How the Sukanya Samriddhi Yojana works
Sukanya Samriddhi Yojana is a government-backed savings scheme built around one specific goal: a girl child’s education and marriage. A parent or guardian can open an account for a daughter below 10 years of age at any post office or authorised bank, and a family can hold at most two accounts — one each for two daughters. At 8.2%, the current rate is the highest of any small savings scheme, comfortably above PPF, and it compounds annually.
The timeline is what makes SSY unusual. You deposit for the first 15 years from opening, anywhere between ₹250 and ₹1,50,000 per financial year. The account then keeps running — and keeps earning the full rate — for another 6 years, maturing 21 years after opening. Those interest-only years from 16 to 21 do a surprising amount of the heavy lifting, because by then the balance is large and every year of compounding adds lakhs, not thousands.
The whole thing is EEE, the cleanest tax status available: deposits qualify for a Section 80C deduction under the old regime, the interest earned is exempt every year, and the entire maturity amount lands tax-free. There is no other guaranteed instrument in India that pays 8.2% with zero tax at every stage.
What ₹1,00,000 a year grows into
Put in ₹1,00,000 every year for 15 years and you will have contributed ₹15,00,000 of your own money. At the current 8.2% rate, the account matures at roughly ₹47,88,079 in year 21 — about ₹32,88,079 of that is interest, and every rupee of it is tax-free. In other words, the scheme more than triples your money, and over two-thirds of the final corpus is growth rather than your deposits.
The maturity value scales in a straight line with the deposit, so it is easy to translate to your own number: the full ₹1,50,000 a year matures at about ₹69,27,578, while ₹50,000 a year gives you around ₹23,09,193. One practical tip — deposit early in the financial year, ideally in April. A deposit made in April earns interest for the whole year; the same deposit made in March earns almost nothing for that year, and over 15 deposits that timing difference genuinely adds up.
| Yearly deposit | ₹1,00,000 |
| Total deposited over 15 years | ₹15,00,000 |
| Value at maturity (year 21) | ≈ ₹47,88,079 |
| Tax-free interest earned | ≈ ₹32,88,079 |
Withdrawals, maturity and the rules that matter
The lock-in is real, but it loosens exactly when the money is likely to be needed. Once the girl turns 18, you can withdraw up to 50% of the balance for her higher education or marriage — enough to cover admission fees and early college costs while the rest keeps compounding. Full premature closure is permitted at her marriage after she turns 18, so the account does not have to run the entire 21 years if life moves faster.
Note that the deposit window and the maturity date are both anchored to the opening date, not the girl’s age. Open the account when she is 2, and deposits run until she is 17 and maturity arrives at 23. Open it at age 9 and maturity lands at 30 — though the education withdrawal at 18 covers the years in between. This is a good argument for opening the account as early as possible: you start the 21-year clock sooner and buy more compounding years at a rate no bank FD matches.
SSY vs PPF vs an equity SIP for your daughter
Against PPF, SSY wins on rate and matches it on taxation — both are EEE, but SSY currently pays 8.2% versus PPF’s lower rate, and both cap deposits at ₹1,50,000 a year. PPF’s advantages are flexibility: anyone can open one, it matures in 15 years, and it can be extended indefinitely. If the money is unambiguously for a daughter under 10, SSY is the better vehicle; many families sensibly run both, using PPF for their own goals.
An equity SIP is the honest alternative worth weighing. Over an 18-to-21-year horizon, a diversified equity fund has historically had a good chance of beating 8.2%, but with no guarantee and real swings along the way, and gains are taxable. SSY’s return is government-guaranteed and tax-free, which makes it an excellent core holding for the goal — a common approach is to lock in the safety with SSY and add a smaller SIP on top for upside, rather than choosing one and abandoning the other.
One caveat on the rate itself: 8.2% is not contractual for 21 years. The government resets small savings rates every quarter, and your balance earns whatever the prevailing rate is. The slider above lets you test more conservative assumptions — even at 7.6%, the structure of 15 deposit years plus 6 growth years still produces a substantial tax-free corpus.
