Future Value Calculator
Calculate future value of investments
About the Future Value Calculator
Money today is worth more than the same money later, and the Future Value Calculator shows exactly how much more. Enter a present sum, an interest rate, and a time horizon, and it projects what that money will grow to with compounding — optionally adding a regular monthly deposit along the way.
Savers use it to see where a nest egg lands in ten years; planners use it to test whether a savings habit reaches a goal. The compounding-frequency control lets you model daily, monthly, quarterly, or annual compounding on a lump sum, while the monthly-deposit option layers in steady contributions for a more realistic savings picture. Because contributions and interest are reported separately, it also doubles as a reality check on how much of a projected balance is genuinely growth rather than your own deposits.
How to Use the Future Value Calculator
- Enter the present value — the amount you are starting with.
- Enter the annual interest rate and the time period in years.
- Choose a compounding frequency (daily, monthly, quarterly, or annually) for the lump sum.
- Optionally add a monthly deposit to model regular contributions.
- Read the projected future value, total contributions, and total interest earned, then Copy the result.
Why Use ToolForge’s Future Value Calculator
- It models both a one-time lump sum and ongoing monthly deposits, so you can project realistic savings, not just idle capital.
- Four compounding frequencies let you match how your account actually compounds, which changes the result more than people expect.
- It separates total contributions from total interest, making it clear how much growth came from your money versus from compounding.
- It runs entirely client-side with no sign-up, so your financial figures stay private.
Frequently Asked Questions
What is future value?
Future value is what a sum of money today will be worth at a later date once interest or returns have compounded. It is the core idea behind savings growth: a dollar invested now becomes more than a dollar later because it earns on itself over time.
Why does compounding frequency change the result?
The more often interest is compounded, the sooner earned interest starts earning its own interest. Daily compounding produces slightly more than annual compounding at the same rate, because growth is credited and reinvested more frequently.
What happens when I add a monthly deposit?
The calculator then treats your contributions as a monthly series compounded over the full term, on top of the growth of your starting balance. This models a regular savings habit rather than a single deposit left to grow.
