1. What is the Indian Bank Savings Account Interest Formula?

The formula calculates the maturity amount for Indian bank savings accounts using quarterly compounding. It accounts for the principal amount, annual interest rate, and time period to determine the final amount including compounded interest.

2. How Does the Calculator Work?

The calculator uses the quarterly compounding formula:

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

Where:

\( A \) — Maturity amount (INR)
\( P \) — Principal amount (INR)
\( R \) — Annual interest rate (decimal)
\( T \) — Time period (years)

Explanation: The formula compounds interest quarterly (4 times per year), which is the standard practice for most Indian bank savings accounts.

3. Importance of Quarterly Compounding

Details: Quarterly compounding allows interest to be calculated and added to the principal every three months, leading to higher returns compared to annual compounding due to the compounding effect.

4. Using the Calculator

Tips: Enter principal amount in INR, annual interest rate as a percentage, and time period in years. All values must be positive numbers.
