Discover how to compute Net Asset Value (NAV) in Systematic Investment Plans (SIPs) to monitor your investments and make informed financial decisions effectively.

Systematic Investment Plans (SIPs) have gained popularity among individuals aiming to grow wealth systematically. By allowing fixed contributions at regular intervals, SIPs offer a disciplined approach to mutual fund investments. Understanding the calculation of Net Asset Value (NAV) in SIPs is vital for accurately tracking investment performance.

Calculating NAV in SIPs

Net Asset Value (NAV) denotes the per-unit market value of a mutual fund scheme, determined by dividing the total fund assets by outstanding units. In SIPs, where fixed contributions are made periodically, NAV calculation considers cumulative contributions.

  1. Information Gathering: Begin by assembling pertinent data, including the total fund assets and outstanding units.
  2. Total Contribution Calculation: Determine the overall SIP investment by multiplying the periodic amount by the number of contributions.
  3. Total Units Purchased: Divide the total investment by the NAV at each contribution to ascertain the units acquired.
  4. Current NAV Determination: Calculate the present NAV by dividing the total fund assets by outstanding units.
  5. Investment Performance Evaluation: Compare the initial NAV to the current NAV to evaluate SIP performance. Higher NAV suggests potential appreciation, while lower NAV indicates a possible decline.

Example of NAV Calculation in SIP

Let’s illustrate the calculation of Net Asset Value (NAV) in a Systematic Investment Plan (SIP) with a practical example:

Suppose an investor initiates a SIP with a monthly contribution of ₹500 for 12 months. The NAV of the mutual fund at the time of the first contribution is ₹20. Here’s how the NAV calculation unfolds:

  1. Total Contribution: The total contribution over 12 months is calculated as:

Total Contribution = ₹500 * 12 = ₹6,000

  1. Total Units Purchased: Next, we determine the total number of units purchased based on the total contribution and the NAV at the time of investment:

Total Units Purchased = ₹6,000 / ₹20 = 300 units

  1. Current NAV: Finally, to calculate the current NAV, we need to consider the total fund assets and outstanding units. Assuming no change in the total fund assets, we use the formula:

Current NAV = Total Fund Assets / Outstanding Units

Since we’ve invested for 12 months, let’s assume the total fund assets have grown to ₹7,000. Therefore, the current NAV would be: 

Current NAV = ₹7,000 / 300 units = ₹23.33 per unit

In this example, the investor has accumulated 300 units of the mutual fund through their SIP contributions. The current NAV of the mutual fund, based on the increased total fund assets, is calculated to be ₹23.33 per unit. This demonstrates how NAV is computed in SIPs and highlights its importance in evaluating investment performance over time.
