PPF vs SIP for the next 15 years?

Two locks, two personalities

PPF for 15 years is a contract. SIP for 15 years is a mood. Run both if 80C is already the PPF lane and salary still has a remainder.

PPF rates move by government notification, stay around the 7% neighbourhood, and come with EEE and a long lock. That boredom is the product.

Start there. Marketing copy can wait its turn.

I keep seeing people in Madurai argue this on family WhatsApp like it is a moral issue.

The spreadsheet is the easy half. The debit surviving April is the rest.

An equity SIP’s 12% sketch is not a cousin of 7% PPF. It is a different animal that can look like −20% in year 3.

When the gap looks ugly, the gap is doing its job.

A dated goal in a small-cap fund is how holidays become credit-card stories.

Put both 15-year cheques on paper

Map 80C: EPF, insurance, tuition, PPF, ELSS. The leftover rupees decide the fight more than Twitter.

Ask if you need a known floor at year 15 (house gap, parent). Floor → PPF. Upside with bruises → SIP.

Open a calculator and type the ugly version first—₹22.5 lakh contributed, PPF ~₹38 lakh versus SIP sketch ~₹63 lakh—or SIP at ₹28 lakh if you sold in a crash.

If the input only works in a good year, it is a wish, not a plan.

If you pick SIP, write a no-redeem rule till year 12 unless the goal itself changed.

If 80C is empty, filling PPF first is a reasonable adult move. If EPF already ate 80C, the PPF-vs-SIP fight is mostly about liquidity and nerve.

If you cannot explain the result to a slightly impatient parent, you do not understand it yet.

False fights

Closing PPF because “equity returns more” and then checking SIP daily like a cricket score.

Skipping SIP entirely at 28 because PPF is “safe,” then needing equity at 50 with no practice.

Opening five PPF accounts via relatives. That is a problem, not extra compounding.

Reels compress this into a punchline. Your salary does not compress.

Your cousin’s 2017 small-cap luck is not a policy.

Change the input when life changes. Loyalty to old Excel is how people drift.

Madurai is full of people who had a decent plan in 2022 and a folklore in 2026. The folklore started as an unopened app.

80C lane vs surplus lane

Want a floor plus 80C: PPF up to the cap, SIP outside.

EPF already full 80C and you are 30 with a emergency fund: lean SIP, tiny extra PPF optional.

Hate red numbers: PPF + maybe a hybrid SIP, not a small-cap to prove courage.

Order of operations still applies: high-cost debt, then a cash buffer, then this debate.

Investing while revolving a 36% card is theatre.

A thinner SIP or a slower prepay still exists. A six-month disappear does not.

A smaller SIP or a shorter loan goal beats a heroic screenshot you cancel in six weeks.

₹12,500 in PPF vs ₹12,500 in SIP

₹1.5 lakh a year in PPF ~7.1% for 15 years sketches near ₹38 lakh. ₹12,500 SIP at 12% sketches near ₹63 lakh.

The extra ₹25 lakh is not free. It is sitting through years Madurai heat and a red Nifty.

₹8,000 PPF-equivalent yearly plus ₹8,000 SIP is a mixed landing: less bragging, fewer 3 a.m. offloads.

None of this is a guaranteed NAV or a sanctioned loan. It is a map.

If the plan only works at 18% returns or a 6% home loan forever, it is not a plan.

Stress it at a worse rate. If it still stands, you can live with the nicer years too.

Keep a 10% haircut for tax, fees, or the extra month the builder delays.

You can run both without a speech

Assign jobs: PPF is ballast and 80C. SIP is growth with a seatbelt.

Fifteen years will pass anyway. Pick a mix you will not cancel in year four.

Quiet deposits look dull until they are the only thing that showed up.

Calendar reminder beats a quote about discipline.

When someone in Madurai asks, share the widget with your numbers stripped. Let them type theirs.

And please date your spreadsheet. Future you will not remember which fantasy version this was.

Use this to think. Use a human with a licence before you transfer.
