What the SSY Calculator does
The Sukanya Samriddhi Yojana (SSY) is a small-savings scheme run by the Government of India under the Beti Bachao Beti Padhao campaign, meant to build a long-term corpus for a girl child's higher education or marriage. This calculator projects what that account is worth at maturity: enter the amount you plan to deposit each financial year and the interest rate you want to assume, and it returns the total you will have deposited, the interest earned and the amount payable when the account matures 21 years after it was opened.
Because SSY only exists as a rupee-denominated Indian scheme, the calculator is fixed to ₹ and applies the statutory rules directly: a 15-year deposit window, a 21-year maturity, and the ₹250–₹1,50,000 per-year deposit band.
How the SSY maturity value is calculated
The scheme lets you deposit for 15 years, but the account keeps compounding for a full 21 years. So your first deposit earns interest for 21 years, while your fifteenth (and last) deposit earns interest for 7 years. After year 15 no new money goes in — the balance simply compounds untouched for the remaining 6 years. Assuming a constant annual deposit A at the start of each financial year and an annual rate r, the maturity value is:
M = A × Σ (1 + r)22 − i for i = 1 … 15
In plain terms, each of the 15 deposits is grown forward to the year-21 maturity and the fifteen results are added together. Interest is credited once a year, at each financial-year end, and rounded to the nearest rupee as the Gazette rules require — which is why the exact figure can differ by a few rupees from the un-rounded formula.
Worked example
Depositing the maximum ₹1,50,000 every year for 15 years at 8.2% p.a. produces roughly a ₹71.8 lakh corpus — the figure the official scheme illustration quotes. These numbers are produced by the same engine that runs the calculator above, so they always match the tool:
| Input / result | Value |
|---|---|
| Annual deposit (15 years) | ₹1,50,000.00 / year |
| Assumed interest rate | 8.2% p.a. |
| Deposit period | 15 years |
| Maturity period | 21 years |
| Total deposited | ₹22,50,000.00 |
| Total interest earned | ₹49,32,127.00 |
| Maturity amount (year 21) | ₹71,82,127.00 |
You deposit ₹22.5 lakh in total (15 × ₹1.5 lakh), and the scheme roughly triples it over 21 years. Halving the yearly deposit roughly halves the maturity value, so the outcome scales almost linearly with what you put in — the table below shows this at four common deposit levels, all at the current 8.2% rate:
| Annual deposit | Total deposited | Total interest | Maturity amount |
|---|---|---|---|
| ₹10,000.00 / year | ₹1,50,000.00 | ₹3,28,808.00 | ₹4,78,808.00 |
| ₹50,000.00 / year | ₹7,50,000.00 | ₹16,44,036.00 | ₹23,94,036.00 |
| ₹1,00,000.00 / year | ₹15,00,000.00 | ₹32,88,077.00 | ₹47,88,077.00 |
| ₹1,50,000.00 / year | ₹22,50,000.00 | ₹49,32,127.00 | ₹71,82,127.00 |
SSY vs PPF vs a fixed deposit
SSY sits alongside two other popular safe-money options. If you also want to model a general tax-free corpus, use the PPF calculator; for a plain bank deposit over a chosen term, the FD calculator works out the same annual-compounding math. To compare against a monthly mutual-fund investment plan, the SIP calculator projects market-linked growth instead of a fixed statutory rate.
| Feature | SSY | PPF | Fixed deposit |
|---|---|---|---|
| Who can open | Girl child only (before age 10) | Any resident individual | Anyone |
| Deposit period | 15 years | 15 years (extendable in blocks of 5) | Chosen term (7 days–10 years) |
| Maturity / lock-in | 21 years from opening | 15 years | End of chosen term |
| Annual deposit limit | ₹250 – ₹1,50,000 | ₹500 – ₹1,50,000 | No statutory cap |
| Interest (2026 guide) | ~8.2% p.a. | ~7.1% p.a. | Bank-set, ~6–7.5% p.a. |
| Tax treatment | EEE (fully tax-free) | EEE (fully tax-free) | Interest taxable (unless 5-yr tax-saver 80C) |
| Rate guaranteed | Reset quarterly by govt | Reset quarterly by govt | Fixed for the term |
Eligibility and key scheme rules
- The account is opened by a parent or legal guardian for a girl child below 10 years of age.
- A minimum of ₹250 and a maximum of ₹1,50,000 can be deposited each financial year.
- Deposits are made for 15 years; the account matures 21 years after opening.
- Deposits qualify for a Section 80C deduction, and both the interest and the maturity amount are tax-free (EEE).
- Up to two accounts per family (a third is allowed for twins/triplets in a later birth).
- A 50% partial withdrawal is allowed for higher education once the girl turns 18 or clears 10th standard.
Assumptions and limitations
This projection is a planning estimate, not a guaranteed payout. Keep these in mind:
- It assumes a single, constant deposit made at the start of every financial year. The scheme actually allows a different amount each year, and the exact day a deposit lands in the month affects the interest under the strict "lowest balance between the 5th and month-end" rule — so published calculators can show anywhere from about ₹69 to ₹72 lakh for the same inputs.
- It holds one interest rate constant for the whole 21-year term. In reality the government re-fixes the SSY rate every quarter, so your actual result will differ.
- It does not model the ₹50/year default penalty for a missed deposit, partial withdrawals, or premature account closure.
- The rate and deposit limits are specific to the current financial year — re-check them against the latest government notification before relying on the figure.
Frequently asked questions
What is the Sukanya Samriddhi Yojana (SSY)?+
SSY is a government-backed savings scheme launched under the Beti Bachao Beti Padhao initiative, exclusively for the benefit of a girl child. A parent or legal guardian opens the account any time before the girl turns 10, deposits are made for 15 years, and the account matures 21 years after it was opened.
How much can I deposit in an SSY account each year?+
You can deposit a minimum of ₹250 and a maximum of ₹1,50,000 in a single financial year, in one lump sum or in instalments. This calculator caps the yearly deposit at ₹1.5 lakh because amounts above that ceiling are not accepted into the account.
What is the current SSY interest rate?+
For the July-September 2026 quarter the government has kept the Sukanya Samriddhi Yojana rate at 8.2% per annum, unchanged since January 2024 — the highest rate among small savings schemes. The rate is reviewed and can change every quarter, so this calculator lets you test different assumptions.
How is the SSY maturity amount calculated?+
This calculator assumes you deposit the same amount at the start of every financial year for 15 years. Interest compounds annually and is credited at each financial-year end. After the 15th deposit, no more money goes in, but the balance keeps earning interest for another 6 years until the account matures at year 21 — so your last deposit still grows for 6 more years.
Why does the account mature after 21 years but deposits stop after 15?+
This is a deliberate design of the scheme: it front-loads your contributions into the first 15 years, then lets the accumulated balance compound untouched for a further 6 years, boosting the maturity value without requiring you to keep depositing money for the full 21-year term.
Is Sukanya Samriddhi Yojana interest and maturity amount tax-free?+
Yes. SSY carries "EEE" (exempt-exempt-exempt) tax status: yearly deposits qualify for a deduction of up to ₹1.5 lakh under Section 80C, the interest that accrues is tax-free, and the maturity amount is fully exempt when withdrawn.
Can I withdraw money from an SSY account before maturity?+
A partial withdrawal of up to 50% of the balance at the end of the previous financial year is allowed once the girl turns 18 or passes her 10th standard exam, typically for higher education expenses. Premature closure of the full account is otherwise permitted only in limited circumstances such as the death of the account holder or a change in her citizenship or residency status.
What happens if I miss a yearly deposit?+
The account is not closed, but it is treated as irregular until you pay the minimum ₹250 for that year plus a ₹50 default penalty per missed year to regularise it. This calculator assumes every year's deposit is made on schedule, so a missed year in practice will produce a lower maturity value than shown here.
How many SSY accounts can I open, and for how many daughters?+
A family can open only one SSY account per girl child, and generally no more than two accounts in total (an exception allows a third account for twins/triplets born in a second delivery). Every account must be opened before the girl turns 10 years old.
Is SSY better than a Public Provident Fund (PPF) account?+
Both are government-backed, tax-free EEE schemes, but they serve different purposes and have different structures. SSY is restricted to a girl child, runs on a fixed 15-years-deposit/21-years-maturity timeline, and typically carries a higher interest rate. PPF is open to anyone, has a shorter 15-year tenure that can be extended, and offers partial-withdrawal and loan-against-balance features that SSY does not. Many families use SSY specifically for a daughter's education or marriage goal alongside a separate PPF for general retirement savings.
Does this calculator account for changes in the interest rate over 21 years?+
No — it projects the maturity value using a single interest rate held constant for the entire term, since that is the only way to give a deterministic estimate. In reality, the Sukanya Samriddhi Yojana rate is reset by the government every quarter, so your actual maturity amount will differ from this projection based on the rates that apply in each future year.
Can I increase or decrease my yearly deposit amount?+
Yes, the scheme allows any amount between ₹250 and ₹1,50,000 each year and it can vary year to year. This calculator assumes a single constant deposit amount for simplicity and comparability with the standard published illustrations; use the highest amount you plan to deposit consistently for the most realistic estimate.
