Sukanya Samriddhi Yojana is a government-backed savings scheme aimed at promoting the education and financial security of the girl child. Under this scheme, parents or guardians can open a Sukanya Samriddhi account in the name of a girl child who is less than 10 years old. The account can be opened at any post office or authorized bank, and a minimum deposit of INR 250 (or higher, in multiples of INR 50) must be made to open the account.

To calculate the maturity amount of a Sukanya Samriddhi account, you can use the following formula:

Maturity amount = [(Deposit amount + Interest earned) * (1 + Rate of interest) ^ (Number of years)]

where:

• Deposit amount is the total amount of money deposited in the Sukanya Samriddhi account.
• Interest earned is the total interest earned on the account over the years.
• Rate of interest is the interest rate applied to the account. This rate is revised by the government every year and is currently set at 7.6% per annum.
• Number of years is the number of years for which the account has been open.

For example, if you open a Sukanya Samriddhi account with a deposit of INR 50,000 and keep it open for 15 years, the maturity amount would be calculated as follows:

Maturity amount = [(50000 + (50000 * 7.6% * 15)) * (1 + 7.6%) ^ 15] = INR 1,56,080

It’s important to note that the Sukanya Samriddhi account matures when the girl child turns 21 years old, and the account must be closed at that time. The account can also be closed earlier in case of the death of the girl child or if the account holder becomes disabled.
