SIP Calculator 2026: How Much to Invest Monthly for Crorepati Goals
July 2026 · 10 min read
Systematic Investment Plans or SIPs are the most disciplined way to build wealth in the Indian stock market through mutual funds. Instead of trying to time the market, you invest a fixed amount every month regardless of market conditions. This strategy, called rupee-cost averaging, ensures you buy more units when markets are low and fewer when markets are high, averaging out your entry price over time.
A SIP calculator helps you estimate the future value of your monthly investments based on expected returns. Whether you are saving for a child's education, a house down payment, or early retirement, knowing how much to invest each month is the first step toward achieving your goal.
How SIP Works in Mutual Funds
When you start a SIP, a fixed amount is automatically debited from your bank account and invested in the mutual fund scheme of your choice on a specific date each month. You receive units at the prevailing Net Asset Value (NAV). Over time, this approach reduces the impact of market volatility and eliminates the need to time your entry.
Rupee-Cost Averaging in Action
Suppose you invest Rs 10,000 every month in an equity mutual fund. In Month 1, the NAV is Rs 100, so you get 100 units. In Month 2, the NAV drops to Rs 80, so you get 125 units. Your average cost per unit is not Rs 90 but Rs 88.89 because you bought more units at the lower price. This built-in averaging is the biggest advantage of SIPs over lump sum investments.
SIP Returns: What to Expect in 2026
Historical returns of Indian equity mutual funds over 10-15 year periods have ranged between 12% and 15% per annum. For conservative planning, use 12% for equity funds, 8-9% for hybrid funds, and 6-7% for debt funds. Your actual returns will depend on the fund's performance, market conditions, and the tenure of your investment.

| Monthly SIP | Duration | Total Invested | Est. Returns | Total Value |
|---|---|---|---|---|
| Rs 5,000 | 10 years | Rs 6,00,000 | Rs 4,63,000 | Rs 11,63,000 |
| Rs 10,000 | 15 years | Rs 18,00,000 | Rs 24,10,000 | Rs 50,10,000 |
| Rs 25,000 | 20 years | Rs 60,00,000 | Rs 1,87,00,000 | Rs 2,47,00,000 |
| Rs 50,000 | 25 years | Rs 1,50,00,000 | Rs 7,16,00,000 | Rs 8,66,00,000 |
Goal-Based SIP Planning
Instead of asking "how much should I invest," start with your financial goal and work backward using the SIP calculator.
Example 1: Rs 1 Crore Retirement Corpus
If you want Rs 1 crore by age 55 and you are 30 today (25 years), you need to invest approximately Rs 10,000 per month in an equity fund assuming 12% annual returns. If you delay starting by just 5 years (age 35), the monthly SIP needed jumps to about Rs 22,000.
Example 2: Child's Education Fund
Suppose your child is 5 years old and you need Rs 50 lakhs for higher education when they turn 18. With a 13-year horizon, investing Rs 22,000 per month at 12% returns could get you there. If you wait until the child is 10, the monthly SIP doubles to Rs 44,000.
Power of Compounding in SIP
Compounding is what makes SIP investing truly powerful. Your returns start earning returns of their own, creating a snowball effect over long periods. The earlier you start, the more dramatic this effect becomes.
Consider two investors: Anika starts a Rs 10,000 monthly SIP at age 25 and stops at 35, investing a total of Rs 12 lakhs over 10 years. She lets the corpus grow until age 60. Bharat starts the same Rs 10,000 SIP at age 35 and continues until 60, investing Rs 30 lakhs over 25 years. Despite investing 2.5 times more, Bharat's final corpus is smaller because Anika's money had 25 extra years to compound.
This is why financial advisors across India emphasise starting early, even with smaller amounts.
Step-Up SIP: Increase Investments Over Time
A step-up SIP allows you to increase your monthly contribution every year, typically in line with your salary growth. For example, start with Rs 10,000 per month and increase by 10% every year. In 20 years, your final corpus would be approximately 40% higher than a flat Rs 10,000 SIP.

Tax Benefits of SIP Investments
SIPs in Equity Linked Savings Scheme (ELSS) mutual funds qualify for tax deduction up to Rs 1,50,000 under Section 80C of the Income Tax Act. ELSS funds also have the shortest lock-in period among all Section 80C options, just 3 years. SIPs in regular equity mutual funds are subject to long-term capital gains tax of 10% on gains above Rs 1 lakh per year.
Common SIP Mistakes to Avoid
- Stopping SIP during market falls: This defeats rupee-cost averaging. Continue your SIP when markets are down to buy more units at lower NAV.
- Not reviewing fund performance: Check your fund's performance against its benchmark every 6-12 months. Switch if underperformance persists for 3+ consecutive years.
- Investing without a goal: A SIP without a clear goal leads to premature withdrawals and suboptimal returns. Define what you are saving for.
- Ignoring expense ratios: Higher expense ratios eat into your returns. Choose direct plans over regular plans to save 0.5-1% annually.
- Using short-term debt funds for SIP: Debt funds suit lump sum investments better. SIPs work best with equity and hybrid funds over long periods.
Frequently Asked Questions
What is the minimum amount for SIP in India?
Most mutual funds allow SIP starting from Rs 500 per month. Some funds have higher minimums of Rs 1,000 or Rs 5,000. You can start with as little as Rs 500 and increase over time with a step-up SIP.
Can I lose money in SIP?
Yes, SIPs in equity funds are subject to market risk. Your investment value can go down in the short term. However, over periods of 7-10 years or more, equity SIPs have historically delivered positive returns. The risk of loss reduces significantly with longer holding periods.
Which is better: SIP or lump sum investment?
SIP is better for regular investors who want to build wealth gradually without timing the market. Lump sum works better when you have a large amount and markets are at attractive valuation levels. For most salaried individuals, SIP is the recommended approach for long-term wealth creation.
How is SIP return calculated?
SIP returns are calculated using the Extended Internal Rate of Return (XIRR) method, which accounts for each monthly investment having a different holding period. Our SIP calculator uses this method to give you accurate projections based on your investment amount and expected returns.
