Consistency matters: Small monthly additions often beat a larger initial sum over time.
💡
High frequency helps: Daily or monthly compounding earns more than annual compounding.
💡
Reinvest always: Make sure to reinvest your interest to maximize the effect.
💡
Watch the fees: Even small expense ratios can eat 20-30% of your long-term growth.
