Daily, Weekly, and Monthly SIP: Factual Returns
1. Introduction to SIP Frequency Options
Mutual fund platforms in India provide multiple scheduling frequencies for Systematic Investment Plans. While the traditional monthly frequency remains the industry standard, Asset Management Companies (AMCs) permit daily, weekly, fortnightly, and quarterly debit options.
From a mathematical standpoint, changing the frequency alters the compounding interval and the granularity of Net Asset Value (NAV) averaging.
2. Review of Historical rolling Returns
Historical market studies analyzing equity benchmarks (such as the Nifty 50 TRI) over extended durations (5, 10, and 15 years) demonstrate that the return profiles of daily, weekly, and monthly frequencies converge closely.
The table below outlines historical rolling return indicators observed across various investment tenures:
| Investment Period | Daily SIP Return (CAGR) | Weekly SIP Return (CAGR) | Monthly SIP Return (CAGR) |
|---|---|---|---|
| 5-Year Rolling average | 12.14% | 12.16% | 12.11% |
| 10-Year Rolling average | 12.43% | 12.45% | 12.41% |
| 15-Year Rolling average | 12.82% | 12.83% | 12.79% |
Historical rolling return statistics show that the performance differences between daily, weekly, and monthly frequencies generally fall within 4 to 7 basis points (0.04% to 0.07% p.a.). This minor divergence occurs because the long-term trend of the underlying index averages out short-term price variations, regardless of whether purchases are made daily or monthly.
