Corpus at age 40 for different withdrawal rates
A lower starting rate means a bigger corpus but a longer retirement; the last column assumes 9% a year after retiring.

Saving path from age 30: ₹2,22,000 a month, rising 7% a year
The corpus lags the target for most of the journey and catches it in the final years, when compounding is largest.

| 31 | ₹2,22,000 | ₹26.64 L | ₹28.2 L | ₹3.63 Cr | 8% |

Same ₹1,00,000 a month, different retirement ages
Retiring ten years earlier needs a similar corpus in today's money but far larger monthly saving, because compounding has less time.
| Retire at | Years to save | Corpus then | In today's money | Monthly SIP from zero |
|---|---|---|---|---|
| Age 40 | 10 years | ₹6.14 Cr | ₹3.43 Cr | ₹2,22,000 |
| Age 45 | 15 years | ₹8.22 Cr | ₹3.43 Cr | ₹1,28,000 |
| Age 50 | 20 years | ₹11 Cr | ₹3.43 Cr | ₹83,000 |
| Age 55 | 25 years | ₹14.71 Cr | ₹3.43 Cr | ₹57,000 |
Questions about this scenario
How much corpus do I need to retire at 40 with ₹1,00,000 monthly expenses?
About ₹6.14 Cr at 40, which is ₹3.43 Cr in today's money. Your ₹1,00,000 a month grows to ₹1,79,085 after 10 years of 6% inflation, and a 3.5% first-year withdrawal rate means the corpus is 28.6 times that year's spending.
What monthly SIP do I need from age 30 to retire at 40 on ₹1,00,000 a month?
About ₹2,22,000 a month to start, rising 7% every year, assuming 11% returns. Over 10 years you invest ₹3.68 Cr and growth adds ₹2.47 Cr. Starting five years later would need ₹6,84,347 a month for the same corpus. The SIP rises each year with your pay and ends at ₹4,08,138 a month.
Will ₹6.14 Cr last if I retire at 40 and spend ₹1,00,000 a month?
In this model the money pays your inflation-linked spending beyond age 100 at 9% returns after retirement. With a 4% starting rate the smaller corpus of ₹5.37 Cr runs out around age 85. Real markets are uneven, so test the plan against bad early years.

What the numbers say about retiring at 40 on ₹1,00,000 a month
Spending ₹1,00,000 a month today means ₹1,79,085 a month at 40, because 6% inflation over 10 years multiplies prices by 1.79. Withdrawing 3.5% of the corpus in the first year, you need ₹6.14 Cr at 40. That is ₹3.43 Cr in today's rupees and 28.6 times a year of spending.
Starting from nothing at 30, a first-year SIP of ₹2,22,000 that rises 7% every year reaches that corpus at 11% a year. You would put in ₹3.68 Cr and growth supplies the other ₹2.47 Cr, 40% of the corpus. The SIP ends at ₹4,08,138 a month, and the last three years alone add 46% of the final amount.
Retirement here must cover 50 years to age 90. With 9% returns after retiring, a 3.5% corpus pays your inflation-linked spending beyond age 100. A corpus built on the 4% rule would be ₹5.37 Cr and runs out around age 85; a 3% rule asks for ₹7.16 Cr.
Waiting matters more than the amount. If you begin saving at 35 instead of 30 and still want to stop at 40, the first-year SIP for the same corpus is ₹6,84,347, which is 3.1 times as much. Every extra ₹10,000 of monthly spending at retirement adds about ₹61.4 L to the corpus you need.
A starting SIP of ₹2,22,000 is beyond most salaries, so at this age the realistic routes are existing assets, a much lower spending level or a later retirement age; the tables above show each. Treat the corpus as a starting point. It assumes steady returns, spending that rises only with inflation and no large medical bills, and it leaves out your house and emergency fund. The FIRE calculator lets you change each of these assumptions.
