Sukanya Samriddhi Yojana (SSY) Calculator
Estimate the maturity value of a Sukanya Samriddhi account: 15 years of deposits compounding to maturity 21 years after opening.
How it works
Deposits compound annually for 15 years, then the balance keeps compounding with no new deposits until 21 years after opening: balance = (balance + deposit) × (1 + rate) for years 1–15, then × (1 + rate) for years 16–21
Sukanya Samriddhi Yojana is a small-savings scheme for a girl child that accepts deposits for 15 years but only matures 21 years after the account is opened. During the deposit window each yearly contribution compounds at the government rate, and for the remaining years the balance keeps compounding on its own with no fresh money added. Both the interest and the maturity amount are tax-free, which lifts the effective return above the headline rate.
Worked example
Depositing the ₹1.5 lakh yearly maximum for 15 years at 8.2%, then letting it compound to year 21, grows to about ₹71.8 lakh. That comes from ₹22.5 lakh of deposits and roughly ₹49.3 lakh of tax-free interest. Opened for a 5-year-old, the account matures when she is 26.
Frequently asked questions
How long do I deposit into an SSY account?
You deposit for 15 years from the date the account is opened, subject to a ₹1.5 lakh annual cap and a ₹250 minimum. The account then continues to earn interest until it matures 21 years after opening, even though no new deposits are allowed after year 15.
When can the money be withdrawn?
The account matures 21 years after it is opened, or on the girl marriage after she turns 18. A partial withdrawal of up to 50% of the prior-year balance is allowed once she reaches 18 for higher education.
Is the SSY interest rate fixed for the whole term?
No. Like other small-savings schemes the rate is reviewed by the government every quarter, so it can change over the 21-year life of the account. The 8.2% default is the rate at the time of writing.
