1. What is the Savings Account Interest Formula?

The savings account interest formula calculates the maturity amount for Indian savings accounts, which typically use quarterly compounding. This provides a more accurate estimate of your savings growth over time compared to simple interest calculations.

2. How Does the Calculator Work?

The calculator uses the quarterly compounding formula:

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)

Explanation: The formula calculates compound interest with quarterly compounding, which is common for Indian savings accounts. Interest is added to the principal every three months, allowing your money to grow faster over time.

3. Importance of Interest Calculation

Details: Accurate interest calculation helps in financial planning, understanding how your savings grow over time, and comparing different savings options to maximize returns on your investments.

4. Using the Calculator

Tips: Enter principal amount in INR, annual interest rate in decimal form (e.g., 0.05 for 5%), and time period in years. All values must be positive numbers.
