Annual Percentage Rate (APR) Simply Explained
When shopping for a loan, comparing only the interest rate can be misleading. A loan with a lower interest rate might carry high closing costs or administration fees that make it more expensive than a loan with a slightly higher interest rate. The **Annual Percentage Rate (APR)** solves this problem.
How is APR Computed?
APR takes the total fees and interest you will pay and expresses them as a single annualized percentage rate.
Calculating APR requires finding the interest rate $i$ that makes the present value of all future monthly payments equal to the net amount of cash you receive. Because this equation cannot be solved directly with simple algebra, the calculator uses an iterative numerical method (specifically the **bisection search**) to approximate the APR to high precision.
The Difference Between Financed and Upfront Fees
If you choose to **finance the fees**, they are added to the principal balance of the loan, increasing your monthly payment. If you choose **not to finance the fees**, you pay them in cash at closing. The monthly payment is smaller, but the net cash you receive from the lender is reduced by the fee amount. In both cases, the calculated APR is higher than the nominal interest rate because the fees represent a borrowing cost.
