SIP Due Date
The SIP due date is the scheduled date on which each Systematic Investment Plan instalment is debited from your bank account and invested, with units allotted at the NAV applicable when funds reach the fund.
What Is the SIP Due Date?
The SIP due date (also called the SIP date) is the date you choose, at the time of SIP Registration, on which each instalment of your Systematic Investment Plan (SIP) is scheduled to be debited. For a monthly SIP on the 10th, the 10th of every month is the due date.
The due date decides when the money leaves your account. The NAV you get depends on when that money reaches the mutual fund relative to the cut-off time, so the debit date and the NAV date are not always the same.
Choosing a suitable due date is one of the simplest ways to avoid failed instalments and keep a SIP running smoothly.
How Does It Work?
- You select a date (and frequency) when registering the SIP. Available dates vary by AMC and platform; many offer a wide range of dates in a month.
- On the due date, the debit is presented to your bank through your mandate.
- Money moves to the mutual fund. AMFI's illustration of SIP settlement shows typical timelines (T = SIP date):
| SIP mode | Debit | Unit allotment |
|---|---|---|
| NACH (physical or e-NACH) | T | T |
| Bank auto-debit | T | T+1 |
| Internet SIP (bank-initiated) | T | T+1 |
- Applicable NAV: As per SEBI's rules, for schemes other than liquid and overnight funds, units are allotted at the NAV of the business day on which funds are available to the scheme before the 3:00 pm cut-off. AMFI notes that bank or payment-aggregator delays can push credit, and therefore allotment, to the next day. See Cut-Off Time and Applicable NAV.
- Non-business days: If the due date falls on a weekend or holiday, the debit and allotment usually happen on the next business day, depending on your AMC's and bank's processes.
Practical Example (Illustrative)
Ishaan has a ₹5,000 monthly SIP via NACH with a due date of the 10th.
- Normal month: The 10th is a Wednesday. Money is debited and reaches the scheme before 3:00 pm. Units are allotted at Wednesday's NAV of ₹40: ₹5,000 ÷ ₹40 = 125 units.
- Holiday month: The 10th is a Sunday. The debit is processed on Monday the 11th, and units are allotted at Monday's NAV of ₹41: ₹5,000 ÷ ₹41 = 121.951 units.
- Delay month: The 10th is a Friday, but the money reaches the scheme after 3:00 pm. Units are allotted at the next business day's NAV.
Figures are hypothetical; stamp duty is ignored.
Why Is It Important?
- Prevents failed instalments: a due date soon after salary credit means money is available.
- Explains NAV differences: investors often wonder why the NAV on their statement is not the due date's NAV.
- Affects the holding period: each instalment's allotment date starts its own clock for exit load and tax.
- Helps organise cash flow: spreading multiple SIPs across dates can ease budgeting.
Key Features
| Feature | Details |
|---|---|
| Chosen at registration | Changing it usually means cancelling and re-registering |
| Debit vs allotment | Can differ by a day, depending on mandate type and fund realisation |
| Applicable NAV | Based on when funds are available to the scheme before cut-off |
| Holidays | Usually processed on the next business day |
| Multiple SIPs | Can have the same or different due dates |
Benefits and Limitations
Practical usefulness
- A well-chosen date improves the reliability of your SIP.
- Different dates for different SIPs can match multiple income dates.
Limitations
- Changing a due date is often not possible directly.
- No particular date gives consistently better returns over the long term; date choice should be driven by cash flow, not NAV prediction.
Comparison With Related Concepts
| Concept | Meaning | Key difference | Practical implication |
|---|---|---|---|
| SIP due date | Scheduled debit date | Decided by you | Pick a date after salary credit |
| Applicable NAV | NAV used for allotment | Depends on funds availability and cut-off | May be a day later than the due date |
| Allotment of Units | Crediting of units to your folio | Follows the NAV date | Shown in the transaction confirmation |
| Missed SIP Instalment | A failed debit on the due date | Happens if funds or mandate are inadequate | Can lead to auto-cancellation if repeated |
How Does It Apply to Mutual Fund Investors?
- Salary alignment: Choose a date a few days after your salary is credited.
- Multiple SIPs: Spread SIPs across dates if your income comes in at different times, or keep them on one date for simpler tracking.
- Statements: Check the NAV date and units in each Mutual Fund Transaction Confirmation.
- Pause and cancellation: Requests usually need to reach the AMC several days before the due date to take effect. See SIP Pause and SIP Cancellation.
- ELSS: Each instalment's three-year lock-in starts from its own allotment date.
Common Mistakes and Misconceptions
- "I always get the NAV of my SIP date." You get the NAV of the day the money is available to the scheme before cut-off, which may be a day later.
- "Some dates give higher returns." Over long periods, differences between SIP dates tend to be small and unpredictable. Reliability matters more.
- "I can change my SIP date anytime." Many AMCs require you to cancel and re-register to change the date.
- "Holidays mean my instalment is skipped." Debits on non-business days are usually processed on the next business day, not skipped.
Important Terms to Know
- Cut-Off Time and Applicable NAV: Rules that decide your NAV.
- Allotment of Units: When units are credited.
- SIP Mandate: The authorisation used for the debit.
- Missed SIP Instalment: A debit that fails on the due date.
- SIP Registration: Where the due date is chosen.
- Applicable NAV: The price used for your instalment.
Key Takeaways
- The SIP due date is when each instalment is scheduled to be debited.
- The applicable NAV depends on when funds reach the scheme, not just the due date.
- Holidays usually shift processing to the next business day.
- Choose a date after your income is credited to avoid failed instalments.
- Changing the date often requires cancelling and re-registering the SIP.

Frequently Asked Questions
**Which is the best SIP date?**
There is no date that consistently delivers better returns. The best date is one when your account reliably has enough money, typically a few days after your salary or business income is credited.
Why is my SIP NAV different from the NAV on my SIP date? For most schemes, the applicable NAV is that of the business day on which your money is available to the scheme before the 3:00 pm cut-off. Depending on the mandate type and bank processing, this can be the SIP date or the next business day.
What if my SIP date falls on a holiday? The debit and allotment are usually processed on the next business day. The NAV of that business day applies, provided funds reach the scheme before the cut-off.
Can I change my SIP date? Many AMCs do not allow direct changes to the SIP date. You may need to cancel the existing SIP and register a new one with the preferred date. Some platforms offer a modification option; check with your AMC.
Can I have two SIPs on different dates in the same scheme? Yes. Many investors split their monthly amount into two or more SIPs on different dates in the same scheme, subject to each SIP meeting the minimum amount.
