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 allows investments to grow at an accelerating rate over time, making it a powerful wealth-building tool.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Future value of the investment
\( P \) — Principal investment amount
\( r \) — Annual interest rate (in decimal form)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested for (in years)

Explanation: The formula calculates how much your investment will grow when interest is earned on both the principal and accumulated interest over time.

3. Importance of Compound Interest

Details: Compound interest is fundamental to long-term investing and wealth accumulation. It demonstrates how small, regular investments can grow significantly over time, highlighting the importance of starting early and allowing investments to compound.

4. Using the Calculator

Tips: Enter the principal amount in ₹, annual interest rate as a percentage, select compounding frequency, 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 exponential growth.

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

Q3: What is a typical interest rate for investments?
A: Interest rates vary widely depending on the investment type. Savings accounts may offer 2-4%, while stocks historically average 7-10% annually over the long term.

Q4: How important is the time factor in compound interest?
A: Time is crucial. The longer your money compounds, the more significant the growth due to the exponential nature of the calculation.

Q5: Can this calculator be used for different currencies?
A: Yes, the calculation works for any currency. Simply enter the principal amount in your preferred currency, and the result will be in the same currency.
