1. What is the Future Value Formula?

The future value formula calculates the value of an investment or savings at a future date, taking into account compound interest and regular contributions. It helps individuals plan for retirement and long-term financial goals.

2. How Does the Calculator Work?

The calculator uses the future value 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 value (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 accounts for both the initial investment growth through compound interest and the accumulated value of regular contributions.

3. Importance of Future Value Calculation

Details: Calculating future value is essential for retirement planning, savings goals, and understanding how investments grow over time with compound interest.

4. Using the Calculator

Tips: Enter initial amount in GBP, annual growth rate as a decimal (e.g., 0.05 for 5%), compounding periods per year, time in years, and periodic contribution in GBP. All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest.

Q2: How does compounding frequency affect future value?
A: More frequent compounding results in higher future values because interest is calculated more often.

Q3: What is a typical annual growth rate for pensions?
A: This varies widely but typically ranges from 3-7% annually for balanced investment portfolios.

Q4: Can I use this for monthly contributions?
A: Yes, set n=12 for monthly compounding and enter your monthly contribution amount.

Q5: How accurate are these calculations?
A: These are mathematical projections assuming constant returns. Actual results may vary due to market fluctuations.
