Sukanya Samriddhi Yojana (SSY) 2026: Interest, Rules & Rs 1,000/Month Returns

For a parent of a young daughter in India, few government schemes carry the pull of the Sukanya Samriddhi Yojana. It promises one of the highest interest rates of any small-savings product, a fully tax-free maturity, and the discipline of a long-term lock-in tied to a child's future. The most common question is also the most practical: what does a modest deposit, say Rs 1,000 a month, actually grow into.

The Sukanya Samriddhi Yojana (SSY) is a government-backed savings scheme for a girl child, offering 8.2% interest a year in 2026 and Exempt-Exempt-Exempt tax treatment. It is operated through post offices and authorised banks, and it sits among the safest and highest-yielding options a family can use to build a corpus for a daughter's education or marriage.

This guide explains the SSY interest rate, the deposit and maturity rules, and exactly what a Rs 1,000 or larger monthly contribution returns over the life of the account, with figures sourced to the scheme's current terms.

SSY at a glance in 2026

The Sukanya Samriddhi Yojana pays 8.2% per year for the April to June quarter of FY2026-27, compounded annually. The account can be opened for a girl child below the age of 10, with a minimum deposit of Rs 250 and a maximum of Rs 1.5 lakh in a financial year.

Deposits run for 15 years from the date of opening, but the account matures only after 21 years, with interest continuing to accrue in the intervening years. The scheme is offered at any post office and most banks, and the full family of small-savings options is compared in the Post Office Savings Schemes guide.

The SSY interest rate and how it is set

The SSY interest rate is 8.2% for the first quarter of FY2026-27, the highest among comparable small-savings schemes. The rate is set by the Ministry of Finance and reviewed every quarter, so it can change through the life of the account.

Because the rate is revised quarterly, the eventual maturity value depends on the path of rates over 21 years rather than a single fixed number. Historically SSY has been kept at or near the top of the small-savings table, reflecting its social objective of supporting the girl child.

"The interest rate on the Sukanya Samriddhi Account for the quarter is 8.2% per annum, compounded annually." (National Savings Institute, 2026.)

How interest is calculated

SSY interest is calculated on the lowest balance in the account between the close of the fifth day and the end of each month. The interest is then credited once a year, at the end of the financial year, and compounds annually thereafter.

This calculation method rewards depositing early in the month and early in the financial year, since money sitting in the account for the full period earns the most. A deposit made before the 5th counts toward that month's interest, while one made later misses interest for that month.

Over a 21-year horizon, the difference between consistently depositing at the start of the year and at the end can add up to a meaningful sum, because each early rupee earns an extra slice of compound interest every subsequent year. Disciplined timing, not just disciplined saving, lifts the final corpus.

What does Rs 1,000 a month return?

A deposit of Rs 1,000 a month, or Rs 12,000 a year, sustained for the full 15-year deposit period, grows to roughly Rs 5.5 lakh by maturity at the current 8.2% rate. The exact figure depends on the rate over the full term, but the order of magnitude is a more-than-doubling of the total amount deposited.

The reason the return is so strong is the six additional years of compounding after deposits stop: contributions run for 15 years, but interest keeps accruing until year 21. Families can model their own numbers with the Sukanya Samriddhi Yojana calculator.

These figures assume the rate holds at 8.2% throughout, which is unlikely to be exact, but they show the scale of the corpus a steady habit can build.

Deposit rules and limits

The minimum deposit is Rs 250 in a financial year and the maximum is Rs 1.5 lakh, with deposits accepted in multiples convenient to the saver. There is no fixed monthly schedule: a family can deposit in instalments or as a lump sum within the annual cap.

If the minimum Rs 250 is not deposited in a year, the account is treated as in default, though it can be revived by paying Rs 250 plus a Rs 50 penalty for each defaulted year. Keeping the account active is therefore inexpensive even in a difficult year.

Eligibility and account rules

An SSY account can be opened only for a girl child who is below 10 years of age, by a parent or legal guardian. A family can open a maximum of two accounts, one for each of two girls, with an exception allowing a third in the case of twins or triplets.

The account is operated by the guardian until the girl turns 18, after which she can operate it herself. The girl child is the beneficiary and the account is held in her name throughout.

Maturity, withdrawal and closure

The account matures 21 years from the date of opening, at which point the full balance with interest is paid to the girl. A partial withdrawal of up to 50% of the previous year's balance is allowed once the girl turns 18, intended to fund higher education.

Premature closure is permitted in specific situations, such as the marriage of the girl after she turns 18, or in the event of her death or other compassionate grounds. Outside these cases the lock-in is the price of the high, tax-free return.

How to open an SSY account

An SSY account is opened in person at any post office or authorised bank branch, not online, by submitting the account-opening form with the required documents. The parent or guardian completes Form-1 and makes the first deposit to activate the account.

The core documents are the girl child's birth certificate, the identity and address proof of the guardian, and a photograph. Where a birth certificate is unavailable, a school or domicile certificate establishing the date of birth is accepted.

Once the account is open, standing instructions for automatic deposits can usually be set up online through net banking, even though the initial opening must be done at the counter. The detailed document checklist and step-by-step process are covered in the companion SSY documents guide.

Why the post-deposit years matter so much

The single biggest driver of the SSY maturity figure is the six-year gap between the end of deposits and maturity. Deposits stop after 15 years, but the accumulated balance keeps earning 8.2% compound interest until the 21st year.

In those final years, interest is being earned on a large balance with no fresh deposits required, so the corpus grows fastest precisely when the saver is contributing nothing. This is why SSY rewards opening the account as early in the girl's life as possible.

A delay of even a few years in opening the account shortens the high-compounding tail, since maturity is fixed at 21 years from opening regardless of the girl's age. Starting at birth captures the full benefit of the structure.

Transfer and NRI rules

An SSY account can be transferred freely between post offices and banks anywhere in India, at no cost if supported by proof of the account holder's address change. This portability means a family that relocates does not have to disturb the account.

The scheme is meant for resident girl children, and if the girl becomes a non-resident or changes citizenship after the account is opened, the account must be closed, with the change in status notified. This residency condition is important for families with overseas plans.

Tax benefits: the EEE advantage

The Sukanya Samriddhi Yojana carries Exempt-Exempt-Exempt status, one of the most favourable tax treatments available. Deposits qualify for deduction under Section 80C up to Rs 1.5 lakh, the annual interest is exempt, and the maturity proceeds are fully tax-free under Section 10.

This EEE treatment is shared by only a handful of instruments, notably the Public Provident Fund, making SSY effectively a girl-child-specific cousin of PPF. The two are compared alongside other options in the Post Office PPF guide.

"Deposits made in the Sukanya Samriddhi Account qualify for deduction under Section 80C, and the interest and maturity amount are exempt from income tax." (National Savings Institute, 2026.)

SSY versus other savings options

SSY's 8.2% rate sits above the PPF and most fixed deposits in 2026, and its EEE status beats taxable options like bank FDs and the National Savings Certificate. The trade-off is the long lock-in and the eligibility restriction to a girl child under 10.

For families specifically saving for a daughter, SSY is usually the single best small-savings choice on a pure return-and-tax basis. Where the goal is broader, the scheme is often paired with PPF or, for women savers, the schemes set out in the best post office schemes for women guide.

One practical limitation is liquidity: SSY locks money away far longer than a fixed deposit or even PPF's partial-withdrawal window, so it should fund a long-dated goal rather than an emergency reserve. A family typically keeps a separate, more liquid buffer alongside the SSY account rather than routing all savings into it.

It is also worth remembering that the Rs 1.5 lakh annual cap is shared with the Section 80C limit, so a saver maximising SSY has less 80C room left for other instruments. Planning the year's 80C allocation across SSY, PPF and any insurance premiums avoids crowding out one goal for another.

Looking ahead

The Sukanya Samriddhi Yojana remains the flagship girl-child savings scheme in 2026, anchored by a market-leading 8.2% rate and unmatched EEE tax treatment. As long as the government keeps the rate at the top of the small-savings table, a disciplined monthly habit started early will compound into a substantial, tax-free corpus.

For a parent weighing where to put a fixed monthly amount for a daughter, the maths is compelling: even Rs 1,000 a month grows past Rs 5 lakh, and the full Rs 1.5 lakh annual cap approaches Rs 70 lakh. The scheme rewards starting young and staying consistent.

The practical advice that follows from the structure is simple: open the account as early as possible, deposit before the 5th of the month, and treat the annual minimum as non-negotiable so the account never lapses. Done that way, the Sukanya Samriddhi Yojana turns a small, steady habit into one of the most reliable tax-free corpuses available to an Indian family.

Key takeaways

• SSY pays 8.2% a year in 2026, compounded annually, among the highest of all small-savings schemes.

• It can be opened for a girl child under 10, with Rs 250 to Rs 1.5 lakh deposited per year for 15 years; the account matures at 21 years.

• Rs 1,000 a month grows to roughly Rs 5.5 lakh, and the Rs 1.5 lakh annual maximum to about Rs 69-70 lakh, at the current rate.

• The scheme is EEE: deposits qualify under Section 80C and both interest and maturity are tax-free.

• The rate is reviewed quarterly, so actual maturity depends on the rate path over the full 21-year term; open early and deposit before the 5th of the month to maximise compounding.
