1. What is the Lifetime ISA Compound Interest Formula?

The Lifetime ISA (LISA) compound interest formula calculates the future value of an investment by accounting for the effect of compounding, where interest is earned on both the initial principal and the accumulated interest over time.

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 (unitless)
\( T \) — Time in years

Explanation: The formula demonstrates how money grows over time through the power of compounding, with more frequent compounding periods resulting in higher returns.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is essential for long-term financial planning, retirement savings, and maximizing returns on investments in a Lifetime ISA.

4. Using the Calculator

Tips: Enter the principal amount in currency units, annual interest rate as a percentage, select compounding frequency, and time in years. All values must be positive numbers.
