1. What Is The Future Value Formula?

The future value formula calculates how much regular savings will be worth in the future, taking into account compound interest. It's particularly useful for evaluating regular saver accounts and other savings products.

2. How Does The Calculator Work?

The calculator uses the future value of annuity formula:

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

Where:

\( FV \) — Future Value (GBP)
\( PMT \) — Periodic Payment (GBP per period)
\( r \) — Annual Interest Rate (decimal)
\( n \) — Compounding Periods Per Year (unitless)
\( t \) — Time in Years (years)

Explanation: This formula calculates the accumulated value of regular payments with compound interest, showing how savings grow over time.

3. Importance Of Regular Saving

Details: Regular saving with compound interest can significantly grow your wealth over time. Understanding future value helps in financial planning and comparing different savings products.

4. Using The Calculator

Tips: Enter the regular payment amount in GBP, annual interest rate as a decimal (e.g., 0.05 for 5%), number of compounding periods per year, and time in years. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between annual and monthly compounding?
A: Monthly compounding (n=12) results in slightly higher returns than annual compounding (n=1) due to more frequent interest calculations.

Q2: How does payment frequency affect future value?
A: More frequent payments (e.g., monthly vs annually) generally lead to higher future values due to earlier compounding.

Q3: What is a good interest rate for regular savings?
A: This varies by economic conditions, but typically rates above inflation (2-3%) are considered good for preserving purchasing power.

Q4: Are there tax implications on savings interest?
A: In the UK, you may need to pay tax on savings interest above your Personal Savings Allowance, depending on your income tax band.

Q5: How accurate is this calculator for real-world savings?
A: This provides a theoretical calculation. Actual returns may vary due to changing interest rates, fees, or account terms.
