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, where interest is calculated only on the principal amount.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + R / n)^{n \times T} \]

Where:

\( A \) — Maturity amount (GBP)
\( P \) — Principal amount (GBP)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The formula calculates how much your savings will grow when interest is compounded at regular intervals.

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, especially when starting early and allowing interest to compound.

4. Using the Calculator

Tips: Enter the principal amount in GBP, 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 returns?
A: More frequent compounding (e.g., daily vs. annually) results in higher returns because interest is calculated and added to the principal more often.

Q3: Are there tax implications for interest earned?
A: In the UK, interest earned on savings may be subject to tax, though most people have a Personal Savings Allowance. Consult a financial advisor for specific advice.

Q4: Do all UK savings accounts use compound interest?
A: Most do, but terms vary by account type. Always check the specific terms and conditions of any savings account.

Q5: Can I use this calculator for other currencies?
A: While the formula works for any currency, this calculator is specifically formatted for GBP. The principles are the same for other currencies.
