Investors aiming for ₹10 lakh by 2028 have a key decision: Systematic Investment Plans (SIPs) or Recurring Deposits (RDs). RDs offer safety and guaranteed returns (3-8.5%) but require a higher monthly investment of approximately ₹25,200 at 6.5% interest. SIPs, though market-linked and carrying risk, could potentially achieve the goal with a lower monthly investment of around ₹23,300 at a 12% average return, leveraging compounding for faster growth. The choice depends on risk tolerance versus certainty.
