Overview

The Future Value Calculator helps you project the growth of your investments or savings over time by accounting for compound interest, regular contributions, and varying compounding frequencies.

When to Use

  • Comparing how different compounding frequencies impact your total returns.
  • Determining the potential growth of a lump sum investment with additional periodic deposits.

How It Works

  • Enter your initial investment amount as the Present Value.
  • Specify the annual interest rate and the total number of years for the investment.
  • Select the compounding frequency and indicate if you are making regular contributions.
  • Calculate the result to see the projected future value of your capital.

Use Cases

FAQ

What is compound interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods.

How does compounding frequency affect my returns?

More frequent compounding (e.g., daily vs. annually) generally results in a higher future value because interest is earned on interest more often.

Can I include regular monthly contributions?

Yes, you can enter a regular contribution amount and choose whether these payments occur at the beginning or end of each period.

Is the interest rate fixed?

This calculator assumes a constant annual interest rate throughout the entire duration of the investment.

What is the difference between beginning and end of period contributions?

Beginning of period contributions earn interest for the full duration of the period, while end of period contributions do not earn interest until the following period.
