What is an SSY calculator?
A Sukanya Samriddhi Yojana (SSY) calculator estimates the maturity amount for a girl child's account under the government small-savings scheme. You make annual deposits for 15 years; the account continues until the 21-year horizon at the notified rate.
SSY offers EEE tax benefits and typically carries a higher rate than PPF. The current notified rate is 8.2% p.a., reviewed quarterly like other post-office schemes.
How can an SSY calculator help you?
Parents opening an account before the girl turns 10 often want a rough corpus number for education or marriage planning—without spreadsheet work.
- See total investment (15 × yearly deposit), estimated interest, and maturity value at the fixed 8.2% rate.
- Check the maturity calendar year from your chosen start period (start year + 21).
- Contrast SSY returns with the PPF calculator for another family member.
How does this SSY calculator work?
The Sukanya Samriddhi calculator uses compound interest on your yearly deposit at the prevailing 8.2% p.a. rate. Total investment is always 15 times your yearly contribution. Maturity year is your start period plus 21 years. The girl's age field is for context only—it does not change the maturity amount in this model.
A = P × (1 + r/n)^(n×t)
Where –
| A | Maturity amount |
|---|---|
| P | Principal amount (yearly deposit) |
| r | Rate of interest (8.2% p.a.) |
| n | Number of times interest compounds in a year |
| t | Number of years (21-year SSY horizon) |
Total investment = 15 × P. Total interest = A − (15 × P). Maturity year = start period + 21.
Worked example
Invest ₹10,000 each year for 15 years at the built-in 8.2% assumption. Total deposits equal ₹1,50,000. The calculator returns a maturity value of about ₹4,61,839—roughly ₹3,11,839 in tax-free interest under current rules.
At the maximum ₹1,50,000 per year, total investment is ₹22,50,000 and maturity is about ₹69,27,578 at the same rate.
How to use this SSY calculator
Set yearly investment, the girl's age, and the account start period (opening year). Results show total investment, total interest, maturity year, and maturity value. The interest rate is fixed at 8.2% p.a., matching the latest notified SSY rate.
For general long-term savings without the girl-child eligibility rules, use the PPF calculator.
What this calculator does not include
Partial withdrawal at age 18 (up to 50% of balance), account closure rules, quarterly rate revisions, and year-by-year balance schedules are not modeled. One constant 8.2% rate and the closed-form maturity formula are assumed throughout.
Frequently asked questions
Who can open an SSY account?
A parent or legal guardian can open an account for a girl child below 10 years of age. Only one SSY account is permitted per girl child.
How is the maturity year calculated?
Maturity year equals your start period plus 21 years—the same rule used in this calculator. Deposits are counted for 15 years; the formula assumes the full 21-year SSY horizon at 8.2% p.a.
Does the girl's age change the maturity amount?
In this calculator, no. Yearly investment alone drives total investment and maturity value. Age is shown for planning context; compare eligibility rules on official scheme documents before opening an account.
Is SSY better than PPF?
SSY often offers a higher notified rate and the same EEE tax treatment, but it is limited to eligible girl children. PPF is open to all Indian residents. Compare both with this site's calculators using the same deposit amount.
