What is the APR Calculator?
The APR Calculator calculates the true Annual Percentage Rate (APR) on any loan. By factoring in origination points, processing fees, underwriting charges, and closing costs, it uncovers the true annual cost of borrowing beyond the nominal advertised interest rate.
How to Use This Calculator
- 1Input the total loan amount requested and nominal base interest rate.
- 2Select the full loan term in years or months.
- 3Enter all upfront lender fees, points, and finance charges.
- 4Compare the nominal interest rate with the true effective APR to evaluate competing lender offers.
The Math Behind It
APR represents the internal rate of return (IRR) that equates the net loan proceeds (Loan Amount minus Prepaid Finance Charges) to the present value of all scheduled future monthly installments.
Frequently Asked Questions
Q:Why is the APR higher than the advertised interest rate?
The nominal interest rate only reflects the percentage charged on the principal balance. The APR reflects the total cost of credit, bundling upfront lender fees, points, and finance charges into an annualized percentage.
Q:Does APR matter if I plan to pay off or refinance my loan early?
Yes. When you pay off a loan early, upfront fees are amortized over a shorter timeframe, making the effective true borrowing cost even higher than the 30-year stated APR.
Q:Are all closing costs included in mortgage APR calculations?
No. Only lender finance charges (points, origination fees, processing fees) are included in APR. Third-party fees like title insurance, appraisal, and recording fees are typically excluded.
Q:Can I use APR to compare loans with different terms?
APR is most accurate when comparing loans with identical repayment durations (e.g., comparing two 30-year loans side-by-side).
