Understanding APR vs Interest Rate

APR Calculation
LoanFees = PMT · 1 − (1 + r)n r
Solve for r (monthly APR), then APR = r × 12  •  Fees = origination + points + closing costs + prepaid interest

The interest rate is the cost of borrowing the principal loan amount, expressed as a percentage. The APR (Annual Percentage Rate) is the total cost of the loan including the interest rate plus fees, points, and other charges, expressed as a yearly rate. APR gives a more accurate picture of what you're actually paying.

Why APR Is Always Higher Than the Interest Rate

APR includes costs that the simple interest rate ignores: origination fees, discount points, mortgage broker fees, closing costs, and prepaid interest. Because these costs increase the effective price of borrowing without changing the monthly payment amount, the APR is always equal to or higher than the stated interest rate.

What Fees Are Included in APR?

Under the Truth in Lending Act (TILA), lenders must include origination fees, discount points, mortgage broker fees, and certain closing costs in the APR calculation. Items typically excluded are appraisal fees, title insurance, credit report fees, and home inspection costs, though rules vary.

How to Use APR When Comparing Loans

APR is the best tool for comparing loans from different lenders. A loan with a lower interest rate but higher fees might have a higher APR than a loan with a slightly higher rate and fewer fees. Always compare APRs for the same loan term to make an apples-to-apples comparison.

APR Limitations

APR assumes you keep the loan for its full term. If you refinance or sell before that, the upfront costs are amortized over fewer years, making the effective rate even higher. For short-term ownership, a loan with lower fees but a slightly higher rate may actually cost less.

Frequently Asked Questions

What is APR?
APR stands for Annual Percentage Rate. It represents the true yearly cost of borrowing, including interest and fees, expressed as a single percentage. It helps borrowers compare the actual cost of different loan offers.
Why is my APR different from my interest rate?
APR includes additional costs like origination fees, discount points, and closing costs that the interest rate alone doesn't reflect. The more fees a loan carries, the bigger the gap between the rate and APR.
Is a lower APR always better?
Generally yes, when comparing loans with the same term. However, if you plan to sell or refinance within a few years, a loan with a higher APR but lower upfront fees might save you more money.
Does APR include property taxes and insurance?
No. APR only includes costs associated with the loan itself. Property taxes, homeowner's insurance, and PMI are not factored into the APR calculation.
