What is a Systematic Investment Plan (SIP)?

A Systematic Investment Plan (SIP) is a highly disciplined financial strategy where an individual invests a fixed sum of money at regular intervals—typically monthly—into a chosen asset class like mutual funds or index funds. Instead of trying to time the volatile stock market with a lump sum, a SIP averages out your purchase cost over time. This approach significantly lowers market risk while maximizing the long-term benefits of compounding.

How Does Compound Interest Work?

If simple interest is a straight line, compound interest is a snowball rolling down a massive hill. When you invest money, it generates a return. In a compounding system, those returns are reinvested automatically. In your second year, you are earning returns not just on your initial cash, but on the returns from year one. The longer you leave the money untouched, the more explosive the exponential growth becomes.

Frequently Asked Questions

What is a good expected return rate to enter?

Historically, broad market index funds (like the S&P 500) have returned an average of 9% to 10% annually over long periods, before adjusting for inflation. If you are investing in conservative bonds, you might want to lower the rate to 4% or 5%. Always remember that past performance does not guarantee future results.

Does inflation affect my maturity value?

Yes. The total maturity value shown in this calculator is a "nominal" figure, meaning it does not account for the future loss of purchasing power due to inflation. To calculate real returns, you can subtract the average inflation rate (usually 2-3%) from your expected annual return rate before calculating.
