Free SIP Calculator – Calculate Mutual Fund SIP Returns Online
By RapidTool Team · Last updated: September 2026
A Systematic Investment Plan (SIP) allows you to invest a fixed amount in mutual funds every month. Over time, SIP creates significant wealth through the power of compounding and rupee-cost averaging. Our free SIP calculator instantly shows how much your monthly investment will grow, including an advanced step-up SIP feature.
What Is Step-Up SIP?
Step-up SIP (also called top-up SIP) means increasing your monthly SIP amount by a fixed percentage each year — typically matching your annual salary increment. For example, starting with ₹5,000/month and stepping up 10% annually means ₹5,500 in year 2, ₹6,050 in year 3, and ₹11,789 by year 10. Step-up SIP dramatically increases your final corpus compared to a flat SIP because you invest more as your income grows.
Example: ₹5,000/month SIP at 12% for 20 years = ₹49.96 lakh corpus. With 10% annual step-up, the same starting SIP becomes ₹1.09 crore — over 2× more wealth!
SIP Formula
SIP Corpus = P × {[(1 + r)ⁿ − 1] ÷ r} × (1 + r), where P = Monthly SIP amount, r = Monthly rate of return (Annual Rate ÷ 12 ÷ 100), n = Total months (Years × 12). Our calculator applies this formula month by month, including step-up increases at each year boundary.
How Much SIP Is Needed to Reach ₹1 Crore?
At 12% annual returns: ₹43,500/month for 10 years, ₹19,800/month for 15 years, or ₹10,000/month for 20 years. The longer you stay invested, the less you need to contribute each month — which is why starting early is the most powerful financial decision you can make.
Frequently Asked Questions
What is SIP in mutual funds and how does it work?
SIP is a disciplined way to invest a fixed amount in mutual funds at regular monthly intervals. Each month, your SIP auto-debits from your bank account and buys mutual fund units at the current NAV (Net Asset Value). When NAV is low, you get more units; when high, fewer units — this averages your purchase price over time (rupee-cost averaging) and reduces the impact of market volatility.
What is the minimum SIP amount in India?
Most mutual funds in India accept SIPs starting from ₹100–₹500 per month. Popular funds from SBI, HDFC, Axis, Mirae Asset, and Parag Parikh accept SIPs from ₹500/month. Some specialty or sectoral funds have higher minimums of ₹1,000–₹5,000/month. There is no upper limit on SIP amount.
Is SIP better than a lump sum investment?
Both strategies have merit depending on your situation. SIP is ideal for salaried investors who receive regular income and want to invest systematically without worrying about market timing. Lump sum investing works better when markets are significantly undervalued and you have a large idle amount. Many financial advisors recommend a hybrid approach — invest available lump sums and set up a SIP for ongoing income.
What annual return should I assume for SIP calculations?
For planning purposes, use these conservative estimates: large-cap equity funds 10–12%, diversified equity/flexi-cap funds 11–14%, mid-cap funds 12–15%, index funds tracking Nifty 50 10–12%, and debt funds 6–8%. Using 10–12% is considered a realistic and conservative assumption for long-term equity SIPs over 10+ years.
How is SIP different from RD (Recurring Deposit)?
Both involve regular monthly investments, but there are key differences. RD is a fixed-income product offered by banks with guaranteed returns (currently 5–7% p.a.). SIP invests in market-linked mutual funds with higher potential returns (10–15% historically) but no guarantee. RD is suitable for short-term, risk-free saving; SIP is better for long-term wealth creation above inflation.
