Compounding is one of the main reasons small monthly habits can turn into large long-term balances.
Compounding happens when you earn returns not just on your original money, but also on the returns you already earned in earlier periods.
That means the same contribution schedule can produce very different outcomes depending on how long it runs.
Early years often feel slow because the balance is still small. Later years can accelerate dramatically because the base is larger.
This is why many long-term projections show a curve rather than a straight line.
When you add money regularly, you are not relying only on the return rate. You are building the base that future returns can compound on.
That is one reason a consistent savings or investment habit can matter more than trying to pick a perfect time to begin.
