Understand How the SIP Calculator Works - Systematic Investment Planning

What is a SIP Calculator?

The SIP Calculator is an online tool that helps investors estimate the future value of their Systematic Investment Plan (SIP) investments. An SIP allows you to invest a fixed amount regularly (monthly or quarterly) in mutual funds, enabling disciplined wealth creation over time. This calculator provides a clear projection of your total invested amount, estimated returns, and final value based on your monthly investment, expected annual return rate, and investment duration. It’s an essential tool for financial planning, helping you achieve goals like buying a house, funding education, or planning for retirement.

How Does the SIP Calculator Work?

The SIP Calculator works by calculating the future value of your monthly investments under compound interest, assuming a fixed monthly investment and a constant expected return rate. It takes the following inputs:

• Monthly Investment: The amount you invest each month (e.g., ₹25,000).
• Expected Return Rate (p.a.): The annual rate of return you expect from your investment (e.g., 12%). This is converted to a monthly rate for calculation.
• Time Period: The duration of your investment in years (e.g., 10 years).

The calculator uses the following mathematical formula to compute the future value (\( A \)) of your SIP:

\( A = P \times \left( \frac{(1 + r)^n - 1}{r} \right) \times (1 + r) \)

Where:

• \( A \): Future Value (Total Value at the end of the investment period)
• \( P \): Monthly Investment (e.g., ₹25,000)
• \( r \): Monthly interest rate = Annual rate / 12 (e.g., 12% / 12 = 1% = 0.01)
• \( n \): Total number of months = Time Period × 12 (e.g., 10 years × 12 = 120 months)

The calculator then computes:

• Invested Amount: Total amount invested over the period (Monthly Investment × Total Months).
• Estimated Returns: The profit earned on your investment (Future Value - Invested Amount).
• Total Value: The final value of your investment (Future Value).

The calculator assumes:

• The investor deposits the same amount every month.
• Deposits are made on the 1st of each month, and the return rate compounds monthly.
• No withdrawals are made during the investment period.

Example Calculation

Let’s calculate the future value of an SIP with the following inputs:

• Monthly Investment: ₹25,000
• Expected Return Rate (p.a.): 12%
• Time Period: 10 years

Step 1: Calculate Total Months and Monthly Rate

Total Months = \( 10 \times 12 = 120 \)

Monthly Rate (\( r \)) = \( 12\% / 12 = 1\% = 0.01 \)

Step 2: Compute Total Invested Amount

Invested Amount = \( 25,000 \times 120 = 30,00,000 \)

Step 3: Compute Future Value

\[ A = 25,000 \times \left( \frac{(1 + 0.01)^{120} - 1}{0.01} \right) \times (1 + 0.01) \]

\[ (1 + 0.01)^{120} = 1.01^{120} \approx 3.300386 \]

\[ \frac{(3.300386 - 1)}{0.01} \approx 230.0386 \]

\[ A = 25,000 \times 230.0386 \times 1.01 \approx 58,08,475 \]

Step 4: Compute Estimated Returns

Estimated Returns = \( 58,08,475 - 30,00,000 = 28,08,475 \)

Results:

• Invested Amount: ₹30,00,000
• Estimated Returns: ₹28,08,475
• Total Value: ₹58,08,475

The SIP Calculator performs these steps automatically and displays the results instantly as you adjust the inputs.
