The Sukanya Samriddhi Yojana was launched by the Government of India in 2015 as part of the “Beti Bachao, Beti Padhao” initiative, aimed at encouraging families to save specifically for a girl child's education and marriage expenses through a dedicated, government-backed instrument. Unlike PPF, which any eligible individual can open for themselves, SSY is purpose-built around a single beneficiary — a girl child — and structured with a longer overall tenure than PPF but a shorter deposit window, reflecting its design intent: front-load contributions during the child's early years, then let the balance compound for a much longer period until she needs the funds around the time of higher education or marriage. The scheme has historically carried a somewhat higher interest rate than PPF, a deliberate incentive to encourage adoption, though both rates move together in response to broader government bond yield trends since they are revised on a similar quarterly cycle.

• Parents and legal guardians of a girl child under 10, planning a dedicated, government-backed savings vehicle for her future education or wedding expenses.
• Grandparents or extended family considering contributing toward an SSY account opened by the child's parents.
• Financial planners comparing SSY against other education-savings options like child-specific mutual fund plans or recurring deposits.
• Families with more than one daughter managing multiple SSY accounts and tracking each child's separate deposit cap and maturity timeline.
• Households setting a savings budget after a birth who want to know how a fixed annual amount, committed now, compounds by the time their daughter reaches college age or marriage age, to size the deposit appropriately against their overall household budget.

Opening an SSY account follows a broadly similar process to PPF: the parent or guardian visits a designated bank branch or post office, completes the account-opening form, submits the girl child's birth certificate along with identity and address proof of the guardian, and makes the minimum opening deposit. Several major banks now also support SSY account opening through net banking or a mobile app for existing customers, which can simplify both the initial opening and the ongoing annual deposits considerably. As with any long-tenure account intended to benefit a child, it is worth keeping the passbook or statement, account number, and registered mobile number or email up to date over the years, since the account will likely outlive several changes of address or bank relationship managers before it matures.

An SSY account can generally be opened by a parent or legal guardian in the name of a girl child who is an Indian resident, at any time from birth up to the age of 10 years, at designated bank branches or post offices. A family is generally permitted to open SSY accounts for a maximum of two girl children, with an exception commonly made for cases of twins or triplets in the second birth. Required documents typically include the girl child's birth certificate, identity and address proof of the parent or guardian, and a passport-sized photograph. As with PPF, eligibility rules have specific edge cases (for example, around adoption or a change in guardianship), so anyone in an unusual situation should confirm directly with the account-holding bank or post office before proceeding.

1. Deposits are made each year for the first 15 years of the account's tenure.
2. Interest is credited annually on the running balance, at the rate applicable for each period.
3. From year 16 through year 21, no further deposits are required, but the accumulated balance continues to earn interest.
4. The balance at the end of year 21 is the maturity value.

This two-phase structure — an active deposit window followed by a longer compounding-only window — is the key mechanical difference between SSY and PPF, and it means a large share of the final maturity value comes from interest earned after deposits have already stopped.

Because deposits stop after 15 years but the account keeps earning interest for another 6 years, a meaningful portion of the eventual maturity value is generated purely through compounding on an already-accumulated balance, with no further cash outlay required from the family. This structure rewards starting the account as early as possible after the child's birth, since an account opened at birth reaches its full 21-year maturity when the child is barely into adulthood, timed well for either higher education or marriage expenses, whereas an account opened closer to the age-10 cutoff reaches maturity when the child is considerably older, which may or may not align as well with the intended use of the funds. Modeling your specific account's year-by-year growth against your daughter's expected milestones — entering college, for instance — is a useful planning exercise beyond just the final maturity number.

• Minimum deposit per financial year: commonly cited as ₹250 to keep the account active.
• Maximum deposit per financial year: commonly cited as ₹1.5 lakh; deposits above this do not earn interest or qualify for tax benefit.
• Deposits required only for the first 15 years; account matures after 21 years total.
• Partial withdrawal typically permitted once the girl turns 18, for higher education expenses, subject to a cap.
• Premature closure generally allowed only in specific circumstances, such as the account holder's death.

As with PPF, every one of these figures is set by government notification and subject to change — confirm the currently applicable minimum, maximum, and withdrawal rules with your bank or post office before making a decision based on them.

SSY has historically shared the same EEE (Exempt-Exempt-Exempt) tax treatment as PPF: deposits have typically qualified for a deduction under the relevant section of the Income Tax Act (subject to an overall combined cap shared with other similar instruments), the interest credited each year has typically been tax-exempt, and the maturity proceeds have typically been fully tax-free. This makes SSY one of the more tax-efficient options specifically available for a girl child's savings, though as always, tax rules can change and eligibility may depend on which tax regime you have chosen for a given financial year — verify current treatment with a tax professional.

Families saving for a daughter's future sometimes use both instruments together — SSY as the dedicated, higher-rate vehicle tied specifically to her milestones, and PPF (in a parent's own name) as a more flexible, general-purpose long-term savings component.

Consider a parent who opens an SSY account for their newborn daughter and deposits ₹₹78,000 every year for 15 years, at an illustrative 13.3% annual rate.

1. Years 1 through 15: each year, ₹₹78,000 is deposited and interest is credited on the growing balance.
2. By the end of year 15, total deposits equal ₹₹11,70,000, with additional accumulated interest on top.
3. Years 16 through 21: no further deposits are made, but the balance continues to compound at the prevailing rate.
4. At maturity (year 21), the balance reaches approximately ₹₹77,41,900, of which about ₹₹65,71,900 is interest — a substantial share of it earned during the post-deposit compounding years alone.

This example illustrates why opening the account as early as possible after birth is one of the single highest-leverage decisions a family can make with SSY — it maximises the number of interest-only compounding years before the funds are needed.

Because SSY funds are typically earmarked for higher education or marriage expenses, it is worth mapping the account's year-by-year projected balance against the family's expected timeline for each milestone, rather than looking only at the final maturity figure at year 21. Partial withdrawal for higher education is typically available once the girl turns 18 (or has passed 10th standard, depending on current rules), which may occur well before the account's full maturity — meaning families planning for a college admission around that age should model the partial-withdrawal-eligible balance separately from the eventual full maturity value. Families targeting marriage-related expenses, by contrast, may prefer to let the account run closer to full maturity (or to the point the account closes automatically upon marriage after age 18) to maximise the compounding benefit. Because these two goals pull in different directions — earlier access for education versus later access for maximum growth — it is worth deciding in advance which goal the SSY account is primarily meant to serve, and using other savings vehicles to cover the other goal if both are a priority.

• Open the account as early as possible after birth to maximise the number of compounding-only years after deposits stop.
• Deposit early in each financial year, similar to PPF, since interest calculation typically favours funds deposited earlier in the year.
• Track the minimum yearly deposit requirement carefully during the 15-year deposit window to avoid the account going into default.
• Plan around the account's maturity timeline relative to your daughter's likely education or marriage timeline, not just the maturity amount in isolation.

• Opening the account later than necessary, losing valuable early compounding-only years at the end of the tenure.
• Assuming deposits are required for the full 21-year tenure, when they are only required for the first 15.
• Missing the minimum yearly deposit during the deposit window and having the account go into default.
• Opening more than the permitted number of SSY accounts across daughters without checking the current family-level limit.
• Assuming the interest rate is fixed for the full tenure, when it is actually revised quarterly by the government.
• Forgetting to update the account's registered contact details over its long life, making it harder to track statements and notices as the years pass.

An SSY calculator projects how deposits made during the first 15 years grow through a much longer 21-year tenure, under a given interest rate assumption — but the actual rate is revised every quarter by the government and will differ from any single illustrative figure. Use this projection to understand the shape of SSY's two-phase compounding, not as a guaranteed prediction of the exact maturity amount your daughter will eventually receive.

Opening the account early, depositing consistently during the required window, and revisiting the current interest rate periodically will do more for the eventual outcome than any single projection made at account opening.

Because the funds are ultimately intended for a specific milestone in your daughter's life, it is worth pairing the numeric projection with an honest conversation, as she grows older, about what the money is for and how it fits into the family's broader plans — the calculator answers the "how much," but the "what for" is a decision worth revisiting together well before the account matures.

This calculator models annual deposits for the first 15 years, compounded once per year on the running balance, with the balance continuing to compound without further deposits through year 21, using the interest rate you entered or the current default. This is general educational information, not investment or tax advice — verify current SSY rules, deposit limits, and the notified interest rate with your bank, post office, or the Ministry of Finance before making a financial decision.

As with the PPF model discussed above, actual SSY interest is computed monthly on the lowest qualifying balance rather than annually, so real passbook figures will differ slightly from this simplified projection.
