Five smart nudges
Use the result with context.
Deposits are permitted for 15 years from opening; normal maturity is 21 years from opening.
Depositing before the fifth can give money more time in the monthly interest calculation.
Education withdrawals are conditional and generally capped at 50% under the scheme rules.
Recheck notified rates because today’s rate is not locked for 21 years.

How a Sukanya Samriddhi account grows
Sukanya Samriddhi is a guardian-operated small-savings account for an eligible girl child. Deposits are permitted for 15 years from opening, while the account ordinarily matures 21 years from opening unless an applicable closure event occurs earlier. This calculator separates those two clocks: contributions stop after the deposit period, but the accumulated balance continues earning the selected rate until maturity. That distinction is why a child’s current age and account-opening timing matter more than a generic 21-year compound-interest formula.
The Government notifies the rate periodically; 8.2% is not a contractual rate for the full term. The projection uses one constant assumption so families can compare contribution plans. Run a lower-rate scenario, because a long education plan that works only at today’s rate has little safety margin.
Worked example for an education goal
Assume a parent opens the account when a daughter is three and deposits ₹1.5 lakh each year for 15 years. Total deposits are ₹22.5 lakh. The balance can continue compounding after contributions stop, which is a major part of the eventual maturity value. Now compare that result with an education goal costing ₹25 lakh today and inflating at 8%: after 15 years the course could cost roughly ₹79 lakh. The scheme corpus may fund a large portion without necessarily covering the entire goal.
This comparison exposes the common mistake of comparing a nominal maturity value with today’s fee. Education inflation, foreign-currency exposure and living costs need separate assumptions. A family may combine this account with diversified market-linked investments rather than raising the scheme rate to force the calculator to meet the target.
Eligibility, deposits and withdrawals
Opening age, number of accounts, minimum and maximum annual deposits and guardian documentation are governed by the scheme rules. The calculator enforces the annual ceiling but cannot determine whether the child or guardian is eligible. Missing the minimum deposit can make an account irregular until revived according to the applicable process.
Withdrawals for education and closure around marriage are subject to age, purpose, timing and documentation conditions. Treat those as conditional access, not on-demand liquidity. If tuition is due before the account’s normal maturity, map the permitted withdrawal date to the academic schedule and keep a separate liquid buffer for admission deposits and expenses that may not qualify.
Tax treatment and family planning
Qualifying contributions may fall within the guardian’s applicable section 80C limit under the old regime, while interest and qualifying maturity proceeds are generally exempt. The contribution does not create an unlimited or separate deduction; it competes with other eligible items within the available limit. Tax rules and the chosen regime must be checked for the relevant year.
The account is dedicated to the beneficiary, which is valuable for goal discipline but reduces flexibility. Parents should also maintain adequate life and health insurance, nominations and a plan for who continues deposits if the primary earner dies or loses income. A large projected corpus is not a substitute for that protection planning.
Sukanya versus PPF and an equity SIP
Sukanya offers a dedicated sovereign-backed structure and a rate that has often differed from PPF, but access and beneficiary rules are narrower. PPF is not child-specific and has its own 15-year term. An equity SIP has no government-guaranteed return and can be volatile, yet may provide greater long-term growth potential and flexibility. The products solve different parts of an education plan.
A sensible comparison fixes the same education date and future cost, then allocates between stable and growth assets. Do not compare an 8.2% scheme assumption with a 12% equity assumption as if both are equally certain. Stress the equity return and the small-savings rate, and reduce market risk as the fee date approaches.
Planning checklist for parents
Verify the account-opening date, remaining deposit years, deposits already made this financial year, beneficiary documents, nomination or succession arrangements and the likely year of education withdrawals. Estimate tuition and living costs separately and apply an education-specific inflation assumption.
Review the account after every notified-rate change and at least three years before the first planned withdrawal. If the projected shortfall is growing, increase the separate investment contribution or revise the goal funding plan rather than assuming the scheme’s rate will rise.

Sukanya calculator FAQs
Why do deposits stop before Sukanya maturity?
The scheme separates a 15-year contribution period from the longer account term. The existing balance may continue earning after deposits stop.
Is 8.2% guaranteed until maturity?
No. The rate is notified periodically. The calculator uses a constant rate only as an assumption.
Can the account fund college before 21 years?
Education withdrawals are possible subject to the scheme’s age, amount, purpose and documentation rules. Map those conditions to the actual admission timeline.
Does a ₹1.5 lakh deposit give a separate tax deduction?
No separate unlimited deduction arises. Eligibility depends on the tax regime and the available overall limit for the relevant year.
Should parents use only Sukanya for education?
Not necessarily. The future education cost, inflation, liquidity and risk capacity may justify combining stable and growth assets.
