What is Compound Interest?

Compound interest means you earn interest on your interest — not just your initial amount. Over time, this creates an exponential snowball effect that dramatically multiplies your wealth.

The Rule of 72

Divide 72 by your interest rate to estimate how many years it takes to double your money.

At 7% interest, your money doubles every ~10 years.

💡 Pro Tips

• Start as early as possible — time is your biggest asset.

• Even small monthly contributions make a massive difference over decades.

• The S&P 500 has historically returned roughly 7–10% annually before inflation over long periods, although future returns are not guaranteed.
