Sukanya Samriddhi vs mutual fund SIP for daughter — the 18-year math
₹1.5L into SSY at 8.2% tax-free gives ₹71L at age 21. Same into equity SIP at 12% gives ₹1.45 crore — but with volatility. Here's the honest comparison + the 70:30 blend that wins.
The Sukanya Samriddhi Yojana (SSY) tagline is "8.2% tax-free for your daughter's future" — a great rate, sovereign backing, EEE tax treatment. Most parents stop there. The honest comparison: at the same monthly investment, an equity mutual fund SIP at 12% historical CAGR delivers roughly double the corpus by age 21. So why isn't SSY a clear loser? Because risk-adjusted, the answer is more nuanced.
The two plans
| Sukanya Samriddhi Yojana | Equity Mutual Fund SIP | |
|---|---|---|
| Eligibility | Girl child < 10 yrs old | Any age — parent invests on behalf |
| Rate | 8.2% (Govt-notified, varies quarterly) | 10-14% historical (variable, real-world risk) |
| Tax treatment | EEE — fully tax-free | LTCG 12.5% above ₹1.25L/year |
| Lock-in | Until daughter turns 21 (partial w/d allowed Y18) | None for plain MF; 3Y for ELSS |
| Annual contribution limit | ₹1.5 lakh | No limit |
| Term | 21 years (deposits for first 15 years only) | Flexible — any term |
| Risk | Sovereign — zero default risk | Equity market volatility, possible -30% in single year |
| 80C deduction | Yes (old regime, ₹1.5L cap) | Only ELSS qualifies (3Y lock) |
The 18-year math — ₹12,500/month each
Two parents start the same month for a 3-year-old daughter. One deposits ₹12,500/month into SSY (₹1.5L annual cap). Other does ₹12,500 SIP into a flexi-cap mutual fund.
| SSY @ 8.2% (assuming rate constant) | Equity SIP @ 12% CAGR | |
|---|---|---|
| Monthly deposit | ₹12,500 | ₹12,500 |
| Total invested (15 years of deposit) | ₹22,50,000 | ₹22,50,000 (continued 18 years for full SIP horizon) |
| Corpus at year 15 (end of deposits) | ₹47,30,000 | ~₹62,00,000 |
| Corpus at year 18 (daughter age 21) | ~₹71,00,000 (compounds further) | ~₹1,45,00,000 |
| Tax on exit | Zero (EEE) | ~₹15-17L LTCG tax over 18Y if harvesting; ~₹15L lump-sum LTCG if redeemed all at once |
| Net in hand | ₹71 lakh | ₹1.28-1.30 crore |
Equity SIP wins by roughly ₹57-60 lakh on the same monthly investment. That's college fees abroad vs college fees in India — material life impact.
But the equity assumption is fragile
Historical Indian equity mutual fund return over rolling 15-year windows since 1999:
- Best 15-year window: 18.4% CAGR
- Median window: 13.1% CAGR
- Worst window: 6.9% CAGR (still beats SSY barely)
- Worst single year within these windows: -52% (2008)
So the 12% assumption is the median. If you got the worst window, you'd be at ~₹76 lakh — barely better than SSY's ₹71L. And riding through a -52% year requires nerves of steel when it's your daughter's college fund.
The hybrid play — 70:30 SIP:SSY split
Most child-finance practitioners settle on a blended approach. Same ₹12,500/month:
- ₹4,000/month into SSY (₹48K/year, well under ₹1.5L cap)
- ₹8,500/month into equity SIP
Projected corpus at age 21:
- SSY portion: ~₹22 lakh tax-free
- SIP portion: ~₹99 lakh, net of LTCG ~₹85 lakh
- Total: ~₹1.07 crore
This captures most of the equity upside (75% of pure SIP outcome) while keeping a SSY anchor that guarantees ~₹22 lakh regardless of equity performance. Even if equity disappoints to 7% CAGR, you still have ~₹65 lakh + ₹22 lakh = ₹87 lakh. Floor protected.
Why ₹4K, not more or less, into SSY?
Three reasons:
- 80C cap is ₹1.5L total — likely also has PPF, ELSS, EPF competing. ₹48K of SSY is realistic.
- Floor coverage — ~₹22L SSY corpus covers Indian engineering / undergrad even in worst case. Equity upside is bonus.
- Diversification — too much SSY = sovereign risk + rate-cut risk over 15 years. Recent 0.2% cut in October 2023 (8.4 → 8.2) shows rates can move down.
What about gold MF / PPF in the mix?
PPF can be opened for a minor (in parent's name as guardian). 7.1% tax-free vs SSY's 8.2%. SSY wins on rate. Same lock-in horizon. Skip PPF for a daughter unless you've maxed SSY.
Gold MF / SGB serves as a 10–15% allocation for diversification. Not for primary child corpus building due to slab rate taxation (gold MF) and 12.5% LTCG (SGB secondary).
The flexibility comparison
- Need cash for medical emergency: SSY says no till year 18; SIP says yes (liquid in T+1)
- Daughter wants to study abroad at 18: SSY allows partial withdrawal of up to 50% from year 18; SIP gives 100% liquidity
- Daughter wants to start business at 22: SSY matures at 21; SIP can stay invested indefinitely
- Rate cut to 6.5% in 5 years: SSY suffers; SIP unaffected
Equity SIP wins on flexibility hands down. The catch is your own discipline — SSY's lock prevents impulse withdrawal. SIP requires you NOT to redeem during -30% years.
How to open SSY (the practical bit)
- Visit any post office or designated bank branch (SBI, BoB, PNB, Canara, BoI, Union, Axis, ICICI, HDFC)
- Carry: daughter's birth certificate, your PAN, your Aadhaar, your address proof, passport-size photo
- Min deposit ₹250, max ₹1.5L per FY — flexible per month or one-time annual
- Account opens in 24 hours; passbook issued
- Subsequent deposits via cheque / online banking / UPI to the SSY-linked account
Two daughters in family → one SSY each. Twins / second girl child → exception allows third SSY.
Tax math for the new regime question
SSY's 80C benefit is available only under the old tax regime. Under default new regime (FY 2026-27), the contribution is not deductible, but the 8.2% interest + maturity remain tax-free. So:
- Under new regime, SSY is essentially a "tax-free 8.2% safe-debt parking" — still beats most alternatives for the child-corpus use case
- Under old regime, you also get ₹1.5L deduction — ₹46K immediate tax saving for 30% slab

FAQs
Can the daughter herself contribute to SSY after a certain age?
Yes, after age 18 she becomes the account holder and can operate it herself, including making deposits. Earlier than that, only the guardian (parent) can contribute.
What happens if rate drops to 7%?
SSY rate is revised quarterly — it can move down. The corpus from past years compounds at the rate that was prevailing when interest was accrued. New deposits earn the new rate.
Can I close SSY before maturity for non-marriage reasons?
Premature closure allowed only on (a) marriage of girl after age 18, (b) death of account holder, (c) extreme compassion grounds (life-threatening illness, death of guardian). Otherwise locked till maturity.
Is SSY available for daughter living abroad?
SSY is restricted to Resident Indians. If daughter becomes NRI (e.g., for study), the account continues till maturity but no new deposits are allowed during NRI status.
Should I open SSY in joint name with my wife?
SSY is single-guardian. One parent operates the account. Switching guardian (e.g., from father to mother) is allowed once via formal application.
What if my daughter is exactly 10 on the day I want to open SSY?
Cut-off is "below 10" — so any age 0 to 9 years 364 days is eligible. Day she turns 10, the window closes for new accounts. Don't postpone.
