SIP for 1 Crore in 15 Years: Monthly Investment Estimate
A 15-year 1 crore target is more manageable than a 10-year target because compounding has five extra years to work.
Quick estimate
At a smooth 12% annual return assumption with beginning-of-month contributions, the required SIP for 1 crore in 15 years is roughly ₹19,800 per month. A more conservative return assumption needs a higher monthly contribution.
| Assumed annual return | Approximate monthly SIP | Investment period |
|---|---|---|
| 8% | ₹29,000 | 15 years |
| 10% | ₹24,200 | 15 years |
| 12% | ₹19,800 | 15 years |
| 14% | ₹16,300 | 15 years |
Formula used
The calculation uses the standard future value of a recurring investment: FV = SIP x [((1 + r)^n - 1) / r] x (1 + r). It assumes monthly contributions and a constant monthly return derived from the annual scenario.
Worked example at 12%
For 15 years, there are 180 monthly SIP instalments. With a 12% annual planning assumption, the estimated monthly SIP needed for a 1 crore future value is around ₹19,800.
Inflation check
1 crore after 15 years will not have the same purchasing power as 1 crore today. At 6% inflation, a goal costing 1 crore today may need roughly 2.4 crore after 15 years. For real planning, calculate the inflation-adjusted target first.
Step-up SIP option
If you cannot start at the full required amount, a step-up SIP can help. For example, start lower and increase the SIP every year as income rises. The final result depends on the annual increase and whether the increases are actually continued.
Risk reminders
Equity mutual funds can underperform for long periods. Do not treat a calculator result as a promise. Keep emergency savings separate and shift money gradually to lower-risk assets when the goal gets closer.
