How Much SIP is Required to Build a ₹1 Crore Corpus?
5 Min Read · Written by WealthTools Team
Saving ₹1 Crore is a landmark target for most Indian investors, often representing financial independence or a significant retirement milestone. While the number sounds huge, building this corpus is completely achievable through disciplined, monthly mutual fund SIPs.
Let's break down the exact monthly SIP amounts required to hit this target across different time horizons, assuming a standard equity return rate of 12% per year.
Monthly SIP Needed to Reach ₹1 Crore (at 12% returns)
| Time Period (Years) | Monthly SIP Amount | Total Invested Amount | Estimated Interest Earned |
|---|---|---|---|
| 10 Years | ₹43,040 / month | ₹51.6 Lakhs | ₹48.4 Lakhs |
| 15 Years | ₹19,770 / month | ₹35.6 Lakhs | ₹64.4 Lakhs |
| 20 Years | ₹10,010 / month | ₹24.0 Lakhs | ₹76.0 Lakhs |
| 25 Years | ₹5,270 / month | ₹15.8 Lakhs | ₹84.2 Lakhs |
The Famous 15-15-15 Rule of Compounding
In mutual fund investing, there is a popular thumb rule to understand the power of compound interest:
"Invest ₹15,000 every month for 15 years in an equity fund that returns an average of 15% annually. By the end of 15 years, you will accumulate exactly ₹1 Crore."
Under the 15-15-15 rule, you invest a total of **₹27 Lakhs** over 15 years. The interest accumulated is **₹73 Lakhs**, bringing your total final portfolio value to **₹1 Crore**. This shows how compounding grows your capital exponentially over time.
How to Reach Your ₹1 Crore Goal Faster
If a monthly investment of ₹19,000 is too high for your current budget, here are two simple adjustments:
- Extend the tenure: By increasing the investment duration from 15 to 20 years, your required monthly SIP drops by almost 50%—to just ₹10,010/month.
- Use the Step-Up strategy: Start with a smaller monthly SIP (e.g., ₹8,000) and increase it by 10% every year. As your income increases, your SIP increases automatically, allowing you to reach ₹1 Crore in the same timeframe with a lower starting budget.
