What is SIP?

SIP (Systematic Investment Plan) is a way to invest a fixed amount at regular intervals—typically every month—in a mutual fund of your choice. Instead of investing a large lump sum at once, you commit to a smaller amount each month, which is debited automatically from your bank account and used to buy units of the fund at the prevailing Net Asset Value (NAV). In India, SIPs have become one of the most popular ways to invest in equity and debt mutual funds, with many investors starting with as little as ₹500 per month.

SIP encourages discipline and rupee cost averaging. Because you invest the same amount every month, you automatically buy more units when the market is down and fewer when it is up. Over time, this can smooth out the average purchase price and reduce the impact of timing the market. It also removes the need to decide each month whether to invest; the mandate does the work for you. For long-term goals such as retirement, children's education, or building an emergency corpus, a SIP in a well-chosen mutual fund can help you benefit from compounding over many years.

Returns from a SIP are not guaranteed. Mutual funds are market-linked, and past performance does not indicate future results. However, using a SIP calculator helps you set realistic expectations: you can see how much you would invest in total over a given period and what the maturity amount might be if the fund delivers a certain average annual return. The calculator above uses the standard future value of annuity formula (with payments at the beginning of each month) so you can plan your SIP amount and tenure before you start or adjust an existing SIP.

How is SIP maturity calculated?

The maturity value of a SIP is the future value of a series of equal payments (your monthly investment) that grow at a fixed rate of return. Because SIPs are usually set up with the payment at the beginning of each month (advance annuity), the formula accounts for one extra month of compounding for each payment. The future value of a monthly SIP (payments at the start of each month) is:

• P = Monthly investment (SIP amount in rupees)
• r = Monthly rate of return (annual rate ÷ 12 ÷ 100; e.g. 12% p.a. gives r = 0.01)
• n = Number of months (e.g. 20 years = 240 months)

The calculator uses this formula so the result matches the standard method used by fund houses and financial planners. The "wealth gain" shown is simply FV minus the total amount you invested (P × n).

Example: ₹10,000/month, 12% return, 20 years

Suppose you start a SIP of ₹10,000 per month in an equity-oriented fund and assume an average annual return of 12% over 20 years. Your total investment over the period is ₹10,000 × 240 months = ₹24,00,000. Using the future value of annuity formula (with monthly rate r = 0.01 and n = 240), the estimated maturity value comes to approximately ₹99 lakh. The wealth gain—the amount your money has grown by—is about ₹75 lakh, which is over three times what you put in. This illustrates the power of compounding and long-term SIP investing. Remember, 12% is only an assumption; actual returns will vary. Use the calculator above with your own SIP amount, expected return, and tenure to see different scenarios, such as a higher monthly SIP or a longer time horizon.

Benefits of Using This Calculator

A SIP calculator helps you set a realistic monthly investment amount and see how much your corpus could grow over time at a given expected return. Before you start a SIP or increase your existing one, you can enter different amounts and tenures to find a combination that fits your budget and goal. The calculator shows total invested versus estimated maturity, so you clearly see the effect of compounding and the importance of starting early and staying invested.

You can use it to plan for specific goals—for example, how much to SIP for 15 years to target a certain retirement corpus, or how a ₹15,000 monthly SIP compares with ₹10,000 over 20 years. It also helps you compare different return assumptions: using a conservative rate (e.g. 10%) versus a higher one (e.g. 12%) shows the range of outcomes and reminds you that returns are not guaranteed. The result is a clear, numeric target to work toward and a better understanding of how SIPs can support long-term wealth creation in India.

How to Use This Calculator

Using the SIP calculator is simple. First, enter your monthly SIP amount in rupees—the amount you plan to invest every month (e.g. ₹5,000, ₹10,000, or ₹25,000). Second, enter the expected annual return as a percentage. For equity funds, investors often assume 10–12% for long-term planning; for debt or hybrid funds, use a lower rate. Third, set the investment tenure in years or months (e.g. 10, 15, or 20 years). The calculator will show your total invested amount, the estimated maturity value, and the wealth gain.

You can change any input and see the results update immediately. Try increasing the SIP amount or the tenure to see how much more you could accumulate. Use a conservative return assumption so you are not disappointed if actual returns are lower. The results are for estimation and planning only; actual mutual fund returns depend on market performance and will vary. For tax implications (e.g. LTCG on equity, taxation of debt funds), refer to current rules or a tax advisor.
