Future Value Formulas

The calculator uses the following formulas to compute future value:

  • Future Value of Starting Amount:

    • \[ FV = PV \times (1 + I/Y)^N \]

  • Future Value of Periodic Deposits:

    • \[ FV = PMT \times \frac{(1 + I/Y)^N - 1}{I/Y} \times (1 + I/Y)^\text{Timing} \]

    Note: For deposits made at the beginning of each period, Timing = 1. For deposits made at the end of each period, Timing = 0.

Frequently Asked Questions (FAQ)

1. What is the future value of an investment?

Future value is the total amount an investment will grow to over time, taking into account factors like starting value, periodic contributions, interest rate, and compounding periods.

2. What does "PMT made at the beginning or end of each period" mean?

This refers to when periodic deposits are made. Deposits made at the beginning of a period grow for an additional compounding period, which increases the future value.

3. Can I use this calculator for retirement planning?

Yes! The Future Value Calculator is great for retirement planning, savings goals, and evaluating investment options. It helps you see how your contributions will grow over time.

4. How is the interest calculated?

Interest is calculated based on the compounding of the starting amount and periodic deposits over the specified number of periods using the interest rate provided.

5. Why are there graphs and pie charts?

Graphs and pie charts give a visual representation of your investment growth, making it easier to analyse the contributions of principal, deposits, and interest.
