This assumes each yearly deposit is made at the start of the year and interest compounds annually, the convention the leading calculators use. The real account credits interest on the lowest balance between the 5th and month-end, so depositing before the 5th (and before 1 April each year) earns the most. Rates are revised quarterly, so a long-horizon figure is an estimate, not a guarantee. This is an educational tool, not financial advice.
How the calculator works
SSY runs on annual compounding over a 21-year life, with deposits allowed only in the first 15 years. The calculator applies each year's deposit at the start of the year, adds one year of interest at the SSY rate, and carries the balance forward. In the final 6 years the deposit is zero, but the balance still earns interest, which is the scheme's quiet advantage over a plain 15-year plan.
Years 1 to 15: balance = (balance + deposit) * (1 + r)
Years 16 to 21: balance = balance * (1 + r)Here r is the rate as a decimal, so 8.2% becomes 0.082. The real account calculates interest on the lowest balance between the 5th and the last day of each month and credits it once a year, so depositing before the 5th of the month (and before 1 April for a yearly lump sum) earns the most. The start-of-year model matches that best case and lines up with the leading calculators.
A worked example
Take the maximum deposit of ₹1.5 lakh a year at the current 8.2% rate, opened in 2026:
- Yearly deposit: ₹1,50,000 for 15 years
- Total deposited: ₹22,50,000
- Maturity in 2047: about ₹71,82,127, fully tax-free
- Tax-free interest earned: about ₹49,32,127
Scale it down and the proportion holds, because SSY is fixed-rate. ₹50,000 a year grows to about ₹23,94,036 on ₹7,50,000 deposited. ₹1 lakh a year grows to about ₹47,88,077. The single biggest lever is time: more than a third of the final balance is built in the 6 years after deposits stop, purely from compounding.
Why some calculators show a different number
If another SSY calculator shows about ₹69 lakh for the same ₹1.5 lakh a year at 8.2%, it is using a different deposit-timing assumption, not a different rate. This calculator, like ClearTax and Stable Investor, assumes the deposit is made at the start of the year, so it earns a full year of interest. Calculators that assume an end-of-year or minimum-balance timing show a slightly lower figure. The gap is about one year of interest on the deposits, and your real number depends on when in the year you actually pay in.

Frequently asked questions
What is the current Sukanya Samriddhi Yojana interest rate?
The current SSY interest rate is 8.2% per year for the July to September 2026 quarter (Q2 FY 2026-27), compounded annually. The Ministry of Finance sets the rate every quarter, and it has held steady at 8.2% since April 2024, roughly 1.1 percentage points above PPF's 7.1%. Because the rate can change each quarter, the calculator lets you edit it, so you can model a lower or higher rate over the long 21-year horizon rather than assuming today's rate holds for two decades.
How is the SSY maturity amount calculated?
SSY maturity is calculated with annual compounding over a 21-year account life, where deposits are made only in the first 15 years and the balance compounds untouched for the final 6 years. The calculator applies each year's deposit at the start of the year, so it earns a full year of interest, then adds the year's interest to the balance: balance becomes (previous balance plus deposit) times 1.082 for years 1 to 15, and previous balance times 1.082 for years 16 to 21. At the maximum ₹1.5 lakh a year and 8.2%, that produces ₹71,82,127 at maturity on ₹22,50,000 deposited.
Why does the calculator stop deposits after 15 years?
SSY requires deposits only during the first 15 financial years from account opening, but the account does not mature until 21 years. Those extra 6 years are a defining feature of the scheme: the accumulated balance keeps earning the SSY rate with no fresh contributions, which is why the year-by-year table shows a deposit of zero from year 16 while the balance still climbs. The calculator models this automatically, so the maturity figure already includes the 6 no-deposit compounding years.
How much does ₹1.5 lakh a year grow to in SSY?
At the maximum deposit of ₹1.5 lakh a year for 15 years and the current 8.2% rate, a Sukanya Samriddhi Yojana account grows to about ₹71,82,127 at the 21-year maturity. The total deposited is ₹22,50,000, so the tax-free interest earned is roughly ₹49,32,127, more than double the amount put in. A smaller ₹50,000 a year grows to about ₹23,94,036 on ₹7,50,000 deposited, and the relationship is proportional because SSY is a fixed-rate scheme.
Is the SSY maturity amount taxable?
No, the SSY maturity amount is fully tax-free. The scheme carries EEE (Exempt-Exempt-Exempt) status: deposits qualify for a deduction of up to ₹1.5 lakh a year under Section 80C, now renumbered Section 123 under the Income Tax Act 2025 that took effect on 1 April 2026, and this deduction is available only under the old tax regime. The annual interest and the final maturity amount are both exempt from income tax. That tax-free treatment is what makes the 8.2% rate more valuable than a taxable fixed deposit at the same headline rate.
Why do some SSY calculators show ₹69 lakh instead of ₹71.82 lakh?
The difference comes from the deposit-timing assumption, not the interest rate. Calculators that assume the yearly deposit is made at the start of the year (the convention ClearTax, Stable Investor, and this calculator use) show about ₹71.82 lakh for ₹1.5 lakh a year at 8.2%. A few calculators assume an end-of-year or minimum-balance timing and show closer to ₹69 lakh for the same inputs. Both use 8.2%; the gap is roughly one year of interest on the deposits. Your real figure depends on when in each year you actually deposit.
