1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of a savings account by accounting for interest earned on both the initial principal and the accumulated interest from previous periods. It's essential for understanding how savings grow over time with UK's best interest rates.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

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

Explanation: The formula calculates how your savings grow with compound interest, which is interest calculated on both the initial principal and the accumulated interest from previous periods.

3. Importance of Savings Interest Calculation

Details: Understanding compound interest is crucial for financial planning, comparing savings accounts, and maximizing returns on your investments with the best UK interest rates.

4. Using the Calculator

Tips: Enter principal amount in GBP, annual interest rate as a decimal (e.g., 0.05 for 5%), compounding frequency per year, and time period in years. All values must be positive numbers.
