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 savings to grow at a faster rate compared to simple interest, making it a powerful concept 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 form)
\( n \) — Number of times interest is compounded per year
\( t \) — Number of years the money is invested/borrowed

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

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is crucial for financial planning, investment decisions, and retirement savings. It helps investors see how their money can grow over time and emphasizes the importance of starting early with investments.

4. Using the Calculator

Tips: Enter the principal amount in pounds, annual interest rate as a percentage, number of compounding periods per year, 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.

Q2: How does compounding frequency affect returns?
A: The more frequently interest is compounded, the higher the returns will be due to interest being calculated on interest more often.

Q3: What are typical compounding frequencies?
A: Common frequencies include annually (1), semi-annually (2), quarterly (4), monthly (12), and daily (365).
