What corpus gives ₹1 lakh a month after work?

A lakh a month is ₹12 lakh a year

Ajmer tea-stalls use “1 lakh pension” as a blessing. Blessings do not buy units. A 4% rule buys a conversation.

₹12 lakh / 0.04 = ₹3 crore. That is the clean mapping. 5% wants ₹2.4 crore. 3% wants ₹4 crore. Pick your sleep.

Start there. Marketing copy can wait its turn.

Ajmer kitchens already know this. Relatives on the group chat are slower.

It is arithmetic plus behaviour. The arithmetic is easier.

₹1 lakh today is not ₹1 lakh in 2048. If this income starts 20 years from now, inflate it. The SIP to get there fattens.

If those two numbers already make you uncomfortable, believe them.

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

4% vs 6% taps

Decide if ₹1 lakh is today’s lifestyle or future. Future needs a bigger corpus.

Use the SWP calculator with ₹3 crore, ₹1 lakh withdrawal, 7–8% return, 25–30 years. Watch the leftover.

Open a calculator and type the ugly version first—₹2 crore corpus and ₹1 lakh SWP is 6% on day one. Fine in a boom. Mean in a 40-year winter..

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

Meanwhile SIP the gap with a 10–12% accumulation rate, not the SWP rate.

Government pension has (some) COLA. Your SWP has an Excel checkbox. Check it.

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

Pension posters vs mutual fund SWP

Mixing NPS annuity (which may be curtailed) as if it were a full ₹1 lakh SWP.

Ignoring tax slab on withdrawals and then wondering why the lakh is ₹82,000.

Rising lifestyle to ₹1.4 lakh the year after “independence” because relatives visited. Corpus is not a handshake.

The internet will sell you a one-line rule. One-line rules do not pay EMIs.

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

Re-run the numbers when salary, rate, or the goal date moves. That is the whole maintenance.

In Ajmer the skipped review later becomes a complaint about luck. It was maintenance.

Accumulate to 3 crore-ish, then sip slowly

Have ~₹3 crore and spend ₹1 lakh: start near 4%, drop to 3.5% if markets bleed.

Have ₹2 crore: the honest pension is ~₹65–70k at 4%, not a lakh.

20 years out: inflate ₹1 lakh, SIP toward that future lakh, not today’s.

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.

₹3 crore, ₹1 lakh, 25 years

₹3 crore × 4% = ₹12 lakh/year = ₹1 lakh/month pre-tax.

₹2.4 crore × 5% also prints a lakh—with less cushion.

Need this in 20 years at 6% inflation: future monthly ~₹3.2 lakh in 2046 rupees. Corpus talk jumps. Do not skip this line.

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.

Drop the return a couple of points and raise the EMI. If it breaks, you learned cheaply.

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

If you need 7% to make ₹3 crore look enough, earn more years

A lakh a month is a product of a pile and a percentage.

If the pile is imaginary, the pension is poetry.

Boring consistency beats a dramatic restart every January.

Calendar reminder beats a quote about discipline.

When someone in Ajmer 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.

Sketch, then confirm with the actual lender or a CA. This page does not sign cheques.
