1. What is the Future Value Formula?

The future value formula calculates how much your retirement savings will be worth at a future date, taking into account compound interest and regular contributions. It helps you plan for your financial goals by age.

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 value at retirement
$ P $ — Initial investment amount
$ r $ — Annual interest rate (as decimal)
$ n $ — Number of compounding periods per year
$ t $ — Time to retirement in years
$ PMT $ — Regular contribution amount per period

Explanation: The formula calculates both the growth of your initial investment and the accumulated value of your regular contributions over time.

3. Importance of Retirement Planning

Details: Proper retirement planning ensures financial security in your later years. Understanding compound interest helps you make informed decisions about savings rates and investment strategies to meet your retirement goals by specific ages.

4. Using the Calculator

Tips: Enter your current savings, expected annual return, compounding frequency, years until retirement, and regular contribution amount. Use realistic growth rates (typically 5-8% for diversified investments).

5. Frequently Asked Questions (FAQ)

Q1: What's a good retirement savings target by age?
A: General guidelines suggest 1x salary by 30, 3x by 40, 6x by 50, and 8-10x by retirement age.

Q2: How often should I compound my investments?
A: More frequent compounding (monthly vs annually) yields slightly higher returns due to compounding effect.

Q3: Should I increase contributions over time?

Q4: What inflation rate should I consider?
