One investor earned Rs 1 lakh more from same SIP
Imagine two friends who both save Rs 5,000 every month in the same collection of company shares for six years.
One starts in January 2011, the other in January 2016.
The first friend ends with about Rs 7.16 lakh, while the second has about Rs 6.13 lakh, even though both put in the same Rs 3.6 lakh total.
Why?
The stock market goes up and down like a roller coaster.
Where you start on the ride changes what you experience first.
When prices fall, the same Rs 5,000 buys more pieces of the fund.
Buying at many different prices over time is called rupee cost averaging, and it smooths out the bumps.
The earlier starter went through a market dip first but stayed invested, so those cheap purchases helped him earn more.
The point is not to guess the perfect time to start, but to keep investing through good and bad times.
Two investors each invested Rs 5,000 monthly in HDFC Mid Cap Fund for six years, one starting January 2011 and the other January 2016.
The 2011 starter accumulated Rs 7,16,000 with a 23.41% XIRR, while the 2016 starter ended with Rs 6,13,000 and an 18.05% XIRR, after each invested Rs 3,60,000 total.
Different starting points meant different market cycles: a Nifty 50 fall of around 24.6% in 2011 versus the 40.69% COVID-era drawdown on the fund.
The fund recovered to its pre-COVID peak by 26 November 2020, 248 days after the March 2020 trough, rising 66.31% from the low.
Arjun Guha Thakurta of Anand Rathi Wealth says staying invested across market cycles matters more than timing, because rupee cost averaging buys more units at lower NAVs.

“For a long‑term SIP investor, however, this starting point effect becomes much less important. Every instalment buys units at a different NAV, including during periods when markets are falling. That is the real benefit of rupee cost averaging.”
