When starting a Systematic Investment Plan (SIP), investors often wonder whether daily, weekly, or monthly SIPs are more profitable. The SIP study by White Oak Capital Mutual Fund provides valuable insights on this frequently asked question.
💡 Quick Answer
Monthly, for most investors. In the White Oak Capital study of the BSE Sensex TRI, daily, weekly and monthly SIPs of the same total amount produced XIRRs of 14.61%, 14.60% and 14.59%. The returns are effectively identical, so choose the frequency that fits your cash flow and is simplest to manage.
Successful SIP: The Smart Investor’s Choice!
A successful SIP is more about “Starting Early”, maintaining the discipline of “Investing Regularly”, investing for the “Long Term” to achieve our “Financial Goals” and less about “Which Date”, “Which Frequency”, “At what stage of the Market Cycle” etc.

Data Overview: SIP Frequency Comparison
| SIP Frequency | SIP Instalment Amount (₹) | Total Amount Invested (₹) | Current Valuation (₹) | XIRR (%) |
|---|---|---|---|---|
| Daily | 1,000 | 68.82 Lac | 7.81 Crore | 14.61% |
| Weekly | 4,753 | 68.82 Lac | 7.83 Crore | 14.60% |
| Monthly | 20,667 | 68.82 Lac | 7.85 Crore | 14.59% |
Key Insights:
Similar Returns Across Frequencies:
- The XIRR (Extended Internal Rate of Return) difference between daily, weekly, and monthly SIPs is marginal, indicating that the investment frequency has little impact on long-term returns.
- Monthly SIPs offered the highest valuation at ₹7.85 Crore, though the difference was negligible compared to daily or weekly SIPs.
Simplicity Over Complexity:
- Managing multiple SIPs, especially daily ones, can be operationally complex due to frequent debits and potential administrative issues.
Cost Averaging Impact:
- While more frequent SIPs theoretically provide better cost averaging, in practice, market fluctuations even out over time. The same study also found that the SIP date you choose makes almost no difference to long-term returns.
Best Approach:
- Since the return differences are negligible, selecting a monthly SIP is a simpler and more efficient strategy for most investors.
Inference:
The historical data suggests that SIP frequency—whether daily, weekly, or monthly—does not significantly impact long-term returns. The critical factor is maintaining investment discipline and investing regularly over a long period. Over a long enough SIP investment horizon, the odds move firmly in your favour.

Conclusion:
Investors should focus on starting their SIPs early, maintaining discipline, and investing regularly. Whether you choose daily, weekly, or monthly SIPs, the long-term returns remain nearly identical. Thus, it’s more important to select a frequency that aligns with your cash flow and convenience. If your income rises over time, a SIP top-up is the next lever to consider.

Key Takeaways
- Daily, weekly and monthly SIPs of the same total amount produced XIRRs of 14.61%, 14.60% and 14.59% in the White Oak Capital study of the BSE Sensex TRI.
- Monthly SIPs ended with the highest valuation at ₹7.85 Crore, though the difference against daily and weekly was negligible.
- More frequent SIPs theoretically improve cost averaging, but in practice market fluctuations even out over time.
- Managing many SIPs, especially daily ones, adds operational complexity through frequent debits and possible administrative issues.
- Because the return differences are negligible, pick the frequency that matches your cash flow and is simplest to keep running.
Frequently Asked Questions
Which SIP frequency gives the best returns?
None of them meaningfully. In the White Oak Capital study, daily SIPs returned 14.61% XIRR, weekly 14.60% and monthly 14.59%. The difference is marginal, which indicates that investment frequency has little impact on long-term returns.
Is a daily SIP better than a monthly SIP?
Not in terms of returns. Daily SIPs returned 14.61% XIRR against 14.59% for monthly, while monthly SIPs actually ended with the highest valuation at ₹7.85 Crore. Managing daily SIPs is also operationally more complex because of frequent debits and potential administrative issues.
Does a weekly SIP improve rupee cost averaging?
In theory more frequent SIPs provide better cost averaging, but in practice market fluctuations even out over time, which is why the weekly XIRR of 14.60% sits between the daily and monthly figures rather than above both.
How much was invested in the SIP frequency study?
Each frequency invested the same total of ₹68.82 Lac. The instalment sizes were ₹1,000 daily, ₹4,753 weekly and ₹20,667 monthly, ending at valuations of ₹7.81 Crore, ₹7.83 Crore and ₹7.85 Crore respectively.
Which SIP frequency should I choose?
Since the return differences are negligible, a monthly SIP is the simpler and more efficient choice for most investors. Select a frequency that aligns with your cash flow and convenience, and focus on starting early and investing regularly.
