APR vs Interest Rate
APR (Annual Percentage Rate) includes fees and closing costs, while the nominal interest rate doesn't. Comparing APRs is the only fair way to compare loans with different fee structures. A 6.5% loan with $5,000 fees has a higher APR than an advertised-low 6.5% with no fees.
What Counts as a Fee
Origination fees, discount points, mortgage insurance, and processing fees — all rolled into the APR calculation. Third-party costs like title insurance and appraisal sometimes do, sometimes don't, depending on lender.
How It's Calculated
APR is the internal rate of return where the present value of all payments equals (loan amount minus fees). We iterate to find the rate that satisfies this equation. Accurate to 0.01%.
FAQ
Is the advertised rate or APR the "real" rate?
APR is the truer picture of cost. Always compare APR across lenders to compare apples to apples.
