How much SIP do I need for a home down payment in 5 years?
Five-year down-payment SIPs usually need a bigger monthly number than people guess—plus a buffer for fees and price jumps.

Start with the brochure number, not WhatsApp vibes
Your friend drops a message: “Flat is ₹80 lakh, they want 20% down. How much SIP?” That is ₹16 lakh in five years—before registration, interiors, and the “oh we forgot brokerage” line.
Round it up. Plan for ₹18–20 lakh so you are not selling units the week after booking.
I have seen people plan exactly ₹16 lakh and then scramble for ₹2 lakh from parents. Awkward.
Plug ₹20 lakh, 5 years, and a conservative 10–12% expected return into a SIP calculator.
At ~12%, you are looking at roughly ₹25,000–₹27,000 a month as a flat SIP.
If that number makes your stomach drop, good—better now than at the banker’s desk.
At 10%, the monthly ask climbs further. Don’t pretend 15% will save you.
Brochure down payment is only the starting line. Stamp, interiors, and a price buffer eat the rest.
Do the ugly extras math once
Stamp duty and registration alone can eat 5–8% depending on the state. That is not a tip jar.
Interiors for a bare shell? Easily ₹8–15 lakh if you are not going full jugaad.
Parking, society deposits, mover costs—tiny individually, annoying together.
So if the builder says ₹16 lakh down, your real “ready to move in” cash need is higher.
I usually tell friends: take down payment × 1.25 as a working target for a five-year plan.
For an ₹80 lakh flat, that is closer to ₹20 lakh in the SIP bucket, not ₹16.
Yes, you might overshoot. Overshooting is a nicer problem than underfunding.
Step-up SIP if your salary actually grows
Most people cannot start at ₹27k. Be honest with your Excel, not your ego.
A step-up SIP that rises 10% each year lets you begin closer to ₹18k–₹20k and still land near the same corpus, assuming returns behave.
Example sketch: start ₹18,000, bump 10% yearly for 5 years at ~12%. You get surprisingly close to a flat ₹25k path.
Miss a raise year? Keep the old amount. Don’t cancel the SIP out of guilt.
Guilt-cancelling SIPs is a national sport. Stop playing.
Pair this with a home-loan EMI check early.
Knowing the EMI on the remaining 80% stops you from over-bidding on the flat just because the SIP “felt doable.”
Same goal, three return guesses. 12% looks friendly; 10% is the number you should still be able to live with.
Where people mess this up
Assuming 15% forever. Cute. Dangerous.
Ignoring that equity can be ugly for 2–3 years right when you need the money.
Parking the entire down-payment corpus in small-caps three years out. That one still makes me wince.
When the goal is under 3 years away, start shifting toward debt or hybrid—quietly, not in a panic sell.
Also: builders revise prices. Inflation in property is not the same as CPI.
Re-run the calculator every Diwali with the new asking price.
And please don’t “temporarily” redeem the SIP for a Europe trip in year three. I have watched that movie.
Asset mix as the date gets closer
Years 1–2: equity-heavy is fine if you can stomach red months.
Years 3–4: start peeling into hybrid or short-duration debt on a schedule.
Final 12 months: most of the booking money should not be riding Nifty daily drama.
You are not trying to maximize returns in year five. You are trying to not miss the booking cheque.
STP from liquid into equity early on is fine. Reverse STP or rebalancing later is also fine.
What is not fine: all-in small cap till the day before registry.
Write the glide path in a note on your phone. Future you is forgetful.
Tax and redemption timing
Equity LTCG rules change with budgets. Plan with a haircut.
Redeeming everything in one week for the down payment can create a tax bill you forgot to fund.
Keep a separate “tax buffer” of a few percent in safer money if the redemption is large.
ELSS only if the three-year lock-in still fits your booking timeline. Tax saving is nice; liquidity for booking is nicer.
Don’t buy ELSS in year four of a five-year house plan because a colleague saved ₹10k in tax.
Your house goal is not a tax-optimisation contest.
If you are unclear on current LTCG slabs, check once a year—not every Twitter thread.
A sample ₹80 lakh flat walkthrough
Target corpus: ₹20 lakh in 60 months.
Flat SIP at 12%: ballpark ₹25–27k/month.
Flat SIP at 10%: higher—open a calculator and face it.
Step-up 10% from ~₹18–20k: often more doable for a 28–32 year old with raises.
If your take-home is ₹70k, a ₹25k SIP plus rent will hurt. Adjust the flat budget, not physics.
Sometimes the answer is a cheaper society, not a “motivational” SIP amount.
Run EMI on ₹64 lakh too. Down payment SIP is only half the story.
What to ignore on the internet
Anyone promising “₹10k SIP = house in 5 years” without stating price and returns.
Screenshots of 40% one-year fund returns used as a 5-year plan.
Relatives saying gold will definitely beat the builder’s price hike.
FOMO reels about “last flats in this project.” Builders have invented urgency since forever.
Your SIP plan should survive a boring 8–10% return case.
If it only works at 18%, it does not work.
Boring plans buy houses. Hype plans buy regret.
