Building a Rs 5 crore retirement corpus on a Rs 50,000 salary is achievable with disciplined investing, time and strategy. Investing 30% of your salary monthly via SIP may take 31 years, but a 7% annual step-up can cut it to 25–26 years. Experts say higher savings, better returns and periodic reviews accelerate wealth creation, while asset allocation and risk appetite play a crucial role in long-term success.
