Invest ₹1.5 lakh per year for 15 years (₹22.5 lakh total) and receive ₹71.82 lakh after 21 years — completely tax-free. That's ₹49.32 lakh in interest earned, more than double your total investment. The Sukanya Samriddhi Yojana (SSY), launched under the Beti Bachao Beti Padhao initiative, offers 8.2% compounded annually — the highest rate among all EEE (Exempt-Exempt-Exempt) government schemes, beating both PPF (7.1%) and bank fixed deposits (6.5-7.5%) while being fully backed by sovereign guarantee.
This guide covers everything: eligibility rules, deposit structure, maturity calculations at every investment level, the education withdrawal option, tax benefits, SSY vs PPF comparison, interest rate history, and — what no competitor covers — the real return after inflation. Use our SSY Calculator to model your daughter's specific scenario.
Interest rate: 8.2% p.a. (Q4 FY 2025-26) | Deposit period: 15 years | Maturity: 21 years | Min deposit: ₹250/year | Max deposit: ₹1.5 lakh/year | Tax: EEE (fully tax-free) | Eligibility: Girl child below 10
SSY Maturity Amount at Various Deposit Levels
All figures computed at 8.2% annual compounding, 15 years of deposits, 21-year maturity (verified):
| Annual Deposit | Monthly Equivalent | Total Invested (15yr) | Maturity (21yr) | Interest Earned | Interest as % of Investment |
|---|---|---|---|---|---|
| ₹250 | ~₹21 | ₹3,750 | ₹11,976 | ₹8,226 | 219% |
| ₹10,000 | ₹833 | ₹1.50L | ₹4.79L | ₹3.29L | 219% |
| ₹50,000 | ₹4,167 | ₹7.50L | ₹23.94L | ₹16.44L | 219% |
| ₹1,00,000 | ₹8,333 | ₹15.00L | ₹47.88L | ₹32.88L | 219% |
| ₹1,50,000 | ₹12,500 | ₹22.50L | ₹71.82L | ₹49.32L | 219% |
At every deposit level, you earn 219% on your investment — the power of 8.2% compounding over 21 years. Even a modest ₹10,000/year builds ₹4.79 lakh tax-free for your daughter. The Rule of 72 tells us: at 8.2%, money doubles every 8.8 years. With 21 years of compounding, the multiplication effect is dramatic.
Year-Wise Corpus Growth (₹1.5 Lakh/Year)
| Year | Total Deposited | Corpus | Interest Earned | Milestone |
|---|---|---|---|---|
| 1 | ₹1.5L | ₹1.62L | ₹0.12L | Account opened |
| 5 | ₹7.5L | ₹9.56L | ₹2.06L | Interest > 1 year's deposit |
| 10 | ₹15.0L | ₹23.74L | ₹8.74L | Interest > half of total deposits |
| 15 | ₹22.5L | ₹44.76L | ₹22.26L | Last deposit year — interest ≈ deposits! |
| 18 | ₹22.5L | ₹56.70L | ₹34.20L | 50% withdrawal for education available |
| 21 | ₹22.5L | ₹71.82L | ₹49.32L | Maturity — fully tax-free |
The corpus nearly doubles after deposits stop (Year 15: ₹44.76L → Year 21: ₹71.82L) — those final 6 years of pure compounding with zero deposits add ₹27 lakh. This is why opening the account early and maximizing deposits for 15 years is so impactful. The compound interest accelerates exponentially in later years.
Education Withdrawal: 50% at Age 18
Once the girl child turns 18 or passes 10th standard, up to 50% of the previous year's closing balance can be withdrawn for higher education expenses (admission fees, hostel charges). This is a critical feature for funding college without breaking the account.
| Account Opened At | Corpus at Age 18 | 50% Withdrawal Available | Remaining Grows to Maturity |
|---|---|---|---|
| Birth (age 0) | ₹56.70L (Year 18) | ₹28.35L | Remaining ₹28.35L grows further |
| Age 5 | ₹35.35L (Year 13) | ₹17.67L | Remaining grows 8 more years |
| Age 9 (last eligible) | ₹14.70L (Year 9) | ₹7.35L | Remaining grows 12 more years |
Opening at birth gives maximum education fund — ₹28.35 lakh available at 18 for college fees, with the remaining half continuing to compound until maturity at 21. This dual benefit — education funding AND continued growth — makes SSY uniquely suited for girl child financial planning.
SSY vs PPF vs FD: The Complete Comparison
| Parameter | SSY | PPF | FD (30% bracket) |
|---|---|---|---|
| Interest rate | 8.2% | 7.1% | 6.5-7.5% |
| Tax status | EEE | EEE | Interest taxed at slab |
| Effective post-tax rate | 8.2% | 7.1% | 4.55-5.25% |
| Real return (6% CPI) | +2.08% | +1.04% | -1.04% |
| ₹1.5L/yr × 21yr maturity | ₹71.82L | ₹61.40L | ₹44.90L |
| SSY advantage | — | +₹10.43L more | +₹26.92L more |
| Lock-in | 21 years | 15 years (extendable) | Flexible tenure |
| Eligibility | Girl child < 10 only | Any Indian citizen | Anyone |
| Government backing | Sovereign guarantee | Sovereign guarantee | DICGC ₹5L per bank |
| Annual limit | ₹1.5 lakh | ₹1.5 lakh | No limit |
SSY outperforms PPF by ₹10.43 lakh and FD by ₹26.92 lakh over the same 21-year horizon with the same annual investment. The 1.1% rate advantage over PPF compounds into a massive gap. For boys, PPF is the next best option — see our NPS vs PPF vs EPF guide. For overall retirement corpus planning beyond SSY, see our retirement corpus guide.

₹71.82 lakh sounds impressive — but what will it buy in 21 years? At 6% average CPI inflation, the purchasing power erosion is significant:
| Inflation Rate | SSY Maturity (₹71.82L) | Real Value (Today's ₹) | Education Cost Today | Education Cost in 21yr |
|---|---|---|---|---|
| 5% | ₹71.82L | ₹25.78L | ₹25L (MBBS) | ₹69.7L |
| 6% | ₹71.82L | ₹21.13L | ₹25L (MBBS) | ₹85.0L |
| 7% | ₹71.82L | ₹17.35L | ₹25L (MBBS) | ₹1.03 Cr |
At 6% inflation, your ₹71.82 lakh has the purchasing power of only ₹21.13 lakh in today's money. Meanwhile, an MBBS degree costing ₹25 lakh today will cost ₹85 lakh in 21 years. SSY alone may not cover premium education costs — which is why smart parents pair SSY with equity SIP investments for higher growth. SSY's real return of +2.08% (8.2% - 6% CPI) is positive but modest. A Step-Up SIP in equity mutual funds at 12% CAGR delivers +5.66% real return — supplementing SSY with even ₹5,000/month equity SIP creates a much more robust education fund. Use our SIP Calculator, Step-Up SIP Calculator, Education Cost Calculator, and Inflation Calculator to plan the combined strategy. For tax-saving options alongside SSY, explore Section 80C instruments including ELSS, EPF, and NPS (with its extra ₹50K deduction under 80CCD(1B)).
