Deposits are made for the first 15 years from account opening, then the balance keeps compounding with no further deposits until the account matures 21 years after opening. Enter your annual contribution, the current SSY rate and the girl's current age to see the maturity value.
How much you deposit each financial year. SSY allows a minimum of ₹250 and a maximum of ₹1,50,000 per year.
Set by the government every quarter — currently 8.2%, one of the highest rates among government savings schemes.

How to use this sukanya samriddhi yojana calculator
- 1Annual contribution: how much you deposit each financial year for the first 15 years, between ₹250 and ₹1,50,000.
- 2SSY interest rate: the government revises this every quarter; SSY typically carries one of the highest rates among small savings schemes.
- 3Girl's current age at account opening: SSY accounts can only be opened before the girl turns 10, and this age determines how old she'll be at the 21-year maturity date.
Understanding your results
Maturity value is the account balance 21 years after opening — this reflects 15 years of deposits compounding, followed by 6 more years of compounding on the accumulated balance with no further contributions. Total contributed is your annual contribution multiplied by 15 (deposits stop after year 15). Total interest earned is the maturity value minus total contributed — the full tax-free gain.
The formula
Balance at 15 years = C × (((1 + r)¹⁵ − 1) / r) × (1 + r); Maturity at 21 years = Balance × (1 + r)⁶The first 15 years use the same annuity-due formula as PPF, since SSY deposits are also assumed made at the start of each year and compound annually. After year 15, no further deposits are made, so the balance at that point simply compounds for another 6 years at the same rate to reach the 21-year maturity date — that final stretch uses a plain lump-sum compounding formula since there are no new contributions to account for.
A worked example
₹50,000 deposited at the start of each year for 15 years, at the default 8.2% rate, builds a balance of ₹14,91,996 by year 15. Total contribution over those 15 years is ₹7,50,000. With no further deposits, that balance compounds for 6 more years to reach maturity at year 21: ₹23,94,040. Total interest earned over the full 21 years is ₹16,44,040.
Things to know
The SSY rate is set by the Ministry of Finance every quarter and this calculator applies one flat rate across the full 21-year period for simplicity — in reality the rate will almost certainly change multiple times over two decades, so treat this as an illustrative projection rather than a guarantee. The account matures 21 years from the date of opening, or on the girl's marriage after she turns 18, whichever is earlier. Always verify current rates and rules against official India Post or bank SSY scheme guidance.
Frequently asked questions
Do I have to keep depositing for all 21 years until maturity?+
No — deposits are required only for the first 15 years from account opening. After that, no further contributions are needed (or accepted beyond the annual minimum to keep the account active in some cases); the accumulated balance simply continues earning interest until the account matures at 21 years from opening.
What happens if the girl gets married before the account matures?+
The SSY account matures early and can be closed on marriage, provided she is at least 18 years old at the time — whichever comes first between the 21-year mark and marriage after 18. This calculator projects the full 21-year maturity value assuming no early closure.
Is SSY better than PPF for a daughter's education or marriage goal?+
SSY typically pays a higher interest rate than PPF and both share the same EEE (Exempt-Exempt-Exempt) tax status — contribution, interest and maturity are all tax-free. SSY is restricted to a girl child under 10 and has a fixed 21-year horizon, while PPF is open to anyone and more flexible on tenure, so the better choice depends on your goal's timeline and who the account is for.
