Rate last checked on 7 October 2026. The 8.2% rate applies to the October to December 2026 quarter: the Department of Economic Affairs office memorandum F.No.1/4/2019-NS dated 30 September 2026 keeps all small-savings rates unchanged, and the rate has been 8.2% since 1 January 2024 (memorandum of 29 December 2023). Deposit limits, the 15-year deposit period, the 21-year maturity, the monthly interest rule and the withdrawal rules are from the Sukanya Samriddhi Account Scheme, 2019 (G.S.R. 914(E), 12 December 2019). The rate is reviewed every quarter, so the rate box is editable.

Short answer

At the current 8.2%, ₹1,50,000 paid by 5 April every year for 15 years becomes about ₹71.82 lakh when the account matures 21 years after opening. You put in ₹22.5 lakh; the other ₹49.32 lakh is interest. Deposits run for 15 years from the date of opening, the balance then earns interest for 6 more years, and up to half of it can be taken out for her education once she turns 18.

How the interest is worked out

Paragraph 5 of the scheme sets the method. Each month, the account earns interest on the lowest balance between the close of the 5th and the last day of the month. That interest is added up and credited once a year, on 31 March, rounded to the nearest rupee. That makes the payment date matter more than most calculators show. Money that reaches the account by the 5th earns for that month. Money paid on the 6th earns nothing until the next month.

With ₹1,50,000 a year, the gap is large. Paid by 5 April, each deposit earns for the full year, and the account reaches ₹71,82,127. The same amount split into twelve monthly payments of ₹12,500 reaches ₹69,32,655, about ₹2.5 lakh less. Paid on 31 March, at the end of each year, it reaches ₹66,37,825, about ₹5.4 lakh less. The calculator shows all three every time you change an input.

The rate isn't fixed for the life of the account. The government sets it every quarter, and the new rate applies to the whole balance, not only to new deposits. The 8.2% figure has held since January 2024, but a 21-year projection at today's rate is still only an estimate. Change the rate box to see a lower or higher path.

15 years of deposits, 21 years to maturity

Both periods run from the date the account is opened, not from the financial year. Deposits are allowed until 15 years from opening (paragraph 4(3)), and the account matures 21 years from opening (paragraph 9). From year 16 to year 21 you pay nothing and the balance keeps earning the full rate.

That detail changes the count of yearly deposits. Open in April and pay each April: you make 15 deposits. Open in October and pay at opening, then every April: April of the 15th year still falls inside the 15 years, so you make 16 deposits, one in each of 16 financial years. Most calculators assume 15 equal years from April and miss both the extra deposit and the real maturity month.

If you skip a year, the account goes into default. You can bring it back at any time before the 15 years are up by paying ₹250 for each missed year plus ₹50 a year as a penalty. Under the 2019 rules, a defaulted account still earns the scheme rate on its balance, so the table stays right for the years you do pay.

Withdrawals, early closure and her age

The guardian runs the account until she turns 18; after that she runs it herself. Once she is 18 or has passed Class 10, whichever comes first, she can withdraw up to 50% of the balance as it stood on the previous 31 March, for her education. The college's offer letter or fee slip has to support the amount, and it can be taken in one go or in up to five yearly instalments. The table shows that 50% limit for each year from her 18th birthday, assuming nothing was taken earlier.

The account can close before 21 years in three cases: her marriage after she turns 18 (closure is allowed from one month before to three months after the wedding), her death, or extreme compassionate grounds such as a life-threatening illness, after at least 5 years. Enter her birth month and year and the calculator also checks the age rule: she must not have turned 10 on the day of opening.

Already have an account? Pick the month and year it was opened and enter the balance on 31 March 2026 from the passbook or bank app. The calculator then projects only from April 2026, with the correct last-deposit year and maturity month for your account.

Tax

Interest and the maturity amount are tax-free. Deposits are deductible within the ₹1,50,000 limit of section 123 of the Income-tax Act, 2025 (the old section 80C), but only for someone filing under the old regime; the new regime, which is the default, allows no such deduction.

Worked examples

₹1,50,000 a year, opened in April 2026

Anita opens an account for her daughter, born in June 2024, in April 2026 and pays ₹1,50,000 by 5 April every year. Her last deposit is in April 2040. The account matures in April 2047, when her daughter is 22.

Year 1 earns 8.2% on ₹1,50,000 = ₹12,300, closing at ₹1,62,300. Year 2 earns 8.2% on ₹3,12,300 = ₹25,609. After 15 deposits the balance is ₹44,75,994; six more years of interest take it to ₹71,82,127. She has put in ₹22,50,000. In 2042-43, the year her daughter turns 18, the education withdrawal limit is about ₹24.2 lakh, half of the 31 March 2042 balance.

₹50,000 a year, opened in October 2026

Ravi opens an account in October 2026 for his daughter, born in February 2025, with ₹50,000, and then pays ₹50,000 every April. Because deposits are allowed until October 2041, April 2041 still counts: he makes 16 deposits, ₹8,00,000 in all.

The account matures in October 2047 at ₹25,65,388. Opened in April 2026 with 15 deposits of ₹50,000 instead, the same plan gives ₹23,94,036 in April 2047. Ravi's account matures six months later, with one more ₹50,000 deposit and half a year more interest.

Tips and tricks

Pay by the 5th. A deposit on the 6th earns nothing for that month, and a yearly deposit made in March instead of April loses almost a full year of interest.
If you pay yearly, pay in early April, not at the end of March. For ₹1,50,000 a year, that one habit is worth about ₹5.4 lakh at maturity.
Opening in a month other than April gives a 16th yearly deposit, because the 15 years count from the opening date. Check the "last deposit" line before you stop paying.
Keep paying at least ₹250 every financial year. Reviving a missed year costs only ₹50, but the branch needs a separate request and the missed deposits.
Note the 31 March balance each year. The 50% education withdrawal is worked out from it, so you can plan the fee instalments against a known figure.
Check the rate each quarter. The government reviews it around 31 March, 30 June, 30 September and 31 December, and a change applies to the whole balance.
