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's often referred to as "interest on interest" and can cause wealth to grow exponentially over time.

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 (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Number of years the money is invested/borrowed

Explanation: The formula calculates how much your investment will grow over time with compound interest, based on Bank of England interest rates.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning, savings strategies, and investment decisions. It demonstrates how money can grow over time and why starting to save early is beneficial.

4. Using the Calculator

Tips: Enter the principal amount in pounds, annual interest rate as a percentage (based on Bank of England rates), number of compounding periods per year, and time period in years. All values must be positive numbers.
