How we calculate this
Deposits are allowed for 15 years from the opening date; the account matures 21 years after opening. Each month earns interest on the lowest balance between the 5th and the month end. Monthly interest = that balance × rate ÷ 12, credited each 31 March, rounded to the rupee. After deposits stop, the balance keeps earning until maturity.
Calculation version 0.3 · Rate 8.2% confirmed up to 31 Dec 2026 (Ministry of Finance (DEA) office memorandum of 30 Sep 2026, in India Post SB Order 12/2026, checked 7 Oct 2026); after that, the rate you assume. Assumption: interest is counted up to the end of the month before maturity and paid at maturity (the scheme text doesn't say how the maturity month is treated). Withdrawals for education, early closure and penalties aren't covered.

How to read your Sukanya Samriddhi projection
The Sukanya Samriddhi Account (SSY) is a government savings account opened in the name of a girl under 10. This tool splits the plan into two parts: the years you pay in, and the years the balance keeps growing without new deposits.
What the numbers mean
Last deposit by is 15 years from the opening date. After it, the tool adds no more deposits. Matures is 21 years from the opening date. It is not the date she turns 21. A girl who is 4 when the account opens will be about 25 at maturity.
You put in adds up all deposits. Projected balance is the amount at maturity, with the interest shown underneath. If part of the period falls after 31 Dec 2026, the note says the result includes your assumed rate.
The table goes year by year, by financial year (1 April to 31 March). The row marked “last deposits” is where paying in stops. The rows after it show interest only.
How the official rules work
Under the Sukanya Samriddhi Account Scheme, 2019:
- The girl must be under 10 on the opening date. Each girl can have only one account.
- Deposits are ₹250 to ₹1,50,000 each financial year, in multiples of ₹50. Money above the limit earns no interest and is returned.
- Interest for a month is paid on the lowest balance between the close of the 5th and the end of the month, so money in by the 5th earns that month. This is the same day-5 rule PPF uses.
- Interest is credited at the end of each financial year and rounded to the rupee (50 paise or more rounds up).
The rate is 8.2% a year for 1 Oct to 31 Dec 2026, unchanged since 1 Jan 2024. The government reviews it every quarter. For later periods, the tool uses the rate you type in, which is your own assumption.
One point is not settled. The scheme text doesn’t say how interest works in the maturity month itself. We count interest up to the end of the month before maturity and add it at maturity. The page lists this as an assumption.

Worked example
A fictional account opened on 7 Oct 2026 for a girl aged 4. It starts with ₹1,50,000, then ₹1,50,000 goes in on 1 April each year. We assume 8.2% stays the same after 2026.
| Result | Value |
|---|---|
| Last deposit by | 7 Oct 2041 |
| Deposits | 16, so ₹24,00,000 in total |
| Matures | 7 Oct 2047 |
| Projected balance | ₹76,91,014 |
| Interest | ₹52,91,014 |
The first credit, on 31 Mar 2027, is ₹5,125. October earns nothing, because the first deposit came on the 7th. The balance includes ₹3,02,912 of interest for April to September 2047, paid at maturity under the assumption above. If each April deposit came on the 6th instead of the 1st, the projection would be ₹43,640 lower.
What this tool doesn’t do
It assumes you make every yearly minimum deposit and take nothing out. Withdrawals for her education, closure for marriage, early closure and the penalty for a missed year aren’t covered. It doesn’t work out tax. It never asks for her name or date of birth, only her age at opening.

Frequently asked questions
Until when do I have to deposit in Sukanya Samriddhi?
Deposits are made for 15 years from the opening date. The period counts from the date you open the account, not by financial year. For an account opened on 7 Oct 2026, the last deposit date is 7 Oct 2041. After that, you stop paying in, but the balance keeps earning interest until maturity. The calculator marks the year your deposits end.
Does SSY mature when my daughter turns 21?
No. The account matures 21 years from the opening date, whatever her age. If you open it when she is 4, it matures when she is about 25. For an account opened on 7 Oct 2026, maturity is 7 Oct 2047. That is why the calculator asks only for her age at opening, to check she is under 10.
How much can I deposit in SSY each year?
You can deposit ₹250 to ₹1,50,000 each financial year (April to March), in multiples of ₹50. You can pay once or in parts, but all deposits in the year count towards the limit. Money above ₹1,50,000 earns no interest and is returned to you. The calculator stops a monthly plan that adds up to more than the limit.
What is the SSY interest rate?
The rate is 8.2% a year for 1 Oct to 31 Dec 2026, unchanged since 1 Jan 2024. The government reviews it every quarter. For any period after 31 Dec 2026, the calculator uses the rate you type in, and that is your own assumption. In our fictional example, ₹1,50,000 a year from 7 Oct 2026 projects to ₹76,91,014, if 8.2% stays the same.
Does the deposit date matter in SSY?
Yes. Interest for a month is paid on the lowest balance between the close of the 5th and the month end. Money paid in by the 5th earns that month; money paid later waits for the next month. In our example, paying each April deposit on the 6th instead of the 1st lowers the projection by ₹43,640.
