What is the SSY Calculator?
The Sukanya Samriddhi Yojana (SSY) Calculator helps Indian parents and guardians estimate the maturity corpus for their girl child's future — be it higher education or marriage expenses. Launched under the Beti Bachao Beti Padhao initiative by the Government of India, SSY is one of the most rewarding small savings schemes available today, currently offering an interest rate of 8.2% per annum (for FY 2025-26 and Q1 FY 2026-27), compounded annually. The calculator lets you instantly see how your annual deposits will grow over the scheme's tenure without doing any manual math.
Unlike generic investment calculators, the SSY Calculator is tailored to the specific rules of the scheme: accounts can be opened for a girl child below the age of 10, deposits are mandatory only for 15 years from the date of account opening, yet the account matures after 21 years. Interest accrues for all 21 years even after the deposit window closes, which makes this a genuinely powerful long-term wealth-building instrument. The calculator accounts for this unique structure so you get an accurate projection.
For Indian families with daughters, SSY also delivers a triple tax benefit under Section 80C (deduction up to ₹1.5 lakh per year), tax-free interest, and tax-free maturity proceeds — making it an EEE (Exempt-Exempt-Exempt) instrument. No other fixed-income government scheme offers this combination of safety, returns, and tax efficiency, which is why understanding projected outcomes through this calculator is essential before you decide how much to deposit each year.
How does it work?
The SSY Calculator uses annual compound interest to project the maturity amount. The formula applied is: A = P × (1 + r)^n, where P is the annual deposit, r is the annual interest rate (currently 8.2% or 0.082), and n is the number of years the deposit remains invested. Because you deposit every year for 15 years but each deposit earns interest for a different number of years (the first deposit earns interest for 21 years, the second for 20 years, and so on up to the 15th deposit which earns interest for 7 years), the total maturity value is the sum of these individual future values. Interest continues to accrue on the accumulated balance for the remaining 6 years (years 16–21) even though no new deposits are made.
The key inputs are: (1) Annual deposit amount — the amount you invest each financial year, with a minimum of ₹250 and a maximum of ₹1,50,000; (2) Girl child's current age — this determines the account tenure remaining; (3) Interest rate — currently fixed at 8.2% p.a., revised by the government quarterly. The calculator also uses the account's date of opening (or the child's age as a proxy) to calculate exactly how many years of compounding each deposit will receive.
It is important to understand that SSY interest is calculated on the lowest balance between the 10th and last day of each calendar month, but for projection purposes annual compounding gives you a very close approximation. The government revises SSY rates every quarter; the calculator uses the current applicable rate of 8.2% p.a. If rates change in future quarters, your actual maturity amount may differ slightly from the projection.
Worked example
Consider Priya Sharma, a homemaker in Pune whose daughter Ananya was born in March 2023. Priya opens an SSY account in April 2025, when Ananya is 2 years old. She decides to deposit the maximum ₹1,50,000 every financial year. Using the SSY Calculator at the current rate of 8.2% p.a., her first deposit of ₹1,50,000 made in FY 2025-26 will compound for 21 years and grow to approximately ₹7,68,600. Her 15th and final deposit made in FY 2039-40 will compound for 7 years and grow to approximately ₹2,60,400. Adding up the future values of all 15 deposits, Priya's total maturity corpus at the end of 21 years (in 2046, when Ananya is 21) would be approximately ₹69.8 lakh against a total investment of just ₹22.5 lakh — a wealth multiple of over 3x.
If Priya can only invest ₹50,000 per year, the estimated maturity corpus drops to roughly ₹23.3 lakh, still a meaningful fund for Ananya's college education or wedding. This example illustrates the power of starting early and maximising contributions; even a modest but consistent deposit, when compounded at 8.2% over two decades, creates a substantial tax-free fund that no market-linked instrument can match on a risk-adjusted basis for this specific purpose.
When to use this calculator
- 1When you have just had a baby girl or your daughter is below the age of 10 and you want to understand how much to set aside each year to fund her higher education — engineering, medicine, or an MBA — 18–21 years from now.
- 2When you are planning your annual Section 80C investments and want to compare how much SSY will accumulate versus PPF or ELSS to decide where to allocate your remaining ₹1.5 lakh deduction limit.
- 3When your daughter is already 7 or 8 years old and you want to check if it is still worthwhile to open an account now, or whether starting late significantly reduces the corpus given the shorter compounding window.
- 4When you want to visualise the impact of depositing the minimum ₹250 per year versus the maximum ₹1,50,000 per year, to find a deposit level that fits your monthly household budget without sacrificing long-term returns.
- 5When you are a grandparent or relative planning to gift a lump sum to a girl child's SSY account and need to know the projected value to decide the gift amount.
Common mistakes to avoid
- ✕Opening the account too late: Many parents wait until the child is 7 or 8 years old, unaware that every year of delay significantly reduces the compounding period. An account opened at birth can compound for 21 years; one opened at age 9 competes only 12 years of deposits and 21 years total from opening, but you lose 9 years of early compounding on the first few deposits.
- ✕Depositing the minimum just to keep the account active: SSY requires a minimum ₹250 deposit per year to avoid the account becoming irregular (a penalty of ₹50 per year is levied on dormant accounts). Many families deposit only ₹250 not realising they could invest up to ₹1.5 lakh and earn 8.2% guaranteed — far better than most FDs.
- ✕Missing the deposit window between April 1 and April 5: SSY interest is calculated on the balance on the 5th of each month. Depositing early in April means your deposit earns interest for the entire month of April rather than from the date you deposit later in the month, reducing overall returns marginally but consistently over 15 years.
- ✕Confusing the lock-in with total maturity: Parents sometimes assume they can withdraw funds after 15 years (when deposits stop). The account actually matures after 21 years from opening, and premature full withdrawal is only allowed in specific circumstances such as the account holder's marriage after age 18 or a medical emergency.
- ✕Not claiming the Section 80C deduction: A surprising number of SSY account holders forget to include their SSY deposits in their ITR under Section 80C, leaving tax savings of up to ₹46,800 per year (for those in the 30% bracket) unclaimed.
Frequently asked questions
- What is the current SSY interest rate for FY 2026-27?
- The Sukanya Samriddhi Yojana interest rate for Q1 FY 2026-27 (April–June 2026) is 8.2% per annum, compounded annually. The government reviews this rate every quarter. It has remained at 8.2% since January 2024. Always check the Ministry of Finance notification for the current quarter before making large deposits, as the rate applicable to your balance is the rate announced for that quarter.
- Can I open more than one SSY account for my daughter?
- No. Only one SSY account is permitted per girl child. A family can open a maximum of two SSY accounts — one for each of two daughters. An exception exists for twins or triplets born in the second birth: if the second birth results in twin or triplet girls, a third account is permitted with documentary proof. Opening duplicate accounts is illegal, and if discovered, the second account is regularised as a normal savings account earning post-office savings rates.
- What happens to the SSY account if I miss a deposit in a particular year?
- If you fail to deposit at least ₹250 in any financial year, your SSY account becomes 'irregular' or 'defaulted'. You can revive the account by paying the outstanding minimum deposits for each missed year along with a penalty of ₹50 per year of default. This revival must be done before the 15-year deposit window closes. Interest continues to accrue on the existing balance even on a defaulted account, but you lose the benefit of fresh deposits compounding over the remaining tenure.
- Can I withdraw from SSY before maturity for my daughter's college education?
- Yes. A partial withdrawal of up to 50% of the balance as of the end of the previous financial year is permitted once the girl child turns 18, specifically for the purpose of higher education. You must submit proof of admission to a recognised institution (offer letter or fee receipt). This partial withdrawal does not close the account; the remaining balance continues to earn interest until full maturity at 21 years. Full premature closure is only allowed for marriage (after age 18) or specific compassionate grounds like the account holder's death or a life-threatening illness.
- Is SSY better than a mutual fund SIP for my daughter's future?
- SSY and equity mutual fund SIPs serve different risk profiles. SSY offers a government-guaranteed 8.2% p.a. return with EEE tax status — zero credit risk, zero market risk. An equity SIP may deliver 12–15% CAGR historically but comes with market volatility, capital gains tax (LTCG at 12.5% above ₹1.25 lakh gains from FY 2024-25), and no capital protection. For a goal like a daughter's education or marriage that cannot be deferred, financial planners typically recommend a core SSY allocation (up to ₹1.5 lakh p.a.) for stability, supplemented by equity SIPs for additional corpus. Use the SSY Calculator alongside an SIP calculator to model both scenarios before deciding on your allocation.
