SSY Calculator India - Sukanya Samriddhi Yojana Maturity Amount

How the SSY Calculator Works - and What the Numbers Mean

Sukanya Samriddhi Yojana is India's most powerful government-backed girl child savings scheme, launched in 2015 under the Beti Bachao Beti Padhao initiative. It works on a simple but powerful structure: you deposit money for 15 years, and the account matures at 21 years from opening, building a guaranteed, tax-free corpus for your daughter's higher education or marriage. The key insight most parents miss is the interest-only compounding phase - for 6 years after you stop depositing (years 16 to 21), the accumulated corpus continues to earn 8.2% compounded annually. This silent compounding phase often adds more interest than the first few years of deposits, making SSY one of the best long-term wealth creation instruments in India for girl children. To understand how compounding stacks up against inflation over a 21-year horizon, use our Real Return Calculator.

The SSY interest calculation follows this logic: each year, the balance at the start of that year earns 8.2% annual compounding. Deposits made during the year are also eligible for that year's interest. Our calculator applies this correctly - the same method used by India Post and all authorised bank branches offering SSY accounts. This is distinct from monthly compounding schemes - SSY compounds annually, and understanding this matters for accurate projections.

SSY vs PPF vs FD - Which Gives the Best Return?

Bottom line: SSY is the highest guaranteed return EEE instrument in India. For a parent saving specifically for a daughter's higher education and marriage, SSY beats PPF on rate (8.2% vs 7.1%) with the same complete tax exemption. The only trade-off is the longer 21-year lock-in - which is actually an advantage if you open it early, as it matures exactly when the daughter is ready for college or marriage.

How Much Will ₹50,000/Year Grow in SSY? - Daughter Education & Marriage Fund Reference

At maximum deposit of ₹1.5 lakh/year, SSY can build a corpus close to ₹85 lakhs - completely tax-free. Compare this to a taxable FD at 7% which, after 30% tax, gives an effective return of ~4.9%, generating a much smaller corpus with full tax liability on the interest.

One critical reality most SSY guides ignore: education costs in India inflate at 10-12% annually, not the general CPI rate of 6%. This means SSY's guaranteed 8.2% return, while excellent for a risk-free instrument, may not fully cover the rising cost of a professional degree by the time your daughter turns 18-21. A ₹85 lakh SSY maturity corpus in 21 years has the purchasing power of roughly ₹25-27 lakh in today's money at 6% inflation. The optimal strategy most financial planners recommend is the SSY + SIP combo: use SSY as the guaranteed, tax-free floor for your daughter's financial security, and run a parallel step-up SIP in an equity mutual fund to bridge the education inflation gap. For instance, ₹50,000/year into SSY plus ₹3,000/month into a flexi-cap SIP gives you guaranteed corpus plus potential equity growth over the same 15-21 year horizon. To project exactly how much your daughter's education and career will cost by the time she needs the money, run the numbers through our Child Education Planning Calculator. For a comprehensive guide on how to build this two-layer strategy, see our child education planning guide for India, which covers SSY, SIP, and ELSS in combination.

SSY Rules, Partial Withdrawal and Premature Closure - All Scenarios

SSY is a small savings scheme governed by the Sukanya Samriddhi Account Rules, 2016, and regulated by the Ministry of Finance. Understanding the rules prevents costly mistakes - especially around the partial withdrawal at age 18, which is a unique feature no other small savings scheme offers, and which makes SSY a powerful two-stage tool: first building a higher education fund at 18, then delivering the full marriage and financial security corpus at 21.

Partial Withdrawal at Age 18 - For Education

Once the girl child turns 18 (or passes Class X, whichever is later), you can withdraw up to 50% of the balance at the end of the previous financial year. This is specifically for higher education expenses - college admission fees, hostel charges, etc. You need to submit proof of admission or fee demand letter. This withdrawal does not affect the remaining balance, which continues to earn 8.2% until maturity at 21.

Account Opening Requirements

• Girl child must be below 10 years of age at time of opening
• Documents: Girl's birth certificate, guardian's Aadhaar, guardian's PAN, address proof
• Minimum initial deposit: ₹250
• Maximum 2 accounts per family (one per girl child); exception for twins/triplets
• Available at all post offices and authorised bank branches across India
• SSY pairs well with NPS and EPF - together they cover your daughter's future, your retirement, and your employer's provident fund in one tax-efficient stack

Two things parents often miss: the timing of opening and the account portability rule. Opening SSY at birth (age 0) versus waiting until age 5 makes a significant difference: a ₹50,000/year deposit started at birth gives a 21-year compound window, while starting at age 5 cuts the effective compounding period and the total number of deposit years. The Cost of Delay Calculator can quantify exactly how many lakhs each year of delay costs in a 21-year scheme. On portability: SSY accounts are fully transferable across India, between any post office and any authorised bank branch, with no penalty. If you relocate cities, simply submit a transfer request at the new branch with your passbook and KYC documents. Finally, from a family tax planning perspective, the optimal government scheme stack is: SSY ₹1.5L/year for the daughter's corpus + PPF ₹1.5L/year for your own long-term corpus + NPS for the additional ₹50,000 Section 80CCD(1B) deduction. A detailed breakdown of how NPS vs EPF vs PPF compare for retirement helps parents see how to allocate the remaining 80C budget after SSY.

Frequently Asked Questions

What Is SSY Corpus Actually Worth When Your Daughter Needs It?

The ₹85 lakh maximum maturity figure is in nominal rupees 21 years from now, not today's money. At India's average 6% CPI inflation, ₹85 lakh in 21 years has the purchasing power of approximately ₹25-27 lakh in today's rupees. This is not a reason to avoid SSY. It's a reason to understand what it covers and plan accordingly. Use our Purchasing Power Calculator to see the real value of any amount in future years. For a deeper analysis of how the rupee's purchasing power erodes over long horizons in India, see the purchasing power of the rupee guide, which uses official MOSPI CPI data.

On the marriage cost side: wedding expenses in India have been inflating at 8-10% annually. A wedding that costs ₹15 lakh today will cost ₹65-85 lakh in 20 years at 8% inflation. This means SSY at maximum deposit is designed to roughly cover a mid-range wedding corpus by maturity, but education costs (which inflate at 10-12%) may need supplementation from equity SIP. The Marriage Cost Calculator helps you project the exact target corpus needed for your daughter's wedding, factoring in ceremony, jewellery, and venue inflation rates. For the girl child's education specifically, our Child Education Planning Calculator models degree costs (engineering, medicine, MBA) at their specific inflation rates, helping you determine whether SSY alone is sufficient or if a parallel SIP is needed.
