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 faster than simple interest, as you earn interest on your interest over time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Future value of the investment/loan (£)
\( P \) — Principal investment amount (£)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested for (years)

Explanation: The more frequently interest is compounded, the greater the return on your savings investment.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for long-term savings planning. It demonstrates how regular savings can grow significantly over time, making it a powerful tool for retirement planning and wealth building.

4. Using the Calculator

Tips: Enter your initial deposit amount in pounds, the annual interest rate as a percentage, select how often interest is compounded, and the 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 the principal plus accumulated interest.

Q2: How often do UK savings accounts typically compound interest?
A: Most UK savings accounts compound interest annually, but some may compound monthly, quarterly, or daily.

Q3: Does compounding frequency make a big difference?
A: Yes, more frequent compounding results in higher returns. Daily compounding will yield slightly more than monthly, which yields more than annual compounding.

Q4: Are savings interest rates taxable in the UK?
A: It depends on your personal savings allowance and income tax band. Basic rate taxpayers have a £1,000 savings allowance, higher rate taxpayers £500.

Q5: What's a good interest rate for savings in the UK?
A: Rates vary, but competitive easy-access savings accounts typically offer 1-3%, while fixed-term accounts may offer 3-5% depending on the term length.
