Investment Growth Calculator: See Compound Growth
See how a steady monthly amount can compound over time. Returns are never guaranteed, so try a few different rates.
How to read the result
The gold part of each bar is money you put in. The green part is growth on top of it. Early on, almost all of the balance is your own money. Over longer periods, growth can become the larger share. That's compounding, and it's why starting small and early matters.
This calculator assumes the same return every year, compounded monthly. Real investments go up and down, and taxes, fees and inflation reduce what you keep. Use it to compare scenarios, not to predict a number. It's education, not investment advice.
