Sukanya Samriddhi Calculator
What a Sukanya Samriddhi account matures at, including the six years after deposits stop, and what its tax-free interest is worth against a taxable deposit.
What the Sukanya Samriddhi calculator does
A Sukanya Samriddhi calculator shows what the scheme matures at. Deposits are accepted for fifteen years but the account runs for twenty-one, so the balance compounds untouched for the last six — which produces more than a third of the final amount. It is exempt at all three stages, and the new tax regime removes only the Section 80C deduction.
Your inputs
An account may only be opened for a girl under 10.
Between ₹250 and ₹1,50,000 in a financial year.
When you pay it in
Interest is worked out on the lowest balance between the 5th and month end, so a deposit landing on the 6th earns nothing that month.
Declared by the government and reset every quarter, so it will not hold at one figure for twenty-one years.
Which tax regime are you on?
No Section 80C deduction here — but the interest and the maturity stay tax-free regardless.

37.68% of the maturity comes from years you pay nothing
Deposits run for 15 years but the account runs for 21. For the last six nothing goes in and the whole balance simply compounds — and because it is the largest the account will ever hold, those six years earn ₹27,06,130, more than you deposited in total.

Opening earlier does not raise that figure — the term runs twenty-one years from opening whenever you start, so the maturity amount is the same. What changes is her age when it arrives: opened at birth it pays out at 21, opened at nine it pays out at 30. Since the account also closes on marriage after eighteen, and half the balance may be withdrawn for higher education from eighteen, a late start risks ending the account before the six years that produce most of the growth have run.

You are paying at the best moment
The same rule as PPF: interest is worked out on the lowest balance between the 5th and the last day of each month, so a deposit landing on the 6th earns nothing that month. Over twenty-one years the same ₹1,50,000 a year is worth this much depending only on when it goes in.

What a taxable deposit would have to pay
The interest here is never taxed. A bank deposit’s is taxed every year, which takes the tax out of the compounding rather than off the total — so over twenty-one years the gap is large.

The deposit is assumed to pay the same 8.20% on the same schedule, so the only difference between the two is that its interest is taxed as it is credited. It is not a claim that a bank pays what this scheme pays.

The new regime takes the deduction and nothing else
Section 80C does not apply under the new regime, so a deposit made from there earns no deduction. The interest stays exempt under Section 10(11A) and the maturity stays tax-free — neither depends on your regime. The account remains exempt at all three stages in substance; only the relief on the way in is at stake.

What this assumes
- One rate for twenty-one years. The rate is declared quarterly by the government and has moved considerably over the life of the scheme. No projection at a single figure will match what the account earns.
- The same deposit every year, for all fifteen. The ₹1.5 lakh ceiling is not indexed, so its real value falls across the term.
- Nothing is withdrawn along the way. Up to half the balance may be taken after she turns eighteen for higher education, and the account may close on her marriage after eighteen. Either would end the six-year tail early, which is where most of the growth is.
- One account per girl and generally two per family. Falling below the ₹250 minimum puts the account in default until the shortfall and a penalty are paid.

How the Sukanya Samriddhi calculation works
Deposits for 15 years, interest for 21 — the last six compound with nothing added
Deposits are accepted for fifteen years from opening and the account matures at twenty-one, so the final six years compound the largest balance the account ever holds with nothing paid in. That tail alone is worth more than a third of the maturity figure, which is why opening early matters more than depositing more. Interest accrues on the lowest balance between the 5th and the last day of each month — the same small savings rule as PPF, read from the same module — and is credited once a year. The deposit qualifies under Section 80C within the ceiling shared with EPF, PPF, insurance and ELSS; the interest is exempt under Section 10(11A) and the maturity is exempt, so the new regime removes the deduction and nothing else.
Frequently asked questions
How long do I pay into a Sukanya Samriddhi account?
Fifteen years from the date the account is opened. The account itself matures twenty-one years from opening, so for the last six years nothing goes in and the whole balance simply compounds. Those six years are worth more than a third of the maturity amount, because they compound the largest balance the account ever holds.
Who can open a Sukanya Samriddhi account?
A parent or guardian, for a girl child under the age of ten. Each girl may have one account, and a family may generally hold two — with an exception where a second birth produces twins or triplets.
Is Sukanya Samriddhi taxable?
No. It is exempt at all three stages: the deposit qualifies under Section 80C, the interest is exempt under Section 10(11A), and the maturity is tax-free. Only the Section 80C deduction depends on your regime — under the new regime it is unavailable, while the interest and maturity remain exempt.
When does the account mature?
Twenty-one years from opening, or on the girl's marriage after she turns eighteen, whichever comes first. A partial withdrawal of up to half the balance is permitted after she turns eighteen, for higher education.
How much can I deposit each year?
Between ₹250 and ₹1.5 lakh in a financial year. Falling below the minimum puts the account in default until the shortfall and a small penalty are paid, and anything above the maximum is not accepted.
Does the date I deposit matter?
Yes, for the same reason it does in PPF. Interest is calculated on the lowest balance between the 5th and the last day of each month, so a deposit made on the 6th earns nothing that month. Paying the year's amount on 1 April rather than in late March is worth a substantial sum over twenty-one years.
