Sukanya Samriddhi Yojana Calculator – SSY Maturity Amount at 21 Years
Work out what a yearly SSY deposit becomes by maturity, at the current notified interest rate
Sukanya Samriddhi Yojana is a small savings scheme for a girl child, operated through post offices and authorised banks. A parent or guardian opens the account before she turns 10 and deposits for 15 years. The account then keeps earning interest without further deposits until it matures 21 years after opening. The interest rate is notified quarterly by the Ministry of Finance along with the other small savings rates, and deposits qualify for deduction under Section 80C.
Who Can Open an SSY Account?
The account is opened by a parent or legal guardian in the name of a girl child who has not yet turned 10. One account is allowed per girl, and ordinarily two accounts per family, with an exception where twins or triplets take the family beyond two girls. The girl herself can operate the account once she turns 18. The account can be transferred between post offices and banks, and it stays with the girl if the family moves.
Formula
Balance (next year) = (Balance + Yearly Deposit) × (1 + Rate ÷ 100)
Maturity = Balance at year 15 × (1 + Rate ÷ 100)⁶
Interest compounds annually. Deposits run for the first 15 years; years 16 to 21 earn interest with no further deposits. This calculator assumes one deposit at the start of each financial year, which is why published SSY figures differ from each other: a deposit made in March earns far less for that year than the same deposit made in April.
Worked Examples
Example 1: ₹1,50,000 a year, the scheme ceiling, opened when she is 1
Total deposited over 15 years = ₹22,50,000. Balance when deposits stop = ₹44,75,989. Maturity at 8.2% = ₹71,82,119, of which ₹49,32,119 is interest. She receives it at 22.
Example 2: ₹25,000 a year, opened when she is 5
Total deposited = ₹3,75,000. Maturity at 8.2% = ₹11,97,020, of which ₹8,22,020 is interest. She receives it at 26.

Assumes one deposit at the start of each financial year. Depositing later in the year earns less, because the scheme pays interest on the lowest balance between the 5th and the last day of each month. The interest rate is revised quarterly, so a long projection will drift.
Withdrawal Before Maturity
Two routes exist before the 21-year maturity. Once the girl turns 18 or has passed Class 10, up to half the balance at the end of the previous financial year can be withdrawn for her higher education, against proof of admission or fee demand. The account can also be closed early after she turns 18 if she marries, with closure permitted in the window from one month before to three months after the marriage date. Premature closure on other grounds, such as the death of the account holder or medical necessity, is allowed at the discretion of the operating office. A year with no deposit at all leaves the account in default until the minimum for that year is paid, along with the prescribed default fee.

Frequently Asked Questions
The latest confirmed SSY interest rate on this page is 8.2% per annum, notified for the quarter beginning October 2026. The Ministry of Finance reviews small savings rates every quarter, so check the latest notification before relying on a long projection.
Deposits are accepted for 15 years from the date the account is opened. The account matures 21 years after opening, so for the final six years the balance keeps earning interest without any further deposit from you.
The minimum is ₹250 in a financial year and the maximum is ₹1,50,000. Missing the ₹250 minimum puts the account in default until it is paid with the prescribed fee. Deposits above the ceiling are not accepted and earn no interest.
The account must be opened before the girl turns 10. One account is allowed per girl child and ordinarily two per family, with an exception where twins or triplets take the family beyond two girls.
Yes, in two cases. After she turns 18 or passes Class 10, up to 50% of the previous year's closing balance can be withdrawn for higher education against proof of admission. The account can also be closed on her marriage after 18, within one month before to three months after the marriage date.
Under current rules SSY has exempt-exempt-exempt treatment: deposits qualify for deduction under Section 80C, the interest accrues tax-free, and the maturity amount is not taxed. Tax rules change, so confirm the position for the year you withdraw.
Because the deposit date matters. The scheme pays interest on the lowest balance between the 5th and the last day of each month, so a deposit in April earns a full year of interest while one in March earns almost none. This calculator assumes a deposit at the start of each financial year, which is the best case. Calculators that assume a year-end deposit will show a lower figure for the same money.
