What is a Systematic Investment Plan (SIP)?

A Systematic Investment Plan, popularly known as SIP, is a method of investing a fixed sum of money regularly in mutual funds. Instead of making a one-time lump sum investment, SIP allows you to invest small amounts at pre-defined intervals (monthly, quarterly, or half-yearly).

How Does SIP Work?

When you invest via SIP, you buy a certain number of units of a mutual fund scheme. Because the market fluctuates, you buy more units when prices are low and fewer units when prices are high. This process is known as Rupee Cost Averaging, which helps in lowering the average cost of your investment over time.

The Power of Compounding

The primary benefit of SIP is compounding. Compounding occurs when the returns generated from your investment are reinvested to earn even more returns. Over a long period, even small monthly contributions can grow into a substantial wealth corpus. For example, investing $500 monthly for 20 years at a 12% annual return results in a total value significantly higher than the principal amount invested.

SIP Calculation Formula

The SIP calculator uses the following mathematical formula:

FV = P × [((1 + i)n – 1) / i] × (1 + i)

  • FV: Future Value of the investment.
  • P: Monthly Investment amount.
  • i: Monthly rate of interest (Annual rate / 12 / 100).
  • n: Total number of monthly installments.

Example Calculation

Suppose you invest $1,000 per month for 5 years at an expected annual return of 10%.

  • Total Amount Invested: $60,000
  • Estimated Returns: $17,442
  • Total Value: $77,442

By starting early and staying disciplined, you can achieve your long-term financial goals through the simplicity of SIP.
