1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It's a powerful concept in finance where your money grows at an accelerating rate over time, making it particularly beneficial for long-term investments.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + r/n)^{n \times t} \]

Where:

\( A \) — Future value of the investment/loan
\( P \) — Principal investment amount (initial deposit)
\( r \) — Annual interest rate (in decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Number of years the money is invested/borrowed

Explanation: The formula calculates how much your investment will grow over time with compound interest, taking into account how frequently the interest is compounded.

3. Importance of Compound Interest in India

Details: Compound interest is fundamental to various Indian investment vehicles including fixed deposits, recurring deposits, mutual funds, PPF, and other long-term savings instruments. Understanding compound interest helps Indian investors make informed decisions about their financial future.

4. Using the Calculator

Tips: Enter principal amount in Indian rupees, annual interest rate as a percentage, number of compounding periods per year (e.g., 12 for monthly, 4 for quarterly, 1 for annually), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest, leading to faster growth.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (monthly vs annually) results in higher returns due to interest being calculated and added to the principal more often.

Q3: What are common compounding frequencies in India?
A: Common frequencies include annually, semi-annually, quarterly, and monthly, depending on the financial product.

Q4: Is compound interest taxable in India?
A: Yes, interest earned through compound interest is generally taxable under the Income Tax Act, 1961, unless specifically exempted.

Q5: Which Indian investments use compound interest?
