The Power of Compounding

psychology Why Time Matters

Compound interest works like a snowball. At first, the growth is slow because your interest is small. But as your balance grows, the interest itself starts earning interest. Over long periods, the interest portion of your wealth will eventually exceed your original contributions.

"Compound interest is the eighth wonder of the world."

What is compound interest and why does it matter?expand_more

Compound interest is the snowball effect of earning interest on your initial principal as well as on previously accumulated interest. Over long periods (10, 20, or 30 years), compounding allows your wealth to grow exponentially faster than simple savings.

How much should I contribute each month toward my savings goals?expand_more

A standard benchmark is the 50/30/20 budget framework, where at least 20% of your net income is allocated toward savings, emergency funds, and investments. Even small monthly amounts (e.g. $100–$250/mo) create substantial balances through compounding.

What interest rate or expected return should I enter?expand_more

For guaranteed, liquid savings (such as High-Yield Savings Accounts or Certificates of Deposit), rates generally hover around 4% to 5%. For long-term stock market index funds, a historic nominal return of 7% to 10% before inflation is typically modeled.

Is it better to keep money in savings or invest it?expand_more

Keep short-term funds (3-6 months of living expenses for emergencies and goals under 3-5 years) in safe high-yield savings accounts. Direct long-term funds (5+ years horizon) toward diversified investments to outpace inflation and maximize compound wealth.
