“I want ₹1 crore by 60.” The planner's first question back: “How old are you now?” At 25, the answer is ~₹2,800/month. At 35, ~₹8,000. At 45, ~₹28,000. Same crore, 10× monthly cost — timing is the dominant variable, bigger than returns, bigger than the starting amount. This guide works backwards from ₹1 crore across start ages, shows the early-vs-late gap in hard numbers, and adjusts for inflation so the target means something at withdrawal.
Part of the India wealth & tax guide. Plan it in the retirement calculator; model monthly legs in the SIP calculator.
Work backwards: monthly SIP per start age (12%, ₹1Cr at 60)
| Start age | Years | Monthly SIP ≈ | Total invested |
|---|---|---|---|
| 25 | 35 | ₹2,800 | ₹11.8L |
| 30 | 30 | ₹5,000 | ₹18.0L |
| 35 | 25 | ₹8,000–9,000 | ₹27L |
| 45 | 15 | ₹28,000 | ₹50.4L |
Annuity math (PMT×(((1+mr)^n−1)/mr)) rewards duration exponentially: five early years beat higher payments later — 25-vs-35 at ₹500/month already gaps ₹7.9L by 60. Late starters bridge with step-ups plus lump-sum seeds (bonus, arrears) rather than unaffordable flat SIPs. Verify your exact age band with presets before committing.
Shortfalls, inflation haircuts and the 4% lens
Two adjustments before celebrating: inflation haircut — ₹1 crore in 2045 spends like ~₹31L today at 6% (see real returns), so target ₹3Cr nominal for ₹1Cr real; and shortfall planning — a ₹20L gap at 60 needs either +₹3,500/month for the last decade or 2 extra working years, quantified in the retirement calculator with nominal, real and shortfall outputs. The 4% withdrawal lens: ₹1Cr supports ~₹33,000/month inflation-adjusted — size lifestyle to that, not to the crore number itself.
₹500 vs ₹800 monthly: the ₹3.7L lesson
Same 30 years at 7%: ₹500/month → ~₹6.1L, ₹800/month → ~₹9.8L — a ₹300 habit gap compounds to ₹3.7L. Small-step framing beats crore-intimidation for beginners: start ₹500 (or theSeed-plus-SIP combo), step up 10% yearly, review at each milestone. Early-vs-late evidence again: a 25-year-old's ₹500 beats a 35-year-old's ₹800 over the same finish line. Parents: a minor's 15-year head start is the highest-ROI gift in personal finance — open early, automate, ignore.
