How it works
A Sukanya Samriddhi account is opened for a girl child under 10. Deposits of ₹250 to ₹1,50,000 a year can be made for 15 years from opening.
After the deposits stop, the account keeps earning interest until it matures, 21 years after it was opened.
The government sets the rate every quarter. This calculator uses one rate for all years, so change it to see other cases.
The calculation assumes a deposit made by 5 April each year, so the full year earns interest. Interest is added at the end of each financial year.
The formula
Year-end balance = (opening balance + deposit) × (1 + rate)
Deposits are made for the first 15 years only. For years 16 to 21 the balance grows with no deposit.
A worked example
Depositing ₹1,50,000 every year for 15 years at 8.2% means you put in ₹22,50,000 in total, and the account grows to about ₹71.8 lakh by year 21.
Frequently asked questions
What is the current Sukanya Samriddhi rate?
The rate is 8.2% a year for October to December 2026, unchanged from the previous quarter. It can change every quarter.
Can money be withdrawn before 21 years?
A part of the balance can be withdrawn after the girl turns 18, for education or marriage, under the scheme’s rules. The full amount is paid at maturity. Check the current rules at your bank or post office.
Is the interest taxable?
Under current rules, the deposits qualify for a deduction under Section 80C (old regime), and the interest and maturity amount are tax free. Rules can change.
Why does my passbook show a different amount?
Rates change quarterly and interest is worked out monthly on the lowest balance. The date you deposit also matters. Treat this as an estimate.
