Sukanya Samriddhi Yojana Calculator
Estimate what a Sukanya Samriddhi Yojana account will be worth at maturity — 21 years after opening — based on your annual contribution.
An SSY account can only be opened for a girl under 10 years old.
The financial year the account was (or will be) opened — used to work out the maturity year below.
Statutory range: ₹250 – ₹1,50,000 per financial year.
Government-notified, revised quarterly — pre-filled with the current rate.
Contributions run for 15 years, from 2026 to 2040. The account then matures in 2047 — when your daughter turns 22 — with no further deposits needed after year 15, just continued compounding.

SSY tips
- Deposit early in the financial year (before 5 April) to maximise that year's interest.
- You can open SSY accounts for up to two girl children in a family (exceptions apply for twins/triplets).
- Compare SSY's rate against PPF's — SSY typically runs higher, but is restricted to a girl child beneficiary.
How it's calculated
SSY only accepts contributions for the first 15 years from account opening; the balance then compounds untouched for another 6 years until the account matures 21 years after opening. This calculator models both stages: an annuity-due for the 15 contribution years, then pure compounding for the remaining 6.
Balance at year 15 = Annual contribution × [(1 + r)¹⁵ − 1] / r × (1 + r)
Maturity value (year 21) = Balance at year 15 × (1 + r)⁶
Example
Contributing the maximum ₹1,50,000 every year for 15 years at 8.2% grows to roughly ₹71,82,119 by maturity (year 21) — about ₹49,32,119 in tax-free interest on ₹22,50,000 contributed.
About Sukanya Samriddhi Yojana
SSY is a government-backed scheme designed specifically to build a corpus for a girl child's education or marriage. It offers one of the highest interest rates among small savings schemes, along with the same EEE tax status as PPF — contributions, interest and maturity value are all tax-free.
How it works
A parent or guardian opens the account for a girl child under 10, and can contribute ₹250 to ₹1,50,000 per financial year for the first 15 years. After that, no further deposits are accepted, but the balance keeps earning interest until the account matures 21 years after opening — or when the girl marries after turning 18, whichever comes first.
How to use it
- Set the annual amount you plan to contribute (₹250 minimum, ₹1,50,000 maximum per financial year, for 15 years).
- The interest rate is pre-filled with the current government-notified rate.
- The 15-year contribution window and 21-year maturity are fixed by law, so there's no tenure to set.
Strategies
As with PPF, depositing early in the financial year (before 5 April) maximises that year's interest, since SSY interest is based on the lowest monthly balance. Because the account spans 21 years and the rate is revised quarterly, treat this projection as an estimate — the actual maturity value will track whatever rates apply over the real 21-year period.
Important caveats
- This calculator assumes one deposit per year, timed for maximum interest — depositing later in the year, or in instalments, earns somewhat less than shown.
- Partial withdrawal is allowed once the girl turns 18 (for higher education) — not modelled here, which assumes the account runs untouched to maturity.
- The interest rate is fixed for the projection but is actually revised by the government every quarter over the real 21-year account life.
Why it works
The first 15 years follow the same future-value-of-an-annuity maths as a SIP or PPF — a fixed deposit every year, compounding annually. The remaining 6 years have no new deposits, so the balance simply compounds on itself, which is why the maturity value is the year-15 balance multiplied by (1 + rate) six more times.
Benefits
- One of the highest interest rates among government-backed small savings schemes.
- EEE tax status — contributions, interest and maturity are all tax-free.
- Purpose-built for a girl child's education or marriage, with the discipline of a long, fixed contribution window.
Frequently asked questions
Why does SSY mature after 21 years but contributions stop at 15?
By design, SSY only requires you to contribute for the first 15 years from account opening. The balance then keeps earning interest, untouched, for another 6 years until the account matures 21 years after it was opened (or when the girl marries after turning 18, if earlier).
Who is eligible to open an SSY account?
A parent or legal guardian can open an SSY account for a girl child who is under 10 years old at the time of opening. A family can open accounts for up to two girl children (with exceptions for twins/triplets).
Is SSY interest taxable?
No. Like PPF, SSY has EEE (exempt-exempt-exempt) tax status: contributions qualify for a Section 80C deduction, and both the interest earned and the maturity amount are tax-free.
