SSY Calculator: The Scheme Built for Your Daughter's Future

If you have a daughter under 10, there's a scheme out there that's so good the government is almost embarrassingly generous about it. It pays the highest interest rate of any small savings scheme in India. It's fully tax-exempt at every stage. And it's locked to a single, specific purpose: building a corpus for your daughter's education or wedding. The scheme is Sukanya Samriddhi Yojana, known simply as SSY, and if you're a parent who hasn't opened one yet, this guide is probably going to nudge you to finally fill out the form. We'll walk through how SSY actually works, how our SSY Calculator projects the maturity corpus, and the couple of rules that trip people up.

Full disclosure: this is probably the most emotionally loaded calculator on our entire site. Watching the corpus projection climb past ₹50 lakh while you're thinking of your five-year-old doing cartwheels in the next room is a peculiar kind of motivation.

So What Is SSY, Really?

Sukanya Samriddhi Yojana was launched in 2015 as part of the "Beti Bachao, Beti Padhao" initiative. It's a government-backed savings scheme available exclusively for girl children — and only girl children — under the age of 10. A parent or legal guardian opens the account at any post office or most authorised banks, and contributes anywhere between ₹250 and ₹1,50,000 per financial year into it. The rate is announced quarterly; as of 2026 it sits at around 8.2% compounded annually, which is the highest among all small savings schemes — higher than PPF, NSC, or SCSS.

Eligibility is strict and worth getting right: the account can be opened in the name of one girl child from birth up until she turns 10. A family can open a maximum of two SSY accounts total, one per daughter. There are a couple of exceptions — if your second childbirth results in twin/triplet girls, a third account is allowed. NRIs cannot open SSY accounts, and if the daughter becomes an NRI during the tenure, the parents must inform the post office.

The Timeline: 15 Years of Deposits, 21 Years to Maturity

This is the bit most people get wrong, so read this paragraph twice. You deposit into SSY only for the first 15 years from the date the account was opened. After 15 years, no more contributions are allowed — but the account keeps earning interest. The account fully matures 21 years from the date it was opened, at which point the entire corpus can be withdrawn (tax-free). Alternatively, the account matures earlier if the daughter gets married after age 18 — in which case you can close it then.

So if you open the account when your daughter is 3, you deposit until she's 18 (15 years of contributions), and then the account matures when she's 24 (21 years total). If you open it at age 8, deposits stop at age 23 and the account matures at age 29. The "deposit window" and "maturity" are two different things, and mixing them up is the single most common source of confusion on calculator forums.

How the SSY Calculator Actually Works

Under the hood, the calculator simulates year-by-year compounding. For each of the first 15 years, it adds your yearly deposit to the running balance, then applies the annual interest rate. For years 16 through 21, no deposit is added — the existing balance simply continues to compound at the same rate. The formula at each step is:

Balance_{year n} = (Balance_{year n-1} + Deposit_n) × (1 + r)

Where r is the annual interest rate (e.g., 0.082 for 8.2%), and Deposit_n is your yearly contribution for the first 15 years and zero after that. The calculator shows you the breakdown — total contributions vs total interest earned — so you can see exactly how much of the maturity corpus you built and how much the scheme gave you for free.

SSY is the closest thing to a "free lunch" the Indian government offers. EEE tax status, the highest rate in the small savings family, and it's ring-fenced for a purpose you already care about. The only reason not to max it out is if you don't have a daughter.

EEE Tax Status: The Best Tax Treatment Possible

SSY enjoys full EEE status, meaning it's tax-free at all three stages — the contribution (up to ₹1.5 lakh per year under Section 80C), the interest as it grows, and the maturity corpus when finally withdrawn. There is no other instrument in India that combines an 8.2% guaranteed rate and full EEE status. PPF comes close on tax, but at 7.1%. NSC has the rate but not the EEE. SSY wins on both dimensions — it's just restricted to girl children.

A Real Scenario: Meet Sneha's Father

Rajesh opens an SSY account for his daughter Sneha when she's 4 years old. He commits to depositing ₹1,50,000 per year (the maximum) for the full 15 years. He plans to use the corpus for her higher education and wedding expenses.

Plug ₹1,50,000 yearly, age 4, 8.2% into the SSY Calculator. Over 15 years, Rajesh invests a total of ₹22.5 lakh. The balance at year 15 (when deposits stop) is roughly ₹43.5 lakh. But the account keeps compounding for 6 more years at 8.2%. By year 21 (when Sneha is 25 and the account matures), the corpus stands at approximately ₹69.8 lakh — fully tax-free. Rajesh effectively got ₹47.3 lakh of interest on ₹22.5 lakh of contributions, with zero risk and zero tax.

For Rajesh in the 30% slab, the 80C deduction also saved him roughly ₹45,000 in tax per year for 15 years — another ₹6.75 lakh of implicit "return" on top of the headline corpus. That's before we even talk about the emotional value of handing your daughter a meaningful lump sum on her wedding day, with zero debt and zero financial stress.

Partial Withdrawal and Premature Closure

SSY is surprisingly rigid, by design. Once the daughter turns 18 or completes her 10th grade (whichever is earlier), you can withdraw up to 50% of the previous financial year's balance — for her higher education. This is the one escape hatch that matches the scheme's purpose. You'll need documentary proof of admission to a recognised institution.

Premature closure is permitted only in specific situations: death of the account holder (the daughter), a medical emergency (life-threatening illness), or if continuing the account causes "undue hardship" — though this last one is reviewed case by case and rarely approved. If the daughter gets married before turning 18, you cannot close the account early — SSY treats this as underage and rejects the closure. After 18 and after marriage, closure is allowed even before the 21-year maturity.

Common Mistakes People Make With SSY

• Not depositing the minimum ₹250 in a year. Your account becomes inactive ("defaulted") and must be revived by paying a ₹50 penalty per defaulted year plus the arrears. Two reminders to set on your calendar: one when you open the account, one a decade later.
• Opening multiple accounts for the same daughter. Only one SSY account per girl is allowed, period. If you accidentally open two, one will be flagged and won't earn interest.
• Assuming the rate is locked. The rate is announced quarterly and applies to the balance for that quarter. Historically SSY has paid between 7.6% and 9.2%, so budget for some variation — the calculator's "current rate" is a projection, not a promise.
• Depositing after March 31. SSY deposits follow the financial year (April–March). A deposit on April 1 counts for the new financial year, not the old one.
• Forgetting the 15-year deposit window. After year 15, you cannot contribute — even if your daughter is only 19. Don't plan on topping up during the "idle years."
• Not transferring the account when moving cities. SSY is transferable between post offices and authorised banks free of charge. File Form NS-1 to move it.

Key SSY Terms You'll Keep Seeing

• Account holder: The girl child in whose name the account is opened.
• Guardian: Parent or legal guardian who operates the account until the girl turns 18.
• Deposit window: The first 15 years from the date of opening — the only period during which contributions are allowed.
• Maturity: 21 years from the opening date, or when the girl marries after turning 18 — whichever is earlier.
• 80C eligibility: Deposits up to ₹1.5 lakh per year qualify under Section 80C.
• EEE: Exempt-Exempt-Exempt — the best possible tax treatment.
• Partial withdrawal: Up to 50% of the previous year's balance, allowed after the girl turns 18 or completes class 10.

How to Use Our SSY Calculator in 30 Seconds

1. Enter your yearly deposit. Anywhere from ₹250 to ₹1,50,000. For meaningful corpus building, aim for at least ₹50,000.
2. Enter your daughter's current age. Must be between 0 and 10 for her to be eligible.
3. Keep the interest rate at 8.2% — the current rate. Drop to 7.8% for a conservative projection.
4. Read the maturity corpus and the year-by-year breakdown. The corpus is what's available when she turns the age the calculator shows.
5. Try different deposit levels — running ₹50,000/year vs ₹1,50,000/year shows you the full range of what's possible.

Frequently Asked Questions

Who can open an SSY account?

A parent or legal guardian of a girl child below 10 years of age. The account is opened in the daughter's name, and the guardian operates it until she turns 18. Only Indian residents are eligible — NRIs cannot open or inherit SSY accounts, and if the daughter becomes NRI during the tenure, the account must be closed.

Can I have two SSY accounts?

You can have one SSY account per daughter, up to a maximum of two accounts per family. Exception: if your second childbirth results in twin or triplet girls, a third account is allowed with proper medical certification. The ₹1.5 lakh annual deposit cap applies across all SSY accounts in the family combined.

Is SSY interest really tax-free?

Yes, entirely. SSY has full EEE status under the Income Tax Act. The deposit qualifies for 80C (old regime only), the interest accrued each year is not taxable, and the maturity corpus is fully tax-free on withdrawal. This is one of only three or four instruments in India with true EEE status.

SSY vs PPF — which one should I choose?

If you have a daughter under 10, do both. SSY has a higher rate (8.2% vs 7.1%) and is ring-fenced for her, while PPF is more flexible and can be extended indefinitely. Max out SSY first up to ₹1.5 lakh, and if you have more room in 80C, put the rest in PPF. The combined ₹1.5 lakh cap applies across all 80C investments, so pick one "primary" if that's your total budget.

What happens if my daughter becomes an NRI?

You must inform the post office or bank within a month of her status change. The account stops earning interest from the date of NRI status and must be closed at that time. Any interest earned from that date onwards is reversed. This is a rule that catches many families off guard when daughters pursue higher studies abroad.

Can I withdraw the full corpus before 21 years?

Only under specific conditions. Full withdrawal is allowed when the daughter turns 18 and has completed her 10th standard — you can withdraw up to 50% for education. Full closure is permitted on her marriage after age 18, on her death, on a medical emergency, or on certified "undue hardship." Otherwise, the account runs its full 21-year course.

What happens if I can't deposit for a few years?

As long as you deposit the minimum ₹250 each year, the account stays active. Miss that, and it becomes "defaulted" — it still earns interest on existing balance, but you can't make fresh deposits until you revive it. Revival costs ₹50 per defaulted year plus all arrears. Set a standing instruction to deposit ₹250 on April 2 every year, just as an insurance policy against forgetfulness.

The One Thing to Take Away

If you have a daughter under 10, open an SSY account this month. Not because of the emotional pitch — though that's real — but because the math is just better than anything else available to you. Highest guaranteed rate. Full EEE tax status. Purpose-built. Government-backed. Run your numbers on the SSY Calculator, commit to whatever yearly amount you can sustain (even ₹12,000 is fine), and then set it up as an annual standing order and forget about it for 15 years.

Future you — and definitely future her — will be very, very grateful.
