An SSY Calculator is an online financial tool designed to estimate the accumulated maturity corpus of a Sukanya Samriddhi account. By inputting your planned annual deposit and child's age, the tool instantly calculates total contributions made over the 15-year payment tenure and the final tax-free corpus upon 21-year maturity.

Key Input Variables & Scheme Features (2026)

1. Current Interest Rate: 8.2% per annum (compounded annually, revised quarterly by the Ministry of Finance).
2. Minimum Deposit: ₹250 per financial year.
3. Maximum Deposit: ₹1,50,000 per financial year.
4. Deposit Tenure: 15 years from the account opening date.
5. Maturity Period: 21 years from the date of account opening.
6. Tax Status: EEE (Exempt-Exempt-Exempt) — tax deduction on deposits under Section 80C, tax-free interest, and tax-free maturity payout.

How the SSY Calculation Works

The SSY calculator uses compound interest to project growth. Contributions are made for the first 15 years, while the accumulated sum continues to earn compounding interest for the remaining 6 years until full maturity at 21 years.

$$\text{Balance for Contribution Years } (Y = 1 \text{ to } 15): B_Y = (B_{Y-1} + D) \times (1 + r)$$

$$\text{Balance for Non-Contribution Years } (Y = 16 \text{ to } 21): B_Y = B_{Y-1} \times (1 + r)$$

Where:

1. $B_Y$ = Account balance at the end of year $Y$
2. $D$ = Annual deposit amount
3. $r$ = Annual interest rate (e.g., $0.082$ for 8.2%)

Estimated Maturity Returns Table (at 8.2% Interest)

Note: Calculations assume equal annual deposits made before April 5th each year at a constant 8.2% rate.

Key Eligibility & Withdrawal Rules

1. Age Limit: Girl child must be an Indian resident under 10 years of age at account opening.
2. Account Limit: Maximum 2 accounts per family (exceptions allowed for twins/triplets).
3. Higher Education Withdrawal: Up to 50% of the balance can be withdrawn after the girl child turns 18 or completes 10th grade.
4. Premature Closure: Allowed for the girl child's marriage after age 18, or under special compassionate grounds (e.g., medical emergency, death).

Smart Tips to Maximize SSY Returns

1. Deposit Before the 5th of April: Interest is calculated on the lowest balance between the 5th and the end of each month. Depositing annually between April 1st and April 5th maximizes interest accrual for the full year.
2. Invest Early: Opening the account right after birth gives the fund the maximum time to compound.
3. Maximize Contributions: Utilize the full ₹1.5 lakh cap if possible to create a substantial corpus for higher education costs.
