Sukanya Samriddhi Yojana Calculator

You stop depositing at year 15. The account doesn't stop growing until year 21.

That six-year gap is the part parents most often miss when they estimate SSY by hand. Deposit the maximum ₹1,50,000 every year at the current 8.2% rate, and total contributions across the 15 deposit-years add up to ₹22,50,000 — but the account keeps compounding, untouched, for a further six years before it finally matures. By year 21, the projected maturity value is ₹71,82,119, which means ₹49,32,119, more than double what was actually deposited, is pure interest.

Why the calculation has two distinct phases

For the first 15 years, this calculator adds each year's deposit to the balance before that year's interest is applied — the same mechanism as PPF. But unlike PPF, deposits then stop entirely while the account remains open for six more years, simply compounding on whatever balance already exists at the same rate, with no further contributions required or even allowed. A meaningful share of the final corpus is actually built in those last six no-deposit years, purely because a larger balance is now compounding on itself with nothing added or withdrawn.

What makes SSY worth the 21-year commitment

Sukanya Samriddhi carries EEE tax status — deposits are deductible under Section 80C, the interest is entirely tax-free, and so is the maturity payout — layered on top of one of the highest interest rates offered by any small savings scheme in India, backed by the government. The account must be opened before the girl turns 10, which makes timing the one irreversible decision in this whole calculation: open it later and there are fewer years for the six-year uncompensated tail to work its magic before she needs the funds for higher education or marriage expenses.
