2. How Does the Calculator Work?

The calculator uses the UK Monthly Savings Formula:

\[ FV = P \times (1 + r / 12)^{12 \times t} + PMT \times \left[ \frac{(1 + r / 12)^{12 \times t} - 1}{r / 12} \right] \]

Where:

\( FV \) — Future Value (GBP)
\( P \) — Initial Principal (GBP)
\( r \) — Annual Interest Rate (decimal)
\( t \) — Time in Years (years)
\( PMT \) — Monthly Payment (GBP per month)

Explanation: The formula calculates compound interest on both the initial principal and regular monthly contributions, providing a comprehensive view of savings growth.
