Start investing early to maximize the power of compound interest - time is your greatest asset

Compare interest rates carefully - even a 1% difference can mean thousands more over decades

Choose daily or monthly compounding over annual when possible - frequency matters significantly

Use the Rule of 72: divide 72 by your interest rate to estimate how long it takes to double your money

Always reinvest interest and dividends to maximize compound growth potential

Consider tax-deferred accounts like 401(k)s and IRAs to avoid annual tax drag on compound growth

Factor in inflation when calculating real returns - 6% nominal might only be 3% real return

High-interest debt should be paid off before investing - guaranteed savings often beat uncertain gains

Don't let fees erode your compound interest - even 1% in fees can cost thousands over time

Automate regular investments to dollar-cost average and harness compound growth consistently
