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:

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

Where:

\( FV \) — Future Value of the investment (GBP)
\( P \) — Principal investment amount (GBP)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of compounding periods per year
\( t \) — Time the money is invested for (years)

Explanation: The more frequently interest is compounded, the greater the return on your savings, as each interest payment is added to the principal for the next calculation.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for long-term savings and investment planning. It demonstrates how regular savings can grow significantly over time, especially when starting early.

4. Using the Calculator

Tips: Enter your initial deposit in GBP, the annual interest rate as a percentage, select how often interest is compounded, and the number of years you plan to save. 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 the principal plus any accumulated interest.

Q2: How often do UK banks typically compound interest?
A: Most UK savings accounts compound interest annually, but some offer monthly or daily compounding which can yield higher returns.

Q3: Are savings account interest rates fixed or variable?
A: This varies by account type. Fixed-rate bonds offer a set rate for a term, while easy-access accounts typically have variable rates that can change.

Q4: Is compound interest taxable in the UK?
A: Interest earned on savings may be subject to tax, but most UK residents have a Personal Savings Allowance allowing some tax-free interest income.

Q5: What's the best way to maximize compound interest?
A: Start early, save regularly, choose accounts with higher interest rates and more frequent compounding, and avoid withdrawing funds to allow interest to compound.
