Retirement planning is also not a one-time exercise. As careers progress, incomes rise and personal circumstances evolve, it is important to review retirement goals periodically. Investors may choose to increase their SIP contributions after salary increments, bonuses or other financial milestones. Small increases made consistently over the years can make a meaningful difference to the size of the retirement corpus. Retirement portfolios should remain aligned with an investor’s age, risk appetite and financial objectives. Depending on these factors, investors may choose to spread SIP investments across different mutual fund categories to build a diversified portfolio. Younger investors may have a longer investment horizon and greater ability to withstand short-term market volatility, while those approaching retirement may gradually recalibrate their asset allocation to balance growth potential with stability.
