home buyers, understanding the difference between APR and interest rate can make comparing mortgage offers much easier.
However, APR is also commonly misunderstood.
A lower APR doesn’t automatically mean one mortgage is always better than another, and the interest rate shouldn’t be ignored either.
The key is understanding what each number tells you.
What Does APR Mean on a Mortgage?
APR stands for Annual Percentage Rate.
On a mortgage, the APR is intended to reflect the broader annual cost of borrowing by taking into account the interest rate and certain fees associated with the loan.
The interest rate tells you the cost of borrowing the principal.
APR provides a broader estimate by incorporating additional costs into the calculation.
These costs may include certain lender fees and other finance charges associated with obtaining the mortgage.
This is why the APR is often higher than the advertised interest rate.
For example:
- Mortgage interest rate: 6.00%
- Mortgage APR: 6.35%
The difference between the two numbers represents additional costs associated with the loan.
APR can therefore be useful when comparing mortgages with similar terms.
APR vs Interest Rate: What’s the Difference?
The easiest way to understand the difference is this:
Interest rate = the cost of borrowing the money
APR = a broader estimate of the cost of the loan
Let’s look at a simplified example.
Imagine two lenders offer you the same mortgage.
Lender A
- Interest rate: 6.00%
- Lower fees
- APR: 6.20%
Lender B
- Interest rate: 6.00%
- Higher fees
- APR: 6.45%
Both loans have the same interest rate.
However, Lender B has a higher APR because the overall financing costs are higher.
If you only compared the interest rate, both mortgages might appear identical.
Looking at the APR gives you additional information about the total borrowing costs.
Why Is APR Higher Than the Interest Rate?
APR is often higher than the mortgage interest rate because it can include certain costs associated with obtaining the loan.
Depending on the mortgage, these costs may include:
- Origination fees
- Discount points
- Certain lender charges
- Other applicable finance charges
The exact costs included in APR calculations can vary.
Not every expense connected to buying a home is necessarily included.
For example, some costs related to property ownership, taxes, insurance, or third-party services may not be reflected in the APR.
This is why APR should be viewed as a comparison tool rather than a complete representation of every dollar you’ll spend buying a home.
How Does APR Work on a Mortgage?
APR takes certain upfront costs and spreads them across the expected life of the loan to create an annualized percentage.
This helps borrowers compare the cost of different loans.
For example, imagine two 30-year mortgages.
Both have similar loan amounts.
However:
Mortgage A
- Interest rate: 6%
- Low upfront fees
- APR: 6.15%
Mortgage B
- Interest rate: 5.85%
- Higher upfront fees
- APR: 6.30%
Mortgage B has a lower interest rate.
But because it includes higher upfront costs, its APR is higher.
This demonstrates why choosing a mortgage based solely on the lowest advertised interest rate can sometimes be misleading.
A lower rate may come with higher fees.
APR helps reveal some of those differences.
Is a Lower APR Always Better?
Not necessarily.
APR is extremely useful, but it shouldn’t be the only factor you consider.
One of the limitations of APR is that it assumes you’ll keep the mortgage for a certain period, often based on the loan’s full term.
In reality, many homeowners:
- Sell their homes
- Refinance their mortgages
- Pay off their loans early
If you don’t keep the mortgage for a long time, paying significant upfront fees to receive a slightly lower interest rate may not make financial sense.
For example, imagine:
Option A
- Interest rate: 6.25%
- Very low closing costs
Option B
- Interest rate: 6.00%
- High upfront fees
Option B may have a competitive APR over a long period.
But if you sell the home after three years, you may not have enough time to recover the additional upfront costs.
This is why it’s important to consider your expected time in the home.
APR and Mortgage Points
Mortgage points are one of the reasons APR can differ from the interest rate.
A borrower may choose to pay discount points upfront to reduce their mortgage interest rate.
Each point generally costs a percentage of the loan amount, although the exact impact on your interest rate depends on the lender and loan terms.
For example, you might pay an upfront amount to reduce your interest rate from:
6.5% → 6.25%
This could lower your monthly payment.
However, it also increases your upfront borrowing costs.
The APR calculation can help reflect this trade-off.
Whether mortgage points make financial sense depends largely on how long you expect to keep the loan and how much you save each month.
The important question isn’t simply:
“Can I get a lower interest rate?”
It’s:
“Will the savings eventually exceed the upfront cost?”
APR vs APY: Don’t Confuse Them
APR and APY are often confused, but they are used differently.
APR
APR is commonly used when discussing the cost of borrowing money.
You’ll see it on:
- Mortgages
- Credit cards
- Personal loans
- Auto loans
APY
APY stands for Annual Percentage Yield.
It is commonly used to describe the return you earn on money in an interest-bearing account.
For example:
- Savings accounts
- Certificates of deposit
- Certain investment products
APR generally relates to what you pay to borrow.
APY generally relates to what you earn on deposits or investments.
How to Use APR When Comparing Mortgage Offers
APR can be particularly useful when comparing similar mortgage products.
For example, suppose you’re comparing two 30-year fixed-rate mortgages for the same loan amount.
If one lender offers:
- 6.10% interest rate
- 6.25% APR
And another offers:
- 6.10% interest rate
- 6.55% APR
The higher APR may indicate higher costs associated with the loan.
However, don’t stop there.
You should also compare:
- Closing costs
- Lender fees
- Mortgage points
- Monthly payment
- Loan term
- Prepayment terms
- Estimated cash required at closing
APR gives you a useful starting point, but the full loan estimate provides more detail.
Why APR Can Be Misleading When Comparing Different Loans
APR comparisons are most useful when the loans are similar.
Comparing the APR of completely different mortgage structures can sometimes be less straightforward.
For example:
- A 15-year fixed mortgage
- A 30-year fixed mortgage
- A 5/1 ARM
These loans have different structures and repayment timelines.
A lower APR on one doesn’t automatically mean it’s the better financial choice.
The monthly payment, risk level, loan duration, and future rate adjustments should also be considered.
This is especially important when comparing fixed-rate and adjustable-rate mortgages, since an ARM may have a lower introductory rate but a different long-term risk profile.
What Costs Are Not Included in APR?
One of the biggest misconceptions about APR is believing it represents every cost associated with buying a home.
It doesn’t.
Depending on the situation, costs that may not be fully reflected in APR include:
- Property taxes
- Homeowners insurance
- Home maintenance
- HOA fees
- Moving expenses
- Certain third-party costs
These expenses can significantly affect the total cost of homeownership.
That’s why you shouldn’t use APR as your only measure of affordability.
A mortgage with a competitive APR can still be financially difficult if the property’s taxes, insurance, or maintenance costs are high.
How Much Does APR Matter?
APR matters most when you’re actively comparing mortgage offers.
It helps you move beyond the headline interest rate.
Imagine seeing two advertisements:
Mortgage A: 5.99%
Mortgage B: 6.05%
At first glance, Mortgage A looks cheaper.
But what if:
Mortgage A has a much higher APR because of significant lender fees?
Mortgage B might actually be more cost-effective depending on your situation.
APR encourages you to look beyond the advertised rate.
This is particularly important because mortgage advertisements often emphasize the lowest possible interest rate.
The actual rate you qualify for may depend on your financial profile.
Interest Rate vs APR: Which One Should You Focus On?
The answer is:
Both.
The interest rate directly affects your monthly principal and interest payment.
APR provides additional information about certain borrowing costs associated with the loan.
When comparing mortgage offers, look at:
Interest Rate
How much will borrowing the money cost you over time?
APR
What is the broader annualized cost when certain fees are included?
Closing Costs
How much cash do you need upfront?
Monthly Payment
Can you comfortably afford the payment?
Loan Term
How long will you repay the mortgage?
Your Expected Timeline
How long do you realistically expect to keep the loan?
Looking at all these factors together provides a much clearer picture.
A Simple Example: Comparing Two Mortgage Offers
Imagine you’re comparing two lenders for a $350,000 mortgage.
| Lender A | Lender B | |
|---|---|---|
| Interest Rate | 6.00% | 5.90% |
| APR | 6.20% | 6.35% |
| Upfront Fees | Lower | Higher |
| Monthly Payment | Slightly Higher | Slightly Lower |
Which mortgage is better?
There isn’t enough information to answer immediately.
Lender B has a lower interest rate and lower monthly payment.
But it also has a higher APR and higher upfront costs.
If you plan to keep the mortgage for a long time, the lower rate may eventually offset the higher fees.
If you plan to refinance or sell relatively soon, paying high upfront fees may not be worthwhile.
This is why mortgage comparisons should be based on your personal timeline rather than one single number.
Common Mistakes When Comparing APR
Choosing the Lowest APR Without Looking at the Details
APR is useful, but you should still review the individual fees and costs.
Looking Only at the Interest Rate
A low interest rate can sometimes come with higher upfront costs.
Ignoring How Long You’ll Keep the Mortgage
Upfront costs matter more if you don’t keep the loan long enough to recover them.
Comparing Completely Different Loan Types
APR is most useful when comparing similar mortgages.
Ignoring Monthly Affordability
The best long-term loan isn’t helpful if the monthly payment doesn’t fit your budget.
Final Thoughts
APR is an important tool for comparing mortgage offers, but it shouldn’t be used in isolation.
Your mortgage interest rate tells you the direct cost of borrowing money.
APR provides a broader view by incorporating certain fees and costs associated with the loan.
A lower APR can be a positive sign when comparing similar mortgages, but it doesn’t automatically mean one loan is better for every borrower.
The best approach is to look at the complete picture:
- Interest rate
- APR
- Closing costs
- Monthly payment
- Loan term
- Upfront fees
- Your expected time in the home
A mortgage is a long-term financial commitment.
Taking a few extra minutes to understand the numbers can potentially save you thousands of dollars over the life of the loan.
Frequently Asked Questions
What is a good APR for a mortgage?
There is no single “good” APR because mortgage pricing changes over time and depends on factors such as your credit profile, loan type, down payment, and market conditions. It’s generally more useful to compare APRs between similar loan offers available to you.
Why is APR higher than my mortgage interest rate?
APR can include certain fees and finance charges associated with obtaining the mortgage, while the interest rate primarily reflects the cost of borrowing the principal amount.
Is APR more important than the interest rate?
Neither number should be viewed alone. The interest rate directly affects your monthly principal and interest payment, while APR provides a broader estimate of certain borrowing costs.
Does APR include property taxes and homeowners insurance?
Generally, APR is not intended to represent every cost of homeownership. Property taxes, homeowners insurance, maintenance, and other ownership expenses should be evaluated separately.
Can two mortgages have the same interest rate but different APRs?
Yes. Two loans can have the same interest rate but different APRs if the associated fees and finance charges differ.
