1. What is the Interest Rate Formula?

The interest rate formula calculates the annual percentage rate for used car loans in Indiana based on the compound interest formula. It determines the rate that would grow a principal amount to a specified amount over a given time period with a specific compounding frequency.

2. How Does the Calculator Work?

The calculator uses the interest rate formula:

\[ R = n \times \left( \left( \frac{A}{P} \right)^{\frac{1}{n \times T}} - 1 \right) \times 100 \]

Where:

$ R $ — Annual interest rate (%)
$ A $ — Final amount ($)
$ P $ — Principal amount ($)
$ n $ — Compounding frequency (times per year)
$ T $ — Time period (years)
