Introduction

Sukanya Samriddhi Yojana consistently offers the highest interest rate among government-backed small savings schemes, but the 21-year maturity window — 15 years of deposits followed by 6 years of pure compounding — confuses most first-time calculations. This calculator applies the exact compounding structure the scheme actually uses, so the number you see reflects the real payout, not a simplified guess.

Complete Guide: What Is SSY

Sukanya Samriddhi Yojana (SSY) is a government-backed savings scheme launched under the Beti Bachao, Beti Padhao initiative, designed to help parents and legal guardians build a tax-free corpus for a girl child's education and marriage. An account can be opened for any girl child below 10 years of age, by a resident parent or legal guardian, at any authorised bank or post office.

The interest rate is reviewed and notified quarterly by the Ministry of Finance. For Q1 of FY 2026-27 (April–June 2026), the rate stands at 8.2% per annum, compounded annually — unchanged for eight consecutive quarters since January 2024, and consistently higher than PPF and most bank fixed deposits.

Deposits can continue for 15 years from account opening, with a minimum of ₹250 and a maximum of ₹1.5 lakh per financial year. The account itself matures 21 years after opening — meaning that even though deposits stop after year 15, the accumulated balance keeps earning interest for a further 6 years before maturity. SSY carries EEE (Exempt-Exempt-Exempt) tax status: contributions qualify for Section 80C deduction up to ₹1.5 lakh, the annual interest is tax-free, and the maturity amount is entirely tax-free as well.

How to Use This Calculator

The Maturity Formula

SSY compounding happens in two distinct phases, and missing the second phase is the most common calculation error.

Common Mistakes to Avoid

• Forgetting the 6-year no-deposit compounding phase. Many rough calculations stop at year 15, understating the true maturity value.
• Assuming the rate stays fixed for 21 years. SSY rates are reviewed quarterly — this calculator uses the current rate as a constant projection, not a guarantee.
• Missing a year's minimum deposit. Skipping the ₹250 minimum in any year makes the account "irregular," attracting a small penalty until regularised.
• Opening more than two accounts without a twin/triplet exception. Families are generally limited to two SSY accounts.

Worked Example

Example — ₹5,000/Month. Depositing ₹60,000 a year (₹5,000/month) for 15 years, at a constant 8.2% rate, grows to approximately ₹26.5 lakh at 21-year maturity. Total invested over 15 years is ₹9 lakh, meaning the tax-free interest earned is roughly ₹17.5 lakh — nearly double the amount actually deposited.

Example — ₹1,000/Month. A smaller ₹12,000 a year (₹1,000/month) for 15 years grows to roughly ₹5.3 lakh at maturity, on total deposits of ₹1.8 lakh — still a meaningful tax-free corpus even at a modest contribution level.

Conclusion

The gap between what SSY investors put in and what they actually receive comes almost entirely from that extra 6-year compounding window after deposits stop — a detail simple calculators frequently skip. Running your actual planned deposit through this calculator, rather than relying on someone else's example, is the only way to know what your specific contribution level will realistically grow into by the time your daughter turns 21.
