Highlighted cell matches your current inputs. Shows how maturity value shifts if the quarterly rate changes over the 21-year horizon.

📐 Mathematical Methodology & Verification

Each year: Balance = (Opening Balance + Annual Deposit) × (1 + r)
where r = annual SSY rate; deposits only occur in years 1–15, years 16–21 compound with zero deposit
Maturity Corpus = Balance after 21 such annual cycles

Simplification disclosed: this calculator applies a full year's interest to each year's deposit, as if it were made on day one. In practice, SSY interest is computed on the lowest balance between the 5th and last day of each calendar month, so your actual passbook figure may differ slightly depending on when in the year you deposit.
Client-Side Execution: All calculations run locally in your browser. No financial data is transmitted.
Rate Volatility: unlike annual tax-rate changes, the SSY rate is reviewed every quarter — a 21-year projection at today's rate is a starting estimate, not a guarantee for the full tenure.

How Sukanya Samriddhi Yojana (SSY) Works

Sukanya Samriddhi Yojana (SSY) is a government of India backed small-deposit savings scheme launched under the Beti Bachao, Beti Padhao initiative, designed to help parents build a dedicated, high-interest corpus for their daughter's higher education and marriage.

The 15 vs. 21 Year Compounding Rule

Many investors mistakenly assume deposits are required for 21 years. Under official SSY rules: you deposit annually for the first 15 years (Deposit Phase), then the account keeps compounding with zero further deposits until it completes 21 years from opening (Growth Phase).

Can I make partial withdrawals from SSY before 21 years? ▼

Yes, once the girl child attains 18 years of age or completes 10th standard, up to 50% of the account balance at the end of the preceding financial year can be withdrawn to fund higher education expenses.
