The orange portion of each bar is the money you put in. The green portion is the hypothetical growth on top of it. Early on the bar is almost all contributions; the longer the time horizon, the more the green compounding portion tends to take over. That shift is the whole point of starting early, and it is easier to feel by sliding the inputs than by reading about it.
This is an illustration built on a single, constant assumed return. Real markets do not move in a straight line, and this tool is for learning, not for predicting your actual balance.
You enter your current age, the age you want to target, what you have saved now, how much you add each month, and an assumed annual return. The calculator compounds your balance month by month and shows a hypothetical total, split into what you contributed versus growth from returns.
There is no "correct" number, and this tool does not recommend one. Many people run a few scenarios with different rates to see how sensitive the result is. Real returns vary year to year and are never guaranteed, so treat any single number as an illustration, not a forecast.
No. This is a simplified illustration that leaves out taxes, fees, withdrawals, and inflation so the effect of compounding is easy to see. Your real results will differ. For decisions that matter, consider talking to a qualified financial professional.
