Frequently asked questions
How does the Sukanya Samriddhi tool compute the maturity value?
This tool uses annual compounding over a 21-year account life. In each of the first 15 years it adds the yearly deposit at the start of the year and then multiplies the balance by one plus the rate. In years 16 to 21 no deposit is added and the balance keeps compounding. The final balance is the maturity amount, and total invested is the yearly deposit times 15.
Which interest rate and year label does it carry?
The rate field starts at 8.2% a year, and the code does not attach a year or quarter label to it. Savings-scheme rates are announced quarterly or periodically and Indian tax rules change in nearly every Union Budget; the tool’s starting value is not updated automatically. For the rate that actually applies, rely on the scheme notification, the Income Tax Department or a qualified chartered accountant.
What age does the tool accept for the girl child?
The tool shows an error when the age entered is above 10 and accepts every age from 0 to 10, so an entry of exactly 10 still calculates. Age is only used for two output lines: the age at which the account matures (age plus 21) and the age at which deposits stop (age plus 15). It does not change the amount.
What is the deposit limit, and is there a minimum?
A yearly deposit above ₹1,50,000 returns an error, and a zero deposit (which is also what a cleared box becomes) or a negative deposit returns a maturity amount of ₹0. The tool does not enforce a minimum deposit, so very small amounts calculate as normal. It also treats the deposit as one payment at the start of each year, ignoring how many instalments you might make.
Why is the multiplier so high compared with a 15-year scheme?
Because the balance continues to compound for six more years after the last deposit. At 8.2% with ₹1,50,000 a year, the tool shows total invested of ₹22,50,000 and a maturity amount of ₹71,82,119, a multiplier of 3.19×. A large share of that comes from the years in which nothing new goes in.
What happens with a rate of 0%?
A rate of 0 is honoured. The maturity amount equals the total invested, interest earned is ₹0 and the multiplier is 1.00×. The rate box starts at 8.2%; clearing it counts as 0, which gives that result, and a negative rate is also read as 0%. A zero girl age is valid and is also the starting value.
What does the calculation not cover?
It does not model partial withdrawals for education or marriage, a missed deposit, a change in the rate during the 21 years, the way interest is actually calculated month by month, closure rules or tax. The result is a constant-rate illustration, not a statement of what an account will show.
Sukanya Samriddhi maturity: 15 years of deposits and six years of growth
Two phases in one account
The tool treats the account as a deposit phase followed by a growth phase. For fifteen years the yearly amount is added at the start of the year and the balance compounds at the chosen rate. For the remaining six years the balance simply compounds. Maturity is therefore a mix of fifteen deposits that each grow for a different number of years, with the first one compounding for all twenty-one.
Worked examples: a two-year-old’s plan and a five-year-old’s
For a girl aged 2 with the starting inputs of ₹1,50,000 a year at 8.2%, the tool returns ₹71,82,119 at maturity on ₹22,50,000 invested, interest of ₹49,32,119, a 3.19× multiplier, maturity at age 23 and deposits stopping at age 17. For a girl aged 5 with ₹50,000 a year at 7.6%, it returns ₹21,97,690 on ₹7,50,000 invested, interest of ₹14,47,690, a 2.93× multiplier, maturity at age 26 and deposits ending at age 20. Both results were confirmed against a closed-form sum of the fifteen deposits.
Three runs compared
The table puts a zero-rate run beside the two examples above so that the growth effect of the rate can be separated from the deposits themselves. The zero-rate row returns exactly what went in.
| Inputs | Total invested | Maturity amount | Interest earned | Matures at age |
|---|---|---|---|---|
| ₹1,50,000 a year, age 2, 8.2% | ₹22,50,000 | ₹71,82,119 | ₹49,32,119 | 23 |
| ₹50,000 a year, age 5, 7.6% | ₹7,50,000 | ₹21,97,690 | ₹14,47,690 | 26 |
| ₹10,000 a year, age 0, 0% | ₹1,50,000 | ₹1,50,000 | ₹0 | 21 |
Rules the tool applies on its own
An age above 10 returns an error message, a deposit above ₹1,50,000 returns an error message, and a zero deposit, which is also what a cleared box becomes, returns ₹0. The 15-year deposit window, the 21-year life and the 8.2% starting rate are the figures built into this tool. No minimum deposit is enforced, so very small amounts calculate normally.
Reading the result carefully
Real accounts have their rate revised from time to time and compute interest monthly on a lowest balance, so the single constant rate here is a simplification. Withdrawals, closure and tax are outside the tool. Use the output to see how deposit size, rate and age change the numbers, and confirm anything that matters with the scheme notification or a qualified chartered accountant.
