What is the difference between a loan interest rate and the APR?

When you apply for a loan, you see two main terms: interest rate and APR. They sound similar but they’re not the same—and the difference can cost you thousands. APR, or annual percentage rate, gives you a more accurate picture of what a loan really costs by including not just the interest but also the fees.
In this guide, Keyswag Lending breaks down how APR works, how it compares to an interest rate, and how understanding both can help you make better borrowing decisions.
What is an Interest Rate?
An interest rate is the basic percentage a lender charges on the principal amount of a loan. It’s the rate you see advertised. For example, if you borrow $10,000 at 5% interest, you’ll pay $500 per year in interest, not counting fees.
But this rate doesn’t include extra costs like origination fees or closing costs. That’s where APR comes in to show the whole picture.
What is APR (Annual Percentage Rate)?
APR stands for Annual Percentage Rate and is the total yearly cost of a loan, including the interest rate and fees. These might include underwriting fees, loan processing fees, discount points and more. APR helps you compare different lenders and loan types more fairly.
It’s a requirement for lenders to disclose the APR by law so you can be transparent. Whether you’re applying for Conventional Loans or Bank Statement Loans, knowing the APR tells you what you’ll actually pay per year.
Key Differences Between APR and Interest Rate
While the interest rate is the base cost of borrowing, APR includes the other charges tied to the loan. This is important when comparing loan offers, especially mortgages or Hard Money Loans.
For example, one loan might have a 6% interest rate with minimal fees and another 5.5% rate with big closing costs—making the APR higher. Always look beyond the interest rate to get the real cost comparison.
Fixed vs. Variable APRs
A fixed APR stays the same throughout the loan term, with predictable payments. A variable APR can change with market trends, often tied to indexes like the prime rate. Variable APRs may start lower but can increase, affecting your monthly payments.
Fixed APRs are better for stability, while variable APRs might be for short-term loans or borrowers planning to refinance. At Keyswag Lending, we help you evaluate both options under our Loan Options.
How APR Impacts Your Loan Cost
APR directly affects your total loan cost. Let’s say you’re comparing two 30-year mortgages in Phoenix. One has a 6.0% interest rate and a 6.2% APR, while another has a 5.75% interest rate and a 6.5% APR.
Over the life of the loan, that difference could be tens of thousands of dollars. Use our Loan Rate Calculator to see the long-term effects of APR and fees on your loan.
Mortgage APR vs. Personal Loan APR vs. Credit Card APR
APR varies by loan type. Mortgage APR includes points, closing costs and origination fees. Personal loan APRs are simpler but can include admin fees. Credit card APR applies to unpaid balances and can be variable or fixed.
If you’re applying for a mortgage in Las Vegas, you’ll want to consider both the interest rate and APR when choosing between lenders. Our Mortgage Calculator can help.
How to Lower Your APR
Improving your credit score is one of the best ways to get a lower APR. Other tips include reducing your debt-to-income ratio, choosing shorter loan terms and avoiding add-ons.
Shopping around for lenders in cities like Denver or working with brokers like Keyswag can make a big difference. We help you understand all your options through our Service Areas.
When APR Matters Most
APR matters most for long-term loans, like 30-year mortgages, where small percentage differences mean thousands in extra payments. It’s also important when comparing multiple loan offers with different fee structures.
For short-term or zero-fee loans, APR may not matter as much. But if you’re financing a home or considering a refinance, comparing APRs is key to making a cost-effective decision.
