Why time matters so much
Your money earns a return. Then that return earns a return too. That's compounding.
In the early years, most of your balance is money you put in. Give it enough time and the growth can end up bigger than everything you added. Watch the gold part of the chart. It starts small. Then it takes over.
That's why starting early, even with a smaller amount, often beats starting big later.
Keep this in mind
- Real markets don't grow the same amount every year. Some years are great. Some years go down. This uses one steady rate, so treat it as a rough guide.
- It doesn't count taxes, fees, or rising prices. To see a result closer to today's dollars, try a lower return rate.
- "Compound" sets how often growth gets added. If your rate is a yearly return, leave it on Annually. If a bank quotes a rate that compounds monthly or daily, pick that one.
