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; 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.

Decoding your CTC: why in-hand is so much less
Cost to company is what employing you costs, not what you are paid. The four layers inside a CTC, where EPF and gratuity actually go, and the basic-salary split that silently sets three benefits at once.
Old vs new tax regime: the choice that decides everything else
The new regime is the default and usually the winner — but not always. Where the break-even sits, why the §87A rebate never touches capital gains, and why the regime decides whether ELSS, HRA and 80D planning are worth anything at all.
Advance tax and TDS: how India collects before you file
TDS is a running prepayment, not the final bill, and advance tax fills the gap in four dated instalments. The 15/45/75/100 calendar, the cliff in the early triggers, and the presumptive shortcut that collapses it to one March payment.
ESOPs, RSUs and ESPPs: taxed twice, at two different prices
Slab tax on the discount when shares become yours, capital gains from that day's FMV when you sell. Why tax can fall due on paper value, and why the cost-basis error is the most common mistake in self-filed returns with equity comp.
Freelancing full-time: the 50% deal most professionals miss
Presumptive taxation lets a qualifying professional declare half of gross receipts as profit — no books, no audit, one advance-tax instalment. How the scheme works, and how to compare a salary and a freelance offer honestly.
How an EMI actually works (and the flat-rate trick)
Interest on the outstanding balance first, principal with the remainder — so early years barely repay anything. Why tenure sets total interest, why early prepayment punches above its weight, and why a flat rate is roughly double what it claims.
A surplus and a loan: prepay, refinance or invest?
Prepayment is a guaranteed, tax-free return equal to your loan rate — cut the tenure, not the EMI. When a balance transfer clears its fees, and when investing the surplus honestly beats both.
Rent vs buy: the honest math
Terminal net worth on two fully-specified paths, with the renter investing every rupee the buyer sinks. The two assumptions that decide the answer, and the tax change that flipped older calculators' verdicts.
Insurance is not an investment: term plans and the LIC question
Bundled policies do both jobs badly. Sizing a term cover from needs rather than folklore, and evaluating an endowment you already own on forward numbers alone — surrender, paid-up or continue.
What trading actually costs: beyond zero brokerage
STT, exchange charges, GST, stamp duty and DP fees stack on every trade no broker can waive. The break-even move to know before a trade, the averaging-down trap, and what leverage really multiplies.
Running a small business by the numbers
Break-even and the margin of safety, margin versus markup, the cash conversion cycle, the DSCR a lender will compute anyway, and GST as an input-credit chain — the five checks that catch trouble early.
