1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or pension pot by accounting for both the initial principal and the accumulated interest over time, including regular contributions.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( FV \) — Future pension pot (GBP)
\( P \) — Initial amount (GBP)
\( r \) — Annual growth rate (decimal)
\( n \) — Compounding periods per year (unitless)
\( t \) — Time in years (years)
\( PMT \) — Periodic contribution (GBP per period)

Explanation: The formula calculates how your pension pot grows over time through compound interest and regular contributions.

3. Importance of Pension Planning

Details: Proper pension planning using compound interest calculations helps individuals understand how their savings can grow over time, ensuring financial security in retirement.

4. Using the Calculator

Tips: Enter all values in the specified units. Ensure the annual growth rate is entered as a decimal (e.g., 5% = 0.05). All values must be non-negative.
