The small savings family: PPF, SSY, NSC, KVP, SCSS and kin

Behind the post-office counter sits a family of nine-odd schemes that hold more Indian household savings than the entire mutual fund industry did until recently. They share one parent — the National Small Savings Fund — one guarantee (sovereign), and one pricing mechanism: rates notified quarterly by the Ministry of Finance. Treat them as a family and the confusing catalogue collapses into three questions: who is it for, how is it taxed, and how long is the lock-in?

The catalogue, sorted

The compounders grow quietly until maturity:

• PPF — 15 years, ₹1.5 lakh a year, 7.1% currently, and the crown jewel of tax treatment: exempt on contribution (old regime, via 80C), accrual and withdrawal alike. The 15-year term is the price.
• SSY — for a daughter under ten, currently 8.2% with the same exempt-exempt-exempt treatment; runs to her twenty-first year.
• NSC — five years, interest reinvested and taxed only on the way through; an 80C option with a shorter fuse than PPF.
• KVP — doubles your money in a stated period (115 months at the current 7.5%), encashable after 30 months. No tax break at all; its appeal is pure simplicity.

The income payers convert a corpus into cash flow:

• SCSS — for those 60 and over, quarterly payouts at the family's best rate, five-year term. The first stop for retirement corpus before anything market-linked.
• POMIS — monthly interest on a deposit, for income without an age gate.

The bank-adjacent — FD and RD — and APY, a defined-benefit pension for unorganised-sector workers, round out the family.

The two honest caveats

Interest is mostly taxable at slab. Outside the exempt trio (PPF, SSY, and EPF from the salary world), interest from NSC, KVP, SCSS, POMIS, FDs and RDs is ordinary income. At the 30% slab, a 7.5% instrument yields about 5.25% after tax — often below lived inflation, which is the quiet way a savings-shaped asset loses purchasing power. The after-tax column, not the brochure rate, is the comparison that matters — the same discipline as FDs versus debt funds.

The guarantee is real; the growth is capped. These instruments are where money that must not fluctuate belongs — the emergency reserve's fixed leg, a goal due in three years, a retiree's income floor. They are not a substitute for growth assets over decades; the comparison is worked through honestly in ELSS vs PPF and mutual funds vs fixed deposits, and the blending question in goal-based investing.

Using the family well

The strong pattern: match the scheme to the job, not to the rate. PPF and SSY for the long, tax-free compounding floor — each has its own deep dive in PPF and Sukanya Samriddhi; SCSS and POMIS to build a retiree's income base beneath a SWP; NSC for old-regime 80C money that cannot wait fifteen years; FD and RD for parking, not growing.

⚠️ Every rate above is the notified figure for the current quarter (Q2 FY 2026-27 at review) and is revised every three months; caps and eligibility move too. Verify the current notification before investing — WealthTicker is not a SEBI-registered investment adviser.

Key takeaway

Small savings schemes are one sovereign family priced quarterly — pick by job, tax treatment and lock-in rather than chasing a headline rate. PPF and SSY earn their place through exempt-exempt-exempt compounding, SCSS and POMIS through guaranteed income, and everything taxed at slab should be judged on its after-tax yield, which is usually several points less impressive than the poster.
