Mirae Asset Mutual Fund's 'Rule of 1% Upgrade' boosts retirement corpus to ₹2.83 crore vs ₹1.82 crore from a standard 1% SIP hike over 25 years.
Many investors set up a systematic investment plan (SIP) with a fixed amount and never revisit it, even as their salaries rise. Over time, that fixed contribution shrinks as a share of income, potentially undermining long-term goals.
Mirae Asset Mutual Fund, in its latest M-FinBytes report, proposes what it calls the "Rule of 1% Upgrade." The idea is simple: each year, increase the percentage of income directed to SIPs by one point, rather than raising the absolute SIP amount by a small fixed percentage.
"The Rule of 1% Upgrade is not about making a dramatic jump. It is a yearly nudge: increase the share of income directed towards investments by one percentage point, subject to affordability, financial goals, and overall circumstances," the fund house said.
Consider an investor earning ₹1 lakh a month who starts with a ₹10,000 monthly SIP, or 10% of income. A 1% increase in the SIP amount lifts the contribution to ₹10,100. A 1% upgrade in the allocation – from 10% to 11% of income – pushes the monthly SIP to ₹11,000, assuming income stays flat.
The difference compounds over time. Mirae Asset ran the numbers for a 25-year horizon at a 12% annual return. Under the standard 1% annual SIP increase, the investor contributes roughly ₹33.89 lakh and builds a corpus of about ₹1.82 crore. Under the 1% income-upgrade rule, total contributions reach about ₹66 lakh, and the corpus hits nearly ₹2.83 crore.
"The appeal of this rule is its modesty. It does not ask the investor to overhaul the household budget overnight. It simply creates a yearly checkpoint where investing gets a small promotion too," Mirae Asset MF noted.
The strategy works because it ties the investment amount to income growth, even if the income itself does not rise. The percentage-of-income approach ensures that the SIP keeps pace with the investor's financial capacity, rather than drifting lower in real terms.
