How Much SIP Do You Need to Retire at 40, 45, 50?

Early retirement in India requires a corpus large enough to sustain 30-40 years without employment income. We calculate the exact monthly SIP for each retirement age.

1.The retirement corpus formula every Indian needs to know

Your target retirement corpus = Annual expenses at retirement ÷ safe withdrawal rate. For India, most planners use 3-3.5% safe withdrawal rate (lower than the US 4% due to higher inflation). If your current monthly expense is ₹80,000 (₹9.6 lakh/year) and inflation is 6%, your expenses at age 45 (10 years from now at age 35) will be ₹17.2 lakh/year. Corpus needed at 3.5% SWR = ₹17.2 lakh ÷ 0.035 = ₹4.9 crore. This is your retirement number.

2.Retirement at 40: the most aggressive and least forgiving target

Retiring at 40 means 40-45 years of corpus drawdown (assuming life expectancy of 80-85). If you're currently 25 and have 15 years to build the corpus: to accumulate ₹5 crore by age 40 at 12% CAGR, you need a SIP of ₹98,000/month. If you add a 10% annual step-up starting from ₹50,000/month, you can also reach ₹5 crore in 15 years. These are large numbers — retiring at 40 is realistically achievable only for founders, early equity employees, or very high earners (₹40L+ CTC) who started young.

3.Retirement at 45: the achievable sweet spot for disciplined savers

Starting at age 25, you have 20 years. To build ₹5 crore by 45 at 12% CAGR requires ₹50,000/month flat SIP — or ₹26,000/month with a 10% step-up. Starting at 30 (15 years), the requirement jumps to ₹98,000/month flat or ₹50,000/month with step-up. The 20-year window from age 25 is the golden period: ₹50,000/month is ~25% of a ₹24 lakh CTC, aggressive but achievable. This assumes your lifestyle expenses are ₹70,000/month in today's rupees.

4.Retirement at 50: the most popular and most realistic FIRE target

At 50, you have 30-35 years of corpus drawdown — still long, but more manageable. If retiring at 50 with current monthly spend of ₹80,000 (inflated to ₹2.87 lakh by age 50 at 6%): corpus needed = ₹34.4 lakh/year ÷ 3.5% = ₹9.8 crore. That sounds enormous, but with EPF (likely ₹1.5-2 crore), NPS, and real estate equity, the gap may be only ₹5-6 crore. A SIP of ₹40,000/month from age 30 for 20 years at 12% gives you ₹3.98 crore — add EPF, NPS, and other assets, and ₹50 retirement becomes feasible.

5.The post-retirement portfolio: where to park the corpus

A ₹5 crore corpus at retirement shouldn't all be in equity. Standard advice: 60% in balanced/hybrid funds, 30% in debt funds and FDs, 10% in liquid funds for 12-18 months of expenses. Withdraw from liquid first, replenish from hybrid. This "bucket strategy" means your equity allocation grows over time, countering sequence-of-returns risk. Avoid withdrawing from equity in the first 2-3 years of a market crash — keep 3 years of expenses in FD always as a buffer.
