Compounding Interest Calculator

You can use this calculator to see how a hypothetical investment can grow over the time. For example check out what will happen after 300 months (that’s 25 years) if you invest $250 per month in stock with average return of just 1% per month. You may be surprised by the result.

This investment calculator is for demonstrative purpose only. You should not rely that any investment will bring a fixed return over a long period of time! Use the results to plan your portfolio but don’t get obsessed by the idea to hunt for very high ROI.  The compounding feature in this calculator illustrates in a great way how compounded interest adds with the time, but you should never forget the risks that any kind of investing carries.
