Sukanya Samriddhi maturity value
$1,50,000 deposited by 5 April every year for 15 years at 8.2%, account opened when she is 2
Sukanya Samriddhi maturity
- D
- the deposit each financial year, for the first 15 years
- r
- the annual rate as a decimal. Interest is r ÷ 12 a month on the month’s lowest balance after the 5th, added once a year, so the balance compounds yearly.
- k
- how much of a year’s interest each deposit earns in its own year: 1 + r if paid by 5 April; 1 + 13r ÷ 24 if paid monthly by the 5th; 1 if paid after 5 March
- M
- the balance 21 years after opening: six more years of interest on the year-15 balance, with no deposits
Worked example
$1,50,000 deposited by 5 April every year for 15 years at 8.2%, account opened when she is 2
1.08215 = 3.2614
Balance after 15 years = 1,50,000 × 1.082 × (3.2614 − 1) ÷ 0.082 = $44,75,989
Six more years of interest: × 1.0826 = × 1.6046
M = $71,82,119, when she is 23
Deposited $22,50,000; interest $49,32,119
In today's money at 4% inflation: $31,51,755

How a Sukanya Samriddhi account grows
A Sukanya Samriddhi account is opened by a parent or guardian for a girl under ten. Under the Sukanya Samriddhi Account Scheme, 2019 you pay in between ₹250 and ₹1,50,000 in each financial year for the first fifteen years, and the account matures twenty-one years after it was opened. For the last six years no deposits are due, but the balance keeps earning interest — which is why so much of the final value arrives late. In the example, the balance after fifteen years is $44,75,989; six more years of interest take it to $71,82,119.
Interest follows the same rule as PPF: each month earns interest on the lowest balance between the close of the fifth day and the end of the month, and the year’s interest is added at the end of the financial year. So the balance compounds once a year, and money paid in by 5 April earns a full year’s interest while money paid after 5 March earns none that year. Paying $1,50,000 at the end of each year instead of by 5 April costs $5,44,301 by maturity.
The rate is set by the government every quarter. It is 8.2% a year for July–September 2026, unchanged from the previous quarter, under the Ministry of Finance’s office memorandum of 30 June 2026; the next rate is due at the end of September. Unlike a National Savings Certificate or a time deposit, the Sukanya Samriddhi rate is not locked when you open the account: like PPF, each new quarterly rate applies to the whole balance. This projection holds one rate for twenty-one years, so treat it as an estimate.
Once she turns eighteen or passes class ten, whichever comes first, up to half of the balance at the end of the previous financial year can be withdrawn for her education. The account can also be closed early for her marriage after eighteen. This page shows the balance at the end of the year she turns eighteen, so you can see roughly what half of it would be; any withdrawal reduces the maturity value.
Tax: interest and the maturity amount have been exempt, and deposits have qualified for a deduction only under the old tax regime. The Income-tax Act, 2025 took effect on 1 April 2026 with new section numbers, so check the current position. Twenty-one years is a long time for inflation: at 4% a year the example’s maturity value is worth about $31,51,755 in today’s money. Compare the PPF calculator for your own account, or the SIP calculator for a market-linked alternative. This is arithmetic on the figures you enter, not financial advice.
Frequently asked questions
What is the Sukanya Samriddhi interest rate now?
8.2% a year, compounded yearly, for July–September 2026 (Ministry of Finance office memorandum of 30 June 2026). The government reviews it every quarter, and the new rate applies to existing accounts as well.
What will 1.5 lakh a year in Sukanya Samriddhi become?
About $71,82,119 after 21 years at 8.2%, if paid by 5 April each year for 15 years: $22,50,000 deposited and $49,32,119 interest.
For how many years do I have to deposit?
Fifteen years from opening. The account then earns interest without deposits until it matures, 21 years after opening.
When can money be withdrawn?
After she turns 18 or passes class 10, whichever is earlier, up to 50% of the balance at the end of the previous financial year, for education. The account can be closed for her marriage after 18.
Why does another calculator give a different figure?
Usually because it assumes deposits at a different time of year, or compounds monthly. The scheme adds interest once a year, on each month’s lowest balance after the 5th.
