Free Investment Growth Calculator

Project investment growth with contributions, fees and inflation over many years.

The starting amount and monthly contributions, which can rise yearly, are compounded monthly at the expected return minus annual fees. Inflation is then used to show the final balance in today's money, along with total invested and growth.

How to use the Investment Growth Calculator

  1. Enter your starting amount, regular contribution, expected return and time period.
  2. Read the end value and the split between money you put in and growth.
  3. Try a lower return as well as a higher one, because real markets are uneven.

About the Investment Growth Calculator

Project investment growth with contributions, fees and inflation over many years.

Time and consistency do most of the work in saving and investing. Running the numbers shows how small changes in rate, term or contribution add up.

Getting started with the Investment Growth Calculator

Using the investment growth calculator takes a minute or two. Your entries are saved in this browser, so you can come back later and carry on.

Tips for better results

Even small fees compound over decades, so compare the result with fees at zero. Plan using the inflation-adjusted balance, and try lower returns for a cautious case.

Treat the result as an illustration, not a promise. Returns vary year to year.

Fees and inflation reduce real growth, so consider both when planning.

Is the return guaranteed?
