How the scheme works
Deposits are made for the first 15 years after opening. The account then keeps earning interest until it matures 21 years from the date of opening. At ₹1,50,000 a year for 15 years you deposit ₹22,50,000, and at 8.2% the estimated maturity amount is ₹71,82,119, so the interest earned is ₹49,32,119.
A girl who opens the account at age 2 will be 23 years old at maturity. Partial withdrawals for education are allowed after she reaches 18 under the scheme’s rules.
What the calculator assumes
The calculator assumes one deposit at the start of each financial year, which earns interest for the full year. In practice, interest is worked out each month on the lowest balance between the 5th and the end of the month and credited at year end, so depositing early in April and before the 5th of each month gives the best result.
If you deposit later in the year or in smaller amounts, the real maturity amount will be somewhat lower than the estimate here.
Deposit size and interest rate
Smaller deposits scale down proportionally: ₹50,000 a year gives about ₹23,94,040, and ₹1,000 a year about ₹47,881. The table above shows a few more levels.
The interest rate changes the result noticeably. The rate was 8.2% for October to December 2026, and at 7.5% the ₹1,50,000 plan would mature at about ₹64,99,748. The rate for new and existing accounts changes with each quarterly announcement.
Rules to check
The annual deposit limit is ₹1.5 lakh and the minimum is ₹250 each year. Missing the minimum puts the account in default, which can be restored with a small penalty. The scheme’s tax treatment, limits and eligibility are set by the government and can change, so confirm them with the post office or your bank.
The SSY is for one girl child per family under the standard rules, with limits on the number of accounts. This tool is an estimate and not an official statement of your account.
