What is a SSY?
A Sukanya Samriddhi Yojana Calculator projects the maturity amount of an SSY account based on the annual deposit, the current interest rate of 8.2% p.a., and the daughter's age at the time of account opening. It shows the year-by-year corpus growth, the total deposits made over 15 years, the total interest earned tax-free over 21 years, and key milestone dates — last deposit year, the 50% withdrawal eligibility date, and the final maturity year.
Sukanya Samriddhi Yojana is one of the most underutilised financial instruments in India despite being arguably the most compelling forced-savings scheme for families with daughters. Launched in 2015 under the Beti Bachao Beti Padhao programme, SSY is backed by the Government of India, offers a guaranteed 8.2% annual return (higher than PPF), qualifies for full EEE tax treatment, and creates a dedicated corpus that cannot be prematurely accessed except for education or marriage. The account opened today for a 3-year-old daughter will mature in 2047 with full tax-free proceeds.
The mathematics of SSY are compelling. A family depositing ₹1,50,000 per year (the maximum) for 15 years invests ₹22.5 lakh in total. At 8.2% compounded annually, the 21-year maturity amount is approximately ₹71 lakh — with ₹48.5 lakh coming entirely from interest, all of it tax-free. At a 30% tax bracket, the equivalent pre-tax return from a taxable instrument would need to be approximately 11.7% per annum to produce the same post-tax result — a level that only equity markets can aspire to, without the guarantee.
The PPF Calculator is a natural companion for families already investing in SSY — together they provide two government-backed, EEE-status vehicles that build the low-risk foundation of a long-term financial plan. For the equity growth layer, the SIP Calculator can model the complementary equity allocation.
How to use this SSY calculator
- Enter Annual Deposit — the amount you plan to deposit each financial year, from ₹250 to ₹1,50,000. The maximum is ₹1.5 lakh per year; deposits can be made monthly, quarterly, or as a lump sum.
- Enter Daughter's Current Age — from 0 (newborn) to 10 (maximum age at account opening). The maturity age is always 21 years from opening, so her age at maturity = current age + 21.
- Set Interest Rate — the default is 8.2% (current Q1 FY 2026-27 rate). Adjust downward to model a conservative scenario.
- Read the maturity amount — the result card shows the corpus at maturity, the total deposited, and the total interest earned.
- Review the year-by-year table — expand to see all 21 years, with the last deposit year (year 15), education withdrawal eligibility (year 18), and maturity (year 21) highlighted.
Formula & Methodology
Deposit phase (Years 1–15): At the beginning of each year, the annual deposit is added to the corpus. At year end, interest is credited on the full balance. Interest phase (Years 16–21): No new deposits. Interest continues to compound annually on the accumulated balance. Formula per year: - If year ≤ 15: Corpus = (Corpus + Annual Deposit) × (1 + r) - If year > 15: Corpus = Corpus × (1 + r) Where r = interest rate ÷ 100. Total Interest = Maturity Amount − Total Deposits Worked example: A family opens an SSY account for their 2-year-old daughter in 2026, depositing ₹75,000 every year at 8.2% p.a. - Total deposits (15 years × ₹75,000) = ₹11,25,000 - Maturity year: 2026 + 21 = 2047 (daughter turns 23) - Last deposit year: 2026 + 15 = 2041 (daughter turns 17) - 50% withdrawal eligible: 2026 + 18 = 2044 (daughter turns 20) Corpus at maturity: - After Year 15 (deposits complete): approx. ₹22.8 lakh - After Years 16–21 (interest only, no deposits): corpus grows from ₹22.8 lakh to approx. ₹36.0 lakh - Total Interest Earned: ₹36.0 lakh − ₹11.25 lakh = ₹24.75 lakh (all tax-free) In 2044, when the daughter turns 20, up to 50% of the previous year's balance (approx. ₹16–17 lakh) can be withdrawn for college fees — without closing the account or affecting the compounding on the remaining balance through 2047.
