NSC (National Savings Certificate) is a 5-year, fixed-interest instrument that compounds annually and pays out the full accumulated amount at maturity, with the invested amount (up to ₹1.5 lakh) eligible for Section 80C deduction. It suits a medium-term, guaranteed-growth goal where you don't need income along the way.
KVP (Kisan Vikas Patra) is built around a simple promise: your money doubles over a fixed period (currently around 115 months, subject to change with rate revisions) at the prevailing interest rate, with no 80C benefit and interest that's fully taxable. It suits someone who wants a straightforward doubling target without needing the tax deduction.
POMIS (Post Office Monthly Income Scheme) is built for income, not growth — a lumpsum deposit up to a specified limit pays a fixed monthly interest amount over a 5-year tenure, useful for someone who wants a predictable monthly cash flow, like a retiree, rather than a lump sum at the end.
