How much can I withdraw monthly from ₹1 crore with no investment growth at all?
With 0% return (a conservative worst-case check), a ₹1 crore corpus from age 60 to 85 (25 years) supports a withdrawal of exactly ₹33,333 per month — this is the floor case; any positive return raises the sustainable withdrawal above this.
How this is calculated
This is the mathematical reverse of a loan EMI: instead of paying down a debt at a fixed rate, you are drawing down a corpus that keeps earning interest between withdrawals, sized so it reaches exactly ₹0 by your target age. The monthly and annual figures are calculated as two separate withdrawal schedules — they will not simply relate by ×12, since each is independently sized to fully deplete the same corpus on its own schedule.
Important: this is a level, non-inflation-adjusted withdrawal
The withdrawal amount shown stays flat in rupee terms for the whole period — it does not increase with inflation, so its real purchasing power will fall over time. It also assumes a constant annual return, which real investments will not deliver in a straight line year to year. Treat this as a starting-point estimate, not a guarantee.
What does "corpus" mean?
Corpus just means the total pot of savings you’re drawing an income from — a term used often in Indian retirement planning, but it simply means "your savings."
