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 exponentially over time, making it a powerful concept in finance.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + R)^T \]

Where:

\( P \) — Principal amount (initial investment)
\( R \) — Annual interest rate (in decimal form)
\( T \) — Time in years
\( A \) — Maturity amount (final amount)

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

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning, investment decisions, and retirement savings. It demonstrates how money can grow over time through the power of compounding.

4. Using the Calculator

Tips: Enter the principal amount in currency, annual interest rate as a decimal (e.g., 0.05 for 5%), 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 the result?
A: More frequent compounding (monthly, quarterly) results in higher returns. This calculator assumes annual compounding.

Q3: Can I use this for different currencies?
A: Yes, the calculator works with any currency as long as you maintain consistent currency units for principal and result.

Q4: What if I have additional contributions?
A: This calculator assumes a single lump sum investment. For regular contributions, a different formula would be needed.

Q5: How accurate is this calculation for real investments?
A: This provides a theoretical calculation. Actual investment returns may vary due to fees, taxes, and fluctuating interest rates.
