Sukanya Samriddhi Yojana Calculator
See what your daughter's account grows to, year by year
Where the growth actually comes from
- Deposits run for 15 years. The account matures at 21 years from opening. Interest keeps accruing in between.
- The rate is fixed at the current 8.2% and held constant for all 21 years. In reality the government revises it every quarter, so your actual maturity amount will differ.
- Deposits are treated as made at the start of each year, with interest compounded annually.
- Actual interest is calculated on the lowest balance between the 5th and the end of each month, and credited at the end of the financial year. Depositing early in the year earns more than depositing late.
- Minimum ₹250 and maximum ₹1,50,000 in a financial year.
What This Calculator Shows You That Others Do Not
Most Sukanya Samriddhi calculators give you one number and stop. This one shows you where that number comes from, and the answer surprises most parents.
You deposit for 15 years. The account matures at 21 years. That leaves six years in the middle where you pay nothing and the balance simply grows.
Those six idle years are not a footnote. At a deposit of ₹1,00,000 a year, you put in ₹15,00,000 over fifteen years and the account matures at ₹47,88,079. Of that growth, around ₹18 lakh arrives after your last deposit, which is more than you paid in altogether.
That is the case for opening the account as early as possible. Every year you delay is a year taken off the end, where compounding is doing the most work.

The Date That Costs People Money
Interest is calculated on the lowest balance between the 5th of a month and the end of that month, and credited once a year at the close of the financial year.
So the day you deposit matters. Money paid in before the 5th of April earns interest for the whole year. The same amount paid in March earns almost nothing for that year.
If you deposit annually, do it in the first week of April. Over fifteen years, that habit alone is worth a noticeable sum.
Two Rules Parents Get Wrong
Grandparents cannot open the account. Only natural parents or a court-appointed legal guardian can, so a grandparent without legal guardianship is not eligible to open it.
Missing the minimum lapses the account. If you do not deposit at least ₹250 in a financial year, the account becomes a default account. You can revive it within the 15 year deposit period by paying the missed minimum for each year plus a penalty of ₹50 per year of default.
When She Turns 18
Two things become possible once your daughter turns 18, and the calculator marks the year for you.
- Partial withdrawal of up to 50% of the balance at the end of the previous financial year, for higher education, once she has turned 18 or passed Class 10. You will need the admission letter and fee receipts.
- Premature closure on marriage, permitted only after she turns 18.
Check the withdrawal year in the calculator against your daughter's current age. If she is five today, she turns 18 in year 13, which falls inside the deposit period rather than after it. For most families that means the education withdrawal becomes available while you are still paying in.
