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 an accelerating rate over time, making it a powerful tool for long-term financial planning.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Final amount including interest (£)
\( P \) — Principal investment amount (£)
\( R \) — Annual interest rate (%)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The more frequently interest is compounded, the greater the final amount will be due to interest being earned on interest.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for effective savings and investment planning. It demonstrates how regular savings can grow significantly over time, especially when starting early and allowing interest to compound frequently.

4. Using the Calculator

Tips: Enter the principal amount in pounds, annual interest rate as a percentage, select compounding frequency, 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 my savings?
A: More frequent compounding (e.g., monthly vs annually) results in higher returns because interest is calculated and added to the principal more often.

Q3: Are UK savings accounts taxed?
A: In the UK, you may have a Personal Savings Allowance. Basic rate taxpayers can earn £1,000 in savings interest tax-free, while higher rate taxpayers have a £500 allowance.

Q4: What's a typical interest rate for UK savings accounts?
A: Interest rates vary by account type and economic conditions. As of 2024, typical rates range from 1-5% for standard savings accounts.

Q5: Should I choose an account with higher compounding frequency?
A: Generally yes, but also consider other factors like interest rate, accessibility, and account fees when choosing a savings account.
