1. What is Quarterly Compounding Interest?

Quarterly compounding interest is a method where interest is calculated and added to the principal amount four times a year. This is commonly used in Indian savings accounts, allowing your investment to grow faster as interest earns more interest.

2. How Does the Calculator Work?

The calculator uses the quarterly compounding formula:

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 how much your investment will grow when interest is compounded quarterly, which is the standard practice for most Indian savings accounts.

3. Importance of Interest Calculation

Details: Accurate interest calculation helps investors understand their potential returns, plan their finances better, and compare different investment options to make informed financial decisions.

4. Using the Calculator

Tips: Enter principal amount in INR, annual interest rate as a percentage (e.g., 4.5 for 4.5%), and time period in years. All values must be positive numbers.
