About the Sukanya Samriddhi Yojana Calculator
This SSY calculator projects the maturity value of a Sukanya Samriddhi Yojana account — the Government of India small-savings scheme for a girl child. Enter the amount you plan to deposit each financial year, the current SSY interest rate and your daughter’s age when the account is opened. The calculator shows the maturity amount after 21 years, how much you deposited, the tax-free interest earned and the year the account matures.
It is for parents and legal guardians planning for a daughter’s higher education or marriage, and for anyone comparing SSY with PPF, fixed deposits or mutual fund SIPs. An account can be opened for a girl under 10 at a post office or authorised bank; deposits of ₹250 to ₹1.5 lakh are made each financial year for the first 15 years, and the account matures 21 years after opening.
The rate is set by the Ministry of Finance every quarter. It has been 8.2% a year since 1 January 2024, and the Department of Economic Affairs kept it unchanged for April–June and July–September 2026 (Q1 and Q2 of FY 2026-27), so 8.2% is the default here. The rate for October–December 2026 is announced around 30 September; change the rate if a new one is notified. The projection assumes the same deposit every year, made before the 5th of April so it earns interest for the full year, and the same rate throughout, compounded annually.
With the default inputs, the maturity value is ₹7,182,119.17. Change any value above to recalculate instantly.

Formula and method
SSY interest is calculated monthly on the lowest balance between the close of the 5th day and the end of the month, but credited and compounded once a year at the end of the financial year. If you deposit before 5 April, the whole deposit earns interest for the full year, so the yearly model above matches the scheme closely.
Deposits are made for the first 15 years. For the remaining 6 years no deposits are allowed, but the balance keeps earning the prevailing rate until maturity 21 years after opening. The calculator holds the rate constant; in practice it can change every quarter, so treat the result as an estimate and update the rate when a new one is notified.

Worked examples
Maximum ₹1.5 lakh a year at 8.2%
Depositing the maximum ₹1,50,000 every year for 15 years puts in ₹22.5 lakh. At 8.2% compounded yearly for 21 years the account matures at about ₹71.8 lakh, so roughly ₹49.3 lakh is tax-free interest. An account opened in 2026 for a 1-year-old matures in 2047, when she is 22.
₹50,000 a year for a 4-year-old
Deposits of ₹50,000 a year total ₹7.5 lakh over 15 years. At 8.2% the maturity value is about ₹23.9 lakh, more than three times the amount deposited, paid out when she turns 25.
₹1,000 a month (₹12,000 a year) if the rate falls to 7.6%
Saving ₹12,000 a year puts in ₹1.8 lakh. Even at a lower 7.6% rate, the account grows to about ₹5.27 lakh by maturity, with ₹3.47 lakh of interest.
