The number

Annual must-pay times a multiplier is a sketch. Know what the sketch ignores.

People quote 25× yearly spend (from a 4% withdrawal shorthand). If you spend ₹12 lakh a year in today’s rupees, 25× is ₹3 crore. That sentence is a napkin, not a guarantee.

What the napkin is doing

It assumes you can take a small slice of the pile each year and the rest keeps working. In some histories that worked for a 30-year retirement in some countries. In other histories, the first decade was cruel and the slice was too hungry.

What the napkin ignores in India

Inflation path, especially medical
Sequence: retiring into a crash
No copy-paste Social Security
EPF / NPS withdrawal shapes
Family dependents who are not in the ₹12 lakh
The house you live in (shelter, not a tap)
Longevity - plans can need 30–40 years

So: compute 25× as a *startle number*. Then raise the spend to include the people you will actually support. Then remember it is still a sketch.

Another sketch: work years and monthly add

Current pile + monthly add + years + a cautious growth guess. Every growth guess is the most dangerous line on the page. Show it as a range, not a destiny.

**Note:** Multipliers and 4% rules are teaching tools from specific studies and markets. They are not Indian law and not a promise. Educational, not advice.

Where it breaks

Treating 25× as a finish line, then spending 6% because a reel said so. Using last year’s 18% as the growth guess.

25× is a napkin.
Raise the spend to include real dependents and health.
Any growth guess belongs in a range.
