Sukanya Samriddhi Yojana Calculator Formula Explained

Our Sukanya Samriddhi Yojana calculator uses the same formula as leading financial calculators. Your yearly deposit is split into 12 equal monthly deposits. Each monthly deposit compounds at the effective monthly interest rate derived from the annual 8.2% rate.

Deposits are made for the first 15 years (180 monthly deposits). After that, the accumulated corpus continues to earn interest for 6 more years until maturity at 21 years from account opening.

For example, if you deposit ₹1,00,000 every year at 8.2%, the Sukanya Samriddhi Yojana calculator shows a maturity value of approximately ₹46.19 lakh — that’s ₹15 lakh of your own deposits plus ₹31.19 lakh earned as interest.

SSY vs PPF: Which Gives Better Returns?

One unique feature of our Sukanya Samriddhi Yojana calculator is the built-in PPF comparison. SSY offers 8.2% while PPF offers 7.1% (2026 rates). On a ₹1 lakh yearly deposit, SSY gives you approximately ₹46.19 lakh versus PPF’s ₹27.10 lakh — a difference of over ₹19 lakh!

This makes SSY the clear winner for eligible girl children. The calculator’s visual comparison bars make this difference instantly clear.

Tax Benefits Calculated Automatically

The Sukanya Samriddhi Yojana calculator includes a tax savings estimator. Select your tax slab to see how much you’ll save through Section 80C deductions over 15 years. For someone in the 20% slab depositing ₹1.5 lakh yearly, that’s ₹4.5 lakh in total tax savings.

Remember, SSY enjoys EEE (Exempt-Exempt-Exempt) status — deposits qualify for 80C deduction, interest is tax-free, and the maturity amount is completely tax-free. Learn more about SSY on the official India Post website.
