When it comes to long-term investing, choosing between Public Provident Fund (PPF) and Systematic Investment Plan (SIP) can be a crucial decision. PPF is a government-backed scheme known for its safety and guaranteed returns, while SIP involves investing in mutual fund schemes, offering potentially higher returns but with market-linked risks. Both options promote disciplined saving and investing, but they differ significantly in terms of risk, return potential, and investment structure. Understanding these differences is key to making an informed decision that aligns with your financial goals and risk tolerance.
