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 over time compared to simple interest, making it a powerful concept for long-term investments like Lifetime ISAs.

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 (currency units)
\( P \) — Principal amount (currency units)
\( R \) — Annual interest rate (%)
\( n \) — Compounding frequency per year
\( T \) — Time in years

Explanation: The formula calculates how much an investment will grow over time when interest is compounded at regular intervals.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is crucial for financial planning, especially for long-term savings vehicles like Lifetime ISAs. It helps investors see how their money can grow over time and make informed decisions about savings and investments.

4. Using the Calculator

Tips: Enter the principal amount in currency units, annual interest rate as a percentage, compounding frequency (how many times per year interest is compounded), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a Lifetime ISA?
A: A Lifetime ISA (Individual Savings Account) is a UK government-backed savings account that allows you to save up to £4,000 each year, with the government adding a 25% bonus on top of your savings.

Q2: How often is interest typically compounded in ISAs?
A: Most ISAs compound interest annually, but some may compound monthly, quarterly, or daily. Always check with your specific provider.

Q3: Can I withdraw from a Lifetime ISA at any time?
A: Withdrawals from a Lifetime ISA are generally for buying your first home or after age 60. Other withdrawals may incur a penalty.

Q4: How does compound interest benefit long-term savings?
A: Compound interest allows your savings to grow exponentially over time, as you earn interest on both your initial investment and the accumulated interest.

Q5: What's the difference between compound interest and simple interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus any accumulated interest.
