SIP Calculator Guide: How Systematic Investment Plans Work
SIP is one of the most popular and powerful ways to build long-term wealth. Learn how compound growth works, what the formula calculates, and how to plan your investments.
What Is SIP?
A Systematic Investment Plan (SIP) lets you invest a fixed amount into a mutual fund at regular intervals — typically monthly. Rather than trying to time the market, SIP averages your purchase cost over time (rupee-cost averaging) and lets compounding do the heavy lifting.
SIPs are available from as little as ₹500 per month and work best as long-term, disciplined investments — ideally 5 to 30 years.
The SIP Formula
Worked Example
The Power of Compounding
The longer you invest, the more dramatic the compounding effect. Here's ₹5,000/month at 12% p.a.:
| Duration | Total Invested | Maturity Value | Wealth Gained |
|---|---|---|---|
| 5 years | ₹3,00,000 | ₹4,08,348 | ₹1,08,348 |
| 10 years | ₹6,00,000 | ₹11,61,695 | ₹5,61,695 |
| 15 years | ₹9,00,000 | ₹25,22,880 | ₹16,22,880 |
| 20 years | ₹12,00,000 | ₹49,95,740 | ₹37,95,740 |
| 30 years | ₹18,00,000 | ₹1,76,49,569 | ₹1,58,49,569 |
* Assumed 12% p.a. returns. Actual mutual fund returns vary. Past performance is not a guarantee of future returns.
Benefits of SIP
SIP vs. Lump Sum

| Minimum amount | ₹500/month | Often ₹1,000–₹5,000 one-time |
Frequently Asked Questions
What is the minimum SIP amount in India?
Most mutual funds allow SIPs starting from ₹500 per month. Some funds have even lower minimums of ₹100. There is no upper limit — you can invest as much as you want.
Can I stop a SIP anytime?
Yes. Most fund houses allow you to pause or stop a SIP without any penalty. You simply submit a cancellation request online through the AMC website or your broker. Existing units remain invested until you choose to redeem them.
Is SIP return guaranteed?
No. SIP returns depend on the performance of the underlying mutual fund, which is market-linked. Equity mutual funds have historically delivered 10–14% CAGR over long periods, but past performance is not a guarantee of future returns.
Is SIP tax-free in India?
SIP gains are taxable. For equity mutual funds, short-term capital gains (held less than 1 year) are taxed at 15%. Long-term capital gains (held over 1 year) above ₹1 lakh per year are taxed at 10%. ELSS SIPs qualify for ₹1.5 lakh deduction under Section 80C.
What is the best duration for a SIP?
Longer is better for equity SIPs. A 10+ year SIP allows compounding to work fully. Short SIPs of 1–3 years are vulnerable to market timing. Most financial advisors recommend a minimum of 5 years for equity fund SIPs.
What is the difference between SIP and lump sum investment?
SIP invests a fixed amount at regular intervals (monthly), averaging your purchase cost over time. Lump sum invests a large amount at once — better if markets are at a low point, but risky if you invest at a peak. SIP is generally safer for salaried investors.
