Daily SIPs and monthly SIPs both invest in a mutual fund at regular intervals. The difference lies in how often the investment occurs. A monthly SIP invests the chosen amount once a month, while a daily SIP spreads the investment across multiple days. That changes the timing of the purchases, but it does not change the mutual fund itself.
For some investors, making smaller investments more often may feel convenient. For others, setting aside a fixed amount each month is much easier to manage.
This article looks at how daily and monthly SIPs work, where they differ, whether investing more frequently can affect returns, and what to consider before choosing between the two.
Key Takeaways
- A monthly SIP makes a single investment once a month, while a daily SIP spreads smaller instalments across active market trading days (~20–22 days/month).
- Monthly SIPs align seamlessly with monthly salary cycles, whereas daily SIPs require constant bank liquidity to avoid auto-debit failures.
- While AMCs do not penalize failed transactions, commercial banks charge bounce fees (often ₹250–₹500 + GST) if a daily debit fails due to an insufficient account balance.
- A daily SIP generates around 240–250 passbook entries per year compared to just 12 entries for a monthly SIP, making bank statements significantly busier.
- Higher investment frequency does not guarantee better returns; long-term wealth creation depends far more on total amount invested, market tenure, and consistency.
What is a Daily SIP?
A daily SIP is a systematic investment plan in which a fixed amount is invested in a mutual fund on a daily basis.
For example, an investor may decide to invest ₹500 through a daily SIP. Instead of making a single larger investment at the beginning or end of the month, the money is invested in smaller amounts on the applicable investment days.
The number of actual investments in a month can vary because mutual fund transactions depend on the applicable business days and the scheme's terms.
The idea behind a daily SIP is quite simple. The investment is spread across multiple dates rather than made in a single monthly transaction.
What is a Monthly SIP?
A monthly SIP means investing a fixed amount in a mutual fund once every month.
An investor could, for example, choose a ₹5,000 monthly SIP and select an available date for the investment.
The amount is then invested according to the SIP instructions and applicable scheme terms.
Monthly SIPs are often convenient for people whose income also comes in monthly. A fixed amount can be kept aside every month without having to plan for multiple investments during the month.

How Does a Daily SIP Work?
Take an investor who wants to invest ₹6,000 per month.
With a monthly SIP, the full ₹6,000 may be invested on the selected SIP date.
With a daily SIP, the same investment can be divided into smaller amounts and invested across the applicable days.
The investor will therefore purchase units at different NAVs during the month.
This matters because the NAV of a mutual fund can change from one day to another. A fixed amount buys more units when the NAV is lower, and fewer units when the NAV is higher.
The daily SIP simply creates more such purchase points.
How Does a Monthly SIP Work?
A monthly SIP follows the same basic principle, but there is one investment during the month.
Suppose ₹6,000 is invested through a monthly SIP.
If the applicable NAV on the investment date is ₹30, the investment would purchase 200 units, before considering any applicable factors.
If the NAV falls to ₹25 the following month, the same ₹6,000 would purchase 240 units.
The number of units purchased changes with the NAV. Over a longer period, the investor ends up buying units at different prices as the NAV moves.
Factors to Consider Before Choosing a Daily SIP
While spreading investments daily sounds appealing, daily SIPs come with specific operational and administrative aspects that investors should keep in mind:
1. Risk of Bank Auto-Debit Bounce Fees
-
AMC Policy: Asset Management Companies (AMCs) do not charge any penalty or fee if a daily SIP auto-debit fails due to insufficient account balance.
-
Commercial Bank Charges: However, commercial banks typically treat a failed SIP auto-debit as an auto-debit/NACH bounce. Banks usually charge a penalty fee (often ranging from ₹250 to ₹500 plus applicable taxes) for every failed debit instruction.
-
Impact of High Frequency: Because a daily SIP triggers 20 to 22 auto-debit attempts every month, maintaining a low account balance can lead to multiple bank penalty charges in a short period.
2. Administrative Impact on Bank Statements
-
Volume of Entries: A monthly SIP creates 12 line items in a bank statement or passbook per year. A daily SIP generates approximately 240 to 250 line items per year.
-
Passbook Tracking: For individuals who closely track their accounts or reconcile transactions for accounting and tax preparation, managing many micro-debits can make bank statements noticeably harder to read.
Does Daily SIP Give Better Returns?
A daily SIP provides more investment dates, but more frequent investing does not automatically translate into higher returns.
The outcome depends on what happens to the mutual fund's NAV over the investment period.
Suppose the NAV rises steadily throughout a particular month. An investment made earlier in that month could benefit from the lower starting NAV. In a different month, the market could fall and the outcome could be different.
This makes it difficult to say that daily SIPs will always perform better than monthly SIPs.
For long-term investors, the amount invested and the period for which the SIP continues may matter considerably more than whether the investment is made every day or once a month.
Daily SIP and Rupee Cost Averaging
One of the ideas associated with SIP investing is rupee cost averaging. A fixed amount buys different quantities of units depending on the NAV.
For example:
|
NAV |
Investment |
Units purchased |
|
₹50 |
₹500 |
10 |
|
₹40 |
₹500 |
12.5 |
|
₹25 |
₹500 |
20 |
At ₹50, ₹500 buys 10 units. When the NAV falls to ₹25, the same ₹500 buys 20 units.
This happens because the investment amount stays fixed while the NAV changes.
Both daily and monthly SIPs follow this principle. The difference is that a daily SIP creates more purchase dates within a month.
Rupee cost averaging, however, should not be taken as protection against losses. If the underlying mutual fund falls in value, the investment can still lose money.

Daily SIP vs Monthly SIP: An Example
Consider an investor who wants to invest ₹12,000 during a month.
With a monthly SIP, ₹12,000 could be invested on the selected SIP date.
With a daily SIP, the ₹12,000 can be divided into smaller amounts and invested across applicable investment dates.
Now assume the fund's NAV moves between ₹90, ₹95, ₹88 and ₹100 during the month.
The daily SIP will make purchases at several of these NAV levels, depending on the investment dates.
The monthly SIP will buy units at the NAV applicable on its selected date.
Which approach works out better depends on the actual sequence of NAV movements. There is no fixed answer in advance.
Does SIP Frequency Matter Over the Long Term?
It can make a difference to the timing of individual purchases, but frequency should not be viewed in isolation. For a long-term investor, other factors can have a much greater bearing on the eventual investment value.
These include the amount invested regularly, how long the SIP continues, the performance of the chosen mutual fund and whether the investor remains invested during different market conditions. A monthly SIP that continues for many years can be more useful than a daily SIP that is repeatedly stopped.
Daily SIP vs Monthly SIP: Which is Better for a New Investor?
For someone starting a SIP, a monthly option can be easier to understand and manage.
The investor decides on an amount, selects an available date and makes sure that the required money is available every month.
Daily SIPs can also be used, provided the facility is available and the investor is comfortable with the frequency and keeping a sufficient balance buffer in their account to avoid bank bounce fees.
There is no rule that a new investor has to start with a daily SIP to get the benefits of regular investing.

Conclusion
Daily SIPs and monthly SIPs follow the same basic idea of investing regularly in a mutual fund. The difference lies in the frequency of the investments. A daily SIP spreads purchases across multiple investment dates, while a monthly SIP makes the investment once during the selected month. This changes the timing of unit purchases, but it does not change the underlying mutual fund.
Neither option guarantees better returns. For most investors, the practical choice comes down to income pattern, investment amount, convenience, and ease of bank balance management. A SIP that can be maintained regularly over the intended investment period is often more important than choosing between daily and monthly frequency.
