1. What is the Indian Savings Account Interest Formula?

The Indian Savings Account Interest Formula calculates the maturity amount for savings accounts in India, where interest is typically compounded quarterly. This formula helps investors understand how their savings will grow over time with compound interest.

2. How Does the Calculator Work?

The calculator uses the Indian savings account interest formula:

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

Where:

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