Sukanya Samriddhi takes deposits for 15 years and matures 21 years after opening. ₹1.5 lakh a year, paid by 5 April, at 8.2% grows to about ₹71.8 lakh on ₹22.5 lakh deposited, all tax-free; paying monthly instead gives about ₹69.3 lakh.

Rates as of 1 October to 31 December 2026 (Q3 FY 2026-27), notified 30 September 2026. Sukanya Samriddhi Account: 8.2% a year. The government resets small savings rates every quarter; a deposit keeps the rate it was opened at, except PPF and SSY, which follow each quarter’s rate.

Deposits run for 15 years and interest keeps compounding until year 21. Interest is credited yearly on the lowest balance between the 5th and the month end, so money in by 5 April earns the whole year. The rate is reset every quarter; this assumes today’s rate throughout.

How the 21 years work

For a yearly deposit D paid by 5 April, each year's balance is (last balance + D) × (1 + r) for the first 15 years and last balance × (1 + r) for the remaining six. At 8.2% with the ₹1.5 lakh maximum, ₹22.5 lakh deposited grows to about ₹71.8 lakh. Closed form, as a check: 1.5 lakh × (1.0827 + 1.0828 + … + 1.08221).

Why 5 April matters

Interest for each month is paid on the lowest balance between the 5th and the end of the month. Money that arrives by 5 April earns all twelve months; paying ₹12,500 a month instead means each instalment earns only from its own month. Over 21 years that difference is about ₹2.5 lakh (₹71.8 lakh against ₹69.3 lakh). Switch "How you deposit" above to see it on your figures.

Who can open one

A parent or legal guardian, for a girl under 10, at a post office or an authorised bank; one account per girl and up to two per family (three for twins or triplets in the second birth). Compare with PPF, which any adult can open and which has a lower rate but no age limit, or the five-year NSC.

Frequently asked questions

What is the Sukanya Samriddhi interest rate now?

8.2% a year, compounded yearly, for 1 October to 31 December 2026 (Q3 FY 2026-27). Unlike a fixed deposit, an SSY account follows each quarter’s notified rate for its whole life, so the final figure will differ if the rate changes.

For how many years do I deposit, and when does it mature?

You deposit for 15 years from opening; the account matures 21 years from opening. In years 16 to 21 no deposits are made, but interest keeps compounding, which is why the last six years add so much.

How much can I deposit?

At least ₹250 and at most ₹1.5 lakh in a financial year, in as many instalments as you like. Missing the ₹250 minimum makes the account irregular; it can be regularised with a ₹50 penalty for each year missed plus the missed minimums.

Is Sukanya Samriddhi tax-free?

Under the old tax regime, deposits qualify for the ₹1.5 lakh deduction, and the interest and maturity amount are exempt. Under the new regime there is no deduction for the deposit, but the interest and maturity stay tax-free.

Can money be withdrawn before 21 years?

Up to 50% of the balance at the end of the previous financial year can be withdrawn once she turns 18 or passes Class 10, for her education. The account can be closed early for her marriage after 18, and in limited cases such as the death of the girl or severe medical need.
