When you invest through a Systematic Investment Plan, you are putting money into a mutual fund at regular intervals. Most investors focus on the amount they invest and the returns they expect. But there is another element that plays a role in this process.
That element is the net asset value.
It may look like just a number, but it affects how your investment behaves over time. Understanding this connection helps you see your SIP more clearly.
What is net asset value?
The net asset value is the price of one unit of a mutual fund.
It is calculated by taking the total value of the fund’s investments, subtracting expenses, and dividing it by the number of units.
In simple terms, the net asset value tells you how much one unit of the fund is worth on a given day.
This value changes daily because the underlying investments change in value.
How a Systematic Investment Plan works with NAV
When you invest through a Systematic Investment Plan, you buy units of a mutual fund regularly.
Each time you invest:
- the amount you invest is divided by the net asset value
- you receive units based on that value
For example:
- if the net asset value is lower, you get more units
- if the net asset value is higher, you get fewer units
This process happens automatically with every instalment.
Why NAV movement matters in SIP
The net asset value keeps changing with market conditions.
In a rising market:
- NAV increases
- you receive fewer units for the same amount
In a falling market:
- NAV decreases
- you receive more units
This difference may seem small at first, but over time it plays a role in how your investment builds.
The concept of averaging
One of the key features of a Systematic Investment Plan is averaging.
Since you invest at different NAV levels:
- you buy more units when prices are lower
- you buy fewer units when prices are higher
This spreads your investment across different market conditions.
The net asset value is what makes this averaging possible.
Why lower NAV does not mean a better fund
A common misunderstanding is that a fund with a lower net asset value is cheaper or better.
This is not correct.
NAV only reflects the current value of the fund. It does not indicate quality or future performance.
For example:
- a fund with a higher NAV is not necessarily expensive
- a fund with a lower NAV is not necessarily a better option
What matters is how the fund performs over time.
SIP and long-term impact of NAV
Over a long period, the impact of net asset value becomes clearer.
Since you invest regularly:
- you collect units at different NAV levels
- your total units build gradually
When the NAV rises over time, the value of all your accumulated units increases.
So your final investment value depends on:
- the number of units you hold
- the NAV at the time of redemption
Behaviour during market changes
Many investors react to NAV changes.
When NAV falls, it may create concern. When it rises, it may create confidence.
But in a Systematic Investment Plan, both situations play a role.
Lower NAV helps you accumulate more units. Higher NAV increases the value of the units you already hold.
So instead of reacting to short-term changes, it helps to focus on consistency.
Timing versus consistency
Some investors try to time their SIP based on NAV levels.
They may think:
- investing only when NAV is low is better
- avoiding investment when NAV is high will improve returns
But this approach goes against the idea of a Systematic Investment Plan.
SIP is designed to remove the need for timing.
By investing regularly, you automatically adjust to different NAV levels.
NAV and market cycles
Markets move in cycles. NAV reflects these movements.
During a full cycle:
- there will be periods of low NAV
- there will be periods of high NAV
A Systematic Investment Plan works across these cycles.
It does not depend on predicting the right time. It builds gradually across different phases.
Common mistakes related to NAV
Some common mistakes include:
- focusing only on current NAV instead of long-term performance
- assuming lower NAV means better value
- trying to stop or start SIP based on NAV changes
These can affect the overall investment approach.
Understanding the role of net asset value helps avoid these mistakes.
A simple way to understand it
You can think of net asset value as the price at which you buy units.
A Systematic Investment Plan uses this price to determine how many units you get each time.
Over time:
- your units increase
- the value of those units depends on NAV movement
So both the number of units and the NAV matter together.
