Common questions
Investment Growth Calculator FAQs
How is investment growth calculated?＋
Your starting balance grows at the assumed monthly equivalent of the annual return. Each contribution is then added and participates in future growth.
Does the result include inflation?＋
Yes. The main projection is nominal, and the results also show an inflation-adjusted value in today’s money.
Are investment returns guaranteed?＋
No. This is an illustrative projection, not a forecast or financial advice. Actual returns can be lower or negative.
