SIP Investment: For mutual fund investors, the choice between daily, weekly and monthly systematic investment plans (SIPs) is often linked to cash flow and investment convenience. But an analysis shows that the frequency of investing may not make a significant difference to long-term returns, experts told Zee Business.
The comparison was based on the BSE Sensex TRI from 1996 to July 2026. According to the analysis, when the same total investment was divided across daily, weekly and monthly SIPs, the total amount invested was around Rs 10.94 crore.
Daily vs weekly vs monthly SIP: What did the analysis show?
According to experts, the analysis showed that the investment value in the daily SIP scenario was around Rs 12.61 crore, with an Extended Internal Rate of Return (XIRR) of 13.53 per cent.
For the weekly SIP, the investment value was around Rs 12.62 crore.
In the monthly SIP scenario, the investment value was around Rs 12.73 crore, with an XIRR of 13.53 per cent.
| SIP frequency | Total invested | Approx. value | XIRR |
|---|---|---|---|
| Daily | Rs 10.94 crore | Rs 12.61 crore | 13.53% |
| Weekly | Rs 10.94 crore | Rs 12.62 crore | No very big difference |
| Monthly | Rs 10.94 crore | Rs 12.73 crore | 13.53% |
The monthly SIP generated a slightly higher corpus in rupee terms in this particular comparison. However, the difference was marginal, while the XIRR for the daily and monthly SIP examples was the same at 13.53 per cent.

What did experts say about SIP frequency?
Financial expert Pankaj Mathpal, MD, Optima Money, explained that the difference between daily, weekly and monthly SIPs is more related to investor behaviour than a major difference in wealth creation.
He said there is no specific “right time” to invest and stressed the importance of starting early, remaining disciplined and continuing investments over the long term.
Mathpal also explained that comparisons of daily, weekly and monthly SIPs do not show a separate or significant advantage from simply increasing the frequency of investment. Investors should instead invest according to when the money is available.
The BSE Sensex TRI comparison reflected this point. While the monthly SIP showed a slightly higher value in rupee terms, the overall XIRR remained nearly the same.
Daily and small-ticket SIPs: Why are they gaining popularity?
Certified Financial Planner Poonam Rungta said daily and small-ticket SIPs are also gaining attention because digital transactions have made it easier for investors to invest smaller amounts more frequently.
She cited examples such as Rs 250 micro-SIPs and Rs 100 monthly investments, while daily investments of small amounts have also become easier.
According to Rungta, such investments can help increase participation, including among investors in Tier-2 and Tier-3 cities and lower-middle-income groups.
However, she cautioned investors against blindly following the trend. She said investors should understand their financial goals, risk appetite and investment horizon before choosing an investment approach.
Does the SIP date impact returns?
Experts also examined whether choosing a particular SIP date makes a significant difference to long-term returns.
For the BSE Sensex TRI from 1996 onwards, SIP dates between the 1st and 28th were compared consistently. The analysis found that the lowest XIRR was 13.50 per cent, while the highest was 13.56 per cent.
This indicates that the difference arising from the SIP date was very small in the example.
Mathpal said investors should therefore choose the SIP date based on their cash flow rather than trying to identify a particular “good” or “bad” day.
For salaried investors, an SIP date between the 1st and 5th of the month, after the salary is credited, can be considered based on their cash flow. Investors with uneven income can choose a frequency according to when they receive money.
Daily, weekly or monthly SIP: What should investors consider?
The explanation suggests that investors can choose their SIP frequency based on cash-flow convenience and discipline, rather than assuming that a higher frequency will automatically generate significantly higher returns.
A salaried investor may find a monthly SIP convenient after receiving the salary, while someone whose income comes in parts may prefer weekly or more frequent investments. Daily SIPs can also facilitate smaller-ticket investments.
At the same time, the long-term BSE Sensex TRI comparison showed only a marginal difference between the daily, weekly and monthly SIP outcomes when the total investment was comparable.
The experts also highlighted the importance of asset allocation, selecting the appropriate fund, reviewing and rebalancing the portfolio, and staying invested for the long term.
The comparison is based specifically on the BSE Sensex TRI and the outcome could differ for another index or investment period. The example nevertheless shows that, in this historical comparison, SIP frequency did not materially change the long-term return outcome.
