India's SIP machine keeps humming: AMFI data shows Rs 31,781 crore flowed in via SIPs in June 2026

India's retail investors wrote another large cheque to the equity market in June 2026. AMFI's monthly data shows Rs 31,781 crore flowed into mutual funds through systematic investment plans in that single month, extending a run of steady monthly contributions that AMFI has tracked month by month since FY 2016-17 (amfiindia.com). If that June pace were sustained for twelve months it would annualise to roughly Rs 3.81 lakh crore of disciplined, rule-based buying, and SIP assets already account for close to a fifth of the industry's overall assets under management.

That number is the pulse we care about at midday: not where the index closed, but how much household saving is being routed, automatically, into market-linked instruments every month. It also sharpens an old question that every disciplined saver eventually asks. If you are going to commit a fixed sum every month for the long haul, should it go into an equity mutual fund SIP or into the Public Provident Fund? Both reward the same behaviour - regular contributions and patience - but they sit at opposite ends of the risk, return and tax spectrum. This piece compares the two for a long-term wealth goal, using only rates verified as of August 2026.

Side-by-Side Comparison

An equity SIP and a PPF account both convert a monthly habit into a corpus, but almost every other attribute differs. PPF pays a fixed 7.1% for the July-September 2026 quarter, a rate the government left unchanged at its 1 July 2026 review and will revisit on 1 October 2026. An equity SIP carries no promised rate at all; its outcome tracks the market, which is precisely why AMFI's Rs 31,781 crore June figure is a story about risk appetite, not a guaranteed return.

The arithmetic of contribution is identical on both sides. A Rs 10,000 monthly SIP puts in Rs 1.2 lakh a year, or Rs 18 lakh of principal across a 15-year run. PPF caps you at Rs 1.5 lakh a year, so a saver maximising it contributes Rs 22.5 lakh of principal over the same 15 years. Where the paths diverge is the return engine. If the current 7.1% were held for the full 15-year term, a maximised PPF (Rs 1.5 lakh deposited near the start of each year) would mature at roughly Rs 40.7 lakh, entirely tax-free - though the quarterly reset means the real figure moves with every rate revision after 1 October 2026. An equity SIP has no such fixed formula: model your own assumption on the SIP calculator rather than trusting any single projected number, because past index performance is not a promise. You can size a fixed-rate PPF outcome precisely on the PPF calculator.

The behavioural point is what AMFI's data really captures. Both products convert market timing into a non-decision through rupee cost averaging: the same rupee amount buys more units when prices fall and fewer when they rise. PPF applies the same monthly discipline to a fixed-rate instrument, so the compounding frequency - annual for PPF - does the heavy lifting instead of the market. The Rs 31,781 crore that arrived in June 2026 is, in effect, a nationwide vote for automating the decision to invest.

Tax Treatment

Tax is where the 7.1% PPF headline and a market-linked SIP become genuinely hard to compare, because they are taxed on opposite principles. PPF sits in the exempt-exempt-exempt category: contributions can qualify for Section 80C deduction of up to Rs 1.5 lakh in the old regime, the annual interest is exempt, and the maturity value is exempt under Section 10(11) of the Income-tax Act (incometax.gov.in). Equity SIP units are taxed only on exit, and the rate depends on how long you held each tranche.

For equity mutual funds, gains on units held 12 months or longer are long-term capital gains, taxed at 12.5% after an annual exemption of Rs 1.25 lakh, both set by Budget 2024 and effective from 23 July 2024. Units sold within 12 months attract short-term capital gains tax at 20%. A worked case: if you redeem equity units in FY 2026-27 with a Rs 3,00,000 long-term gain, the first Rs 1,25,000 is exempt and the remaining Rs 1,75,000 is taxed at 12.5%, a bill of Rs 21,875 before cess. Health and education cess of 4% applies on top of the tax, per the same Income-tax Act rates.

The regime choice quietly reshapes the comparison. Under the new regime that most taxpayers now default to, the Section 80C deduction is unavailable, so a PPF contribution earns no upfront tax break - only its interest exemption survives. That still matters, because the 7.1% PPF return is tax-free in the hand, whereas an equity SIP's 12.5% LTCG is a real drag on the compounding above the Rs 1.25 lakh annual shield. Note too that the new regime's Section 87A rebate now runs to Rs 60,000 for total income up to Rs 12,00,000 in FY 2025-26, against Rs 12,500 up to Rs 5,00,000 in the old regime, which can push a modest-income saver's effective tax on small equity gains close to nil. If you are choosing ELSS specifically for the deduction, weigh it on the ELSS calculator and read the mechanics on the ELSS glossary entry.

Who Should Pick Which

The Rs 31,781 crore June 2026 flow masks a wide range of individual situations, and the right split is a function of horizon, risk tolerance and tax regime rather than a single winner. The framework below maps common investor profiles to a starting stance, all anchored to the rates verified for August 2026.

A saver in their late twenties with a retirement or house-deposit goal 15 or more years away has time on their side: the open-ended equity SIP, held past 12 months, is taxed at just 12.5% on gains beyond the Rs 1.25 lakh annual exemption, and the long horizon is what lets rupee cost averaging work through market cycles. For this profile the PPF is best treated as ballast - a slice of the monthly contribution parked at a guaranteed 7.1% to steady the overall portfolio, not the main engine.

A conservative saver who cannot stomach a falling NAV, or who is within five years of the goal, should tilt the other way. PPF's 7.1% is modest, but it is sovereign-backed and tax-exempt under Section 10(11), and its 15-year lock-in enforces the very discipline that makes SIP data impressive in the first place. An old-regime taxpayer chasing the Section 80C deduction of Rs 1.5 lakh has a genuine either-or: ELSS delivers the same deduction with a shorter three-year lock-in and equity upside, while PPF delivers it with capital protection. For a new-regime taxpayer, 80C is moot, so the decision reduces to pure risk-return - most will run a diversified equity SIP as the core and keep a smaller PPF holding for its tax-free, guaranteed layer.

The honest answer for the largest group is "both, in a ratio you can hold through a downturn." The Rs 31,781 crore that flowed in during June 2026 is only wealth-building if the same investors keep contributing when the market is down 20%, and a PPF sleeve is often what stops a nervous saver from stopping the SIP.

How To Start Either, Cleanly

Getting the plumbing right matters more than the product debate for the first year. A PPF account can be opened at a bank or post office with a Rs 500 minimum and funded up to Rs 1.5 lakh a year; the interest is credited annually at the notified rate, currently 7.1% for July-September 2026. An equity SIP needs a completed KYC and a chosen scheme, after which a fixed date auto-debit does the work - which is exactly the mechanism behind AMFI's Rs 31,781 crore monthly figure. Whichever you pick, automate the debit within two days of salary credit so the contribution is made before the money is spent, and revisit the split, not the habit, once a year.

FAQ

What was the AMFI SIP inflow figure for June 2026?

AMFI's monthly data records Rs 31,781 crore collected through systematic investment plans during June 2026, continuing a run of steady monthly SIP contributions that AMFI has published month-wise since FY 2016-17 (amfiindia.com). SIP assets are roughly a fifth of the industry's total assets under management.

Is PPF or an equity SIP better for a 15-year goal?

Neither is universally better. PPF pays a fixed, tax-exempt 7.1% for July-September 2026 with sovereign backing, while an equity SIP is market-linked with no guaranteed return but is taxed at only 12.5% on long-term gains above Rs 1.25 lakh a year. Over 15 years an equity-tilted split has historically carried more upside and more volatility; the right mix depends on your risk tolerance, not a single number.

How are equity SIP gains taxed in FY 2026-27?

Gains on equity fund units held 12 months or longer are long-term capital gains, taxed at 12.5% after an annual exemption of Rs 1.25 lakh, per Budget 2024 effective 23 July 2024. Units held under 12 months attract short-term capital gains tax at 20%. A 4% health and education cess applies on the tax.

Does PPF still get a tax deduction under the new regime?

No. The Section 80C deduction of up to Rs 1.5 lakh, which PPF contributions can claim, is available only in the old regime. Under the new regime you get no upfront deduction for a PPF contribution, but the interest and maturity remain exempt under Section 10(11) of the Income-tax Act regardless of regime.

What is the PPF interest rate right now?

The PPF rate is 7.1% per annum for the July-September 2026 quarter, left unchanged by the government at its 1 July 2026 small-savings review. It is next scheduled for review on 1 October 2026, so any illustration assuming 7.1% for a full 15-year term is only indicative.

Can I run both a PPF and an equity SIP at the same time?

Yes, and most disciplined savers do. A common approach is to route the core monthly contribution into a diversified equity SIP for long-term growth and keep a PPF sleeve, capped at the Rs 1.5 lakh annual limit, as a guaranteed, tax-free ballast. Model each leg separately on the SIP calculator and the PPF calculator.

How do I decide the split between the two?

Anchor it to your horizon and your ability to hold through a fall. A longer horizon and a higher tolerance for a falling NAV argue for a larger equity SIP share taxed at 12.5% LTCG; a shorter horizon or a need for capital protection argues for more PPF at its fixed 7.1%. Old-regime taxpayers may prefer ELSS over PPF to combine the Section 80C deduction with equity upside.
