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's often referred to as "interest on interest" and makes a sum grow at a faster rate than simple interest.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + \frac{R}{100})^T \]

Where:

\( A \) — Final amount (principal + interest)
\( P \) — Principal amount (initial investment)
\( R \) — Annual interest rate (in percentage)
\( T \) — Time period (in years)

Explanation: The formula calculates how much an investment will grow over time when interest is compounded annually.

3. Importance of Compound Interest

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

4. Using the Calculator

Tips: Enter the principal amount in currency units, annual interest rate as a percentage, and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does compound interest differ from simple interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any accumulated interest.

Q2: What is the effect of compounding frequency?
A: More frequent compounding (monthly, quarterly) results in higher returns than annual compounding at the same nominal rate.

Q3: Can this calculator handle different compounding periods?
A: This calculator specifically calculates interest compounded yearly. For other compounding frequencies, a different formula would be needed.

Q4: What is the Rule of 72?
A: The Rule of 72 is a simple way to estimate how long an investment will take to double: divide 72 by the annual interest rate.

Q5: How does inflation affect compound interest calculations?
A: Inflation reduces the real value of future money. For accurate long-term planning, consider the real rate of return (nominal rate minus inflation rate).
