1. What is the Savings Interest Rate Calculator?

The Savings Interest Rate Calculator helps determine the annual interest rate earned on savings based on the compound interest formula. It calculates the rate that would grow a principal amount to a specific amount over a given time period with a certain 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 (currency units)
\( P \) — Principal amount (currency units)
\( n \) — Compounding frequency (unitless)
\( T \) — Time period (years)

Explanation: The formula calculates the annual interest rate required for a principal amount to grow to a specific amount over a given time with a certain compounding frequency.

3. Importance of Interest Rate Calculation

Details: Understanding the effective interest rate helps savers compare different investment options, plan financial goals, and maximize returns on savings.
