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 a powerful concept that allows savings to grow faster over time compared to simple interest, where interest is calculated only on the principal amount.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( FV \) — Future Value (GBP)
• \( P \) — Principal Amount (GBP)
• \( r \) — Annual Interest Rate (decimal)
• \( n \) — Number of compounding periods per year
• \( t \) — Time in years

Explanation: The formula calculates how much your savings will grow based on your initial deposit, interest rate, compounding frequency, and time period.

3. Importance of Savings Calculations

Details: Understanding compound interest helps in financial planning, setting savings goals, and making informed decisions about where to place your money for optimal growth. It demonstrates how regular savings can significantly increase over time.

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 time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q4: How can I get the best savings rate?
A: Shop around different banks and building societies, consider fixed-term accounts for higher rates, and regularly check as rates change frequently.
