Investment planning involves balancing risk and return. Lower risk investments like savings accounts and fixed deposits have lower potential returns, while higher risk investments like equity and real estate may offer higher returns but more volatility. Different investment options suit different goals based on risk tolerance and time horizon. Cash management involves saving programs, budgeting, and using appropriate products like FDs, RDs, and money market instruments. Bonds, mutual funds, PPF, and tax-free bonds are good options for debt investments suitable for medium-term goals. Equity is best for long-term goals due to higher potential returns over long periods.
