What corpus if I want to retire at 45?

Forty-five is early. The math is longer

Thrissur wedding circuits sell “retire at 45.” They do not sell 40 years of medical inflation.

From 45 to 85 is 40 years. A 4% SWP on ₹3.5 crore is ₹14 lakh/year. Feel the length.

Start there. Marketing copy can wait its turn.

In Thrissur this debate still shows up at dinners as if character, not cash flow, is the variable.

It is arithmetic plus behaviour. The arithmetic is easier.

If you are 32 with 13 years, ₹3.5 crore at 12% wants a monstrous SIP (order of ₹90,000–₹1 lakh) unless you already have a pile. Most people need 50, not 45—or a lower spend.

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

A retirement chart that needs 14% forever is a holiday brochure.

Accumulation window is short if you start at 32

Pick spend at 45 in today’s rupees, inflate, multiply by 30–33 because the horizon is long.

Then SIP the gap with the widget. If the debit is fantasy, the date moves to 50–52. That is a plan too.

Open a calculator and type the ugly version first—13 years × ₹25,000 SIP will not print ₹3.5 crore. The calculator will hurt. Good..

Type the version that would still stand after a bad bonus year.

Build a 5-year spending bucket before the last working Friday.

NPS may not unlock the way a 45-year-old Instagram wants. Do not count locked EPF/NPS as fully liquid FIRE cash on your 45th birthday.

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

NPS lock-ins versus a 45-year-old who wants a beach

Counting house value as retirement income you will never sell or rent.

Assuming you will “consult at lakhs” to cover a thin corpus. Consulting is a job with a nicer logo.

Zero health cover because “I’m young at 45.” Young is not a deductible.

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

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

When the salary or the date moves, reopen the calculator. Do not recycle last year’s PDF.

People in Thrissur skip that and then call the failed plan “the market.” It was the skipping.

Earn faster or spend smaller

Already 40% of the corpus at 36: 45 might be a conversation.

Starting from near-zero at 32: aim 50–55 unless spend is student-level and stays there.

Spouse works: two SIPs, one plan, honest combined spend.

Buffer first, ugly debt second, this goal third. Reverse it and the goal becomes a loan.

Investing while revolving a 36% card is theatre.

Small and dated beats heroic and cancelled.

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

Age 32 to 45: 13 years of SIP

₹3.5 crore, 4% = ₹1.17 lakh/month gross before tax. Still not infinite.

₹50,000 SIP × 13y @12% ≈ ₹1.6 crore sketch—not the ₹3.5 crore speech.

Delay “retire” to 52, same SIP: the extra 7 years do more than a motivational book.

Those are planning numbers, not a promise from a mutual fund or a bank RM.

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

Good years are a bonus. Plans that need good years are costumes.

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

If 45 only works with a side hustle forever, say so

45 is allowed. Lying about the SIP is not.

If the only way to 45 is 18% and no hospital bill, you chose a brand, not a date.

The unsexy month-on-month debit still beats a new “system” in April.

Calendar reminder beats a quote about discipline.

Do not forward a 40-message thesis. Send the tool and the date you used.

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.
