1. What is the PNB Saving Account Interest Formula?

The PNB (Punjab National Bank) saving account interest formula calculates the maturity amount using quarterly compounding interest. This formula is specifically designed for SBI (State Bank of India) style savings accounts, assuming a typo reference to PNB.

2. How Does the Calculator Work?

The calculator uses the compound interest formula with quarterly compounding:

\[ A = P \times (1 + R / 4)^{4 \times T} \]

Where:

\( P \) — Principal amount (initial investment in INR)
\( R \) — Annual interest rate (in decimal form)
\( T \) — Time period in years
\( A \) — Maturity amount (final amount in INR)

Explanation: The formula calculates compound interest with quarterly compounding (4 times per year), which is common for bank savings accounts in India.

3. Importance of Interest Calculation

Details: Accurate interest calculation helps savers understand their potential earnings, compare different investment options, and plan their financial future effectively.
