SIP Investment During A Market Crash: How A ₹25,000 Monthly Investment Can Buy More Mutual Fund Units
A sharp market decline can make mutual fund investors uneasy, especially when their portfolio starts showing negative returns. Yet a falling market can have a different impact on someone investing through a regular SIP. With a fixed amount going into the fund every month, lower NAVs allow the same investment to purchase more units. For investors with a long-term approach, this can help spread purchases across different market levels instead of relying on one entry point.
The calculation is straightforward: divide the SIP amount by the applicable NAV. When the NAV falls, the same amount of money buys a larger number of units.
Consider a monthly SIP of ₹25,000. If the fund's NAV is ₹100 when an instalment is invested, the amount buys 250 units.
Now imagine that the NAV falls to ₹80. The same ₹25,000 would purchase 312.50 units.
If the NAV drops further to ₹65, the investment would buy approximately 384.62 units.
This means that the number of units accumulated can rise significantly during a market decline, even though the monthly investment remains unchanged. At an NAV of ₹65, the same ₹25,000 buys around 50% more units than it did when the NAV was ₹100.
The example does not mean that a lower NAV automatically makes a mutual fund a better investment. It simply demonstrates how a fixed SIP amount translates into a different number of units as the NAV changes.
Under an SIP, the investor commits a predetermined amount at regular intervals rather than investing a different sum based on market movements. As a result, more units are purchased when the NAV is lower and fewer units are purchased when it is higher.
For example, the same ₹25,000 may buy 250 units at an NAV of ₹100, but 312.50 units at ₹80. The investment amount has not changed; only the price at which the units are acquired has moved.
Over multiple instalments, purchases therefore take place at different NAV levels. According to financial experts, this approach can reduce the dependence on trying to identify one supposedly perfect time to invest.
However, rupee cost averaging should not be confused with protection against losses. It changes the pattern of unit accumulation, but it does not eliminate market risk.
Suppose an investor accumulates additional units while the fund's NAV is lower. If the NAV later rises, those units may increase in value.
For instance, the units purchased at ₹65 would be worth more per unit if the NAV subsequently moved higher. The overall value of the SIP investment would then depend on the number of units accumulated and the fund's future NAV.
This is where the potential benefit of buying more units at lower levels becomes relevant for a long-term investor.
But there is no certainty that markets will recover within a particular period. A fund's NAV can remain under pressure for an extended period, fall further or fluctuate significantly before any sustained recovery.
Therefore, a market decline should not be treated as a guaranteed opportunity to make money.
An SIP takes a different route. The investor spreads purchases over several instalments, meaning units can be accumulated at multiple NAV levels.
When prices rise, the fixed contribution buys fewer units. When prices fall, it buys more.
This can be useful for investors who do not want to make their investment strategy dependent on accurately predicting short-term market movements. According to experts, attempting to consistently identify market bottoms and tops can be difficult, particularly for individual investors.
The SIP mechanism instead creates a disciplined investment schedule.
However, stopping an SIP during a decline also means giving up the opportunity to purchase units at those lower NAV levels.
If an investor's financial circumstances, investment objective and chosen mutual fund remain suitable, continuing the scheduled SIP can allow purchases to continue through both weak and strong market phases.
That does not mean every investor should continue every SIP regardless of circumstances. A fund may no longer match an investor's goals, risk tolerance or financial situation. Changes in income, liquidity requirements or investment objectives can also justify reviewing an SIP.
The important point is that a temporary market fall by itself does not necessarily mean that an existing SIP has stopped making sense.
That is not the case.
An SIP can accumulate additional units when NAVs are lower, but the eventual investment return depends on what happens to the value of those units in the future. If the NAV continues falling, the portfolio can remain under pressure despite the larger number of units.
Similarly, a recovery can improve the value of units bought at lower levels, but the timing and extent of any recovery cannot be predicted with certainty.
Mutual funds remain subject to market risks, and past performance or a particular investment strategy does not guarantee future returns.
That is the basic mathematics behind rupee cost averaging.
The strategy can help investors maintain a consistent investment habit without having to make repeated decisions about when the market is at its highest or lowest point. It also means that a period of falling prices is not necessarily harmful to someone who is continuing to accumulate units and has a suitable long-term investment horizon.
At the same time, investors should avoid viewing a market correction as a guaranteed route to higher profits. The fund's performance, future NAV movements, investment horizon and risk profile all remain important.
For investors who have chosen an SIP for long-term wealth creation, the key is to understand what happens to their money during both rising and falling markets. A lower NAV may increase the number of units purchased, but the eventual outcome still depends on how those investments perform over time.

How A ₹25,000 SIP Buys More Units
The number of mutual fund units purchased through an SIP depends on the fund's Net Asset Value, or NAV, on the relevant investment date.The calculation is straightforward: divide the SIP amount by the applicable NAV. When the NAV falls, the same amount of money buys a larger number of units.
Consider a monthly SIP of ₹25,000. If the fund's NAV is ₹100 when an instalment is invested, the amount buys 250 units.
Now imagine that the NAV falls to ₹80. The same ₹25,000 would purchase 312.50 units.
If the NAV drops further to ₹65, the investment would buy approximately 384.62 units.
This means that the number of units accumulated can rise significantly during a market decline, even though the monthly investment remains unchanged. At an NAV of ₹65, the same ₹25,000 buys around 50% more units than it did when the NAV was ₹100.
The example does not mean that a lower NAV automatically makes a mutual fund a better investment. It simply demonstrates how a fixed SIP amount translates into a different number of units as the NAV changes.
Why Rupee Cost Averaging Matters
This relationship between a fixed investment and changing prices is commonly associated with rupee cost averaging.Under an SIP, the investor commits a predetermined amount at regular intervals rather than investing a different sum based on market movements. As a result, more units are purchased when the NAV is lower and fewer units are purchased when it is higher.
For example, the same ₹25,000 may buy 250 units at an NAV of ₹100, but 312.50 units at ₹80. The investment amount has not changed; only the price at which the units are acquired has moved.
Over multiple instalments, purchases therefore take place at different NAV levels. According to financial experts, this approach can reduce the dependence on trying to identify one supposedly perfect time to invest.
However, rupee cost averaging should not be confused with protection against losses. It changes the pattern of unit accumulation, but it does not eliminate market risk.
What Happens To The Units During A Recovery?
A market decline is only one part of the investment cycle. What happens afterwards is equally important.Suppose an investor accumulates additional units while the fund's NAV is lower. If the NAV later rises, those units may increase in value.
For instance, the units purchased at ₹65 would be worth more per unit if the NAV subsequently moved higher. The overall value of the SIP investment would then depend on the number of units accumulated and the fund's future NAV.
This is where the potential benefit of buying more units at lower levels becomes relevant for a long-term investor.
But there is no certainty that markets will recover within a particular period. A fund's NAV can remain under pressure for an extended period, fall further or fluctuate significantly before any sustained recovery.
Therefore, a market decline should not be treated as a guaranteed opportunity to make money.
Why SIPs Work Differently From One-Time Investments
An investor making a lump-sum investment puts a larger amount into the market at one point in time. The NAV on that particular date therefore has a greater immediate influence on the number of units purchased.An SIP takes a different route. The investor spreads purchases over several instalments, meaning units can be accumulated at multiple NAV levels.
When prices rise, the fixed contribution buys fewer units. When prices fall, it buys more.
This can be useful for investors who do not want to make their investment strategy dependent on accurately predicting short-term market movements. According to experts, attempting to consistently identify market bottoms and tops can be difficult, particularly for individual investors.
The SIP mechanism instead creates a disciplined investment schedule.
Should You Stop Your SIP When The Market Falls?
A falling market can tempt investors to pause their SIPs because seeing a portfolio in the red can be uncomfortable.However, stopping an SIP during a decline also means giving up the opportunity to purchase units at those lower NAV levels.
If an investor's financial circumstances, investment objective and chosen mutual fund remain suitable, continuing the scheduled SIP can allow purchases to continue through both weak and strong market phases.
That does not mean every investor should continue every SIP regardless of circumstances. A fund may no longer match an investor's goals, risk tolerance or financial situation. Changes in income, liquidity requirements or investment objectives can also justify reviewing an SIP.
The important point is that a temporary market fall by itself does not necessarily mean that an existing SIP has stopped making sense.
More Units Do Not Automatically Mean Higher Returns
One common misunderstanding is that buying more units during a market decline automatically guarantees better returns.That is not the case.
An SIP can accumulate additional units when NAVs are lower, but the eventual investment return depends on what happens to the value of those units in the future. If the NAV continues falling, the portfolio can remain under pressure despite the larger number of units.
Similarly, a recovery can improve the value of units bought at lower levels, but the timing and extent of any recovery cannot be predicted with certainty.
Mutual funds remain subject to market risks, and past performance or a particular investment strategy does not guarantee future returns.
The Bigger Picture For SIP Investors
For a long-term SIP investor, market volatility can affect the number of units purchased at each instalment. A fixed ₹25,000 contribution buys fewer units when the NAV is high and more when the NAV is low.That is the basic mathematics behind rupee cost averaging.
The strategy can help investors maintain a consistent investment habit without having to make repeated decisions about when the market is at its highest or lowest point. It also means that a period of falling prices is not necessarily harmful to someone who is continuing to accumulate units and has a suitable long-term investment horizon.
At the same time, investors should avoid viewing a market correction as a guaranteed route to higher profits. The fund's performance, future NAV movements, investment horizon and risk profile all remain important.
For investors who have chosen an SIP for long-term wealth creation, the key is to understand what happens to their money during both rising and falling markets. A lower NAV may increase the number of units purchased, but the eventual outcome still depends on how those investments perform over time.
