Year-by-year table and chart

Years 1 to 15 are deposit years; after that the balance only grows. Interest is added at the end of each financial year (31 March).
What if the interest rate changes?
| Rate for the whole time | Maturity | Interest |

Each line keeps one rate for all 21 years. The real rate is reset every quarter, so your result will land somewhere in between.

Sukanya Samriddhi works out interest each month on the lowest balance between the 5th and the last day of the month, adds those monthly amounts up, and credits them once a year at the end of the financial year. You pay in for the first 15 years; for the last 6 years there are no deposits, but the whole balance keeps earning interest until the account matures 21 years after you open it.
The formula
each month's interest = lowest balance from the 5th to month end × rate ÷ 12
yearly interest = sum of the 12 months, added on 31 March
same deposit P every year by 5 April:
balance at 15 years = P × ((1 + r)15 − 1) ÷ r × (1 + r)
maturity at 21 years = balance at 15 years × (1 + r)6
Here r is the yearly rate as a decimal (8.2% = 0.082). A deposit made by the 5th counts for that whole month; one made after the 5th starts earning the next month. So ₹12,500 paid by the 5th of every month earns interest for 12 + 11 + … + 1 = 78 month-shares in its first year, the same as ₹81,250 sitting there all year.
Worked example
₹1,50,000 a year paid by 5 April, for a girl aged 1, at 8.2%. In year 1 the interest is ₹1,50,000 × 8.2% = ₹12,300. After 15 years: 1.08215 = 3.2614364, so (3.2614364 − 1) ÷ 0.082 = 27.5784925, × 1.082 = 29.8399288, and ₹1,50,000 × 29.8399288 = ₹44,75,989 when deposits stop and she is 16. Then 6 years with no deposits: 1.0826 = 1.6045881, and ₹44,75,989 × 1.6045881 = ₹71,82,119 at maturity, when she is 22. You put in ₹22,50,000, so ₹49,32,119 is tax-free interest.
Paying the same yearly total as ₹12,500 by the 5th of each month gives ₹69,32,648, about ₹2.49 lakh less. Paying after the 5th each month gives ₹68,87,289.
Sukanya Samriddhi rules at a glance
| Rule | What it means |
|---|---|
| Who | A girl below 10 years old, opened by a parent or guardian at a post office or bank (one account per girl, up to two girls in a family, more for twins or triplets) |
| Deposit | ₹250 to ₹1,50,000 each financial year, in one go or in parts, for 15 years from opening |
| Missed deposit | The account goes into default; revive it by paying the ₹250 minimum plus a ₹50 fine for each year missed |
| Interest | Set every quarter by the government, on the lowest balance between the 5th and month end, added once a year |
| Maturity | 21 years from opening; interest keeps being added after deposits stop |
| Partial withdrawal | After she turns 18 or passes Class 10: up to 50% of the balance at the end of the previous financial year, for education, in one go or up to 5 yearly instalments |
| Early closure | For her marriage once she is 18; also on her death, or on compassionate grounds (such as serious illness) after 5 years |
| Tax | EEE: deposits qualify for 80C (old regime), interest and maturity are tax-free |
Tax: old and new regime
Under the old regime, SSY deposits count towards the Section 80C deduction of up to ₹1,50,000 a year, shared with EPF, PPF, ELSS, life insurance premiums and others. The new regime has no 80C deduction, but SSY interest and the maturity amount stay tax-free under both. At a 30% slab plus 4% cess, a ₹1,50,000 deposit saves ₹46,800 in tax that year, and a taxable deposit would need about 11.92% to match SSY's 8.2% after tax.
SSY or PPF?
Both are tax-free and use the same "lowest balance after the 5th" rule. SSY usually pays a higher rate (8.2% against PPF's 7.1% now) and runs 21 years with only 15 years of deposits, but it is only for a daughter under 10 and the money is meant for her education and marriage. PPF is open to anyone and can be extended. Many families use both, within the shared ₹1,50,000 80C limit.
This calculator treats each account year as a financial year (April to March), takes withdrawals at the start of the year and uses one interest rate for the whole time. The real rate is set by the government every quarter, so treat the result as an estimate. Ages are her age at the end of each account year. Rules not yet confirmed on the official India Post or National Savings Institute pages, so please check the current rate.
