About this calculator
Enter the yearly deposit and the girl’s age. The calculator shows the maturity value, how much is deposits and how much is interest, and the balance for every year. It starts at 8.2%, the rate notified for October to December 2026.
How to use it
- Enter the amount you will deposit each financial year, between ₹250 and ₹1,50,000.
- Enter the girl’s age when the account is opened, to see the age at maturity.
- Leave the rate at 8.2% or try other rates.
- Read the maturity value and the yearly table.
The formula
- deposit
- the yearly amount in years 1 to 15; zero in years 16 to 21
- i
- the yearly rate as a decimal (8.2% = 0.082)
The rule is repeated for 21 years. Deposits are taken to be made at the start of each financial year, before 5 April.
Worked example
₹1,50,000 a year at 8.2%
- Deposits for 15 years: 15 × 1,50,000 = ₹22,50,000.
- The balance keeps growing at 8.2% until year 21, with no deposits in years 16 to 21.
- Maturity value: ₹71,82,119, of which ₹49,32,119 is interest.
What the result means
The last six years add a large share of the interest even though no money goes in, because the whole balance keeps compounding. That is why SSY rewards starting early.
SSY has been tax-free on maturity, and deposits can qualify for a deduction under the old tax regime. Check the tax rules for your year, as the deduction is not available under the new regime.
Assumptions
- The same amount is deposited every year for 15 years, on or before 5 April.
- The rate stays the same for 21 years.
- No withdrawals are made before maturity.
Limitations
- The government reviews the SSY rate every quarter, and the new rate applies to the whole balance.
- Real accounts work out interest monthly on the lowest balance between the 5th and the end of the month, so late deposits earn less.
- Partial withdrawal for education after she turns 18 and early closure on marriage are not modelled.
Frequently asked questions
What is the Sukanya Samriddhi interest rate now?
8.2% a year for October to December 2026, unchanged in the Finance Ministry notification of 30 September 2026.
For how many years do I need to deposit?
For 15 years from the date the account is opened. The account then earns interest until it matures at 21 years.
Who can open an SSY account?
A parent or legal guardian, for a girl below 10 years of age, at a post office or an authorised bank. A family can usually open accounts for up to two girls.
Is SSY better than PPF?
SSY currently pays a higher rate (8.2% against 7.1%), but it can only be used for a girl child and the money is locked in longer. Many parents use both.
