What is the future value calculator?

In short

Future value (FV) is what a sum of money will be worth at a future date given a rate of return. For a single amount, FV = P × (1 + r)^t. When you also make regular deposits, the future value of those contributions is added on top. KalkWise computes both together for any contribution frequency.

This future value calculator tells you what an investment or savings plan will be worth at a future date. It combines the growth of your starting amount with the future value of all your periodic contributions.

How to use this calculator

  1. 1Enter the present amount you're starting with.
  2. 2Add periodic contributions and their frequency, if any.
  3. 3Set your expected annual rate of return and compounding frequency.
  4. 4Enter the time horizon in years and months.
  5. 5Read the future value and the contributions-vs-growth split.

The formula

FV=P(1+rn)nt+PMT×[(1+rn)nt−1rn]
The first term grows your starting amount; the second term adds up the future value of every contribution. Together they give your final balance.
FV
— Future value (final balance)
P
— Starting principal
PMT
— Periodic contribution
r
— Annual interest rate (decimal)
n
— Compounding periods per year
t
— Number of years

KalkWise simulates each month individually so that contributions, compounding frequency, and partial years are all handled precisely.

Worked example

The scenario

Invest $5,000 today, add $300 monthly, earn 8% compounded monthly, for 15 years.

gives

The result

The future value is about $134,000, of which roughly $59,000 is money you put in and ~$75,000 is investment growth.

Common use cases

  • Estimating what an investment will be worth at a target date
  • Planning for a down payment, tuition, or large purchase
  • Comparing lump-sum vs. regular investing
  • Valuing the long-term payoff of starting to invest earlier

Limitations & assumptions

  • Uses a single assumed rate; markets fluctuate and returns are not guaranteed.
  • Does not include taxes, fees, or fund expense ratios.
  • Future value is in nominal terms — inflation reduces real purchasing power.

Frequently asked questions

Future value is the projected worth of money at a future date, based on an assumed rate of return and time horizon.
