Understanding the Difference Between Mortgage Interest Rate and APR

When shopping for a mortgage, you’ll often see two key figures: the Interest Rate and the APR (Annual Percentage Rate). While they may look similar, they represent different costs associated with your home loan. Understanding both is essential for comparing loan offers and making smart financial decisions.

1. What Is a Mortgage Interest Rate?

Definition:The interest rate is the cost you pay annually to borrow money, expressed as a percentage of your loan amount. It directly affects your monthly mortgage payment.

Key facts:

·      Does not include fees or closing costs.

·      Reflects the lender’s base charge for lending you money.

·      Lower interest rates = lower monthly payments.

Example:On a $300,000 loan with a 6% interest rate, your interest-only payment would be $18,000 per year, or $1,500 per month (before taxes and insurance).

2. What Is APR (Annual Percentage Rate)?

Definition:APR is the total cost of borrowing over a year, including the interest rate plus most lender fees, such as:

·      Loan origination fees

·      Discount points

·      Mortgage insurance (in some cases)

·      Some closing costs

Why it matters:APR gives you a more complete picture of what you’ll actually pay over the life of the loan.

Example:A loan with a 6.00% interest rate may have an APR of 6.25% once fees are included.

Key Differences at a Glance

Feature	Mortgage Interest Rate	APR (Annual Percentage Rate)
Includes Fees?	❌ No	✅ Yes
Affects Monthly Payment	✅ Yes	❌ Not directly
Best For	Estimating monthly payments	Comparing total loan costs
Typically Higher?	❌ No	✅ Yes (includes fees)

Why Both Numbers Matter

·      Use the interest rate to understand your monthly payment.

·      Use the APR to compare overall loan costs between lenders.

·      The smaller the gap between the rate and APR, the lower the lender’s fees.

Example Scenario: Comparing Two Lenders

Lender	Interest Rate	APR	Notes
A	6.00%	6.30%	Higher fees included
B	6.00%	6.15%	Lower fees and closing costs

Even though both lenders offer the same interest rate, Lender B is more cost-effective overall due to the lower APR.

Final Tips for Consumers

·      Always request a Loan Estimate (LE) to see the full breakdown of interest rate, APR, and fees.

·      Don’t focus only on the interest rate—look at the APR to see the real cost.

·      Ask your lender to explain all fees included in the APR.

·      Compare APR across multiple lenders before deciding on a mortgage.
