Pick a starting amount, a monthly contribution, an assumed growth rate, and a number of years, and watch how the balance could build. The rate is an assumption you choose for illustration, not a predicted or guaranteed return. Then see the cost of waiting: what starting a few years later, on the same assumptions, would leave on the table.
Putting in $65,000 over 20 years could grow to about $114,718 if it earned a steady 5% every year. That puts roughly $49,718 of the total down to growth rather than deposits. Waiting 5 years to start, then running to the same end date, would leave about $38,117 less. The early years do a lot of the work, because they have the longest to compound.

| 6 | $23,000 | $4,570 | $27,570 |

The gold bar shows the share of each year’s balance that is growth rather than money you put in, 43% by the final year.
