How Much SIP Do You Need for ₹1 Crore? Here Is the Actual Math

Three time horizons, three return assumptions. Pick your row honestly:

Two things jump out. First, halving the monthly burden costs you five extra years — the 15-vs-20-year rows differ by ₹10,000 a month. Second, the return assumption you argue about matters less than the years you commit: at 15 years, the entire spread between a pessimistic 10% and an optimistic 14% is ₹7,700/month, while starting five years earlier saves more than that on its own. Verify any cell of this table yourself on our SIP calculator — inputs are yours to change.

The table assumes a flat SIP — same amount for 15 years. Salaries don't work that way, and neither should SIPs. A step-up SIP increases your instalment by a fixed percentage every year, riding your increments. The effect is dramatic:

• Flat ₹20,000 for 15 years at 12% → ~₹1.0 crore, total invested ₹36 lakh.
• Start at ₹12,000 with a 10% yearly step-up, same 15 years and 12% → also lands near ₹1 crore — but your first-year burden is ₹1.44 lakh instead of ₹2.4 lakh.

The step-up ladder is how a 27-year-old on a ₹45,000 salary legitimately plans a crore without lying to themselves about affordability. The discipline required is exactly one decision per year: when the increment letter arrives, the SIP goes up before the lifestyle does. Miss that window and the money finds a car EMI instead.

Here is the part most "1 crore" articles skip. At 6% average inflation, prices roughly double every 12 years. So ₹1 crore arriving 15 years from now buys approximately what ₹42 lakh buys today. It is still a serious amount — but it is not "never work again" money, and pretending otherwise leads to under-planning.

The honest planning sequence runs backwards: decide what today's-rupees amount you actually need (say, ₹1 crore of today's purchasing power for a child's education plus retirement cushion), inflate it to the target date (roughly ₹2.4 crore in 15 years at 6%), and size the SIP against that. Yes, the monthly number gets bigger — reality usually is. The alternative is discovering the shortfall at 55, when no step-up ladder can rescue it. Our goal-planning tools do this inflation adjustment automatically.

The math above is arithmetic; the outcome is behaviour. Over a 15-year SIP you will live through at least two or three sharp market falls — 2008-style, 2020-style, or slow grinding corrections. In each one, your portfolio statement will show less than you invested, financial news will be apocalyptic, and someone in your family will suggest "abhi nikal lo, phir sasta milega". The investors who reach the crore are, almost boringly, the ones who did nothing in those moments — or better, topped up. You can see this pattern yourself: run any 15-year window through our historical backtest simulator and watch how every crash on the chart became a discount in hindsight.

This is also, frankly, the case for doing it with a distributor beside you. Not for the fund selection — for the phone call in the crash. We have made those calls since 2014 (ARN-145870), and they have added more to client outcomes than any scheme we ever shortlisted.

A last practical note on reaching the milestone: the crore is not a finish line where the money should suddenly go to sleep in a savings account. Investors who arrive there usually transition the corpus in stages — trimming equity exposure as the goal date approaches, moving matured slices into steadier hybrid or debt categories, and, if the goal is income, drawing from it through a Systematic Withdrawal Plan rather than redeeming everything at once. Deciding that glide path in year twelve, not year fifteen, is what separates a planned outcome from a lucky one.
