SSY Calculator — Plan Your Daughter's Financial Future With Sukanya Samriddhi Yojana
Sukanya Samriddhi Yojana (SSY) is one of the most rewarding savings schemes a parent can use for a girl child's future — combining a sovereign government guarantee, one of the highest interest rates among small savings instruments (8.2% p.a. as of 2024), and complete EEE tax status (contributions deductible under 80C, interest tax-free, maturity amount tax-free). This SSY Calculator shows you exactly how your annual deposits compound over the scheme's 21-year horizon, with a year-by-year breakdown of opening balance, investment, interest earned, and closing balance — plus an optional inflation adjustment to understand the real purchasing power of your maturity corpus.
Enter your annual deposit amount (₹250 to ₹1,50,000) and the start year. The calculator applies the current SSY rate and builds a complete schedule through the 15 deposit years and the remaining 6 years of passive compounding until maturity — giving you the total invested, total interest earned, and the final maturity value.
The SSY Formula and How Compounding Works Over 21 Years
SSY interest is calculated on the minimum balance between the 5th and last day of each calendar month, then summed and credited at the end of the financial year. For planning purposes, the annual compounding formula is:
F = P × [((1 + r)n − 1) ÷ r] × (1 + r)
Where P = annual deposit, r = annual interest rate (8.2% = 0.082), n = number of deposit years (15). Total tenure is 21 years — you deposit for 15 years, then the balance compounds for 6 more years without any new deposits.
Example: ₹1,50,000/year for 15 years at 8.2%. Total invested = ₹22,50,000. Maturity amount after 21 years ≈ ₹71,82,119. Tax-free interest earned ≈ ₹49,32,119 — more than double the amount you invested, entirely free of tax. The 6 years of passive compounding after the 15th deposit year account for a significant portion of this gain.
SSY's Critical Rule: Deposit Before 5 April Every Year
Identical to PPF, SSY interest is calculated on the minimum balance from the 5th to the last day of each month. Depositing before 5 April (start of the financial year) means your full annual deposit earns interest for the entire year. Depositing after 5 April loses that month's interest on the new deposit. Over 15 years, consistently depositing before 5 April can add ₹2–4 lakh to your final corpus on maximum annual contributions — a difference worth maintaining.
SSY vs PPF vs ELSS — Choosing the Right Long-Term Scheme for a Girl Child
SSY vs PPF: SSY currently offers 8.2% vs PPF's 7.1% — a 1.1% advantage that compounds significantly over 21 years. Both have EEE tax status. SSY is exclusively for girl children (under 10 at account opening); PPF is for any individual. The higher SSY rate makes it the preferred instrument specifically for a daughter's education and marriage corpus. However, SSY has a fixed 21-year tenure and less liquidity than PPF.
SSY vs ELSS: ELSS can deliver 12–15% CAGR over long periods but returns are not guaranteed and involve market risk. SSY's 8.2% is fixed and guaranteed — in a 2008-style market crash that hits a 21-year ELSS portfolio, SSY would outperform significantly. For parents with low risk tolerance or who specifically need a predictable corpus for their daughter at 18–21, SSY is the safer, more appropriate choice. Many parents use both: SSY for the guaranteed base and an ELSS SIP for the higher-growth component.
Partial Withdrawal and Premature Closure Rules
Partial withdrawal at 18: After the girl turns 18 (and the account is at least 5 years old), you can withdraw up to 50% of the balance at the end of the preceding financial year. This can be used for higher education expenses. The withdrawal can be taken as a lump sum or in up to 5 annual instalments.
Account closure at marriage: The account can be closed prematurely on the girl's marriage after she turns 18, provided the account has been open for at least 5 years. The full balance is paid out tax-free on marriage — this makes SSY uniquely useful as a marriage fund that also serves as an education fund.
Premature closure (other cases): Allowed only for: death of the account holder, life-threatening disease of the account holder, death of the guardian, or extreme financial hardship (subject to approval). On premature closure for other reasons, interest is paid at post office savings rate (not SSY rate) — a significant penalty.
