SSY (Sukanya Samriddhi Yojana) Calculator

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. It combines a sovereign government guarantee, one of the highest interest rates among small savings instruments, and complete EEE tax status - contributions are deductible under Section 80C, the interest is tax-free, and the maturity amount is tax-free. This SSY calculator shows you exactly how your annual deposits compound over the 21-year horizon, with a year-wise breakdown and an optional inflation adjustment, so you can understand the real purchasing power of the maturity corpus.

Enter your yearly deposit and the account start year. The calculator applies your SSY rate and builds the full schedule through the 15 deposit years and the remaining 6 years of passive compounding until maturity - showing your total invested, total interest earned, maturity year, and the final maturity value. It also includes a unique SSY vs PPF comparison panel that most calculators do not offer, so you can see exactly what the SSY rate advantage is worth for your daughter.

What Is Sukanya Samriddhi Yojana (SSY)?

Sukanya Samriddhi Yojana is a small savings scheme launched by the Government of India as part of the Beti Bachao Beti Padhao initiative. It is offered by both banks and post offices. A parent or legal guardian can open an SSY account for a girl child who is under 10 years of age. Only one account can be opened per girl child.

Deposits can be made for 15 years from the date of account opening, with a minimum of Rs.250 per financial year and a maximum of Rs.1.5 lakh per financial year. After the 15 deposit years, the account continues to earn interest for 6 more years without any further deposits, and matures 21 years from the date of opening. The interest rate is set by the government and revised quarterly, with the latest rate at 8.2% p.a.

The SSY Tenure - 15 Deposit Years Plus 6 Years of Passive Growth

The full SSY tenure is 21 years from account opening, but it is not uniform. For the first 15 years, you add a deposit each year, and interest is calculated on that growing balance. From year 16 through year 21, you make no new deposits, but the existing balance keeps earning the SSY interest rate, compounded annually.

This 6-year passive compounding window is a powerful part of the scheme. For example, a balance of around Rs.50 lakh at the end of year 15 earns about 8.2% per year for six more years with no fresh money, adding significantly to the final corpus. This calculator shows this clearly - the last six years of the breakdown table have zero investment but substantial interest.

The SSY Formula and How Compounding Works

SSY interest is calculated on the minimum balance between the 5th and last day of each calendar month, then summed and credited annually at the end of the financial year. For planning purposes, the annual compounding works as follows: in each of the 15 deposit years, interest is added to the opening balance plus your new deposit; in each of the 6 passive years, interest is added to the existing closing balance only.

Example: Rs.1.5 lakh deposited every year for 15 years at 8.2%. Total invested is Rs.22.5 lakh. After the 15 deposit years and 6 passive-growth years, the maturity amount is about Rs.71.8 lakh. The tax-free interest earned is about Rs.49.3 lakh - more than double the amount you invested, entirely free of tax. The 6 years of passive compounding after the 15th deposit account for a significant portion of this gain.

Understanding the Smart Insights in This Calculator

Beyond the headline numbers, this SSY calculator shows a few quick-read insights that turn raw figures into decisions:

• Total Growth: The percentage your deposits grow by over the full 21 years. It shows how much of the maturity is pure interest rather than your own money.
• Corpus Multiplier: How many times your total invested amount your maturity represents. At 8.2%, deposits roughly grow by more than three times, giving an idea of the power of the guaranteed compounding.
• Effective Yield: The true annualised return on your invested capital. Because the 15 deposits are spread over 15 years and then compound for 6 more, this real per-year return differs from the nominal rate and is the most honest number for comparing with other options.
• Deposit Years (of 21): Reminds you that only 15 of the 21 years require your money, while the rest grow on their own.
• Real Return (net of inflation): Appears when you switch on inflation adjustment. It is the true growth of your purchasing power, roughly your SSY rate minus the inflation rate.

SSY vs PPF - Why This Comparison Matters

SSY and PPF are the two most popular guaranteed, tax-free savings schemes in India. Both offer EEE (Exempt, Exempt, Exempt) tax status, are backed by the government, and compound interest annually. The main difference is the interest rate: SSY currently pays 8.2% vs PPF's 7.1%, an advantage of about 1.1 percentage points that compounds dramatically over 21 years.

The SSY vs PPF comparison panel in this calculator shows the two schemes side by side using the same annual deposit and the same 15 + 6 year structure, so it is a fair, apples to apples comparison. For example, at Rs.1.5 lakh per year over 21 years, SSY at 8.2% matures to roughly Rs.71.8 lakh while a PPF at 7.1% matures to about Rs.53.6 lakh - a difference of roughly Rs.18 lakh, purely from the rate advantage. The panel shows these numbers live and, if you set the PPF rate equal to or above the SSY rate, honestly tells you the schemes are now equal.

Choosing SSY over PPF is only valid when it is for a girl child under 10. For a son, or to keep the flexibility, PPF remains the relevant choice. If you have both, the sensible order is to maximise SSY first because of the higher guaranteed rate.

SSY's Critical Rule - Deposit Before 5 April Every Year

SSY interest is calculated on the minimum balance from the 5th to the last day of each calendar month. Depositing before 5 April, which is the start of the financial year, means your full annual deposit earns interest for the entire year. Depositing after 5 April loses the interest for that first month on the new deposit.

Over 15 years of maximum contributions, consistently depositing before 5 April can add roughly Rs.2 to 4 lakh to the final corpus - a difference easily worth a calendar reminder. This calculator assumes your deposit earns interest for the full year, which matches the recommended best practice of depositing early.

SSY vs PPF vs ELSS - Choosing the Right Scheme for a Girl Child

SSY vs PPF: SSY 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 only for girl children under 10 at opening, while PPF is open to any individual. The higher SSY rate makes it the preferred instrument specifically for a daughter's education and marriage corpus, though it 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 carry market risk. SSY's 8.2% is fixed and guaranteed. For parents with a lower risk tolerance, or those who need a predictable corpus for their daughter, SSY is the safer choice. Many parents use both: SSY for the guaranteed base and an ELSS SIP for higher-growth potential.

Partial Withdrawal, Premature Closure, and Maturity Rules

Partial withdrawal at 18: Once the girl turns 18 and the account is at least 5 years old, up to 50% of the balance at the end of the preceding financial year can be withdrawn, typically for higher education. This can be taken as a lump sum or in up to 5 annual instalments.

Closure at marriage: The account can be closed prematurely on the girl's marriage after she turns 18, provided it has been open for at least 5 years. The full balance is paid out tax-free, making SSY a natural education-cum-marriage fund.

Normal maturity: The account matures 21 years from the opening date, and the full balance can then be withdrawn. Premature closure for other reasons is allowed only in specific conditions such as the death of the account holder or guardian, and otherwise pays a lower post-office savings rate.

Tax Treatment and the New Tax Regime

SSY enjoys EEE status: contributions are deductible under Section 80C up to Rs.1.5 lakh per year under the old tax regime, the interest earned each year is tax-free, and the maturity amount is tax-free. This triple exemption is what makes SSY's effective return so attractive for long-term planning.

Under the new tax regime, which is the default from financial year 2024-25, the Section 80C deduction on SSY contributions is not available. However, the interest and maturity remain tax-free regardless of the regime you choose, so SSY still performs strongly as a tax-efficient savings tool in both regimes.

Maximising Your SSY Returns - Timing and Deposit Strategies

The single most impactful habit is to deposit before 5 April each year so the full amount earns interest for all 12 months. Depositing Rs.1.5 lakh in monthly instalments of Rs.12,500 means the May deposit earns interest for only 11 months, June for 10, and so on, reducing the total interest. Over 15 years this timing discipline adds significantly to the final corpus.

The second strategy is to maximise the annual contribution every single year. The SSY limit of Rs.1.5 lakh runs on the financial year (April to March), so set up a recurring transfer in the first week of April to lock in the full amount. If Rs.1.5 lakh is not feasible, commit to at least Rs.250 to keep the account active and increase as income grows.
