1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. It allows your investment to grow at a faster rate compared to simple interest.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + \frac{r}{12})^{(12 \times t)} \]

Where:

\( A \) — Future value of the investment/loan
\( P \) — Principal investment amount (initial deposit)
\( r \) — Annual interest rate (in decimal)
\( t \) — Time the money is invested/borrowed for, in years

Explanation: The formula calculates how much your investment will grow when interest is compounded monthly, taking into account both your initial principal and accumulated interest.

3. Importance of Compound Interest

Details: Compound interest is a powerful concept in finance that allows investments to grow exponentially over time. It's essential for retirement planning, long-term savings, and understanding the true cost of borrowing.

4. Using the Calculator

Tips: Enter the principal amount in ₹, annual interest rate as a percentage, and time 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.

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

Q3: Can I use this calculator for different currencies?
A: Yes, the calculator works with any currency. Just enter the principal amount in your desired currency.

Q4: Is compound interest always beneficial?
A: While beneficial for investments and savings, compound interest can work against you when borrowing money, as debt can grow rapidly.

Q5: How accurate is this calculator for real-world scenarios?
A: This calculator provides theoretical results. Actual returns may vary due to fees, taxes, and fluctuating interest rates.
