1. What is the Future Value Formula?

The Future Value formula calculates the value of UK savings over time with compound interest and regular contributions. It helps visualize savings growth through graphing to plan financial goals effectively.

2. How Does the Calculator Work?

The calculator uses the Future Value formula:

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

Where:

\( FV \) — Future value (GBP)
\( P \) — Initial principal (GBP)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of compounding periods per year
\( t \) — Time in years
\( PMT \) — Periodic payment (GBP per period)

Explanation: The formula accounts for compound interest on both the initial principal and regular contributions, showing how savings grow over time.

3. Importance of Future Value Calculation

Details: Calculating future value is crucial for financial planning, retirement savings, investment decisions, and understanding how compound interest accelerates wealth accumulation over time.

4. Using the Calculator

Tips: Enter initial principal in GBP, annual interest rate as decimal (e.g., 0.05 for 5%), compounding frequency, time in years, and periodic payment amount. All values must be valid and non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest calculates earnings only on the principal, while compound interest calculates earnings on both principal and accumulated interest, leading to faster growth.

Q2: How does compounding frequency affect savings?
A: More frequent compounding (e.g., monthly vs. annually) results in higher returns due to interest being calculated and added more often.

Q3: What are typical compounding periods?
A: Common periods include annually (1), semi-annually (2), quarterly (4), monthly (12), or daily (365).

Q4: Can this calculator handle regular contributions?
A: Yes, the PMT parameter allows for regular contributions to be included in the future value calculation.

Q5: Is this suitable for all UK savings accounts?
A: This calculator works for most savings vehicles including ISAs, fixed-rate bonds, and regular savings accounts with compound interest.
