What Is a Sukanya Samriddhi Yojana Calculator?
A Sukanya Samriddhi Yojana (SSY) calculator projects what a girl-child savings account grows to at maturity — using your yearly deposit, the 8.2% rate and the scheme's 15-year deposit, 21-year maturity rule.
SSY is a government scheme for a girl child. A parent opens it before the daughter turns 10 and deposits between ₹250 and ₹1.5 lakh a year. It pays one of the highest small-savings rates — 8.2% for FY 2025-26 — compounded yearly, and the calculator turns your plan into a tax-free maturity figure.
You deposit for 15 years, but it matures at 21. This is the rule most people miss: deposits stop after 15 years, yet the balance keeps compounding for another 6 years until the account matures 21 years after opening. Those final deposit-free years add a large chunk of interest, which this calculator shows separately.
Only ₹1.5 lakh a year earns interest. A deposit below ₹250 can default the account; anything above ₹1.5 lakh earns nothing and gives no tax benefit. The calculator computes on the eligible amount and flags any excess.
It is one of India's most tax-efficient options (EEE). The deposit is deductible under Section 80C, the interest is tax-free, and the maturity is tax-free. Beyond the headline figure, the calculator shows the 50% you can withdraw at 18 for her education, models monthly versus yearly deposits, and gives the maturity's worth in today's money after inflation.

How It Works
Calculate Your SSY Maturity in Three Steps
02
Set the rate and her age
The rate defaults to the current 8.2%. Enter the girl's age so the calculator can show when the account matures.
03
Read the maturity amount
See the tax-free maturity at 21 years, the total you deposit, the interest earned, and the balance when deposits stop at year 15.

The Formula
How SSY Maturity Is Worked Out
01
Deposit phase (years 1–15)
Each year: Balance = Balance × (1 + r) + Deposit × (1 + r × t)
r is the annual rate (e.g. 0.082) and t is the timing factor — 1 for a yearly lump early in the year, about 0.54 for monthly deposits. Deposits run for the first 15 years only.
Example: P = ₹1,50,000, r = 8.2%, 15 years → balance ≈ ₹44.8 lakh at year 15
02
Maturity phase (years 16–21)
Maturity = Balance at year 15 × (1 + r)^6
After year 15 no more deposits are made, but the balance keeps compounding for 6 more years until the account matures at 21 years from opening.
Example: ₹44.8 lakh × (1.082)^6 ≈ ₹71.8 lakh at maturity
03
Total interest
Interest = Maturity − Total deposited
The tax-free interest is the maturity value minus the ₹22.5 lakh you deposited over 15 years — most of the corpus is interest, not your own money.
Example: ₹71.8 lakh − ₹22.5 lakh ≈ ₹49.3 lakh interest

Step-by-Step Walkthrough (₹1.5 lakh a year, 8.2%)
Currency note: the example below uses a benchmark scenario priced in Indian Rupee (INR). Values are converted to US Dollar (USD) at the latest exchange rate so you can compare against your own numbers.
Scenario
A parent opening an SSY account for a 5-year-old daughter, depositing $150,000.00 a year at 8.2%.
1
Step 1 · Deposit for 15 years
Putting in $150,000.00 a year for 15 years deposits $2,250,000.00, which compounds to a balance when deposits stop.
Balance at year 15 = $4,475,989.00
2
Step 2 · Compound 6 more years
No more deposits go in, but the balance keeps earning 8.2% for 6 years until the account matures at 21 years.
Maturity = $7,182,119.00
3
Step 3 · Tax-free interest
The gap between maturity and what you deposited is pure tax-free interest.
Interest = $4,932,119.00
The takeaway
A full ₹1.5 lakh a year turns ₹22.5 lakh of deposits into about $7,182,119.00 by maturity — roughly $4,932,119.00 of it tax-free interest. The deposit-free years 16–21 do a surprising amount of the work, which is why starting early matters so much.

Common Mistakes
SSY Mistakes to Avoid
Thinking you deposit for all 21 years
Why it matters
Deposits are only allowed for the first 15 years. People who plan to pay in for 21 years are surprised when the account stops accepting deposits — and may under-fund the early years that compound longest.
Fix
The calculator splits the 15-year deposit phase from the 6-year maturity phase, so you see exactly when to stop paying in.
Missing the ₹250 minimum
Why it matters
If less than ₹250 goes in during a financial year, the account is treated as in default and needs a penalty to revive. Many forget a year and lose interest.
Fix
Deposit at least ₹250 every year for all 15 years. The calculator flags a deposit below the minimum.
Opening too late
Why it matters
An SSY account can only be opened before the girl turns 10. Waiting cuts the years of compounding — and after 10 the option is gone entirely.
Fix
Enter her age; the calculator warns if she is no longer eligible and shows how the maturity changes with an earlier start.
Depositing late in the year
Why it matters
Interest is calculated on the balance from the 5th of the month. Depositing in March instead of April costs almost a year of interest on that contribution.
Fix
Deposit by early April. The calculator's yearly option assumes this; switch to monthly to see the cost of spreading it out.
Going over ₹1.5 lakh a year
Why it matters
Any amount above ₹1.5 lakh earns no interest and gets no 80C benefit — it simply sits idle in the account.
Fix
Keep deposits at or below ₹1.5 lakh. The calculator flags any excess and computes only on the eligible amount.
Pro Tips
Get More From Your SSY
Open as early as you can
The sooner you open it, the more years compound — especially the deposit-free years 16–21. Opening near birth maximises the corpus.
Deposit by 5 April
Pay the year's amount at the start of the financial year so it earns a full 12 months of interest, not a partial year.
Aim for ₹1.5 lakh
The full ₹1.5 lakh both maximises the tax-free corpus and uses your entire Section 80C limit in one safe product.
Use it alongside PPF
SSY pays more (8.2%) but is locked to one daughter. Pair it with PPF for general savings and you cover both goals tax-free.
Plan the 50% withdrawal
You can take half the balance once she turns 18 for education. Factor that into college planning rather than waiting for full maturity.
Who Uses This
Who Uses This SSY Calculator
The Sukanya Samriddhi Yojana Calculator works across every stage of the workflow.
Parents of a young daughter
A parent opening an account for a 3-year-old checks what ₹1.5 lakh a year becomes by the time she turns 21.
Families planning education
Parents work out the balance available at 18 (when 50% can be withdrawn) to see if it covers college fees.
Tax-saving investors
Someone wanting a safe, tax-free home for their ₹1.5 lakh 80C limit compares SSY's 8.2% with PPF's 7.1%.
Grandparents gifting savings
A grandparent contributing each year checks how much a modest ₹50,000 annual deposit grows to by maturity.
Monthly savers
A family that can only set aside money monthly checks how much less that earns than a single April deposit.
Glossary
Key SSY Terms
Every important term you'll encounter in this calculator and the broader topic.

Help & answers
Frequently asked questions
Everything you need to know about how the Sukanya Samriddhi Yojana Calculator works.
01What is a Sukanya Samriddhi Yojana calculator?
An SSY calculator projects what a Sukanya Samriddhi Yojana account grows to at maturity. You enter the yearly deposit, the interest rate and the girl's age; it shows the tax-free maturity amount at 21 years, the total you deposit, and the interest earned.
02What is the SSY interest rate for 2025-26?
The SSY interest rate is 8.2% per annum for FY 2025-26 — among the highest of all small-savings schemes. The government reviews it every quarter, so it can change; this calculator lets you set any rate to model your own assumption.
03How is the SSY maturity amount calculated?
You deposit for the first 15 years; the account then keeps compounding for 6 more years and matures at 21. Interest is compounded yearly at 8.2%. So a year-1 deposit grows for 21 years, while the balance at year 15 earns interest right up to maturity.
04What is the maturity of ₹1.5 lakh per year in SSY?
Depositing ₹1.5 lakh a year at 8.2% grows to about ₹71.8 lakh at maturity — ₹22.5 lakh deposited over 15 years plus roughly ₹49.3 lakh of tax-free interest. Spreading it monthly instead gives about ₹69.3 lakh.
05How many years do I deposit in SSY?
15 years from opening. After that you make no more deposits, but the balance keeps earning interest for another 6 years until the account matures at 21 years from the opening date.
06What is the minimum and maximum SSY deposit?
₹250 minimum and ₹1.5 lakh maximum in a financial year. A deposit below ₹250 can put the account in default; anything above ₹1.5 lakh earns no interest and gets no Section 80C benefit, so the calculator computes only on ₹1.5 lakh.
07Is Sukanya Samriddhi Yojana tax-free?
Yes — SSY has EEE (Exempt-Exempt-Exempt) status. The deposit qualifies for a deduction up to ₹1.5 lakh under Section 80C, the interest is tax-free, and the maturity amount is fully tax-free. It is one of the most tax-efficient options in India.
08Who can open a Sukanya Samriddhi account?
A parent or legal guardian can open it for a girl child under 10 years of age, with one account per girl and up to two girls per family (three if the second birth is twins). It cannot be opened once she turns 10.
09Can I withdraw from SSY before maturity?
Partly. You can withdraw up to 50% of the previous year's balance once the girl turns 18, for her higher education or marriage. The full amount is available only at maturity — 21 years from opening, or on her marriage after 18.
10How much can I withdraw from SSY for education at 18?
Up to 50% of the balance at the end of the previous financial year, once she turns 18 and has passed Class 10. The calculator shows this education-withdrawal figure from the balance she will have built by then.
11What is the SSY maturity worth after inflation?
At 8.2% against about 6% inflation, SSY gives a real return of roughly 2%. The calculator shows the maturity in today's money — a ₹71.8 lakh corpus is worth far less in 21 years, though still tax-free.
12SSY vs PPF — which is better?
SSY pays a higher rate (8.2% vs PPF's 7.1%) and both are EEE and 80C-eligible, but SSY is only for a girl child and locks in until she is 21. PPF is open to anyone with a 15-year term. Many parents use SSY for a daughter and PPF for general savings.
13Should I deposit in SSY monthly or yearly?
A single deposit early in the financial year earns the most, because the full amount gets a year of interest. Monthly deposits earn slightly less — about ₹2.5 lakh less on a ₹1.5 lakh/year plan over the full term. If you can, deposit early in April.
14Is this SSY calculator free and accurate?
Yes — it is free, needs no sign-up, and runs in your browser. It uses the exact SSY compounding (15 deposit years, maturity at 21) and the 8.2% FY 2025-26 rate, matching official figures. Future rates are set quarterly, so treat long-term numbers as an estimate.
