1. What is the India Post Bank Interest Rate Formula?

The India Post Bank Interest Rate formula calculates the annual interest rate (R) based on the amount (A), principal (P), compounding frequency (n), and time (T). This formula helps determine the effective interest rate for investments or loans with compound interest.

2. How Does the Calculator Work?

The calculator uses the India Post Bank 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 (%)
\( A \) — Amount (currency units)
\( P \) — Principal (currency units)
\( n \) — Compounding frequency (unitless)
\( T \) — Time (years)

Explanation: The formula calculates the effective annual interest rate by considering the compounding effect over the given time period.
