How the Sukanya Samriddhi Yojana Calculator Works
Sukanya Samriddhi Yojana (SSY) is a government savings scheme for a girl child. You deposit money every year for 15 years, the balance earns annual compound interest, and the account matures 21 years after it is opened. This calculator turns your yearly deposit and the interest rate into the maturity amount, the total you invested, and the interest you earned.
The Formula
SSY uses annual compounding. Each yearly deposit is added, then interest is credited at the end of the year:
For each year (1 to 15): balance = (balance + yearly deposit) × (1 + r) After year 15: balance keeps compounding for 6 more years until maturity at year 21.
Where r is the annual interest rate as a decimal (for 8.2%, r = 0.082).
Worked Example
Suppose you deposit INR 50,000 per year at an interest rate of 8.2%:
- After the 15-year deposit period, the balance is about INR 14.92 lakh.
- With no further deposits, it compounds for 6 more years to maturity.
- Maturity value at 21 years ≈ INR 23.94 lakh, on a total investment of INR 7,50,000.
The growth comes from compounding: interest is earned on previous interest, year after year.
Maximising Your SSY Maturity
A few choices have a large impact on the final amount:
| Yearly deposit | Total invested (15 yrs) | Approx. maturity at 21 yrs (8.2%) |
|---|---|---|
| INR 50,000 | INR 7,50,000 | ≈ INR 23.9 lakh |
| INR 1,00,000 | INR 15,00,000 | ≈ INR 47.9 lakh |
| INR 1,50,000 | INR 22,50,000 | ≈ INR 71.8 lakh |
Depositing early in the financial year (before the interest is calculated) and contributing the maximum INR 1,50,000 each year both increase the maturity value. Because the government can revise the rate each quarter, re-run the calculator with the latest rate to keep your projection accurate.
Why SSY Is Popular
SSY offers one of the highest fixed rates among small-savings schemes, full tax exemption (EEE status), and a sovereign guarantee. It is designed to build a corpus for a daughter’s education or marriage, which is why parents often start an account as early as possible to give compounding the maximum time to work.
Frequently asked questions
How is the Sukanya Samriddhi Yojana maturity amount calculated?+
You deposit a fixed amount each year for 15 years. Each deposit earns annual compound interest, and after the 15-year deposit period the balance keeps compounding for 6 more years until the account matures at 21 years. The calculator applies the formula year by year using the rate you enter.
How long do I deposit money in SSY and when does it mature?+
You make deposits for 15 years from the date the account is opened. No further deposits are needed after that, but the balance continues to earn interest until the account matures 21 years after opening (or earlier on the girl's marriage after age 18).
What is the minimum and maximum I can deposit in SSY each year?+
The minimum deposit is INR 250 and the maximum is INR 1,50,000 per financial year. You can deposit in one lump sum or in instalments, as long as the yearly total stays within these limits.
What interest rate does Sukanya Samriddhi Yojana pay?+
SSY pays a government-set rate that is reviewed every quarter; it was 8.2% per year at the time of writing. Because the rate can change, the calculator lets you enter the rate so your projection reflects the figure you expect.
Is the interest on SSY taxable?+
SSY has EEE (exempt-exempt-exempt) status: the deposit qualifies for a deduction under Section 80C, and the interest and maturity amount are both tax-free. This calculator shows the gross maturity value, which equals the tax-free amount you receive.
